Just to double check, you have the motor mounts that look like this, correct?
It's been a couple years since I did the actual motor swap in my ZX, but the major issue I remember running into was the trans running into the tunnel, but I'm using a 700r4, not a T5. The T5 is (from what I remember) smaller. Double check you're not contacting anywhere on the bellhousing, frame rail, etc maybe?
