I have a D15B2 engine in my 90 Civic DX. I want to do a little work to it. I have a ZC single cam that came out of a CRX Si model and Trans. Questions are can I swap the head off the ZC and put it onto my D15B2? I already have the engine harness, Si ECU, and Resistor box. Will the Si trans work on my D15B2 engine? how about the Clutch, flywheel, disc from the ZC trans working on my D15B2. Also I notced the ZC single cam exhaust manifold had the same bolt patern as the D16Z6 engine and bolts right on. When it is time to get an exhaust manifold, can I use one off an 92-95 Civic EX/Si to work correctly on either the D15B2 or ZC head.
