Here is the scenario.
I have a 1989 Toyota Corolla with a 1600 4AGE engine 16V. I bought a Silver Top 4AGE 20V 1600 Engine for a swap. The problem is , I did not get an ECU.
Will I need the one for the 20V engine? will the old one from the 16V engine work?
If in case I need one, Where can I buy one for a reasonable price?
Thank you
