Throttle bodies

I got a simple question, i have a 2003 gt u could say stock, only has intake, spacer and short throw shifter, i have the cat back exhaust and 3.73 gears but havent installed them yet. im lookin forward to buy a throttle body and plenum, should i go with the 70 mm or pay the extra 20 bucks and get the 75? i dont have any major plans for the car right now.

comeon... no ones got an answer to this? i thought this would be an easy question for u guys

ull probaly get around like 1 more hp. so its up to u if its worth $20 or not

70mm should be good for plenty of horse power and although some people would suggest that a 75mm is too big and would result in lower air speeds and lower torque i believe that is a lot of huey. 75 is kind of the industry standard especially if you plan on increasing your performance over the years with better manifolds and heads.

thanx a lot big dan! ur the man! haha yeah, thats what i had been imagining, that maybe 75 would be too big and actually harm my preformance. i dont get why they would even make 70mm, but oh well. thanx a lot for the info

yea u can get throttle bodies to big
