Hey everybody, im trying to figure out the California smog laws for engine swaps. I have a b18b1 motor in my ls, and want to swap a b18c1 or something maybe greater? I just dont know if it will pass smog/be legal, i have a 98 Integra LS if that makes a difference.

 

your LS must be equipped with all the smog equipment that came with the B18c

 

So I'm reading I can get it bar'd for b18c1, would I just be able to throw it in and be good to go?

 

Also, the motor has to be same year, or newer, than the chassis for an engine change.

 

this and jus swap in the longblock along with the ecu and you should be legal as long as any modification made is carb approved. thats pretty much a complete swap since everything else is similar
