is it possible? what throttle body gasket do i run?

 

all B,D,H-series throttle bodies are interchangeable i am pretty sure

 

It is possible, I just finished swapping my y7 intake manifold for an y8 manifold make sure you use the y7 throttle body gasket if not you'll have a nasty vac leak.

 

i used the y8 TB gasket on my y8 mani with y7 TB with no problems at all, y7 and y8 TB gaskets looked identical. anyways, to make the y7 TB work you're gonna have to get the throttle rotor from a z6/y8/ls TB because the y7 rotor will not function properly due to it's new location on the y8 mani.
