Like everyone already said, You aren't gonna get a NA Z anywhere near 12's or even 13's. I had a 93' NA with Intake, Exhaust, JWT ECU and could barely break into 14's. The Z is not a drag strip car. It is a touring/autocross car. The TT would even be hard to get into the 11's - You have major wheelhop issues and it will cost a lot of $$ to get it to even 400whp. I had a 94 TT as well and I dropped 6 grand into it and it made 410whp. The Z is also heavy, I was in the low-mid 13's with my TT Z. I sold it and got a car made for the drag strip..
