i was wondering if i would gain any power from putting on a larger throttle body on a stock intake manifold(with sri intake) and if so how much? would a larger tb fit on the stock manifold? i think the stock tb for my model is 55mm, what would be a good size to upgrade to? im thinking about buying a new intake manifold later on down the line so keep that in mind as well.

B20 tb, what size is it and will it fit/work?

thanks!

 

well yeah if your gonna go bigger later it cant be bad maybe right now you wont see the results your looking for but when you have the match of the bigger two it will be much better results especially in NA trim

 

I would spend my money elsewhere first. TB's are not worth the money on N/A motors in my opinion.
