i have a b16a in my 88 crx and im doing some bolt on mods like dc header, unorthadox racing pullies,injen cold air,professioal products intake manifold,mugen valve cover,nology wires,ect.and im wondering what throttle body to go with and what size i can go on the parts i have.

the intake manifold is 64mm on the inlet,i was thinking of the skunk2 66mm but dont want to second guess.and if so can i go bigger,or will it not give me power.

 

You go bigger when the engine needs more air. Like say when you have cams and what not. Just get a B18C5 IM and TB. Then put some cams in her.
