s-afc in a BJ
 

hey guys
i was just wondering if anyone has heard much about instaling an s-afc in a bj astina?
what kinda gains can be had?
someone on fl.com is going to be putting one into his kq laser, an i was just curious if they are worthwile installing?
are they very expensive?
thanks

hmm.. unless you got a hairdryer under that bonnet, not a terrible lot I dare
say. You'd probably have to work it in with an after market ECU, exhaust and
intake setup at least for an NA.

looking at about AU$620+

Apexi SAFC Neo

im the one installing the SAFC, and im doing it cause ive done a few mods to my car, its still NA, but the SAFC will help improve things the standard ECU cant.

Have done.

12thou over bore,
lightend crank
aftermarket cams
aftermarket pistons
tuned length mandrel bent extractors
mandrel bent exhaust
port and polish
lightend fly wheel
HD clutch
Custom CAI ( in progress )

so after thses mods, and the engine has been run in, ill be doing a dyno tune, and i will make much more from teh engine using a SAFC then without it, and means i dont have to buy an aftermarket ECU yet, until i decide if im going to get really serious with it

Also im getting the SAFCII, not the SAFC NEO, and i got mine for 185, plus postage

problem with something that hasnt been tried - it hasnt been tried. if you've spent that much on your engine ghost (and welcome here), why skimp on the brains of it?

so if i only have a k&n filter, a 2 1/4 in exhaust and high flow cat, it wouldnt be worth gettin one?
what is the next step for performance?

because if i dont need a whole new computer, would be over kill i think, especially for the time being, would rather get somethign that will allow my car to run well, then get something which will allow my car to run properly, and cost a shed load more. but im still looking into the options atm.

KQ, the S-AFC may make your car run better, may not, cause there arent any real changes to your engine, if you wanted to start upgrading, you really need to look at your budget and what you want to achieve, there are alot of turbo kits, cold air intakes, cams, options galore really, but you need to weigh your options, and work it whats best for you.

turbo kits = big $$$
i just want some good "bang for my buck" mods.
price doesnt matter too much really, coz if its worthit ill save up for it.

well then go the turbo kit lol, looked at one for a good price, havent contacted them yet, but

http://www.turbo-kits.com/protege_turbo_kits.html

have a looksie

maybe look at a CAI, not jsut a pod filter, then bigger injectors, aftermarket cams, the mods you can do are only limited by your pocket, and how far you want to go

that kits for a 2.0lt. :-(

same engine as our, its just the 2litre has a stroke kit on it. Ask for information, the kit will fit.

even onto my 1.6?

oh yeah, lol, sorry forgot yours was the 1.6ltr, mines the 1.8ltr find your engine type, and look around, maybe your first upgrade shoudl be to a 1.8, or even to a turbo engine, you will always be limited by your engine type.

i dunnnooo....
my boss at work keeps tellin me to go to willall racing and get them to do some work on it.
but i dunno what way to take it.
id love a nice shiny set of quad throttle bodies though!!

go in and ask what they would resomend, cant hurt

mate its a 1.6L. doesnt matter what you do you'll always be limited by the small range of mods and performance available from an engine thats got 20% less capacity to stuff fuel/air into and a smaller modding community.

i'd suggest the 2.0L engine if you're upgrading, no point going the 1.8L if you're looking for more power in the future

KQ - converting to either a 1.8 or 2L is a big task, and its not just drop in and drive away, you have a ****e load of stuff to make the task worthwhile, and honestly could see such a task be upwards of $5000, even more if your going down the F/I route (figure in about another $10000 to turbo), so thats 15k just to drop in another engine and turbo, my opinion would be to sell your car and find a laser or astina with the 1.8 or 2L already in place, and then go from there...

Whole new computer which has been done before, and is essentially a weekend job to install (by the way, the stock ecu stays, microtech/haltech/whatever runs in parallel, stock ecu controls a bunch of stuff like tacho, VICS and so forth) isn't overkill.... not when compared with something that has never been tried and you can potentially spend weeks off the road chasing gremlins.

Piggy back isn't really a half way point between nothing and stand alone, its an alternative to stand alone. You will yield the same outright power gains (assuming the stand alone kills rev cut and lets you get the engine spinning faster than it probably shsould) - and close to identical fuel economy, no matter what system you chose to buy, the difference is really only in "nice to have" features.

the stand alones that are proven on our motors are very quick and easy to install.... but you only have to look at the grief the guys in america have had trying to get stand alones to operate..... problems with stock ecu's "working around" the piggy back, problems with open and closed loop operation... plethora of voltage clamps and other hacks that are needed to get the things working properly.... its kind of nightmarish....

I understand that piggy backs are cheaper and more attractive because of the cost, but its a bit of false economy, especially when you factor in the cost of all the stuffing around you'll have due to the "never been done before" factor...

its not feasable for me to sell my current car at the moment, because of all the stuff that is done too it, and the stuff have allready bought and ordered...
it would be more different to do a 1.6 i gues.... thats one positive! lol
i dunno.. has anyone ever looked into engine conversions? sr? ca?

If your looking at conversions, its best to look abroad and head on over to www.mazdas247.com and look at what the US boys are doing. Lordworm is a mod of NA tech over there and when I was last on there (2months), some blokes were interested in puting a KL-ZE V6 into the engine bay!!

Lordworm Help us out with a reply!!!

ok,
KLZE APPARENTLY fits with the 2L engine mounts. Its been done by a few canadians - but the language barrier (french ... obviously...) has meant that finding out the ins and outs are a little difficult. THat and the people who have done it are not active members mazdas247 means its hard to get solid answers.

However, assuming for a second that the mounts do bolt straight up and it is a 100% straight drop in, you are going to need radiator, relocation of the battery to the boot (neither of which are a big deal)...and... a new tacho, or some way of getting an RPM signal to the stock tach. Stock tach reads off the ecu which reads off of the crank and cam angle sensors which are different in the KL. You would also need to run both the existing ecu and the KLZE ecu (or a suitable stand alone) side by side, so that the rest of your dash operates as required.


its certainly possible, and would yield some pretty good results (2.5L, high revving V6 vs economical mild mannered 1.6L)..... KL also has plenty of big time upgrade potential...just look at what some of the probe guys have done.

KL also offers big potential for monster power should you chose to go to forced induction.

Not a conversion for the feint hearted... but if you have the patience to deal with the problems you will no doubt encounter, and have plenty of cash to see it through, it could be very rewarding.

Otherwise there are turbo kits available for the 1.6.

going to a foreign engine means custom engine mounts, and loads of other customisations, and the problems of compliance to boot....but if you heart is set on putting something non-mazda under the bonnet, check out the mitsubishi 4G63 turbo (something from a VR4 gallant preferably) - they are tough as nails and capable of pushing out copious amounts of horsepower on stock internals.....plus rediculous amounts of aftermarket support to boot.
