i've been tryin to find out what size throttle body to put on the sk2 itkm i have for my h22a4, so it fits right on the manifold, and sizes up with my intake, can someone help? I can't find the answer, and limited on time.

 

couldnt you just buy a throttly body and then have your i.m bored out to adapt it

 

Probably cheaper to do it that way as well.

Also unless you running a turbo, bigger isnt always better with throttle bodies. N/A motors function better on less volume intakes vs bigger intake volumes.

There are always exceptions to this rule, but for the most part on stock motors, bigger doesnt mean better

 

Go with a 68mm its more then enough for an N/A car and will fit fine. Plus if you try to go with a 70 or bigger there is huge price difference. I picked up a 68mm that I plan to install soon and the shop told me this would be my best choice because my motor is N/A. As far as fitment getting a skunk2 tb would proble be the best fit since its goin on sk2 IM.

 

Sounds good, thanks for the help!
