Sorry if this has been asked before but my search fu is off today. Anyways how much can I mod my engine before I have to get a powerstick of replace the motor mounts. I already have intake, spacer, and exhaust.
There is not necessarily a point of modding where you suddenly need mounts. Anyone's setup can benefit greatly from an engine torque dampner or better yet upgraded mounts. They will be very beneficial with a race header though, to limit the amount of movement of the engine and protect the race header from contacting the undercarriage or subframe. But I think that just by themselves they offer a significant gain in feel and performance of the car.
