Think i'll be needing a new turbo shortly and wondering on whether to get a Stg 2 T3 (4x4 compressor, 360 bearing), or a T34 (.55 cut back blades double oil seal, 360 bearing).

Its for a 2wd Saff with 500 cooler, 803s, would like around 310bhp at 19psi held (20/21psi peak). The car wil be used for track days and some summer road use.

any recommendations/opinions, if the Stg 2 T3 is upto that psi, then it will have less lag, but will the T34 have any aditional benefits to compensate for the addittional lag over the T3?
