+1 on the GT35R.

Fantastic for 500+hp, responsive, durable. Tolerates a wide range of displacements -- I've seen them on engines from 1.6L to 4L+

And 8:1 isn't too high on the compression with a well-tuned EFI system.

We recently used a GT35R with T04 turbine on an ultra simple, budget-build 964 engine. Stock cams, stock heads, stock exhaust manifolds -- not even B&B headers -- and a huge muffler. Kind of a "Ruf RCT" style layout.

450hp/460tq to the wheels at only 0.9bar boost on 91-octane pump gas.

Really drivable, despite crummy exhaust manifolds.
Silly fast spool up. All done by 6,000rpm, no need to rev it way up.

The client also asked for a "high boost" setting for when he runs 100-oct on the track.
522.3hp @ 5,169rpm / 549.4tq @ 4,831rpm -- Dynapack chassis dyno, 1.2bar
Not bad for a budget setup.

An absolute ball to throw around on the street, and a terror on the track.
