65mm throttle body

[IntenseBlue]

Has anyone installed a 65mm throttle body on a stock H/C/I car? Did you notice anything.

Also, what hp level should I upgrade to a 70mm?

IMO, stock tb is best for stock heads.

You can use a 65, you aren't going to feel anything but a couple horses may be there (when i say a couple, less than 5).

Back when I was mostly stock I put the FMS 65mm on and felt better throttle response and a SOTP gain (nothing dynoed). I only put a 70mm on when I did the Fox conversion because I got a better deal than the 65mm I was planning on buying. If you stay N\A instead of forced induction 65mm will be fine.

70MM is too big for stock parts.
PM me if you're interested in a used 65MM throttle body and EGR spacer
