I think the theory is that the 3.2L in the boxster makes 258bhp and the 3.4L in the early 996 makes 300bhp. Partly the differences are due to the airbox, which is truly pathetic in the 986, as well as exhaust.
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.
