I was jus wondering what the diameter of the manifold is. do i jus use my stock throttle body or do i need to bore it out or do i maybe need a b16 or b18 tb. Any help would be great, thanx.

 

The openeing is 62mm, stock t/b is 56mm.I just bought a 62mm from BBK.

 

how much did that run u? wouldn't it be cheaper to jus get a gsr TB since they're already and bore it out?

 

yea its cheaper to get a b series tb. look into an h22 tb from obd1( for ease of sensor matchin), which should bolt up. im pretty sure its a 62 mm, as opposed to the 60 for most b series and the puny 56 that the stock d16 one is.

 

wheres the best place to find a b series or h22 tb? classifieds? Also a type r cai with bolt rite up to this setup rite?
