Ok...

My housemate's 87 crx si got totalled (story later) from behind, and everything from the doors up is fine. He's looking for another CRX, and he found a really good price on an 87 CRX DX.

What parts would need to be swapped into the DX to make his Si engine run in that car? Obviously the ECU would go in, but can the wire harness be plugged in without tons of custom wiring?

Also, is the DX fuel pump/fuel line capable of supplying enough fuel to run a stock 87 CRX Si engine? All answers appreciated. Thanks!!

Oh, and also, is the suspension in the Si the same as the DX? thanks!!
