what car am i looking for when i am looking for a bigger throttle body....90-93 integ or can i use somthing else? can i use a itr one? my map is on the fire wall i cant use one where the map is in the throttle body or can i? need help i am a dumb *** when it comes to stud crap like this

 

GSR or b16a2 60mm throttle body..
they can be bored out to 64mm if needed..

ITR throttle bodies are very overpriced but can be bored out to 65mm and tapered out to 70mm ...

Or just bore out your stock b16 throttle body to 62mm (ITR spec)..

 

I've been conteplating a H-series TB.. After market units seem to be coming down in price. Especially no-name used units in the classified forum..

 

Jhill on here bores throttle bodies and does the best job I have seen.
