i was wondering what size a stock throttle body was on a d16y7 and if i put a 70mm throttle body on what i would have to do to my intake to make it fit.

thanks

if you put a bigger throttle body on, you have to bore out the intake manifold to match the size of the throttle body. 70mm is a bit extreme. i would suggest the 62mm from the b18c5 (integra type R) and port match your intake manifold.
to make the intake match up, you will need some rubber connectors (assuming it is aftermarket intake like short ram or cold air)

called hose coupling

what do you plan on doing?? is the TB just do get more air into the engine?? it doesnt add all that much power.

i am planning on putting a SKUNK2 pro series intake manifold and throttle body-68mm so the intake manifold would match the throttle body.

you said the 70mm is a little extreme. would it be bad if i put a 68 or 70mm tb on?

i didnt say it would be bad just extreme unless you are looking at 400 whp anytime soon.

as long as the intake manifold is prot matched with the throttle body you will be good
