    The SS1PU has the smaller bearing housing. So they are same the as earlier version. G2/SS2 and larger versions runs the larger T3x bearing housing. Those are easier to install. Best to have a look at the installation walk through for both in page 1.

    Can reuse factory compressor end, not the turbine end. Which gives it a factory look. Birds. For the drags you will need some 275 MTs, run them at 18psi, and worm them up nicely. If the launch is perfect then a good time is more promising. One thing I didn't like about Heathcote is how they washes rubber residuals at the start of runway with water every time a car lunches. So we always taking off on wet tires.

    Good work birds, some thing like that is ideal for every day driving. Yes the SS1PU has been upgraded few times since. The latest one is engineered to prevent the level of boost tappering in upper rev range more specifically for an internally gated application. So with few more psi of boost it will have better upper rev power and torque.

    Yes, got plenty of bits ready to start when you are ready. Also recently got a CNC lathe in place, unfortunately no one knows how to get this thing to work. I'm having a programmer in next week setting up some programs for compressor and turbine machinery work. It will be able to save heaps of man labor and work at a much faster rate. Overall saving will be put on to our customers.

    Tune was cancelled today, I guess Trent had some thing unexpected happening. now rescheduled for next week. Also we are a little over stocked with our billet SS2.5's parts. Now offering cheap for $850 each complete turbocharger with oil line. Those are capable of doing about the 270rwkws on pump with excellent response. Details of this turbocharger's performance externally gated on E85 is at: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-364 This will be a complete turbocharger. with a .60 comp and .58 turbine with a Nissan 6 bolt IWG assembly. It is a brand new turbocharger, Not a high flow service

    this are the OOOOO motorsports 1200 cc injectors arriving for tuning tomorrow. Hopefully they idle smoothly and sitting the car closer to the 500rwkws mark. Thanks for every one whom recommended web designers. I've spoken to asapwebsites since he's local, new site should be up and running very soon.

    SS2.5 in stock R33 housings It won't make 300~340rwkws on a Rb30det. Probably a super responsive 250rwkws, rear end is too small for that engine. Induction pipe needs to be at least 3 inches.
  8. hypergear
    Minor update. Dyno reading of another SS2 turbocharger sent in by a customer on a R33 skyline. 307rwkws, 98 fuel, actuator pressure. By the way I'm planing to re-launch our website with a modern touch. Is any one here recommended for website designing and coding?
  9. hypergear
    Well this is a older high flow that has been done three years ago. Taking advise from M35Scotty, today's bearing housing and fittings are all made for direct bolton applications which is a lot easier to fit. For diagnostics, remove the induction pipe for a visual inspection, if there are no circular markings on the compressor housing profile then have a feel for shaft play. If there are none in and out, with a sticky +/- <1mm side to side, then the turbocharger it self is probably ok. Other wise it requires overhaul which we can sort that out without much expanses.
  10. hypergear
    You can send the turbocharger back for a check up. There is a primary oil restrictors in side the sump that Scotty made a comment on, which required to be drilled out.
  11. hypergear
    Any 2.5L Rb25det here?
  12. hypergear
    O2 sensor failed? it did the same thing on my 180sx agers ago. Goto PFC console and check the o2 feed back. It should be running out of a cycle of reach and lean or afr +/- 0.5 around 13. If it stays consistent then needs to be replaced. Alternatively you might have another split hose or some thing similar.
  13. hypergear
    Add in two more results from recently customers. This one is from iruvyouskyrine, Which is a Rb25det motor inside a R32 shell. Runing a ATR43SS2 bolton version internally gated with usual mods. Car made 312rwkws @ 19psi on Pump 98 fuel. And this is from another customer has a R33 skyline, usual mods, ATR43SS2 bolton version internally gated turbocharger on E85. Car made 321rwkws on 20psi.
  14. hypergear
    its 850cc with a fuel reg. the afr stayed at 11.5 till 5500rpms and rose to 13.2 by 7000RPMs. Which is maxed out. Now lets talk a little bit with that 345rwkws E60 result on a AUTO. Auto usually fall 15% behind a manual which means that is equivalent to 390rwkws manual power. Not only that, this power is generated from stock exhaust manifold with internal gate as a bolton high flow, I'm totally amazed it got there. So translate that into manual power then add additional 50ccs out of each injector, that flow rate is pretty close to getting my current result. If you find that high flow is too big, then I'm more then happy to have it modified to a smaller version for better response. Trent is extremely cautions with my car because its done couple of hundred dyno runs, and we occasionally take it to do quarters. its all been very safe or no differ then what he would normally do to a customer's car.

    They are pretty decent power for stock cams, and notice the power curve is still on the rise all the way to red. I think PZP should be pretty happy with this out come. Check if VCT is working, fully agree. You can't skip teeth on the timing chain with the SRs can you? my skyline picked up heaps of response after timing belt correction.

    Certainly a mixed of pessimistic and positive comments. Well this is the first SS4CBB Alpha prototype evaluation, so nothing is set to be final at this stage. This thread is dedicated to turbocharger innovations for Nissan 2.5L Rb25det engines. Which power delivery behavior or results in similar HP range gathered from other engines are not helpful. Taking account of your comment Micky_o. With the Mickey T tires it is quite driveable, in which it did has a smooth start following a very aggressive pull. It is different to the ATR45 trail in Feb, which had a much heavier exhaust note, with a sudden pull behavior. A set of 1200cc injectors are coming for the next tune, I will add some alterations to the current turbine system. The goal would be shifting the same amount of power 300RPM left of the scale.

    Keeping this thread alive. SS-4 Alpha ptotoype 1, Working with a 2.5L Rb25det and Tomei 264 / 8.9mm cams. E85 fuel, externally gated. This turbocharger made 465rwkws on 24psi maxing out 850cc injectors, Thick yellow is from today, the rest is the controlled run. Ordered a set of 1200CCs, looking to crack 500rwkws.

    Some updates from SS-4 Alpha ptotoype 1. This turbocharger made 465rwkws on 24psi maxing out the 850cc injectors that is installed without gain additional lag. With a set of 1200ccs on 29psi it should be getting very close to 500rwkws mark. Big thanks to chequered tuning again. Thick yellow is from today, the rest is the controlled run.

    Just stay on the conservative side I have applied deduction.. To calculate the total power level out put as a twin, the usual formula is 100% power capacity of the first turbocharger + 70% capacity of the 2nd turbocharger. So if the high flowed turbochargers are capable of 400hp each then as a twin they support 680HP, not 800HP. Which factory housing can support up to 350HP each, which works out to be 570HP as twin. another thing to keep in mind is that we are still dealing with a stock .48 rear housing, while the -5 has .64 rear housing. That makes a huge difference. Means to match the flow the exhaust side has to be larger. The capacity from standard highflows would be very similar to what you would get out of two -5s.

    With the bolt on SS2, Just had a quick chat with Trent today. The boost became controllable after the long stud securing the dump pipe was replaced with a shorter one. The car is currently sitting at 20psi and making 301rwkws on pump 98 fuel. He also said the gate is only restricted to a 40 degrees swing which they were engineered and checked to 70 degrees. I'm not sure if the long stud has forced its way into and bent the wastegate assembly that made the disc catching on to the rear casting, which I understand it would be torqued up tightly. Trent is trying to lower 3psi and fill in a little bit of extra timing. I will be heading down there to inspect the turbocharger on Thursday and it will be checked out and repaired by then.

    Result sent in from another customer. This time it is a ATR43SLSS2 turbocharger in a 8cm turbine. It is fitted on to a FJ20det engine in a Datsan 1600. With supporting mods final result of 257rwkws on pump 98 fuel.
  23. hypergear
    The billet SS1 in.64 rear housing would definitely be recommended for a responsive 200rwkws application.
  24. hypergear
    For power and response on RB20det SS1 or SS1.5 .64 is perfect and made for that engine. Those two are highly recommended over high flowing. Alternatively yes we can also high flow the stock turbocharger to be responsive which will be maxing around 200rwkws mark.

    Some update from tuner Toshi. This is the first result from our updated highflow profile, Which has a set of customized wheels. quoted from Toshi's thread: R33 Hypergear R33 hiflow turbo, Z32 ecu nistune 241kw at 15psi Looks like its out of injectors, at 20psi it is expected another 20~25kws gain. I'm not too concert about peek power, however quite pleased with its boosting behavior. In which it did manage to hold straight to red line without tapering.
