stock 92 ECU. Use the 97 distributor...rewire if needed.

Use the 92 injectors. Use the 92 harness.

Use the 92 manifold and IAC and TB.

Use the 92 header.

You could do a Z6 harness and wire it to the P28 or you could wire VTEC with wires directly.

for a Y8 in a DX, you will need to run the VTEC wires all the way into the passenger compartment. So a Z6 engine harness is a waste of time. You'll need to make your own sub harness.

BTW, OP, I forgot to mention that you will have a CEL for VTEC since your P28 will be looking for it and the y7 does not have it.

For the guy who said something about using the OBD1 distributor: nah. You can rewire the OBD2 one. Some of the Y7 distributors plug right into the OBD1 plugs. The 96-00 used a few different distributor harnesses all ***** nilly.
