    Installing the injectors today and found after the cam change the VCT is no longer working. So this result is a RB25det with no VCT. Try to diagnose the problem at moment.

    I got a ATR45 sitting around that came out of my test car which you can swap for trail, that turbo is made as a XR6BA replacement so works identically to a 3582 and maxed out at 445rwkws on E85 externally gated. It will bolt up to your current setup so nothing needs to be modified apart from two silicon hoses. PM if interested.

    Yes indeed, in fact all the guys at tires joint were beating wither this is car has an intercooler or an oversized radiator. I just made 1 person $100 richer today, no one thought this is a turbocharged kia. Ended up with some 225 / 65 / 16 Nitto tires. Still wheel spinning and torque steer all over the places. MT don't make any tires in this size. How ever this result might give a little indication of what the SS1.5 would do on a SR20det motor, knowing the .64 might be a little chockish, this is running a .86 FNT rear with a 66mm compressor. We were been able to add an additional 5 degrees of timing compare to what it was in the .64 rear. Because the additional timing down low and up top, we ended up picking up 40kws with out getting additional lag. At about 20psi this turbo would be an idle turbocharger for a SR, with similar response to a Disco.

    That design does creep boost. I've had few people came with it for the internal wastegate machining and porting. The whole wastegate assembly needs to be changed and with the gate ported open. Then weld shut the closure. Or you can use this, ATR28G2 with FNT .64 turbine housing, which has 38mm internal gate as standard. And of course better power and more response compare to the TD05 16G, also cheaper in price.:

    will cost $150 for the machinery work on the comp housing and back plate. I will need a stock housing supplied to do this.

    I'm running the 275 on 9.5 inches wheels in 17 inches. You can get them to fit. By the way, I've found a local company whom's happy to produce the braided oil lines at a much cheaper price. as well as the quantity that we are producing. I'm happy to deduce $100 off all High flow jobs as we as none special priced listed items. Means your high flow job is now $860, and SS1PU/SS2 is $1350 all including oil lines.

    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.
  9. hypergear
    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.
  10. hypergear
    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.
  14. 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?
  15. 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.
  16. 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.
  17. hypergear
    Any 2.5L Rb25det here?
  18. 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.
  19. 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.
  20. 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.
  21. hypergear
    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.
  22. hypergear
    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.
