blox throttle body question

[fictrs]

will a 70mm tb fit on a b18b2 intake manifold???? or will it hurt performance???

It will fit. But if you want to gain hp from that manifold you will need cams too...and a good 4-2-1 header will help even more so. i had to leave a comment since no one else did

U also have, no.. NEED to port match the the intake mani. Other wise ur still chocking it of power.. and i second wat redcivicls95 said

no you dont. it wont choke it of full perfomance, it will lack throttle response.

If thats the only mod you have its a complete waste of money

to upgrade the intake system, it needs to flow freely. this includes exhaust. by bolting that TB on you will only see minimal gains. very minimal. you would need to upgrade the intake, throttle body, intake manifold and exhaust for maximum gains. having a stock intake manifold is like taking a straw and pinching it a little. no matter how open the other ends are, there is still restriction. Hope that helps!

you dont "need" an intake manifold, but for MAXIMUM results, its suggested. I believe any ls manifold will fit. I don't think GSR IM's will fit
