i got a question.... the D16aZ6 came in the 92-95 si and ex... right??? i just wanna make sure.

for your harness u will need to run a wire for VTEC, and for the knock sensor (i believe)
and ya, the D16z6 came out of the 92-95 si, Ex and some del sol modles.

Well D16z6's are OBD1 motors, the harnesses are a bit differnt, so its not like you can plug a OBD1 computer on your OBD0 harness. But the actual engine harness will work from the d16a6 onto the d16z6. I would put a vtec controller (apexi/fields) to activate the vtec solinoid, and use the controller to also riching your fuel curve.

hey jeff... i cannot afford a vtec controller right now... so what do u think i should do?... i'll apprecite your help.

Put the motor in, and just drive it without vtec, until you can get a cheap controller... You can wire in one of those RPM activated switch, and wire it directly to your vtec solinoid. It will work. But you can run a bit lean when vtec hits.

So if you are really low budget, and need to get a bit more fuel, you can take the old coolant temp sensor off the back of your block and plug it in, and just let the fucker hang in your engine compartment, it will think the engine is always cold, and go full rich.

Btw, you will need a new plug for your coolant temp sensor reguardless for the Z6, since it is mounted on the T-stat housing opposed to the back of the block.
