Re: Which Throttle Body?

For a stock car? Leave your stock throttle body. Worry about it with heads/cam, etc.

Re: Which Throttle Body?

Why do you care about making over 300rwhp and not track numbers (the stuff that actually counts)?

I suspect it says "TPiS" on it:

TPiS sold a throttle body that was a stocker, bored to 52mm. The stock TB is 48mm, and has a plain black plastic cover.

They also sold the TPiS cover plate separately:
