Yup, GT35R has T3 turbine/flange, as does the KKK units. Bolts straight onto your header
I don't use an oil drain tank. My car is aftermarket turbocharged, and I (and many others) simply gravity drain the oil to the sump drain plug... works very well
IMHO, a 1.06A/R turbine HSG will be too laggy on a 3.3. Maybe on a 3.6 it'd be fine, but for a 3.3, I suggest the 0.82 A/R HSG.
