Ok I'm going for either a t3/t4 hybrid or a t28, if i go hybrid im gonna buy the enjuku stock location manifold, if i go t28 im gonna keep the stock manifold for now. what else is needed so i can order everything. I'm gonna run stock boost until i can find a cheap intercooler, reccomend anything? thanks.

Its sounds like your saying you will run a T3/T4 on a stock intercooler. I would spend your cash to get an upgraded intercooler before you get a bigger turbo. If you get a bigger turbo make sure you get injectors and a fuel pump. Also an upgraded MAFS. Also a few tuning devices like a SAFC or have your ecu tuned.

wouldnt it be ok to run a hybrid at stock boost on a stock intercooler? I have a walbro 255 do i need injectors to run stock boost? or a MAFS? I'm only looking into getting a turbo because mine is on its way out (leaking oil and making a horrible screechy sound) i am not looking for insane power, but if im getting a new turbo might as well have the potential.

Well in that case. It sounds like if you keep it at stock boost it would work ok. I have never seen a stock SR SMIC I got my Greddy FMIC because I got a motor set instead of a front clip. No SMIC. I just have heard how small it is and that is where I am questionable. But if you run at stock boost then a hybrid may be ok. A S15 T28 would be fine, I do know that. But still I would get some injectors because the SR fuel system reaches its max pretty quick even with a Walbro.

I agree got_Boost - peope around here are just itching to flame somebody. That being said, I am pretty sure it is Super Air Flow Controller.

Goat - I would suggest an Isuzu NPR IC over a Starion. I did some research before i bought mine and there was a general consensus that the NPR is better than the Starion.

hey all, im not trying to be picky, but i belive SAFC, from Apex'i, stands for Super Air Fuel Controller. Here is the product description from Apex'i's web site.

"The second-generation S-AFC is a fuel computer that adjusts fuel/air ratio by modifying the air-flow meter/MAP sensor signal. The S-AFC features a user-definable, eight-point, adjustable fuel curve that can be set in 500 RPM increments. The range of fuel adjustment is +/- 50% at each of the user-defined setting points. On hot-wire vehicles, the Deceleration Air Flow Correction function is capable of curing the erratic idle and stall problems associated with open-atmosphere blow-off valves on hot-wire air-flow meter systems. The S-AFC is capable of monitoring and replaying the following data channels in Numerical, Analog Meter and Graph displays: Intake Manifold Vacuum/Boost Pressure, Air Flow Capacity, Intake Manifold Pressure, Karmann Frequency, Engine RPM, Throttle Position, and Air Flow Correction "

What all the tech, mumbo jumbo means, is that, it piggy backs off of the stock ecu. It takes the MAF signal, that the ecu uses to control the amount of fuel going to the engine, and changes the voltage (the ECU no longer see's the MAF signal, it now only see's the SAFC's signal). The SAFC, by doing this, allows the ecu to increase the amount of time that the injectors are open, also know as duty cycle; thereby increasing the amount of fuel going in to the engine at a given rpm.

You need this to decrease the chances of detonation at higher boost levels. The reason you usually upgrade the stock injectors at the same time is that the SAFC can push the injectors to their max 100% duty cycle. at which time you will be getting no additional fuel. And with additional boost, no fuel is a detonating experience"

I'd recommend you do it hte right way, but the truth hurts sometimes, and i dont want to offend you.

None of that is a good idea...

if you want a big28, then go ahead, but there is no reason you should be considering even doing that without larger fuel injectors, larger intercooler, larger exhaust piping, larger fuel pump, and some sort of fuel/engine management or a tuned ecu..

the t3/t4 idea is even worse on a stock setup..

Hey, do it right, or do it twice, ya know?

I can't tell you how many times people rush into things then regret it later when they have to do everything again, and spend twice the money, you are much much much better off diong the things to the car that will let it accept a t3/t4 before just bolting on a turbo then trying to do the things to make it work....there are so many miscellaneous cost that people dont even consider, dont rush into anything is my advice.

also: "No matter how hot she is, someone is sick of her ****"

: )

hope you dont take offense to my suggestions : )

you're right im gonna just save up and buy a FMIC and some injectors, i have a full 3" exaust and a walbro. do i really need a engine management system for a t3/t4 or a big 28?

you dont need a standalone, but you'll need either an Apexi SAFC or a tuned ecu (jwt) or greddy emanagment or something....

Not to be picky, but S-AFC actually stands for Super Air Flow Converter.We just installed one on my friends TII. ;)
