I've recently bought a GTs-t with similar power from an RB26 and its not THAT bad.
Its pretty laggy, the clutch is a bit of a bitch if your sloppy with it(in the wet it'd be wheelspin city - HKS Twin Plate), but even with 272 cams down low it doesnt buck around or anything.
Does drink the fuel, and certainly wouldnt want to drive it everyday.
