View Full Version : Engine transplant from 1.5L to 1.8L Turbo'd

I've gone through what I could find on engine transplants on the forum and found different parts of interresting stuff.

Threads like this, but this is a thread about the V6: http://www.astinagt.com/forum/viewtopic.php?t=614&postdays=0&postorder=asc&start=0

In another thread I found that the turbo'd engine usually used is: JAP-SPEC Familiar GTX 1.8Turbo

Is this what I should go for, and where can I possibly get this engine (I'm located in Norway). Should I talk with a Mazda dealer, or?

My F is a 1996 modell, 323F i GLX Special Edition 1.5L, so far I've only done a few mods: Jamex Sport Springs (40mm) and K&N Air Filter mainly. The next thing I'm doing in a few days is new shockers, I just need to figure out what to get!

More details on my car and planned mods:

Thanks for any response,

First: Welcome! Hope you find what you're looking for here.

Second: Nice work on the engine bay. Looks sweet as.

As for sourcing a GTX motor, the other guys who have gone turbo should be able to provide a better answer than I can.

Welcome to AstinaGT, enjoy your stay.

In Australia we are lucky to have many companies who import Japaneese engines and parts.
www.adelaidejap.com.au
www.ekw.com.au
and many others. They are one source of engines, the Australian Ford Capri uses the Mazda BP 1.8 and 1.8 turbo engines (I don't know if they made it to Norway).

Some interesting B5 to BP conversions can be found on www.fordfestiva.com

Wow, thanks for all the great comments :)
I started hanging on the Holland 323F board a few months ago, but that one is no near close to having the activity here! There are some nice folks there to though!

I don't have any pics of my engine bay, so sorry, not even the red one is mine. The idea is to get the Blue EcoTec valve and spray-paint the engine's lock in the same color as that!

From www.adelaidejap.com.au:
"International air or sea freight can
be arranged prior to shipping.
e.g. USA West Coast minimum 1Mcube is $500"

If the freight from Australia is somewhat around $500 (hm, USD?) it could be quite manageable.

From www.ekw.com.au:
"BP-T : 1.8 Ltr DOHC Rwd Turbocharged 117 kw suit 323/Laser $1595."

But what about the "JAP-SPEC Familiar GTX 1.8Turbo"?

I recon I'll use around $5000 on the car in september/october, the idea was to fit a new set of wheels to but by that time to, but maybe I'll skip that until next year as it's so late in the season. My current setup is though REALLY good on the road, sticks like glue and gives a smooth ride.

Anyone here fitted the whiteline-equipment? (Can't find the URL again) Right now the car handles to bad in turns, I need it a lot stiffer :)

I'll look into the Ford Capri now!


Thanks all,
Sondre

Firstly welcome Care Bear!

Secondly I am no expert, but you have come to the right place, this place is full of em.

Thirdly, I did the whiteline swaybar only so far, and I found a HUGE difference in the way the car handles into and out of corners. No more understeer for this little Kitty! And it's cheap, oops, I mean a bargain for instant obvious change in handling. I can't comment on anything other than that, because I haven't got that far.

anyway, good luck, take lots of pictures of everything you do to your car, and let us know everything!!!!!

cheers!

From www.jaustech.com.au/engines%20-%20mazda.htm:

BP TURBO 1839.6 GTR TYPE 230 $4,500 Now In Stock
BP TURBO 1839.6 GTX TYPE 185 $1,600 $2,200
(Australian Dollar)

From www.adelaidejap.com.au:
BP Turbo - 1839cc DOHC 16 Valve, 4 Cylinder, 4WD, 180 Hp for GTX, and 235Hp for GTR
GTX Engine only Special as per picture $950
GTX Engine Package, no box $2,200
4WD GTX Gearbox $1,250 Exchange
GTR Engine POA (very hard to get)

I figure this is also Australian dollars? As the package price is exactly the same from both of them?

the BPT GTX here is the same as "JAP-SPEC Familiar GTX 1.8Turbo" right? Should be :)

The Norwegian Krone (our currency) is really strong nowadays, so I'll save a whole bunch of money getting the engine from outside the country.

The GTR seems like a sick (230bp) upgrade if it fits in the BA model, but seems a little costly compared to the GTX. Does the BPD engine fit in the BA?


So now I'm pretty sure what type of engine I'm looking for (BPT-GTX), but what about package or just engine? What other equipment do I need to get? There ain't no problems with FWD vs 4WD?


When I come to think about it, my neighbour has two GT-R/GT-X (not sure which they have, but father and son have the same car). Well, the son in the house is currently doing a complete renewal of his GT-R, he is doing a whole new custom styling which will blow your minds, it will look soo cool! I'm sure I'll get you guys a picture sooner or later!

But as it seems, it's engine from those "boxed" 323's that fits in my 323F (BA)? Hm, I guess I could go and have a chat with this guy and see if he could give me any advices on how to get an engine, or possibly import together with me.

From www.corksport.com:

------------------
1.8L T4cyl (BPturbo) w/approx 180 HP 90-94 Protege
90-95 Escort GT
86-94 323 ##
95-98 Protege ##
92+ Mx3 ##
## installation can be difficult and expensive. (wiring/ECU, mounts, tranny) $1099
------------------
1.8L T4cyl (BPturbo) w/approx 210 HP (from GTR)
These engines are difficult to locate. Delivery time may be extended.
Same as BPturbo above $1875
------------------

This is American dollar I guess, BPT-GTX & BPT-GTR I presume?

The Australian sites quote Austrailian dolars. Check www.xe.com for conversions.
To convert to a BP or BPD you will need a BP or B6 transmission. I can't say that they are the strongest.

Just letting you guys know I've recently updated my car site, made it into multiple pages now.

http://fanms.com/car.aspx

There's also a new pic of my engine bay (removed the red pic):

Question: What type of engine does the 1.8L has? If I get a 1.8L BA, is it worth dropping the whole engine for a BPT, or is a Turbo add-on for the existing engine good enough?

Anyone have a good URL to a site that explains everything about the car? I want to do a full tuning of everything from breaks, exhaust, engine, tinted windows, full-body styling, lowering, sport-shocks, bucket seats (4, forward & back), whiteline bars, NOS, direct air induction and more!

Thats a good general reference on mazda 4 cyl motors and what "bits" can be interchanged between the different models

There is no one webpage that explains all about the 323F/Lantis/Astina
as they aren't modified that much. Also I know 4 guys that have turbo'd
a BA and not one of them is the same as the other as each one of us has
different ideas on how far we want to go. There is no single answer.
How much do you know about cars. You mention NOS. Is it legal in
Norway. Is it for street or for Drags. I usually hear NOS being mentioned
by people who have watched Fast and Furious and know very little about
cars. If you do know how it works then you would know that the GTX
only has cast pistons and the injectors would not be big enough so you
may as well rebuild your N/A motor and use the money saved to buy
better components.

Be clear what you want to do and we can then answer your questions
better.

The Australian 1.8L have a little more hp than the one we have here in Scandinavia, and that's the reason why you guys have rear disc-breaks.

I read through the MX5-engine page but I diden't figure out much about the standard 1.8L engine that is in 323F BA?

Mal, you mention that a few people have turbo'd their BAs, are we talking a turbo-upgrade here, or engine transplant?

Mal, I guess reading Revs & Max Power could be compared to watching The Fast & The Furious, hehe. Well, I just listed up a little list of stuff I'd like to do for the fun of it, if it turns out not being doable I'll survive :)

I diden't get a clear answer to my main question, which is whatever the NA engine in the 1.8L BA is fine enough for tuning with a turbo and as you mention, rebuilding and fitting new components?

I talked with a guy yesterday, his friend smashed a 323 which is condemned now. So I might be able to buy his BPT-GTX and gearbox at a nice price.

Get the GTX motor its the most cost effective way of doing the job.
The standard NA motor is a BP-05 and the GTX is a BP-26. Same
motor but the GTX has different heads, pistons, injectors, intake
all for use with a turbo so get that. All the BA turbo conversions have
been done by using the GTX motor as its the cheapest way to do it.

I have been trying to stress "Plan a build and then build to your plan"
otherwise you will end up buying parts that are not the best marriage
and performance will suffer. If you manage to fit a GTX gearbox in
there let me know as I thought it not possible without major work.

yes! buy his GTX (BPT) engine. Is this 323 GTX a front wheel drive of 4wd version? as if it's FWD, then get the gearbox, otherwise you might have to source one from a wrecker.

you could turbocharge the NA 1.8 (BP) but you couldb't run much boost into it reliably, as the compression that at runs is too high. you *could* rebuild the NA engine with lower compresdsion, but it would be cheaper to install the BPT in your car, as a set of fiorged psitons are about $1200 AUD.

And all turbo talk in here relates to first doing the turbo conversion (as it's the most cost effective :)

i think i've covered most of what you asked!

As far as I know all the GTX's are 4wd. The 2wd's were Infini's or GT's
etc.

I decided to keep my existing 1.5L and just pay up whatever cost there will be in taxes for the transplant. But now the question is if the 1.5L gearbox is similar or at least mostly similar to the 1.8L, do I have to get a 1.8 gearbox when I insert the BPT-GTX engine? Hm.. does the engine include IC?

Shopping list: GTX-engine, ECU, AFM, coil and uprated clutch.

The motor doesn't include a Intercooler. The intercooler on a GTX
sits in the bottom corner of the inner guard underneather the AFM
but not at all connected to the AFM. The stock IC on a GTX is very
small and only good for stock boost of 7psi. If you want to run more
boost then you will need a better aftermarket IC to be front mounted.
Best ask you local mazda dealer if the 1.5 and 1.8 gearboxes are
interchangable as never seen a 1.5 over here.

Hey CareBear,

Have you tried the UK importers of used Japanese vehicles and spares? That might be worth a try, they may be able to source a GTX motor so you can get one a bit closer to home.
