What T/B to run on an ITR Intake manifold on a 85MM B18C1 with B16A head . NA motor , used for track racing ?

 

70

 

depends on how much air can you flow...

 

I'd run the 70, and have the intake manifold port matched to the head and the throttle body. Doing this could be good for as much as 8 to 10 horses at the wheels depending upon other factors.

ive done that.. currently sitting at 200whp with stock b16a revlimit.. cant say if it help but i expected a lil more..btw using an str 70 mm throttle body.. basic ls/vtec setup with usdm itr pistons with skunk stage 2 cams

 

i want to know how you port the intake manifold to accept the 70 mm tb - it looks to be about 68 before you "chew" into the water line up in the corner....
