Hey folks, whilst I was out at EVO in Jan I got to try/test their GT660 kit and GT610 kit (both based on the same Garrett turbos) and both designed to do away with the K24 as a notion of an upgrade The GT660 has been out for a few weeks and now so is the GT610 kit.

Features:
-EVOMS / Garrett GT High Flow turbochargers w/ patented “quickspool” turbine housing
-EVOMS custom wastegates w/ CNC machined billet aluminum mounts
-EVOMS Machined oil line conversion adapters for turbochargers
-Denso spark plugs
-OEM gaskets and installation hardware
-OEM Bosch ME 7. 8 engine management system with EVOMS proprietary GT610 software calibration


Note:
HP Gain: 611 HP
TQ Gain: 603 TQ

For an easy-to-do bolt-on the responsivenes and power was certainly better than anything from a stock K16 or stock K24.

NOTE: I'd advise a clutch upgrade of some sort
