    Sounds like too much back presure. need a larger housing, or larger turbine wheel or stronger actuator.
  2. hypergear
    That can be compensated by machining out the internals of the factory turbine housing making a larger blow tunnel while using an extra large turbine wheel to compensate. Not sure to what extend thou.

    I'm aiming to crack 300rwkws with a stock 21U R33 housings on pump 98. It felt abit too responsive as some thing maxing 300rwkws, can't wait to see how it goes once tuned. Its a brae manifold. a duplication of my ebay SS manifold that cracked using steel pipe. its apparantly an expansive one time job that I haven't fully evaluate it yet. I've also got an HKS low mount cast manifold fully surfaced with T3x bolt pattern. comes with HKS 38mm gate for $1200. PM if interested

    Turbo's installed today: Looking pretty stock ? Initial test drive, it builds up boost very quickly. Dyno tune due in soon.
  5. hypergear
    That should be fine. Please check email for order details. Thanks

    SS1PU makes around very responsive 260rwkw mark running 18~20psi. 22psi max it out at 280rwkws which is the most this turbo can do internally gated. This turbo has no issues handeling boost. For the GTiR rebuild, $400 covers: 360 degrees thrust bearing, bush bearing, collars, seals, sand blasting, balancing and assembly. Drop the turbo in when ready. I will need to pull it part to give you an accurate quote.

    assume the wheels, shaft, bearings, and housings are re-useable. That will cost you $400. If every thing are gone and only housings are good then its not suitable for rebuilding. That will cost you $800 which is high flowing to 2860rs specifications. So the worst case scenario will cost $800.

    That was the older profile, the current profiles are once again totally different just like every thing else we do. They also made to work with stock oil feeding line, we no longer supply braided lines for that model.
  9. hypergear
    That was for rb25, m35 turbo high flow profile is different, won't be laggy at all.
  10. hypergear
    Since I have to do it, I rather over doing it. Yes can be make in to 3 inches.
  11. hypergear
    Nope, the comp inducer is larger then the 2.5 inch inlet they had there. Had nothing left to clamp hose on after machining. lol

    Some Modifications that I've done to a stockie R33 21U turbo: 4inch inlet adaptor with SS3 comp wheel: Looks all sort of stock I guess. Would be awsome if I can crack 300rwkws with it internally gated on pump 98.

    I think its more to do with the wastegate gate setup. When Trent did the internal and external gated test, the hug drop in internal gate setup means the turbine is cooping with high exhaust manifold pressure as well as heat after certain rpms. From experiments that I've conducted a large external gate acts as a secondary turbine that carries out compressor flow only when needed. So getting good results from an internally gated setup: Comp flow = turbine flow on the external gate perspective: Comp flow = Turbine flow + External gate flow. As if I run G3 compressor onto a SS1PU's turbine with a large 60mm external gate, I should get the 300rwkws peek power from the G3 while having the 20psi by 3300RPMs response of the SS1PU. I will do some tests on that when I’m over with stockie boltons.
  14. hypergear
    The reason behind that is because your car is running on E85, High mount exhaust manifold and external gate. Run pump 98, internally gated with stock manifold. That power and torque figure will drop significantly after 6000RPM. which is like: There are lot more to think about when building a turbo made to perform on Pump 98 and internally gated. A turbo that can deliver performance internally gated on pump 98, has no issues cracking the extra KWs on external gate with E85.

    Well I enjoy design and building some complicated turbos or forced induction parts. This turbo its a hobby thing, the importance is making a difference, and it is very difficult to make possitive differences, pretty happy with the out come, So this technology is available in building SS2 or SS1PU turbos when needed. The SS1PU is a better turbo then the SS1.5, which I will remove that off the listing.

    93 model R33 GTST Forgied CP pistons, valve springs and stock every thing else. 550cc injectors 600x300x75mm Front mounted cooler Xforce 3inch turbo back exhaust Manual boost controller ATR43G3 Ceramic roller bearing prototype turbo internally gated 4inch intake pipe Nistune Z32 AFM in cooler piping Pump 98 fuel. Car maxed 302rwkws on 19.6psi Video:

    Finally got the hobby turbo tuned today. made 302rwkws just touching 20psi internally gated on pump 98 fuel. Referring to dyno reading it made about 200rpms of difference in response, I'm pretty happy with its out come. Video:
  18. hypergear
    Yes can be done, cost $1700 for both turbos. Also congratulation to customer whom won Vic hill clamb championship. That we built a custom turbo for his SR20det blue bird.
  19. hypergear
    ^^^^ I thought the turbo is comming back for a ss1.5 upsize. The main issues with intake restriction are that it can not supply enough air to the comp wheel, 2ndly that slows down the shaft speed making turbine wheel harder to turn, there for trapping combusted air inside combustion chamber causing detonations. I'm still waiting for bit more feedbacks from couple of evaluation SS2 units at this stage. Will produce them when I have more solid results. For time been, 250~270rwkws mark use the SS1PU and 270~300rwkws mark use the G3. There is also a prototype high flow from R33 21U turbo that Im working on and off for the time been. The goal is to duplicate G3's result while stay in factory turbo shells.
  20. hypergear
    Try this. I managed 315rwkws pump 98 with.
  21. hypergear
    Do you have one laying around? I'm interested of doing a back to back dyno testing using a PU .82 high flow. Would be interested to source some for high flow customers if they work, or at least can find out what they support up to.
  22. hypergear
    not always pin type. You can burn 2x 20thou pin wholes on stock injectors and that turns it into 800cc.
  23. hypergear
    Have tried some thing similar on a Rb25det. compressor runs out of puff up top. Not sure on Rb20dets.
  24. hypergear
    The Rb20det's high flow profile is smaller then what we normally do on RB25det. it can be made bigger, how ever the drivability would turn bad as its missing 0.5L and no VCT enhancing down low. Rb25det would make power lot easier, Rb20dets are generally 20% behind in power.
  25. hypergear
    Where did you get this intake pipe? I need a few my self. In this case not sure if by using high pressure actuator holding more boost uptop would gain abit more kws, but that would be about the limit from high flowing a R32 GTT turbo. That is a tipical high mount ext gated turbo good for running E85 with (above result was on 98). not suitable for high flowing. But let me know if you want to go down that path.
