Hi all I'm the newest Newbie!

[NaughtyGT]

Hi all!

I just picked up a Relic 88 323GT rigi-dig! Re-painted in original White/Pink Pearl & Black/Purple Pearl....um NOT good choice but orig scheme! Has had Exedy 5 Spokey installed bout' 7-8 months ago

Mostly stock except following:

BOV
Adjustable Boost Controller to 12psi (I think), running 9 @ moment according to seller?
5 Spoke Clutch (bitch to use), finally releases when it's ready but waaaay cool for free
Mags but 1 was stolen :( soooooo, will be gettin another set soon, spare is in use for now:cool:
I just put 21/2 Cat-back on Friday as it had crimped pipe (instead of hotdog) & one of those pathetic oversize, ugly chrome end pipes,,,eerrrrrrkkkk! God only knows whatgets into peoples' minds.

I will wack up some pics later this morn & it is going to be a project from here but it is registered & drives great. Body excel, interior VG for age. I'm thrilled top say the least

Buggered if I know what else cause I want it add-ons only, stock turbo & Engine cause I don't wanna bugger originality too much except the car is on stilts due to Elec dash-adjustable Suspension, again, eerrrrkkk! I'll have to get some advice on what, how to lower effectively soon.

By for now & hey, great forum!

hello and welcome to astinagt.

GT or GTX? I'm assuming it's a BD/BF model 323? 2 doors? 1.6L?

[NaughtyGT]

88' BF GT(SS in AUS) 3 Door B6T FWD rare model

I'm from G/Coast, how is it up there?

[70NYD]

wellcome to AGT
its FREEZING up here

[project.r.racing]

its FREEZING up hereharden up ya big girl :p

it's a warm sunny winter's day.

[70NYD]

i meant in general :p thursday morning i woke up with ice on the cars :eek:
and ur a few degrees north of me any way, ur closer to the equator :p

[so fresh]

Welcome And Yayeeeeeaaaaahhh!!!
Another Vic! :D:D :D

hello and welcome to astinagt.

GT means 2WD, GTX means 4WD.

I saw a 323GT with original Mazda factory Rally paint scheme being towed up the north coast on one of our last cruises. It's very rare to see these, so I was happy this one was being towed to preserve it. :p

As some ppl know, the 323GT (Rally edition) is my favourite 323 of all time. So if you have one of those, I can't wait to see your pics! I've tried to preserve the originality of mine too (errr, well mine is a KE TX3). So I have only strapped an IHI VF10 with Corksport IC on there with 2.5" piping to go on yet. But the interior and paint will remain original when complete. Unless I go stupid and cage it with racing seats. :p

Velkommin,
Gav.

[NaughtyGT]

I'm dying to mod it all up but cause' it's so original, I'm in the middle a bit & need to see how I go. The rally suspension just looks outta touch with low cars of today, know what I mean?

BTW, It's alot colder down here in Vic 70NYD, like 6 deg mornings is usual. I've been here 3 1/2 years & the other winters were mild but not this lil' beauty weather.......shhiiiiiittt!

[project.r.racing]

I had 1.5 deg thurs morning.

i'd probably replace the springs and struts for lowered and short gear.

[Rupewrecht]

Welcome to AGT!

Sounds interesting! Pics please :)

[NaughtyGT]

I prob will lower it but definately keep orig sus' for keep sakes. Just need to get finances up first.

Main perf' mods I want to do up ahead is bigger, better FMIC & straight through cat or no cat (is this viable/practical) & I'm chasing a set of mags as 1 was recently stolen when seller owned it & I need tyres soon for RWC anyway so I may as well get wheel set now.

[chicaboo]

You need to keep the cat to be legal (post 1986). Corksport do an upgrade IC in the stock location, but it has 2.5" inlet/outlet. You can use 90 degree silicone bends with s/s reducer cones to get around that. You can also put a BG GTX BPT dump pipe on there and get a new down pipe and mid pipe with hi-flow cat made up too. All your intake and exhaust piping is 1.75" stock, I'm going with 2.5" on mine. I suspect this is too big for my intake side, but it's too hard getting it all in 2.25", which I believe would be ideal.

Gav.

EDIT: If your motor has the "boxy plenum", then you prolly also hav a 4 bolt exahust housing on your VJ6/11 turbo, in which case you can't use a BPT dump pipe without using the 15R exhaust housing from VJ20 also. And that requires elongating the bolt holes to the exhaust manifold. Which is a fair bit more stuffing around... Or you could get a 12R exhaust housing from a VJ14 turbo, but that means getting stuff from 2 different sources.

Turbo is a VJ14 with 3 bolt exhaust housing!

So, even cooler for mods:D

[NaughtyGT]

Hey Guys, here are the pics, car is bit grubby so ignore photo imperfections, real smick in real life:D

[70NYD]

ooooh sexc :D

[project.r.racing]

omg it's a panda.

some black rims would be a good replacement. 15x6.5 w/ 195/50 tyres.

sunroof/moonroof too. nice!

interior is how do i say... 80s. reminds me of my old kc laser.

[NaughtyGT]

I know the interior is oldschool, later model interior like KE Laser was alot more compatable for today but, that was 88'

[4ORGD]

welcome to AGT.. i remember seeing this car for sale does it have one odd rim??

[chicaboo]

The seats in the KE weren't as hugging as the BF's, but the 2 tone grey material with red piping (mine is magenta now :p) was nice.

Gav.

[NaughtyGT]

4ORGD? welcome to AGT.. i remember seeing this car for sale does it have one odd rim??

Yeah that's it, it looked crap on advert but, up close it is the real deal! I overlooked it for weeks wanting another & checking out 2 others for sale. A GTX & another GT but they wern't in the hunt. This has fresh paint & exedy clutch so, no comparison to others, the other GT body was iffy & had been painted in the backyard of a drug dealer I think?:D

I am facinated with the Astina GT, have you got one? How many were actually made? I heard 20? Is his true? I loved the stock production cars when they were new back in 92' when I was detailing stock ones for a major MAZDA/VOLVO dealer in Mt Gravatt, Brisbane QLD! They were a tight suspensioned lil dude mainly in Crimson or Torguoise colour. I am guessing the GT was a 1.8L BPT motor basically?

hey project.r.racing

These were an old-school maniac lil car really for their day! Bit underpowered if compared to VR4's or the likes today but, will still hang in there with Supra T's & V8 C'dores if driven right, read on the web the times they used the B6T in the Festiva's etc too. Check this, the only bad rap they got by car watchdogs was: "too much torque for a 2WD car that light,,,,hahahahaha, what about today's cars man, WOW, they'd ave a fit.

Bit a' History for anyone interested in the oldies???,,,,From 82'-85' BD models (possibly pre-82' but don't know much about these) Mazda had these 323's to offer:
a) Stock 1.3L 4 speed (beat Snails & the odd GrassHoppers), then,
b) 1.5L with 5 Speed, hmmmm (good, reliable motors, yes)
c) SS Model, wooooowww, 1.5L had twin Carbs, I actually owned a real knocked-about one, remember boggin the right rear q'ter panel for RWC, hehehe, but they hammered for they're day, rev out oK!
d) Enter the DS (Deluxe Special) they come in Autos too, not too bad though, yep, had one of them too, (Auto to boot!) in pretty good nick. Had Elec S/Roof, PS & A/Con & woven seats. Mine was Silver with Black/red Interior.
A mate also had a Black Laser S (exact same as Mazda SS). Noone knew of the SS just the Laser S in Aus back then!

86'-89' era of the BF's ---- NOW....The GT & GTX were the only I know of that had Elec Windows, standard anyway for there day.
So, GT & GTX came standard with following:
Electric Windows; Electric Sunroof; PS; Air/Con; 4 Wheel Disc Brakes & only option I know of was the Rally-Suspension-Pack that mine has.

Also, generally, for those that don't know,,,,, GT's were the FWD (2WD) version of the 4WD GTX's, ((as pointed out earlier by chicaboo)) fitted with B6T engines (1.6L DOHC 16 Valve F/Inj Engines coupled with IHI Turbos) mine has VJ14 Turbo, although some were less fortunate with the lesser spec turbos they come out with (10s, 11s,12s etc). These FWD versions are rarer (only made for 1 year?) & quicker (due to being >120 kgs lighter) than the GTX! To be fair though, the GTX was purpose built for the rally track & would outhandle the GT anyday but, on a straight-line, the GT was almost 1 sec quicker to 100kph!

The PUZZLE is::: There is no literature I know available on these atual GT Hatches ebver being made! FIGURE?!?

If any of this is wrong pls let me know?

Long-winded but, I hav'nt owned one of these ol girls for sooo long & we just bought a Chrysler PT Cruiser for my wife, cause she loves them & always wanted one,,,,,dear dear I know....like drivin' a tank but, has some coolness & looks great I guess. Funny thing is,,,,when I'm drivin PT, I wish I had the 323 to stick up peoples rear that **** me on the road REGULARLY, or overtake them at least. YOU CAN NOT OVERTAKE ANYTHING IN A PT CRUISER, BEWARE & NEVER TRY OR YOU MAY DIE!!!!!!!

P.S. Thanks all for quick response & the great welcome you guys gave me yesterday, proves your a great bunch, Cheers!
Catch up soon

[project.r.racing]

my bro had a 323 deluxe special as his 1st car. blue interior, central lockig, 1.5L auto, 82 model.
and a friend had a 2 door Laser S with a twin carb E5 motor.

but i think BDs didn't come on the market until 1985/86? then BFs were 87/88?

//edit// I'm so not up with my 80s 323s. BDs came out in 1980? Same as KA/KB Lasers?

Yep, If I remember, 82-85 was BD (1.5 SOHC) then, 86-89 were the BF (1.6 SOHC) models. I'll do some checking, they all started about 1980 with the wedge-shaped look & FWD for the first time. I've only owned them 82' models & up!

[NaughtyGT]

DOES ANYONE ANYWHERE NO HOW THESE 2 Door Hatch 2wd GTs' CAME ABOUT???????

No Mazda early literature has them mentioned, only in 4 Door Sedan
Model! Even 323 Forums have inconsistent data etc:confused: :confused: :confused:

any idea chicaboo?

btw, is it cold up in Q'Land....Im puttin Central Heating on now man..........frig!

[chicaboo]

I think the 2WD GT/Turbo was just released as an economical option for those not wanting the expense of the 4WD package. Ford went a step further by not putting the adjustable suspension on the 2WD Turbos as well. So it was just an intermediate package between the NA and 4WD turbos.

Its about 9C by the time I'm driving to work in the morning, so it's prolly 3C or so colder at 5am or thereabouts.

Gav.

[NaughtyGT]

still don't make sence Gav, the GTX came out in 87' & GT in 88', the sedan GT may have come out in 86' but not the hatch, I'm after info on the hatch
Stretchin the memory, I'm sure they had a Laser Turbo in the KB series approx 84', woulda been attache to the 1.5L

Gav, are you in Logan Bris? I lived in Springwood & Rochedale for 15 years man, cool!

[chicaboo]

The first turbo Laser was the E5T powered "White Lightning" KB Laser in 84 or 85. The KC was atmo only, and then in 87 the KE TX3 Turbos were released.

Yeah mang, I live in Logan, and also lived at Mt Gravatt East for a few years too. I miss MGE, I hate living in Logan these days.

Gav.

[NaughtyGT]

that's so cool Gav, I been up MGMountain a few times, & down hehe Garden City was my hang for shopping, Can't beat Mt Tambourine though for winding fast ey? Yeah, Logan sux a bit, Woodridge & Kingston now they're treats aint they what? Coppers are real good, NOT. Anyhow yeah the ol' white lightnin' wooohoooooo hang on to ya nuts! SOHC job some even mated engine with carb/s eeeooooww, Inj ones woulda been OK I suppose compared to Sigmas back then hahahaha. Still, a relic is a legend is a relic (maybe even if in it's own right anyway)!

P.S. That info above was merely off top of my head

Great to chat with someone from my ol' woods cool! I grew up in Springwood & Rochedale. That's where I cut my teeth so-to-speak, teen years

Awesome, I do miss Brissy sometimes

[NaughtyGT]

May just keep the stock stilted suspension after all, it slams through rough corners & potholes, so cool, just gotta get used to the ride height, bloody fun though yeeeehaaaaar :D

[chicaboo]

I don't think the height is that bad. I have the Dobisport lowering springs on mine and I hate them with a passion. They give extremely good handling and balance, but are rough as guts to live with. I will be putting stock springs back on soon. The car will go back to being undsteerish after that, but I will be able to tolerate them.

Gav.

[NaughtyGT]

Agreed Gav! I think I'm already growing to like the ride. My last car was so low & stiff, you needed a kidney belt for the dips & "potholes", sheeeeeeiiiiitttt! Almost poop yourself hehehe

You've sold me, at least it will remain a little stock & save $$$ which I could do far better things with, at least for now......but for right now, I'm going to relax & have a stout Beer, catch you soon!

[NaughtyGT]

Guys, after chat with my Mechanic mate, decided I'm going to pull Air/Con unit out so I can customise the Turbo & Mandrel bends. The stock Turbo has severely restrictive stock exhaust set-up which doesn't allow for much change & certainly doesn't warrant the money to do a half-job. Will be a bigger job than anticipated but better in the end. I now need to research the best Turbo or Hybrid out there & then couple Mandrel bends to suit. I want to do it right the first time!

[chicaboo]

Is your turbo stuffed??? If it is, there is a soft/cheap option, which is what I have done. ie: VF10/VJ14 hybrid with custom coolant lines, stock BPT dump and Corksport IC/2.5" plumbing.

Otherwise, there are at least 2 nice exhaust manifolds on ebay that I like. One is a nice spaghetti s/s job for T25/28 turbos, which looks like it would make some great power. The other is a cast manifold to suit T3/4 flanges, which you can still add a T25/28 onto anyhow. I sort of like the cast option myself, as I know it won't crack and the space for it looks better.

Both of those options give you room for a split dump while keeping your AC. AC really is only a problem if you go with a custom split dump with an IHI hybrid while keeping your stock exhaust manifold. So, you don't need to sacrifice your AC to make big power.

Gidday chicaboo!

the turbos' not stuffed but I have been warned that the stock exhaust side that is flanged, where you join the dump pipe, turns downward too early & thus, on too sharp an angle, so, to overcome this short-coming, you come out longer horizontally & avoid the sharp downturn, ending up with better, gentler curve before bending down & then agian bending towards the rear of car! The A/C is in the way & causes you to bend too soon thus, constricting the flow! I would rather go all-out & have the best flow than compromise!

To use the BPT dump, I would have to use hybrid turbo wouldn't I? cause VJ14has 3 bolt flange pattern!

[chicaboo]

Hey mate,

The BPT dump is a great upgrade, it has nice square edges (which for some reason almost always flow better :confused:), and it's outlet is 2.25" as opposed to 1.75" on the B6T dump. Oh, and you get an extra place to bung in an exhaust temp sensor or such. :) I've seen some nice custom split dumps that will fit with the AC in place, so I think removing the AC is a big deal when these options are available to you. Also, 18" long split dumps are great with bigger turbos, but they won't gain you as much value on a small VJXX to warrant losing the AC IMO...

The VJ14 should have a 5 bolt pattern (you may only see 3 from above), and the VJ11 have a 4 bolt pattern (I've got both sitting here in my garage). Once you know which pattern you have, you can hit put up a FS add on FL.com and see what sort of response you get back. I know AC friendly split dumps have come and gone on there in the past.

Gav.

ahhh, I'll check again in the morning, that explains the BPT dump pipe suggestion then! So to clear up, the BPT dump is available & it joins straight to the VJ14?, no need to change T-housing or anything & I can leave the AC in? I didn't think the BPT dump fitted straight on the VJ14?

btw, Turbo is definately a VJ14! I used a torch & read it on the serial plate

[chicaboo]

I've got a VJ14 5-bolt 12R exhaust housing with a BPT dump attached and it clears the AC by 1cm I guess. It will be fun getting the heat shield back on after I've polished it though. :p

Another trick to getting yet more flow again with stock parts is to use the VJ20 15R exhaust housing and elongate the 4 bolt holes that go to the exhaust manifold to make it fit. Perhaps a bit much stuffing around for a small gain, so I would only do that if you have a 4 bolt housing...

And then there is a 20R exhaust housing, but I don't know much about them, except they have yet more flow again. Which is not necessarily a good thing if you like response at low revs.

Lots of options...
Gav.

[NaughtyGT]

put simply, what confuses me the most @ this stage is I have the orig' VF14 right, what is the 12R you mention? Will the Corksport downpipe/dumppipe fit on mine? I thought it was for the BPT Turbo?

What mods do I have to make then if I keep Air/Con?

(btw, I have een reading some old posts of yours on your mods etc, I am still learning T's though)

[chicaboo]

Oh $#!T, you'll go nuts reading my old posts! :p

The Corksport dump will fit any 5 bolt 12/15/20R housing, but your AC and sump will get in the way on the B6T engine. You can delete the AC, but I can't garuantee that the CS dump will clear the sump without modification.

12R is the size of the housing for the VJ14, and 15R and 20R were on the VJ20. Basically the port is bigger to the inducer from the exhaust manifold on the 15R and 20R. But by making the port bigger you lose response at low revs.

You might be interested to know that I have stumbled onto a cheap stroker kit in the US and a guy that can custom grind B6T cams. :D I'm still sussing out the cam guy, as he does something fishy to make the welds stand up to regular driving, which means getting cam gears... I will let you know more when I do.

ohhhhhhhh, leaving that alone for now:eek: you do it, then, I'll put my straight-Jacket back on out of the closet &......hehehehe

I now know wtfrig your talking about, I'm a quick as learner but, I couldn't get my head under the car to check out what is what til' I jacked it up prop! The heat shield is a biiiitttcccchhhh!!!!!!!!!!

Here goes:

Dump pipe = 5 bolt housing from hot-side to 3 bolt flange right?
Downpipe = from 3 bolt flange down to cat! Right???

CorkSport is a dump/down pipe in one, correct?

Now, my guess is you would have to remove AC comp' to fit Corksport dump/downpipe. How'm I going so far?

But, your not sure if CorkSport will go straight on the hotside, again I'm guessing due to constrictions, without mod? What would the worst-case mod be???

P.S. Incidently, the intake pipe where it joins down on the Coldside is friggin small diameter, how do you get more air into it??????????

I'm also guessing that you didn't use the CS pipe ey?

[chicaboo]

When I say dump, I mean the piece immediately off the exhaust housing on the turbo. When I say down pipe, I mean the pipe that drops down (after the dump) from under the sump to the midpipe/cat. Yes you are correct, the dump is 5 bolt to the exhaust housing and 3 bolt to the down pipe. Hover just to further complicate things, the BPT dump is 4 bolt to the down pipe! :p I have a couple of flanges already made up for that.

Nup, no CS dump for me, I am keeping my AC! So I just used the BPT dump as it's 5 bolt and bolts straight up to my exhaust housing.

Alright, the inlet pipe into the compressor is commonly refered to as the saxophone or J pipe. It's small, but is still 1.75" as per the rest of the system, so I wouldn't get too worried about that until you upgrade. I've actually replaced my saxophone with a straight 2.5" s/s pipe to a 90d sillicone bend to a 2.5">2.25" s/s reducer welded into a flange bolted to the compressor that sits over the 2" inlet of the compressor. :) This gives a nice gradual step down into the compressor without too many huge ledges. It can be done otherways, but usually involes modding the compressor to have a snout pressor or welded into the end of it. :eek:

2 Q's:

1) Where do I get a BP pipe cause I originally thought you meant the CS one not the orig' Mazda one!

2) Gimme one of your flanges ppllleeeaaasseee!!! Pretty pls, whatta I have to do....aaaarrrgggg?

I'm alright now, composed, yeeeep! So, will you part with the flange already????:D

P.S. Back to the inlet, is it 1.75" or 2", you mentioned both?

[chicaboo]

1. You just need to find someone nice selling a BPT dump pipe.
2. We will talk about this after you get a BPT dump pipe. :p

All the VJ14 inlets and outlets are 1.75". The VF10 that I have is 2" inlet and outlet on the compressor/turbine, but I expand them out to 2.5" with reducers. And the BPT dump has a 2.25" outlet to the down pipe.

Gav.

[NaughtyGT]

cooooooool!

Well!!!!! Is it worth keeping the VJ14 in your opinion? Or should I go the VF10 (I'm presuming you use complete VF10 Turbo & ditch the VJ14?)

[chicaboo]

The VF10 makes 30% more power or something, so I'd say it's worth it. You slide the VF10 into the exhaust housing from the VJ14. You will need to loosen the VF10's compressor and rotate it to point where you want it to. I have mine pointing straight up like the old VJ14 did, so I use a stock looking arangement for my IC setup. You need to redrill your wastegate bracket when you rotate the VF10 so it still points to the gate flap.

Just run your VJ14 at 16psi and kill it the fun way before you worry about upgrading your turbo. And by the time you've done that you might want an eBay manifold with v-band turbo and external wastegate so you can keep your AC. :D

Gav.

[NaughtyGT]

woow, woow, woooooow.......there you go again, it's a sin you know to tempt people beyond their breaking point,,,,,,,ah damn! What the hell!

There goes those plans (can you hear the paper being crumbled & hitting the side of the bin???)

So, if you keep the original VJ14 housing, doesn't that mean you still have the problematic sharp curve to the dump pipe? or is this OK? Is this where the custom flange you spoke of comes in? for the BPT down pipe? (which your gonna sell me:rolleyes:)

Uh Hum! what is this EBay luvly thing you now speak of? Why would you consider this, because it handles gases better?

Hold the phone!.....why wouldn't you want the exhaust side opened up? Is that because you'll compromise low-end performance?

BTW, VJ14 is pumping out 10 pounds @ moment in every gear, that's all. I'll tweak boost controller to 12 (this apparently is it's limit?)

[chicaboo]

Here is a pic of the cast and spaghetti manifolds below. Their flanges face upward and forward slightly, so the turbo would sit closer to the bonnet, giving you the height you need to run a custom dump pipe out and dodge the AC. Although the offset on the flange going to the right isn't the best...

Don't let me tempt you on a full upgrade, as there is a lot you can do to get some performance out of your stock VJ14 while keeping your AC. You can MBC it to 11psi (boost cut comes on at 12psi), do the BPT dump pipe with the square shoulders (didn't you say had a custom dump already?), and also adding a dual pass intercooler (pipes are both on the same side) behind the front bumper. If you are going to run more boost, I reckon 2" IC piping would be great for getting the most out of your system too. I have a chipped ECU that has boost and fuel maps up to 18psi, so that's something else you could look at.

Open up the exhaust side? Do you mean using the bigger 15R or 20R housings? I think they would be too much stuffing around unless you already had one. However if you got a dead VJ20 with dump and all, you would have all the goodies you need, just elongate the holes to make it fit. But I would only do that to a VF10/12 hybrid, not to a VJ14...

oooooooooh I luvs!

looks tuned-length to me (sorry, old-school slang)

What I meant when I said "Open up the exhaust side" was do you use only the compressor of the VF10 & couple it to the VJ14 exhaust? If so, aren't you still restricted with the hotside? What I mean is: the Hybrid will increase inlet right, but the exhaust will remain stock? Sorry if I sound Turbo dumb, why couldn't you use the whole VF10? Why use only the cold end? Is it best to make hybrid?

Told you I was dumb!

Been away from Turbos tooooo long!:o

[chicaboo]

Number 1 looks pretty short compared to the others, so I would say they aren't tuned length, but I don't think it matters a rats either.

Oh, that sort of open up... You just swap over the entire VF10 turbine/compressor into the VJ14 exhaust housing. The inducer wheel on the VF10 turbine is still only the same size diameter as the VJ14, but the blade pitch might be different? Anyhow, you get more effort off the VF10 compressor for the same exhaust flow as compared to the VJ14. When hybriding you need to port out the wastegate a bit too. I think mine went from 14mm to 21~23mm diameter when it was ported. Apparently the VF10 spikes badly if you don't do that. But if you go too big with the porting, you get too much pressure against the gate, and it creeps open causing your boost to drop off. That's supposedly not a problem if you use the stock VJ14 gate flap (like I did).

It's certainly alot for me to take in, food for thought....I just want to make this lil beasty go for all it's worth!

[chicaboo]

Oh you do eh? :p

Well, I've been talking to the cam guy down south a bit more, and it seems he can grind my spare cams and shim up my new HLAs to suit the reduced base circle at least. I'm waiting to hear back how much he can do this for. And it's not like he can rip me off as I know what shims and grind cams is worth closer to home. But he is convenient if he can sort out the shimming straight up, which is the pain in the butt part of the process. This is the mod I've really been wanting to do to the car since starting to restore it. :D

Anyhow, I have some pie in the sky things down the track I want to do, like 90mm stroker crank and seriously overbored pistons from a place in the US that seems to be spot on the money. My stock B6T rods are epiqué, so I will just re-use them as the wrist pins will be raised in these pistons. If I can get to 81mm bore safely, I will be looking 1855cc with a VF10 and agressive cams. All this with a microtech or other less gay engine management should have me staring down the barrel of over 180kW ATW. :) The VF10 is going to be limiting me though. So if it dies (and I will dam try to kill it), I will then upgrade to a GT2871 with external wastegate, etc. That should get me over 200kW ATW. Well, that's a long time away, and a lot can go wrong in the mean time, so I'm just taking it one step at a time (very small steps at that!).

1 small step for man.........1 giant leap for Mazdakind:D

When doing the VF10 upgrade, do you need the ECU chipped @ that stage or will it run with the B6 stock ECU?

You can run the VF10 with the stock ECU up to 10-11psi (boost cut at 12psi). If you chip the stock ECU, you can go to 16psi, but anything over is just blowing hot air apparently. I will be running 10-12psi daily with 16-18psi on scramble boost.

[NaughtyGT]

well then Gav,

It's RWC on Tuesday then,
$$$ together for the first mods:
a) source BPT pipe, VF10, Spaghetti Manifold, CS IC, then I'll relook @ it all again from there!

oh deah! Knew I'd be doing more than anticipated!

Oh yeah, I found set of nice 16" shoes from a Swift GTi in SA. They're being sent tomorrow so, the mods will be a little while ahead before I start. The wheels were needed for RWC next week so, they were the priority for now

[chicaboo]

There's no point getting the spaghetti manifold if you're doing a VJ14/VF10 hybrid. In that case you can just keep your stock manifold and keep all your heat shields. Remember to source the heatshield for the BPT dump if you get one. The spaghetti manifold is choice for a phat GT2560 or such. The BPT dump with VF10 hybrid is a cheap easy power upgrade. The spaghetti manifold on it's own will cost as much as all the other stuff combined. :eek: Fosgate can help source you a VF10, perhaps even prehybrided and ported.

Tar! Will get onto it soon as I get home this arvo, I'm off & Thanks again!

[chicaboo]

Gee, you're really keen! Lucky I haven't told you about the sik intake mods you can do with the JDM intake runners converted to a large side-feed plenum with upgraded TB, etc... :p

Gav.

[NaughtyGT]

you know, that's not playin' fair:eek:

[NaughtyGT]

Just noticed the BG GTR for sale in NSW gobsmacked:eek: gobsmacked:eek: gobsmacked:eek: gobsmacked:eek:
still gobsmacked:eek:
still gobsmacked:eek:
......it aint easin'!!!!!:(

[chicaboo]

I won't support you if you defile your car with a GTR motor... :mad: :p

Spank them with a B6T, it hurts them more!
Gav.

[project.r.racing]

and the rods don't bend as easy...

Gav.

no no no no......your worrying about nothing, I'll be doing the GT up. Just that those GTR's are friggin grunty & rare. I thought they were the bees knees of 323's?

[NaughtyGT]

and the rods don't bend as easy...

why do the tabloids rave bout' them as the 323 powerplant etc. One guy was trying to sell his recently, a black one for 5500, sounded bit dodgby though to me. He was bagging the B6T's. Real Salesman! Do you reckon the B6T's are better to mod?

[chicaboo]

Nah, BPTs and BPDs are better to mod all the way! But regardless, this is where I love to point out what motor is under the bonnet of the fastest Laser (call it a 323) in Australia. :D And it's a couple hundred CC less than either of the 2 motors I just mentioned :)

Gav.

EDIT: video attached. (http://www.youtube.com/watch?v=3dJqjYsVebw&feature=channel)

[NaughtyGT]

I suppose it comes down to asthetics then ey?, the later models do look groovy & definately more modern!

[chicaboo]

Yeah, but you have to put up with 4WD in the KF/KH/BG model turbos.
If it wasn't bleedingly obvious, that 10 second car has a B6T in it! :eek:

Gav.

[NaughtyGT]

Exact reason Gungadeer why I purchased mine! 2WD as apposed to the 4WD that was being offered, no comparison:p OK for rally use or if you live in Canada or Sweden etc where it snows, not road use though, nah!

The only thing I would do with a GTR would be to restore it, not use motor due to 4WD gearbox & $$$ & hassles that go with it! I wouldn't do an engine/harness swap, oh shizzie no:eek:

P.S. what a hero of ours with that Laser ey? yeeeeaaahhhh!

[NaughtyGT]

Gav,

Rocketman from 323 reckons the CorkSport will fit on OK so, if I use it on the VJ14, should be a simple option for now right?

For arguements sake though, if I am putting the hybrid on up ahead, would the BPT dump be the wisest move or will the CorkSport be OK when time comes for the swap?

[chicaboo]

You will always get more performance out of the split CS dump. But you will lose your AC for luxury of another 10whp or so. :( You need to make that decision yourself knowing the consequences.

Gav.

[NaughtyGT]

Thanks again Gav, decisions decisions! Also, I've been told the CS won't clear sump without mods, even a plate isn't enough + I will have to lose Air Con! True?

That would mean:
Mod CS
Remove A/Con

= pina already:o

Seems then that I really should get the BPT dump if I can find one!

[chicaboo]

Upgrade paths:

1. VJ14/VF10 hybrid with custom coolant lines, and BPT dump pipe. Option of presseing 2" s/s pipe into snout of compressor to reuse the stock J pipe and IC plumbing. I Suggest a small dual pass FMIC or CS SMIC with 2" s/s IC plumbing.

2. GT2560 with spaghetti or cast exhaust manifold and custom split dump pipe. Use with medium FMIC and 2.5" s/s IC plumbing.

3. GT2871 with spaghetti exhaust manifold and custom split dump pipe. Used with JDM intake runners and custom side-feed plenum and upgraded throttle body. Needs larger FMIC and full 2.5" s/s IC plumbing. I think is more for a serious engine build involving cams and stroke/overbore.

Gav.

[NaughtyGT]

hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm :rolleyes: :rolleyes: :rolleyes: either of the three will be an improvement!

I'll chew over what is feesable for now but doesn't constrict what I want to do up ahead. I'll probably do a bit to the little beasty, I just gotta get used to the old-school interior :rolleyes: then, I'll consider some serious mods :)

I'm pissed off so bad with Exhaust shop that butchered my cat-back piping. When installing pipe/muffler,hotdogs etc, he loosened the flange to the cat & so it leaks bad, he said it would settle in a few days, well, been over a week & it aint settling! Sounds **** & running real bad.

He won't be getting the front pipe job now, I'll be getting someone else :mad:

Should have my new wheels Mon or Tues @ latest. I'll put up a pic, so excited to find cool 16", one cool thing so far anyway:D
