i have a 88 crx si with a 91 b18a in it. i need a new throttle body and was wondering what would be my best bet as far as bore size.. is bigger better ? its all motor right now but plan for boost soon. i have a skunk 2 mani already but not sure how big the bore area is on that. also i see that the edelbrock tb`s come with new tps and alot of other companies dont. if i have to put my own on how do i calibrate it? and last but not least, my car is obd 0 and where other tb`s have the fast idle valve mine just has 2 ports in and out for the coolant not that large piece bolted on the bottom so do i need a specific obd0 tb or can i use any of them and just bypass the coolant lines? thanks alot for your help. any advice would be great.

 

anyone?
