I'm looking at a few 88 - 89 convertibles. All of them have the California emissions. How much does that hurt performance and does this option make the car more expensive as far as parts are concerned?
Re: California emissions - how bad does it hurt? (marps)
My 87 vert is a CA car. The only comparison I have is my 85 non-CA car. Other than a couple of vacuum junctions, I don't see a big difference. From what I understand all of them have the dual pre-cats and AIR injection system into the big cat. The ignition, fuel, intake etc. seem the same as on a non-CA car and there are not seperate part numbers. I wouldn't worry about it. Perhaps it just needed to pass a slightly higher standard with the mostly the same equipment to earn the CARB stickers.
I am in the process of just removing it and keeping it in a box in case I move back to CA some day. Polution is a matter for tuning. A well tuned car will not polute.
