I have a GSR throttle body bored out to 64mm. Which throttle body gasket should I get when I replace my GSR intake manifold with a Skunk2 intake manifold, OEM GSR or OEM ITR?

 

i don't know of any 64mm gasket you can buy that fits the Skunk2 (or ITR or GSR) intake manifold. stock the GSR is 60mm and the ITR is 62mm. what you may have to end up doing is what i had done: you or the shop must carefully enlarge the hole (with scissors). of course i would start with a brand new one (might as well). but that was a long time ago...
what about the people making larger than 64, maybe they have something: BBK, Spoon

I would go with the itr manifold gasket. Since your throttle body is ported, you might need to cut part of the gasket to fit the 64mm throtle body. A stock itr throtle body is 62 I believe.
