Hi all,

I have a 1977 with a bad motor.I have a 1982zx motor which is fine,so will the 77 wiring set-up be the same to hook right up to the 82 engine.Will I have to change the computer.

To at least swap out the ECU and engine harness.

Or, depending on which head you have on the engines, if the exhaust ports are both the same (square or round) you could just swap the long block of the ZX motor into the car and run the 77 intake etc as a whole.

Might even be easier if the head ports don't match, to swap the head from one to the other instead of messing with the wiring harness and possibly having more trouble down the road...

Of course, this also depends on what is wrong with the motor in the 77...
