This guy's success has long been a good point of referance to me that a 3.3 CIS can get very happy with a 60mm compressor. It is also might be seen as a good argument for proper hot side sizing and ball bearing center section. Note this is only a single BB turbo. The GT's are dual BB.

Tried a number of K27/TD04 Variants, 355/355 was the average, but the 60-1 SBB made a huge differennce in top-end power & spool up (torque came in like 800rpm sooner with the DBB) over the bushed 60-1 before then.
Went from the bushed 60-1 to a SBB 60-1, rwtq increased from 150rwtq @ 3k to 300rwtq @ 3k: huge streetablity increase: which is why I dismissed spending the dime on cams.
