I'm selling my GT42R's 74mm wheel. After running them on the dyno, I would recommend them to anyone with a Stage II motored vehicle. In my V8 Bowtie application it made 1500foot lbs of torque at 4400 to 4500 rpms [full boost 29 psi]. In a V6 Stage II application, spooling these should not be a problem. These are ball bearing units from PTE.
BTW. The GT42's replaced my pair of Turbonetics T76 BB turbos and these GT-42's bolted right in with the only modification being that I had to trim some material off the base of the turbine housing to make room for my AN wrench to reach the oil drain fitting. Physically, the turbine housing is no different than your standard T4 flange with a 4" V-band for the down pipe(s).
