I live in San Diego and I have a 89 YJ with a tired motor and that multiple expletives deleted carburetor. I want to rebuild/replace the moter and add performace upgrades such cam, MPI fuel injuection and 4.0 head. My question is what have California jeepers done to upgrade their motors and stay smog legal? As far as motor rebuilding I am not good and will be having a shop do the work. Budget is about 6k.
