What size throttle body?

[SupersonicGSR99]

os so my butterfly has been sticking on my stock throttle body and im boosting my car in the next few weeks anyways so a new throttle body wouldnt hurt. should i get the 65mm? and which is better skunk 2 or edelbrock?

68

 

[rwlsvtec_03]

skunk2 TB is pain on the rear end when you're working on it, love my eldelbrock!

 

[SupersonicGSR99]

ya so ive decided im gonna go with an edelbrock 65mm, good? also venom intake manifold any good to go along with that? i love the looks and is a direct bolt on?

 

[Samurai_Blue]

65 is too small....67 is stock itr sized....go 68mm as i suggested you will be doing yourself and your motor a favor

 

[eg6ie]

gotta match the im.

 

[Vtec-Pwr]

go with at least 68mm or 70mm, port match with the IM.

stock ITR is 62mm, not 67.

What ever size you get make sure you port match it or its useless.

 

[wite2nr]

70mm and port match

depending on your build and how crazy it is, if its just a bolt on kit on a stock motor then a 68-70 will be fine, just like they said make sure u port match the intake manifold, i dont think there is a need for a venom intake manifold, a skunk or blox will be fine.

what is the rest of your build?

 

[Spody02]

you dont need to port match, you ever heard of tapering

could be good if you know what size your i/m inlet is
