What to do to put 22r motor into 91 cressida?

To install a 22R motor into a 1991 Cressida, you'll need to start by removing the original engine and transmission. Ensure you have the necessary engine mounts, as the 22R may require custom fabrication to fit properly. You will also need to adapt the wiring harness and possibly modify the exhaust system for proper fitment. Finally, ensure all connections, such as cooling and fuel systems, are compatible before starting the engine.
