So would the referree in california be a bitch if a person had a ls/vtec setup trying to smog. Since its a b16 head on top of a b18a1 block, you would need the ecu for the b16 for vtec right? just felt like asking because taking my car to the ref when i've got an ls motor was hard enough, shit they figured out my name by the third time i came trying to smog my car. CAn anyone please explaine about the ls/vtec and smog. will it go through. Will you fail on visual inspectio???
