Just a quick question, I am lookin into upgradin my throttle body, and I notice how there is a bunch of diffrent sizes, 65mm, 70mm, 75mm, is there any issuses with a b16a2 motor with to much flow, or anything else that I should be concerned with when changin the body?
thanks

you need to port match the intake manifold to match the throttle body opening. im not sure how much it can be made bigger and i dont think it can have to much air. i mean turbo's force air in the cylinder so i cant imagine having too much air.

leave it stock unless you have a modded engine.

alright, yea that makes sense

you probably won't be able to go much larger than 64-65mm without running into the iacv passage on the manifold when port matching it and even at that size the gasket sealing it will be very thin in that area.
