B16 smog in Cali

I want to get a 16a for my 91 integra but i hear people saying it wont pass smog, or ill have to buy a whole shit load of stuff to make it pass. But then i heard people saying that in japan they have tougher smog laws then we do and the engine will pass smog, can someone with a swap in there car please help me out here. I just want to know will my car pass smog if i have a b16a in it, and if not what do i have to do to make it pass smog?

i am battling this question also but signal autosports told me it was legal so i guess so

yes, that's true. if you live in california, this is the part where you'll start to whine... and get grouchy. one component that's needed to pass a smog test, is an OBD-II ecu. certain I/H/E's are 50 state legal. if you plan to swap, you will need to swap a motor the same year as yours or older.

i heard it was legal as long as u have a usdm version. but if u get jdm then thats when the trouble starts

thanks guys for your help.

You mean same year as yours or newer right? :)

i heard jdm could be legal but the whole conflict comes in as what are the laws partaining to this
