I have an auto 1990 gs db1 that has a b18b1 swap. Correct me if im wrong but b18b1 are only in 94 and up right? My question is i just installed a cat for a 90-93 integra... but since i have a b18b1 i would need a 94 and upp cat converter? I just smogged it and NO went from almost 1.4kppm down to 45-47! Is that normal to drop THAT low? Its a brand new cat but i did not expect it to be that low. Also my co went from .60 to 1.60 on the 25mph test. Is it becausw i have the "wrong" cat or is it just a bad o2? ( isnt a cel suppose to be on?)

Appreciate any ppsitive input as i am a total noob
