So i have a 03 type s and recently my k20a2 head blew. I have a 5 spd trans in it but i want to put a k20a3 in it for now. What would i also need to downgrade like ECU, Engine harness, ect... and can i put parts from the A2 engine onto the A3 like oil pump, ect. Thank u

Why would you want to do that?!


You'll want the wiring harness, You'll need kpro or the entire matching ecu and immobilizer.

I only had the idea of it bc my trans is recently changed and the body has no rust so i want to keep the car. I just cant afford to get another A2.
