I have a 91 GT that i'min the process of building. It's goona haveTrick Flow intake, BBK 75mm TB, BBK CAI, Grantelli Mass Air Flow meter calibrated for 75mm, Full MSD ignition, BBK shorty headers, BBK H pipe with bullets and turndowns, E303 cam with stock heads andstock bottom end, C6 with a 2600 stall and a B&M shift kit, 4:10's, KYB struts all corners with stock springs and MT E/T streets. I was just wondering if you guys could maybe give me some numbers that i might be putting downand/or what to expect at the track with 150 wet shot and without the spray.

e cam is pretty sh*tty and with the stock heads dont expect your other mods to be worth much. your tb is way to big and your stall is too low. i wouldnt even bother with a new converter unless it was 3000rpm minimum. why the hell would you run a c6? you aremtn making jack for hp and the c6 weighs a ton. and i believe it wont fit in a fox without taking a big hammer to the tranny tunnel.

im going to say 230-240rwhp on motor. add 150hp to that on the spray

Wellthe c6 fits without a prob the only thing i had to do was shorten the drive shaft.

Ditch the 75mm TB for a 70. Your MAF needs to be calibrated for your specific injectors, not the TB. The MAF should be larger than the TB though. 76mm here.

use a c4... a c6 will suck power not as efficient as the c4i have a c6 behind my 429 fit right in no problemthey are just pigs though.

In my opinion(for what it is worth) most mods you would like to do are fine if you don't run stock heads. If new heads are out of the budget, maybe get the stockers worked over? Otherwise I think the mods are a mismatch to what the engine can use.....

what if i turbo it like a t76 because i have all that stuff and i also have a set of 30lb injectors and some people say that a e-303 cam is good for a turbo???????????

the ecam is ok for boost but there are many many cams that are much better. the intake and exhaust specs are the same on the ecam. boosted motors like a cam that has more lift and duration on the exhaust side. and if you go with boost, 30# injectors are too small

Why are u guys going for a c4 over a T5? Just because of the fact its more consistant? or ease of driving with an auto? My car has a c4 and im putting in a t5, just a 3 speed and 4.11's dont work for highway! I cant even get to the track( 30 mins away highway, to even test my mods) -Jon
