Question:

Hi, sorry I'm kinda new to working on cars, also new in CA. But is this carb legal? Also do I just use the stock rad for these or is it better to have aftermarket parts? Nissan Rear Water Coolant Bypass Pathfinder Upgrade Modification Kit, VQ35DE - Nissan 350Z / Infiniti G35 - Jericho Jordan Shauf

Answer:

Hi Jericho, these are not subject to emissions regulations at all, so CARB doesn't care about them. And the radiator doesn't matter either, this is entirely a modification done on the engine side.
