    Little update: This is a from a scrapped blown Ford XR6 turbo that we've rebuilt from scratch with a ATR45 core. Its fitted back on to a Auto XR6 (edit: NA+T) 4L with 3500 convert. Car made 295.5rwkws on 11psi with Caltex E65. Looking back from where we first started, my dynosheet pile is about the same height as a Nissan skyline engine manual and it will keep on getting thicker. Any way, ATR43G3 is back on the drawing board for the 4th time, I'm hopping of gain better response while not losing the consistency, top end power or peek torque.

    Its actually cheaper making the T67 alike setup as there is not need spending timing in making all those bolton adaptors as well as internal gate setup. Like we only charge $1000 for the internal gated ATR43G3 units.

    The G2 is only a small turbo. Also Its more of the factory exhaust manifold restricting flow so the power figure is well kept around / under 300rwkws mark. Probably not worth investing a turbo that pushes beyond that unless its going to on a high mount ext gated setup, and I'm pretty sure all the current ATR43G3s has no issues making 340rwkws+ on it. I'm considering of going for a high mount manifold with ext gate once there are nothing left to improve using factory setup. How ever that will not reflect the power figure of those without the same setup.

    Great to hear, You car finally made power . The G2 unit is made for about 250rwkws mark the max I managed to get out of it was 267rwkws and that was with plenty of boost. It did turn out to be a tuning related matter which I was suspecting from the very start. The dyno dynamic's hub reading depending on their software, there was only 2kws variance in readings from local roller dyno vs Status hub dyno. I found readings from roller dynos seems to be affected from the quality of tyre used as well as how tight or firm the car was strapped down. Hub dyno gives more accurate comparison in terms of RPM VS Power VS Torque VS Boost. How ever if the true reading on your hubs is 350rwhp then I would probably stick with that. Any way, you can also ways go back for a dyno run on a roller dyno other then hyper-drives to see if power curve and figure varies. Or pump in more boost.

    Great news the Adaptronic ECU. It worked beautifully today, and the car is very smooth to drive. Every thing worked out great, no glitches with their software, pretty easy interface, it worked on both AFM and MAP, but the MAP sensor is lot easier to tune. No head aces at all, Its perfect. The car made 247rwkws at 17psi with the SS1 High flow. Full boost of 19psi by 3400RPM on 9 sec dyno ramp. Its brilliant to drive on road. Regarding to the ECU I'm unable (not allowed) to retail it alone for under the RRP. How ever I can offer a generous amount of discount on total price if its purchased with any of our turbochargers or high flow services. I'll announce the discountable amount when ready. Also big thanks to Trent, whom is a great tuner and have offered great customer care for this service. Above tune was done free of cost at his own time following earlier unsuccessful Nistune Z32 ecu attempt. With the GTR high flows, I don't believe they are going to be responsive. They are better for top end. Like I would definitely recommend to use a big Single turbo over the twins.

    The plugin ECU series fits into stock ECU casing. which is more stealth then Z32 ECUs. lol. It cost more for this aftermarket casing, as I'm selling my ECU with nistune chip. It supports Both AFM and MAP so you can keep afm if required. I think no AFM is great as its lot easier to setup the intake pipe, you save money from buying the AFM, and there is one less part could go wrong.
  7. hypergear
    I think its an excellent thing to get rid of AFM. Map sensor can be accurately tuned, I see how it goes tomorrow. Had a play with the software it appears that it can run either MAP sensor or AFM.

    SS2 maxed at 320rwkws, the average was 315rwkws. But the power curve was more linear while this one had more mid range. The Adaptronic ECU have turned up today. I've ordered the E420D basic: This ecu comes with a large chunks of looms. It is slightly cheaper. and the Plug in RB25det ecu with metal casing. Both of them has built in 4 bar map sensor (no afm yea~), they comes with software, and data cable. I will be trailing the plugin ecu tomorrow, will post feedbacks and results when done, hopefully every thing goes well. Ps. Did any one get a error message of: [#10151] An unknown error occurred when posting on this thread?

    The light blue with most of power is with gate controller the rest are not. 25psi peak then bleed to 20psi is about where its "happy". The SS2 in original housing reaches 20psi about 3800RPMs, its not as responsive but made more power. So there is a trade off between power and response. Also notice the torque curve, of how its very wide spread that makes the strong and hard pull feel towards red line. By the way this turbo on the test car is for sale with a discount. PM me if you are interested. This is a hill climb competition footage sent in from one of our customer's S14 using ATR28G3 (268rwkws from memory) in Switzerland. enjoy

    ^^ Above high flows should produce around 320HP each or about 520HP as a twin. Also I've made a new housing for the SS-2, This housing is using a circular tube exhaust tunnel while the original SS-2 runs a trapezoidal tunnel. It peeked 286.8rwkws @ 20psi and made 20psi by 3500RPMs. 9 sec dyno ramp, 98 fuel. Its got a pretty smooth power delivery on road, it made the power very easily and didn't get hot either. The SSPU is touch bit more responsive, while this one had a bit more top end. The difference in drivability is I could feel the beat of the engine with the SS2 as power and torque unleashes, like a powerful small V8 feel, while the SS1PU just goes WAHAAAA.. and I'm skiting. But either way both of them are in my favorites.
  11. hypergear
    This is for people whom wanted to see the timing and fuel map for the SS1.5, SSPU is 3 degrees more advanced in ignition.
  12. hypergear
    yes that what we do every day. need the housing and turbo as the rear needs to be exact not only where the exducer is but also the profile runs along the blade. then that should work.
  13. hypergear
    lol. won't work. the clearance should be 20 thou this looks like 500 times more then that. You need to sleeve the bore, then re-machine the housing to suit your wheel.
  14. hypergear
    Use the SS1PU. thats is the perfect turbo for the job. and don't need much boost either
  15. hypergear
    Actually all you need is the FNT turbine setup. that get rid of the flat spot down low, and the G3 accelerate very violently through out rev range with that mod on 20psi. Ask Pat to give you a rid.

    They are coming along fine. I'm still making up the final decisions of the wheel parameters. I want to machine a tinny 60mm comp wheel that can blow out the equivalent of a 71mm cast wheel. That would be crazy to drive with the SS-1's turbine combination. Should get very noticeable difference even on factory setup. Unmarked sketches of the new wheel design. The SS1.5 and SS1PU is now commercially available. We will need 1 extra working days to machine any of the billet wheeled turbos. Price of the SS2 and SS1PU listed is based on a building of a single unit from a block of steel, Their prices fluctuates depending on the No. of orders we get, so PM for their prices if interested as you might be able to get a 10~15% discount.

    Sorry I've decided to build you a brand new turbine housing using bigger wastegate assembly and gate controller. You should have the pack tomorrow or Monday. Also I've purchased adaptronic plug in and piggy pack ecus for testing, I will give a discount on the ECU for all of our customers whom is or have purchased our turbocharger or high flow services, if they works well on my test cars. So R33 GTST owners now can have a good and reliable ECU option for under $1000. Any way this is the ATR43SS-1.5 model. I didn't install a wastegate controller on the testing unit so I ended up with a boost drop, that also lead to drop in power and torque. The controller will be integrated for one more run. 9 sec ramp Here's the fun part. This turbo is made to have similar top end as the original SS-1 but with more torque. The SS-1's torque feels quite smooth and linear, while this one gives this explosion of torque as soon as the paddle is stepped in. It sky rockets 510Mn of torque by 3900RPMs, put that on road it skits in 3rd gear acceleration. Seriously need to control the car with my right foot, but this is very fun to drive. Above behavior is also found in the SS1PU, except the PU version is 2x times magnified (that turbo is crazy to drive on road).

    On another thought its a good thing. Because Trent stopped you from dumpping thounsands of dollars in trouble shooting and headaces. Toshi is comming to melbourne for remap you can just get that for $500. Or I can supply you a adaptronic ecu for $1000.
  19. hypergear
    We are taking dealer ship with adaptronic ecus that run on Map sensors. Cost abit more but you save from the donor ecu, and Z32 AFM assembly. so works out to be about the same . I will speak to trent on Thursday to see whats the most best option within the budget, and will post up prices, all of our customers will receive a discount on those ECUs. You can put up your Z32 ecu and nistune chip on ebay. I'm pretty sure some one will buy that package from you.
  20. hypergear
    You will be surprised.
  21. hypergear
    I have both on 2x R33s at moment.
  22. hypergear
    They didn't work properly on my cars, the ECUs on them are fine. I don't want to discuss those issues publically, and I believe Nistune is working towards solving those glitches in their systems.
  23. hypergear
    They will be $880 each inc GST, Match porting is additional $150.
  24. hypergear
    Well, looking forward to see you guys making some thing work Properly with R33 GTSTs in the near future. Update: This is for a set of GTR turbos that we've asked to match port their housings and manifolds then do a high flow. We will be using ATR43G1 profiles in those with FNT turbine modifications, They are expected to make some where close to 350awkws at full capacity as a twin on 98 fuel. Photos in comparison: Those are photo of stock GTR manifolds: Photo of the pair that we've ported: Photo of factory turbine housings: Turbine housings we've match ported: Profiled turbine housing to suit larger turbine wheel: Machined and enlarged wastegate port:
  25. hypergear
    Sounds normal for a standard R33 turbine housing. To4E's wheels won't be able to blow that much air out of a small housing. To get 270rwkws you will need a much bigger rear housing with a more free flow wheel assembly.
