Im in the process of building a custom intake manifold. I'm not sure which throttle body I should get for it.

I'm looking for a small OEM TB thats simple and clean. Nothing but the TB itself and the tps attached, no iacv or other unnecessary crap.

I've used mustang TBs for other projects, but I want something smaller like 55mm or less. Anyone know what cars/engines have what I'm looking for? Ill be on a standalone, so I can use any tps.

Thanks

 

Why go with such a small TB. The big throttle body, the better throttle response. What motor are you using? Might help give a better answer.

 

Its a twin TB setup im experimenting with, overall the flow will be greater than a single larger TB, just gotta start with small ones to avoid overdoing it and killing my intake velocity.

 

Ahh, that would make a difference. Here are some of the TB sizes for the Honda motors.
