I have a 15% pulley, dinian intake, jcw exhaust. I would like to upgrade to 380 cc injectors and a tune. Either jcw or another. If I do this will I pass smog? Also can I pass smog with a different head or a cam and matching tune? I currently pass smog just fine. I have 200k miles and figure I will need a new head or motor soon. I want a little more from a new motor.

 

As long as you are not throwing codes the tune and all the enternal stuff should not be a problem. its the visual inspection that may give you an issue. All modifications are suposed to be CARB approved with a sticker or some kind of plate. But if you are already passing with the exhaust intake and pulley you should not have problems with injectors and a tune. As long as you stay within the levels of the test.

 

I'll be fine for the sniffer

Depending on your smog tech they'll want a carb sticker on the actual part the intake especially since it's the most visible
