i dont know if this sounds stupid or not but i could not for the life of me fine a performance throttle body for the g37 coupe i looked everywhere and nothings come up. is there one made yet and how much is it? would it be worth getting?

 

I haven't seen any aftermarket TBs for the VQ37. You could always go the custom route and bore out the stockers and fit with a larger plate, but it's probably not really worth it IMHO.

 

mine and impul for 370z

 

I don't think you'd see much gains on those without boost.. Bigger doesn't always equal better.. Probably would sacrifice low end for some minimal high end gains without boost
