With a 3.2L with a 996 throttle body, full exhaust, 987 airbox, pullies, and the plenum, it should produce as much or more than a stock 996 given the very small displacement difference.


As to lowering the motor.

The stock setup is some M10 by 83mm studs.

I purchased M10 by 100mm studs along with 4 M10 .5" spacers.

so you basically support motor, remove stock nuts and studs

Lower motor by .5" or more

slide in spacer, thread in stud, and tighten nut and you're done.

Took maybe an hour. I didn't lower the tranny as I believe the .5" difference should not cause any weirdness with drivetrain angles.

Thanks for this any pictures of this set up? This arrangement sounds like the rear mounts which would lower the transmission would it not? I can't recall the exact configuration up front but would have thought that there would be no facility to lower there......I will have to did up my old mount and have a look
