How fast do you want to go? I can tell you how to pick up 8.5mph, and drop 1.4 tenths for hundreds less than a blower. Look at my mods:
edelbrock intake
65mm T-body
shorty headers
X pipe
stock flow tubes
2 chamber flowmasters
stock tail pipes
adjustable FPR
pulleys
K&N
advanced timing
HD clutch
3.73 gears
alum DS
and Nitto drag radials
Stock-heads, MAF, injectors, and fuel pump
I went from 15.2 at 90mph to 13.8's at 98.3-98.5mph. I know my cosuin's 100% stock 94GT coupe ran 14.8 at 93mph stock. Add to that what I gained and you're looking at 13.4 at 101.5mph.
Again this hypothetical, but I can attest to the fact that I've seen many 94-95 GT's with heads, intake, cam etc that only run 101-102mph in the 1/4. I've even seen two SC 94-95's at my track that struggle to run 101mph. Its all up to you though. On a side note, my cousin mentioned above with just gears, pulleys, and mufflers ran 14.2's at 97mph on street tires. He has just added a Kenne Bell blowzilla rated at 6lbs, and the car has no traction until 3rd, and even then it spins sometimes. With traction I firmly believe he is in the 12 second zone.
