im fixin 2 buy a bbk or FRPP throttle body but i dont know whether to buy the 70 mm or the 75mm which one should i buy Im on the jegs website right now fixin to buy one
BUY THE 75 they both will bolt right up and the 75 may be more beneficial at a later time when you add more power. and usually they are about the same price.
you would only be talking an 1or 2 hp differance but 75 is way better when you do more air intake mods. the only differance is air velocity. the 70 has a higer velocity on a nearly stock car so the air mixes with the fuel in the cylinders better.
depending on your MAF , i would prolly go wit ha 70mm. you dont want ot have a bigget TB than your MAF, and if you go to bug (75 is for mostly stock) your guna kill the air velocity.
