so i found this super bad ass turbo t top one owner monte carlo that has not been abused at all. the motor is rebuilt Due to blown head gasket and sitting in the car almost put completely back together. unfortunately the guy died of cancer before he could finish it. i bought the car from his wife and son and will be finishing the project. my question is do i have to run all the smog junk? i would like to simplify the engine and Im in nm which currently has no emissions. also what can i do to improve the stock performance of the engine.
