Factory turbocharger will be stripped, both compressor and  turbine housings will be machined to suit a brand new core. This particular core  has up sized steel wheels, built with quality Germany made high speed ball  bearings. Internal gate flapper valve is upgraded with gate up sized. All  engineering work are carried out in Australia by qualified Australian engineers.

This is an Stage 3 high flow, minimum boost pressure it  will run is roughly 17psi depending on free flow the engine setup is. It supports up  to 287rwkws on pump 98 fuel. it requires working with  programmable ecu and bigger aftermarket fuel system. High flowed turbo maintains factory drive ability with a lot more power throughout the rev range. Braided oil line is  supplied  with this service, factory water lines, oil drain, cold and hot  side plumbing fits high flowed  turbocharger. 

This is an ball bearing turbo.  We use quality Germany made high-speed ceramic ball bearing cartridges. Not only  reduce bearing friction and oil drag  to minimum it is also capable of  handling high thrust load. The turbocharger would generate boost with minimum  throttle movement making the car extremely enjoyable to drive. 

I've personally owned many R33 GTSTs and been modifying  them for many year with current Rb25det project on going. I  do have a fair knowledge in them, do feel free to drop in an email for any  service related information.
