  1. Well, with the current turbine housing on it won't make any differences compare to before the turbine wheel was grinded. We can supply a .63 or .82 turbine housing that is machined to suit your wheel. With a customized wheel it is hard to approximate the output.
  2. By trimming down the inducer height can result in increasing of response as gas velocity is higher when they squeezing though smaller gap. Been used on a smaller engine previous perhaps assume it had the right turbine housing, or it might be be people experiencing concepts. To make this work the turbine housing needs to be sleeved up to the height of the wheel tip then machined to suit the wheel profile. Can be done.
  3. That is the wastegate lever extender piece. They all been tiged by a well know member here, I haven't seen any with this issues but I guess shit happens and I will rise the concern. It won't damage the turbocharger or the engine, If you like to send me the adaptor piece I will have it repaired for you under warranty. If you decide to have it welded your self, make sure preload the actuator rod after welding. That will makes a big difference in response.
  4. I can ask him next week. Going back to tune my Kia . As far as the result concern, it doesn't seems like this turbocharger is maxed out. As shown with increase of boost result in evenly increasing of power and torque. When the turbocharger is getting maxed, the upper rev power and torque usually merge with an additional psi of boost. I guess it was late and we all got excited that it made 400rwkws+ and left for hamburgers.
  5. Thanks for your support. This particular one will cost $2500 to produce, the ceramic rollers alone is $400. Plus all other little engineering work, the making of it is very involving. I can also build you a ATR43SS4 in VNT turbine setup for the same price. Which is I believe para with GTX3582 in terms of HP, without the lag.
  6. The VNT system made a large turbocharger drive like a baby turbo while still been able to pull the numbers up top. I've overlaid today's result against a high flowed R33 turbocharger's result:
  7. Following up on the ATR43SS3 BB VNT turbocharger 93 model R33 GTST Forgied CP pistons, valve springs and stock every thing else. 800cc injectors 600x300x75mm Front mounted cool Brae high mount exhaust manifold HPVA 50mm external gate plumbed back. Xforce 3inch Cat back exhaust 100 Cell Cat Profect B electric boost controller 4inch intake pipe Adaptronic Plugin Power so far is 407rwkws @ 24psi E85 Fuel HyperGear ATR43SS3 CBB VNT Turbocharger. Turbocharger reached peek power of 407rwkws on 24psi of boost This result was archived by a large size turbocharger using stock cams and stock cam gears and boost. It is not enhanced through larger cams or cam gears. This turbocharger had big turbo's top end while retains small turbocharger's down low. I've overlaid my result against result from a high flowed stock R33 21U turbocharger.
  8. Yes they will work. Not sure how much room is there as it will require two actuators for an internally gated setup. SS3 VNT Final result of peek 407rwkws with 24psi on Stock inlet manifold, cams and cam gears. it read 265rwkws @ 4000RPMs and 95rwkws @ 3000RPMs. Peek 24psi by 3750RPMs and Made 20psi by 3700RPMs. I'm still off the target of 3500RPMs. Its reaching the limit of VNT capacity working with such a large size turbocharger. Even tho, still super responsive to drive on road.
  9. Next week I will be finalizing the tune on the SS3 so probably the week after. At moment the problem is manufacturing them at affordable cost, I don't think its reasonable today to charge some one $2500 for a turbocharger regardless how good it might be. Unless its made out of gold.
  10. Because the GTRS turbine is only capable of pumping up to 280rwkws maximum so any thing that is larger then what ever the limit is, is totally unnecessary, bit like the 82mm compressor wheels on S14 T28 turbines that some Chinese manufactures dumped on ebay. The GT2876x is probably useful when comes to mild V6 or V8 engines upgrades which you can run a single turbo manifold with half of the engine capacity to drive one turbocharger, while using the large compressor to force feed all cylinders.
  11. SS1PU VNT, prediction is 20psi by 2800rpms and maxing out at 320rwkws. The external gate will be screaming all the way. might be able to make it run internally gated, more tests will be carried out.
  12. I want to fully explore the potential of the new idea, and find a way to manufacture those at affordable pricing. Don't have SS1.5 on SRs at moment. only have it with Rb25det which is super responsive.
  13. It has nistune installed. But the response and torque delivery is identical to factory turbo. So if you run it on 10psi with stock ecu it has stock turbocharger's drive ability.
  14. I can high flow stock turbo so they work fine with factory ECU and still make bit more power then standard. But they don't make much power if you have plans for supporting mods. Light blue is factory turbocharger.
  15. Will be in process of building a SS1PU using VNT system. Pretty confident it will match or beat HKS 2530's response while making same power as a 3071. This will bring some joy for RB20det owners.
  16. Little update. To make the SS3 even more responsive I've had it remade using ceramic roller bearing cartridges instead of steel. With the vacuum leak repaired this turbocharger is super responsive, It has made a very fast car. Can feel the turbocharger whistle to boost with touch of throttle and goes blastic as it revs out. Made me thinking, wither if the SS2 BB VNT should be more responsive without that vacuum leak. I've taken a little shutting down video footage from my SS3 VNT CBB turbocharger, as you can see this is a very big turbo, 394rwkws on E85 is not a real lot for some thing in this size. Goal is 20psi by 3500RPMs, Its going back for a return next Tuesday, and I'm very positive about it.
  17. No its just all air cooled under the bonnet. We were playing with it few weeks ago and didn't notice the vacuum hose. It now has also picked up some thing like few hundred rpms of response.
  18. Just found out the vacuum hose to my external gate was melted as it was touching the dump pipe. lol. that explain the strange wavy boost curve. Taking it back for another tune and posting more result next week.
  19. Well I didn't find there are much differences between Status dyno and Mainlane they all within 5kws. The mileage reading from quarter mile run is a pretty good prediction for power level. With ATR43G4 that I made 431rwkws with, that was running 28psi of boost. The turbocharger is equivalent to a 3582 in .70 comp and .82 turbine. its not much different compare to others using the same turbocharger at given boost level. The SS3 is a large turbocharger, So it is expected to out put that level of power, Try the FP 3076 with a solid .70 none anti surge cover, it should be maxing out the same result using a lot less boost. Had the CAS replaced, and the car is running fine now. It had the SS1PU down low feel and went crazy after the external gate opens. The Micky Thompson are now hopeless, wheel spinning from 4000 and on wards in third. Can run a ATR28SS1.5 that should be a more responsive version of the GT2871
  20. One more thing is The other car which some of yous are comparing with has cams and cam gears with much higher boost Level. Which means I will not be able to reach his result using his turbo, how ever he should he able to beat my result using my turbo.
  21. Thanks for the feedbacks. Dynosheet to share?
  22. 93 model R33 GTST Forgied CP pistons, valve springs and stock every thing else. 800cc injectors 600x300x75mm Front mounted cool Brae high mount exhaust manifold HPVA 50mm external gate plumbed back. Xforce 3inch Cat back exhaust 100 Cell Cat Profect B electric boost controller HyperGear Latest Ball bearing ATR43G3 4inch intake pipe Adaptronic Plugin Power so far is 395rwkws @ 23psi E85 Fuel ATR43SS3 VNT Turbocharger. It made 394rwkws on 23psi of boost so far I must address this result was archived by a large size turbocharger using stock cams and stock cam gears and boost. It is not enhanced through larger cams or cam gears. As shown, the boost behavior in reference to degrees of freedom given by the actuator controlling the VNT nozzles. The whole boost curve shifts to the left as the nozzles stayed in the deactivation position for longer. Boost curve with VNT system fully engaged and fully disengaged: I should be able to get 20psi by 3600RPMs with few more hours of dyno time like what the fully engaged and disengaged boost graph shown, then disengage after it reaches that point. As we were adjusting the boost controller for dyno runs the car experienced some ignition problems so we had to call it a day. It will go back for any other run once I have it rectified.
  23. Its a Series 1. They all have VCT.
  24. It made 250rwkws by 4000rpms. It provides very consistent Gforce, turbo comes in with very little throttle and pulls crazy. I should be able to get 20psi by 3600RPMs with few more hours of dyno time like what the fully engaged and disengaged boost graph shown, then disengage after it reaches that point. I can now control how much lag I want with a boost controller.
  25. Boost curve with VNT system fully engaged and fully disengaged: I compared it with a earlier turbochargers that made same power range: SL25.5 (or billet T67)
