but it should bolt right up to the manifold right? i was thinking about the P.P.tb and it does come with a spacer i believe.
Yeah, it will bolt up. If you get the p p it comes with the spacer.
would a p p throttle body be much better that a stock ported one

Would you gain anything going to a larger diameter TB if the intake is still the same size?

if you have the 85 mm intake to go with the tb yes.
I would say it would be about the same gains as a ported factory tb but bigger diameter. The less you have in the way the better it will breath.
