a 75 might be too big...u dont really have a lot of mods..

i went with a 75mm on my 97 cause i did the headswap and a lot more..

with my 00GT now i went with a 70MM...works jus fine..

a lot of n/a GTs use 70..and when they go blown they go to 75mm

I agree with Red00GT. The 70mm for an N/A car and the 75mm for a forced induction car. On an N/A car, I see that it's pointless to get an 75mm car because there is really no gain. But, they should both work fine. If you plan on boosting soon, go with the 75mm.

Yep, 70mm for a car with a few bolt-ons. 75mm with internal work or forced induction. Reason is, the 75mm will slow the air velocity entering the intake. You'll gain more at the VERY TOP end (5800-6200) but you'll lose too much low end torque due to the decreased air velocity.
