I have a 2000 Hx, and I am wanting to put a hybrid engine in. The engine consists of a B20 bottom end and a B18 top end. Will an ecu work from a B18 motor or am I just out of luck.
I assume you're putting a C series head [VTEC] on the B20. You'll need a computer with VTEC capabilities. Also if you're using a GS-R head, you'll need the GS-R computer [P72] to operate the secondaries on the intake manifold.
