    Well, the test cars wasn't built with budget in mind so it has reasonably good parts. There are many variances to consider depending on setup just like not all 3076s make 300rwkws. How ever our turbochargers are always been improved for better. Later models has better compressor / turbine efficiency, response, boost control and power to boost ratio. Many members using our turbocharger have archived expected results. Just noticed the expected level of performance for OP is 300/330AWKWs, in which by comparing results, 4WD skylines are 12% in power behind RWD skylines. That means some thing at 370rwkws on E85. That figure is very hard to archive using stock exhaust manifold internally gated. Unless its been externally gated from the factory manifold or using a high mount setup, regardless this figure is way out of what a 20G in either external or internal gated can deliver. If it has to be a TD based turbocharger I strongly recommend our SLSS2 in 10cm or a SS2 in .82 rear, both externally gated. In terms of our high flows, bolton turbos and other turbos might be, more specifically to Rb25det will out perform the kando items with much longer life span. Plus we don't charge $1600+ unless you are looking at SS Alpha series. Usual high flows starts from $850 and the bolt on SS2s are for $1450 all including braided oil line.

    I guess it is up to the limitation of what factory exhaust manifold can flow. How ever I think I can match or beat your result of 336rwkws by high flowing a standard R33 turbocharger using factory housings internally gated with better response perhaps. Can't stop trying harder for new heights

    lucky you've mentioned it, I didn't take a note that it is for a Rb20det. The current R33 profile would be able to support roughly 250rwkws while older profile would be more responsive maxing towards 230rwkws. So would you prefer power or response? Some updated photo of the SS2 M35 Stagea high flow with our latest SS2 compressor wheel, and latest SS2's turbine wheel which is 3.5mms larger in diameter to the older version with a 2 degrees difference in blade radius. Please note the internal gate is to be enlarged which didn't take place when this photos were taken. And of course never stop trying. Here is a newer version of a ATR43 prototype, aimed at high 300rwkws with optimum response. It is for Mr Hovic's drift car.

    Well 3071 is very laggy on my SR. 180sx doesn't have VCT so it won't be much better then mine. Getting things to work on the SR is much harder then on the RB. The current VNT turbine system have only made the car hitting 1psi much quicker, at 5% light throttle I can hit 1 psi. from 1psi to 20psi still takes for ever, there for, no end result differences. Doing some evaluation on SS15 on .64 rear at moment and it drives nicely. So further evaluations to be conducted at this stage. One of my FiveO motor sports's 1200 injector gave up the ghost last week after 5 dyno runs, which is abit disappointing. getting replacement installed shortly for SS Alpha bolton series evaluations soon.

    Nothing wrong with current turbo, it is big enough for 400rwkws+ on E85. The power tread seems to be very similar to my KIA sportage, it is a high comp 10:1 motor how ever. Didn't like timing but still took more then the OP's R34. Fitted a couple of turbochargers on it, and larger turbochargers do result in a slight power increase every time. The new turbocharger is for the XR6 BA engines, bigger in both larger compressor and turbine. I think it will do 530rwkws on my car. I don't have much time on it currently. But following the turbo size to power tread, it should be sitting at 350~370rwkws mark on OP's car. It is not the right way, how ever is a possibly solution on getting more HP.

    Any one suggesting "Biggerrrrr" turbo?
  7. hypergear
    Manifold studs are M10, and from memory the end that goes into the manifold is M12x1.5 and the end that connects to the turbocharger is M12x1.25. With the dump pipe studs, if using a ATR43xx bolton turbocharger, the one above the internal gate flapper has to bekept short. or it might be fouling against the gate. Preferably just a 20mm bolt

    By looking at the curve its not making much power for the setup or been responsive in todays standard. Housings are tinny for this engine is, which makes compressor flow strongly relaying on the external gate. That would be making the turbine side red hot, probably starts to pin after a couple of dyno runs and it had to be pulled off the dyno. It needs a much larger housings with more civilized wheel combinations.

    Want to swap your car with mine? Drive off with 490rwkws not cent needs to be send on. Few years a ago I remembered a customer had similar issue and it turned out to be two teeth out on the cam belt. I've also seen some interesting and strange results with those cheap NZ manifolds. It might be some thing to look at by trailing using factory exhaust manifold.

    Well. There has been many G3 and SS series been built through the year, the spec of the turbocharger varies, the internal gate assembly is matched to suit the application its designed for. Which not necessarily made for 14psi that can be rised using a EBC to reach 24psi. Relating to the latest incident, it turned out the dump pipe bolts used are too long that fouled against the internal wastegate flapper. So its no longer spiking at uncontrollable boost level. Regardless, if a turbocharger is made for a internally gated 280~300rwkws application then it is obvious that it will be running in between 18~20psi of boost. If this turbocharger comes with a 20psi assembly then lowering boost level by change in actuator will not result in significant differences in the minimum boost level archived. I can not use a 14psi internal gate assembly to hold 20psi nor using a 20psi internal gate assembly to run 14psi. In which the assembly it self has been setup for this purpose. To clear the intention of purpose I do ask a lot of questions before proceeding in building any turbochargers. Below is a demonstration of two different internal wastegate assemblies: Purple is made for 14psi, made to run 20psi. Blue is made for 20psi, did every thing possible to run at minimum boost level. Orange is made for 20psi, run at 20psi.

    Its been sent out few days ago. should be with you very shortly if not yet arrived.
  13. hypergear
    hahahahaha. No man. KIA's taking 15 degrees happily. Well RB25det pistons are lower in compression to Neo pistons any way. Should have helped in knocking prevention. hopefully the engine is all good.
  14. hypergear
    ok. hope every thing gets sorted shortly.
  15. hypergear
    Did that actually make 400rwkws on stock manifold?
  16. hypergear
    Guided at 4000 / 4500 / 5000RPMs. Per description on the boost curve sheet: 19psi @ 4079RPMs, 25psi @ 4218. There was a split silicon hose that was unnoticed, affecting boost response. This turbocharger is going back to dyno again in two weeks time using my modified stock exhaust manifold expecting to hit full boost by 4000RPMs. It drives reasonably well on road, has a 3582's top end without the lag.

    I can upgrade it to the current SS2 for $250 if you prefer, and ask M35scotty to do the external gated rear housing mod. How ever I have picked up a lot more power from externally gating through factory exhaust manifold, it is preferred if you can do the same. See if Scotty can do that for you.

    Yes, we did get the Adaptronic tuned running. The internally gated VNT turbocharger didn't work according to plan, but I did get plenty of data for further research work. Regardless, VNT internally gated system is proven working, and have made a difference in turbocharger's response: If I have time finishing off the newer prototype, it will be trailed again on the 29th.

    Well any thing bigger will need to work with a even larger compressor wheel which will be looking at the SS3 and SS4 series in .82 rear. How ever those wheels are too large for the factory compressor housing so as far as high flow concern the 376rwkws E85 result is about the limit for now. And here is a quick peak of a brand new ATR28SS1.5 Alpha prototype, which took me a weeks of spare time to complete. Note this is the internally gated version. It is currently a bolton turbocharger for SR20det motors. After a little bit of driving around it is definitely more responsive then the SS1, even the CHRA configuration is larger. There are alot of reasons on paper that it will not work properly, and I will end up with very little power plus either a massive boost creep or a massive boost tapper. And also many reasons it should work as pressure drop by any exist will result a pressure drop off all exist. This is like the argument that we've had earlier with few members on where the external gate should be fit thread, of pressure V flow. If it does work then by using this method we should be able to knock some lag out of GTR motors that runs on large twins. Dyno tune tomorrow morning. Hopefully the working theory proves its ground.

    I will need the factory actautor, which I can set it up in a way to hold 20psi. But if you don't have one then we can supply an high pressure actuator for $100 additional with fitting bracket.
  22. hypergear
    All the hoses from My self are restrictor free they are good to use.
  23. hypergear
    Mine is for sale, R33 GTST, and it has made a useless 490rwkws (wheel spin in every gear with 275 Micky Thompson ETs), not sure if that is "big powered" enough If you've already got R34 then get: ID 1000 injectors Adaptronic ecu Stock manifold with external gate mod or Brae High mount with external gate. Our high flowed factory turbocharger E85 That should reach towards 350rwkws.
  24. hypergear
    This is Important: I've just had a customer brought a set of Kando's oil feeding line kit in dummying up with his newly high flowed R33 turbocharger. I've noticed the benjo bolt supplied with the oil feeding line has a 1mm oil restrictor in it. That must be drilled out to at least 3mms. I definitely recommending of buying our own oil feeding line to work with our turbochargers. How ever if you've got the Kando / Ebay oil line kit, Please make sure all fittings and the hose has a inner diameter of at least 3mms before using them on any of our journal bearing turbochargers.

    Not really. quite opposite actually. They start with one turbocharger and the other turbocharger weaks up later. I want mine to start up as a twin with only the smaller turbocharger generates boost, when the larger turbocharger in pre-spool (or lag) state. Probably an ATR43SS1 with a ATR43SS5. So in this setup once certain boost level reaches, take 20psi for instance, which on paper appears to be @ 2800RPMs for the SS1, It will carry the engine out to 4500RPMs in which the larger turbocharger also makes 20psi. At that point the smaller turbocharger goes to sleep. and the bigger turbocharger carries on. There will be a couple of switches involved, how ever If every thing works out right, I shouldn't have any dips in power curve and it will behave like a tinny turbocharger makes 490rwkws.
