Well I eliminated the fuel pressure as a cause unless 1.5 more PSI is a problem, though I can't see it causing vibration.
Rented a tester kit from the local parts store tonight. Mast requires 58.5 PSI at the fuel rail and I have dead on at 60 PSI according to the tester. Since I can induce vibration just by increasing RPM's in neutral there wasn't a need to test it under load. When blipping the throttle I see a split second 1 PSI dip.
On to tripple check the engine mounts and trans mount and then it's time to pull the tranny and check the clutch.
I was thinking I can take the clutch off and run the motor with just the flywheel to see if I still get horrible vibration at 2K RPM's. If it's still there then I may need to borrow a flywheel or get the balance checked at a shop.
Will keep you guys posted.
