if i have a obd2 to obd1 jumper harness do i need to change everything else to obd1?

 

no. the crank angle sensor just wont plug in. everything is plug and play. if u have the upright throttle body manifold on the ek. keep if for the z6.

 

Most of that isn't true. CKF sensor wont plug is because the Z6 ECU doesn't have on, you're running an OBD1 ECU so it doesn't matter anyway. You can't use the Y7 intake manifold because of the 3 wire IACV (besides that they don't flow well anyway) The swap is not entirely plug and play, you'll want to reuse the OBD2 alternator and get a set of Y8 or OBD2 B-series injectors. You will either have to build a custom distributor using the Z6 housing and OBD2 CKP/CYL/TDC sensors, or use an adapter harness or cut and splice distributor plugs.

 

I cut off the obd2 plug and soldered on the z6 dizzy plug. there is some wire extending you have to do for the sensors on the intake manifold.( i just cut off all the tape and wire loom and rerouted most of the sensors and that was enough) the IAT needs to be extended (dotn mix it up with the purge sol.)

 

You'll also need to swap the Y7's IAT plug (square) over to the Z6 style (round) or put the Y7 IAT into your intake arm.
