I been thinking of either installing a 4AGZE or a 3sgte to my 90 corolla sedan. But i dont think I could make it smog legal with the 4agze in california so that y i been thinking of the 3sgte. For the 3sgte I know i would have to make custom motor mounts. What kind of work would it take to install a 3sgte to a 90 corolla sedan AE92?
