I have a 94 GT coupe and i have intake, header, and Greddy exhaust system. What next? What will make the biggest diference i was thinking of injectors but im not sure what would you suggest?

injectors won't make any difference by themselves. even if you get bigger ones, the ECU is still telling the injectors to flow the stock amount. and besides, your car is already getting all the fuel it needs. why would you want to give it more fuel? it will just waste gas.

custom cams maybe? or an ecu upgrade. injectors wont do anything for an NA engine that is already getting all the fuel it needs.

an ecu defenetly

I have a 94gt and i was curious to which header you have and where you bought it from because i cant seem to find any.

I have the same on my 99 GT.

I was thinking about a UR pulley this summer.
would that make a big difference with the CAI, Header and exhaust??

it would add to the hp but not sure if it wold ad more due to your mods.

I do not think so. But will have a 3-8% gain in hp.

your next step should be a Adjustable fuel regulator with A/F ratio meter or a fuel computer like the Apexi SAFC.

My header i had shipped from Japan ill find comany name and post it when i get a chance? How hard is it to turbo a 5sfe does anyone have a parts list or want to sell the set up off there 5sfe. How hard is this too do and how expensive? I wanna buy one off someone because i am not good and collecting parts so if anyone has parts please tell me. If igot a turbo i would also sell my header too.

Anyone know when they are making the 7afe header from Arospeed, i heard it wasn't going to be in production for a little while?

You need:

ct26 turbo from a mr2 or all trac/gt-4
3sgte oil pan and oil return lines or tap your own pan.
3sgte down pipe (aftermarket or stock)
3sgte turbo elbow
7mge injectors or upgraded 5sfe ones
3sgte MAP sensor
intercooler pipeing
mk3 supra intercooler makes for a good front mount
metal head gasket from a 98+ camery
3sgte exhaust manifold
BOV
boost controller
MSD BTM (your motor will detonate after timeit you dont use this or a stand alone to control your timing)

Thats basiclyit as far as what you NEED but you can of corse get more toys to go along with it. For example i have a TT, MSD 6a, Supra tt fuel pump and will be getting some gauges. I think thats it but I am tired so i may have missed something, if so I'll get it in the morning.
