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 a good answer! The "problem" I have in general is that I have seen any conclusive dyno figures on air-mods, many reports of "seat of the pants", and then on the dyno there isnīt much. Will be really interesting to find out how yours run when you have had the chance to evaluate.
