I have a 96 GT, and I'm looking into throttle bodies. Should I get a 70, 75, or 78mm unit? Which is a better match for the motor?

honestly its which one you like best, they will all do about the same thing. i went 70 myself

My brother installed the one piece 78mm BBK TB/plenum. It looked good and performed very well.

most ppl say stick with the 70 for NA. theres actually a dyno test done in the sticky where someone lost peak horsepower (but did gain maybe 5 through most of the RPM band) with a 75mm tb/plenum so its nothing to cry about. cant remember how the 70mm stacked up tho. may as well just go with the 75 or the bbk incase you run FI down the road.

i have no complaints with my 78mm but alot of ppl will argue this until the world ends
