I realized that my question is not just a yes or no kind of thing. So I'll break it down into sections, that way everyone can help out with what they have done before.
I'm using a D16y8 block with a SOHC ZC (non VTEC) head is going into a '90 Civic 4dr which had a D15B2 engine with a cracked block.
For now we just want it to run and pass Texas emissions test. Will not be doing the DPFI to MPFI.
Listed below is the part - solution
Motor Mounts - Y8 driver's side mount and bracket
Y8 to current Tranny - Yes, all good
Clutch/flywheel/linkage - Good?
Shifter linkage - ????
Y8 to ZC head - oil control jet issue, compression issue (pistons or shave head), DX(B2/B7) timing belt
