You should not have any issues with this swap. Just make sure all the necessary components are used for the ECU to work and go have fun.

If you are looking for a significant increase in power and start looking to change anything from stock, such as, heads, intake, exhaust, etc. etc. you will need to flash the ECU or replace the PROM chip with an aftermarket unit with all the new components. If the swap happens and the car is having issues running these cars were made with this engine and the ECU will transfer over to yours.
