Tranny/Engine mounts?
I want to keep the vibration as close to stock as possible, but also want to try to eliminate as much engine movement as possible. I assume stage 1 mounts would be the best, but can someone tell me how they ride (my car is my DD). Also, which mounts do you recommend? (ottp, zzp, etc.?)

You cant really have both, its either one or the pther, and mounts that reduce engine movement will increase vib in the cab. but i would go with John Powell Mounts....waiting for mine right now actually!

there are 4 mounts that position the engine/transaxle in place.
There are two "torque axis" mounts each side, at at the approximate center line of the motor horizontally.
The drivers side mount is under the fuse box, and is a very soft mount; its round, and is anchored inside the driver side frame rail, and attached to the top of the transmission with a 3 bolt plate.
The passenger side mount is beside the "front" of the motor (east-west orientation to the north-south of the car, a "transverse" engine position.
It is a fairly hard mount, it is triangular, anchored to the top of the passenger side frame rail, and attached to the front of the engine with a 3 bolt mount plate to a two bolt engine plate.
There are two mounts at the front and rear at the lower third of the engine/trans unit
The lower mounts front and rear, attach the front of the motor and the rear of the transmission to the cradle in roughly the same plane, mid point of the powertrain assembly.
The Delta cars were designed around an automatic transmission placement. The orientation of the axle out put shafts at the transmission are centered on the outboard suspension knuckle spindle center.
The manual shift cars are not. Rotating the motor up at the back and down at the front moves the axle output shafts at the transmission rearwards, centering them on the outboard suspension knuckle spindle center.
Using a smaller voided bushing dicated by the amount of available space makes for a firmer positioning and facilitates rotation.
NVH (Noise Vibration Harshness) is acceptable if installed correctly. It is possible to have the motor shift sideways when installing rotated mounts incorrectly, and thus have more vibes than expected.
Poly inserts are not a good isolator for nvh, and therefore make a lot of vibes, but are very cheap to make.
hope this helps.
