you can use the stock se injectors in the 2ndary position as well or spend 200 bucks and get 2 1600 cc injectors, going lean will not be a problem caused by fuel injector capacity.
the stock ecu is very forgiving. it doesnt really care about much beyond its narrowly defied parameters.

its fast, its cheep and it looks clean, nearly stock.
if you read the links i posted you could even use the stock intake manifolds and just weld on injector bungs like mentioned earlier and your car would probably look smog legal enough to pass in most places.

FB II

if your going to go through the effort of buying, installing and tuning a haltech system doing it on a NA 20 year old engine would be a waste of money, not cost effective at all.

 

so what are some types of fuel controllers available?

is the F5 still available?

 

oh daaaamn, i didn't know an AIC was a "bolt-on and go" affair.

you still gotta BUY, INSTALL, FABRICATE/WELD, TUNE on that same 20 year old car. you make it sound like it's gonna blow up regardless, so why wouldn't you want something that could easily work on the next motor whether it's the same or a TII/RE/REW/ etc...

i honestly don't care, i'm a carb guy. but if i was going to go thru "any hassle" i would go all out. an aic setup does work beautifully, but they're not all that cheap. unless you get a nice deal on a used one and most you still have to tune with a pc. why not step up a bit and get an e6k?

and the ones that dont need a pc to be tuned have their own special controller unit, which isn't that cheap...

here's an example: http://www.autocarparts.com/part/list/325/

i just think if you going to spend a decent amount of money, it's not much more for a full stand alone. a little more tuning but damn it can be worth it as Alex well knows.


or hell, just get a haltec/ microtech FUEL ONLY computer. run all injectors on one setup. probably costs the same and you could tune for better fuel mileage and more power

 

the f5 is not available anymore.
you can find one for around 300 used.
hks and apexi make them. you can get older models for 100-200 dollars.

some AIC systems come a pipe that has in injector bung. It hooks in between of the throttle body and boost piple. its bolt on.
I suggest you look on ebay and the parts trader.

the AIC's are tuned buy a few bottons on them normally, they are not really an advanced electronic device.

 

Megasquirt? maybe that would be a good route.

Here is the big question dsm.who, What else has benn done to the car? is it completely stock?

 

Do you think think Alex went the cheap way? He has spent plenty of money, and has one of the best Haltech tunners around!!!!!!.

I went the cheap way and the fun lasted about 1 year.



I had to learn the hard way, so don't make the same mistake. Do it right the first time!!

For anyone planning on a 4 injector turbo setup.......running 550cc primary and GSL-SE 680cc secondaries is a great setup for about 12-13psi on a stockport engine.My old junkyard S4 engine w/S5 turbo loved this amount of fuel with no changes to stock S4 ECU pulsewidths, and would pull cleanly at any speed or throttle settings.Pushed me to many 13.5 quarter mile runs before the tired old motor lost a water seal and had to be retired.
Now, Im running 800cc secondaries and pushing up to 14psi on the fresh S5 engine with stock S5 ECU.Its a little on the rich side,especially if I go high RPM with medium throttle,but its hardly noticable and only sputters for an instant until I shift, or just floor it to spool the turbo.The S5 ECU is pretty good about keeping the secondaries offline at higher RPMs,unless theres some manifold pressure present.Its totally streetable.
Big ol' 1600cc secondaries are cheap and plentiful,but there are enormously too big for most street machines and youll definately need an aftermarket ECU or fuel controller to crank them down.

And for the record,tearing all the needed wiring from the FC dash harness is a waste of time.Its much easier to fabricate the left side harness from scratch using the FSM.You can de-pin many of the wires on the left side ECU gang plug since lots of the wires arent needed on the FB chassis....AC relay,PS relay,milage sensors,shift up light,blower relay,ect....the remaining wires needed for engine operation arent numerous.
On S4 engines youll need to lay about 15 wires to power the ECU,fuel pump,CAS,coils and circuit opening relay.For S5, its even less since the CAS runs through the rightside harness.
And theres no need at all to cut into the FB's wiring harness.Nothing for running the TII engine will need to be spliced to the recieving car.Just be sure to install an FC main fuse box under the hood to simplify powering the TII ECU.Its an easy mod that youll be glad you did because it also deletes the crummy 1st gen fusible links.Dont be scared about TII wiring....its CAKE if you use the FSM and are comfortable with a soldering iron.

its not cheap, its not easy

 

if you know, and search its not hard. ive been researching this for about a year and a half now, and people will be happy to answer your question, if you have a specific question.

not so happy to answer though, if you ask really broad questions that have been covered.

 

Exactly!

 

yes its completely stock.
i understand there are numerous mods that need to be done prior to turbo-charging the vehicle. i am a noobie to turbo FB, but not a noobie to rotaries.
i am basically deciding if i want to keep this SE stock or make it turbo. i know the value is greater keeping it stock as opposed to having a header, exhaust, no emissions stuff, etc. however i badly want a turbo SE.

 

I guess it depends on how much you want to spend, if this is your daily driver and what is the intent of the car. Having a nice stock SE is really cool, but a turbo FB is like finding Atlantis every time you get behind the wheel..........and it starts.

 

OK OK OK OK OK

I stopped reading this thread half way through becuase I kept seeing

buy a TII clip - use a TII computer.....thats one way


I have helped build a GSL - SE with Stuart Hoo from Can-Jam
We turboed the SE motor with an S4 turbo and manifold
!!!Used the SE computer!!!!
SDS fuel Man. with 2 extra injectors welded bungs to the UIM
and aquamist instead of an I/C

the cheapest and easiest way would be swapping TII manifolds and using the TMIC (custom hood scoop too)

but the bottom line is he doesn't need to buy a TII parts car to make this work

 

true... and that was stated in here.. but you only read half way thru

that way would be the way i would do it honestly. use an s4 intake/ tb and fab up the turbo and everything else. sds digital would work great, but so would microtech/haltech/and even megasquirt.

i've actually been wanting to learn more about the sds digital setups

 

honestly i wouldnt have much of a problem going with a standalone
my problem is finding someone to tune it
need someone near philly and that is knowledgable and trustworthy.
any suggestions?
