    The 53.8 in 47 ex would be the best turbine wheel for SR20det, run that in T2 .61 turbine housing externally gated.

  4. More video to share. This is an R33 GTST powered by one of our ATR45SS1 turbochargers at Hitec drift last weekend. Car's currently making 401rwkws on E85.
  5. The SL205 makes the same power as a 25G with better response. If your current turbo is not blown I can have that modified to the same specifications as the 20.5 with a 10cm with turbine housing supplied for less then half the cost of a new turbo.
  6. It acts as a normal anti surge slot. There is a lose in compressor efficiency. I did a comparison years ago result is in this thread. There was a lose of 300RPM and 11kws with that particular turbo used.
  7. Looking to spend $500 to do that sleeve insert. One more Tuning video to add. This is one of our ATR43G3SAT Rb bolton models. making 324rwkws on E85 fuel internally gated.

  8. Yes can be done. Dyno footage of ATR45SAT Powered R33 GTST, making a super responsive 339rwkws @ 22psi on pump 98 fuel. Video footages from Vic-drift last week at Calder park. Car is an R33 GTST powered by one of our high flowed R33 Turbochargers, making 330rwkws on E85 fuel.
  9. Responsive 400awkws single for an stock unmodified Rb26 engine. After doing trail and errors I think many aspects of the Rb26 is over rated. As a turbo mob, I have unlimited turbocharger resources in modding my own GTR, Goal was responsive 400awkws E85 fuel, single externally gated on an unopened, unmodified factory engine, that means, no cams gears, no cams, no bigger bottom ends, purely stock standard. After trailing various housings plus mixed and matching wheels. My final result on a unopened S3 R33 GTR was 411awkws on E85 fuel, It made 200awkws and 20psi by 4000RPM. Power band was streetable and close to factory twin's response. Turbo was built with normal inconel turbine, cast comp wheel, ceramic ball bearing, nothing fancy. Light blue ATR45SAT BB vs Red stock Rb26 twins:
  10. GT30 turbine wheel in .82 rear is a good combination for a Rb25det NEO, it performs well both internally or externally gated. I would keep that housing. Getting better response you can down size the comp wheel to 76mm or one of our SS2 Billet 74mm wheels with a none surge slot comp housing plus a 4 inches metal intake pipe. That would be quite responsive to drive and capable of reaching around 300rwkws.
  11. ATR43G3SAT turbine is more efficient then a GT30 turbine. This is the reason that I recommend to run them in .63 rear with Rb25det engines. Both comp wheel and turbine housing is smaller then GT3082 in .82 rear, so that would be more responsive in comparison. Since you already got the GT3082 you might want to use it, if you find it too laggy for your application we can have it modified for better response, down size to ATR43G3SAT or looking into ATR45SAT.

    Mail box is active now. I've emailed u the quote. Thanks.

    Yes, there are two angular contact bearings in side a bearing cartridge. In most of cases it's the raceway of the bearing wears resulting that play.

    You can use an actuatored bleeder valve on the front pipe to resolve back pressure issue to certain extend. I was more or less referring to topic. For BB models they don't have a thrust bearing wear problem, it wears on the bearings and race way of the cage. There is no alternative way of repairing them apart from installing new bearing kit.
  15. hypergear

    Its usually result in an unbalanced pressure load on the turbine shaft. I believe most of bolt on GTR's full exhaust system is too small for the twins, I would put an bleeder valve on the front cat. With bush bearing -7s, you can install over sized thrust collar assembly and increases the capacity of load, or go bb cores.
