I'm doing a mini swap on 97 civic d16y7 block with a z6 head w/ y8 crower stage 2 cams. We're using adjustable cam gears
Using a y8 obd2a ecu

How to I find tdc from the cam gear?
And once the car is timed it has to be 4 degrees retard correct?

 

I believe that's only when using a D15 block, Y8 and Z6 blocks have the same deck height
