    Yes that was the manifold he made for my car. I still have it. Its better then stock, how ever still no match for the high mount manifold that he makes.

    It was a kunt to fit I spent 2x days on it: making sure every thing is all flat and surfaced. The oil port on the turbocharger get folded under the manifold that needs special fittings. Position of the turbocharger held is only a inch above the oil drain port. That was a real kunt trying to customize a drain adaptor and pipe that doesn't kink and that short. Turbocharger and all related bits needs to be fitted on to the manifold before bolting it up to the head. And then I found the comp housing is hitting against the engine mount. So I ripped every thing out and bought brae high mount manifold. Life has never been easier. The HKS stuff when on ebay. bidding from $1.

    The G3 and SS2 do produce noticeably strong mid to top range power with better transition response since they are built with a small turbine and the advantage of a reasonably large housing. This turbocharger is good for a budget built. Like all other ATR, with very high external gate high mount potentials. I will be working on the SL2 10cm based turbochargers next week. releasing 2 new models.

    The HKS low mount is very difficult to fit. The Garrett .60 or .70 housing with a 4inch induction will sit against the engine mount. Not mentioning every thing else had to be custom made to suit. Since doing the manifold and gate rout, better off getting a local hand made high mount item.

    Some further updates. Since the majority of market is pushing for a cheap and cheaper option, I've managed to find and import some 21U copied turbine housings from China. Crazily machinery costs is only 1/30th of what my accumulation is in Australia. So here it is, a Cheap turbocharger that produces decent power and response. The ATR43G3.5. Since 1/3 of the turbo and machinery work is done overseas. I can manage to squeeze the price down to only $850 including braided oil feeding line. Dyno trailed today with very successful outcomes. It managed to archive 355rwkws, maxing out at 22psi. Far as pricing concern, this makes the lowest $/KW ratio turbocharger with added benefit of Rb2x bolton. It is pretty aggressive on road. expecting to see some where around the 320rwkws used as a internally gated turbo on pump 98. I've already mentioned the limit of stock exhaust manifold, so its up to the end user to sort out their own manifold and other supporting mods.

    Bring us your stock turbocharger if you don't mind lag on the little RB20. I will be interested to see when it runs out of puff on the new infinity high flow profiles.
  7. hypergear
    $800 including oil line. Depending on when can get it tuned, will be looking towards a weekish mark. Also this high flow is made to aim 400rwkws mark, So it might not be very responsive.
  8. hypergear
    I'm having issues sourcing a Dead op6 turbo at the price I like to buy. I'm happy to do a 400rwkws infinity high flow for a R34 customer at $800 including oil feeding line and actuator. In which I will use it for a dyno run before sending it off. Post up or PM if interested.
  9. hypergear
    Yes can build in bush or balls. The bearing setup used with this SS2.5 High flow is in ball bearing. Depending on the bush bearing setup. We make our own oversized collars and bearings and they would last longer then most of roller setup under high thrust load. They worked fine on 30psi
  10. hypergear
    Its good for highflowing. makes 280rwkws on purple and 300rwkws+ with E85 internally gated. Not so useful if you've bought this for a Rb25det.
  11. hypergear
    Pretty good result for a high kmed auto. Run it on 18psi it should be making around the 260rwkws mark. Back on the Infinity (name of this project) high flow project: This high flow project is a cheap alternative to a high powered turbocharger, Its cheaper to modify a turbine wheel then building a brand new .82 turbine housing. I will be making some external gate adaptors for them too. End result is pretty good, not only it made the power this response is better then any turbochargers with its power range. So instead of high mounting ebay special or a expansive alternative, this is making the same amount of power within rev limit with heaps better response. Plus its also a stock replacement works fine internally gated. Here is a comparison against my SL20.5G and Std SL20G from results earlier. The margins has been 100% lined up. Faded: Yellow, pink = ATRSL20.5 Green, blue = STD SL20G Highlighted: SS2.5 21U high flow How ever the SS2/G3's turbine wheel with the .82b FNT turbine housing is still much more efficient, that makes heaps better torque and power power even thou the run the same compressor wheel. The VNT stuff is work in progress mainly because its too expansive for any one to buy and own. So i'm looking for cheap alternative for it to work.
  12. hypergear
    JPC only used a stock .63 turbine housing, and the rest is all of some thing else. Plus the car had large cams, engine work, plus a 3L bottom so it will be pretty hard to get their results unless I have the exact same setup. Plus I'm not going to run 30psi + of boost. I need to get my hand on a OP6 turbine housing first, I will try to do this 400rwkws high flow based on the factory Hitachi compressor and turbine housings then see what it does on the dyno.
  13. hypergear
    SS1PU has better response in lower gear even thou the looks very similar. The SS2.5 in side the high flow has much larger turbine wheel in compensate for the size of housing. SS2.5 did make more mid - top end power.
  14. hypergear
    The wastegate only opens a sip some thing like 5 degrees to drop boost, plus they all equipped with a massive 38mm gate. So it only needs to open very little for boost control. If it works on the dyno then it will work on road. I don't see any down side of doing such.
  15. hypergear
    Thanks for the feedback. I will work on the pricing and management to make latest technology more affordable. For some customers whom has the boost drop issues with internal gate. We normally loaded our actuators by 3mms in tension, It appears the exhaust pressure varies depending on mods as well as the day temp, which results in a boost drop of certain degree. We had a SS1PU on the dyno yesterday, it had 4psi drop using a 14psi actuator which run from 20psi to 16psi. That actuator had no pre-load as the customer had to drive his car for a period of time before tuning. in attempt to gain mid range boost, I overly loading the actuator spring by roughly 17mm. It looked at on photo below: Car has managed to gain 3psi in upper revs leaving only 1psi of drop making 280rwkws on the dot. This problem can be fixed either by using a very stiff actuator or over load a softer actuator. advantage of the soft actuator is it allow low and high boost control working with a electric boost controller.

    I will do a special deal at $1160 including oil line. it might not be as responsive in the OP6 rear, how ever that should be reaching close to 370rwkws mark once setup on a proper manifold and gate. Also releasing one more profile for the 21U turbine housing is the G3.5 This turbocharger is also a specific high flow built chra. it should produce bit more then the SS2.5. Hopefully be seeing towards 350rwkws mark. Its been pretty responsive using the 21U turbine housing. Few other news is that I've managed to source some R33 copy turbine housings. That will help saving lot of costs building them here. I will pass on the savings and work out a cheaper alternative to high flows very soon.
  17. hypergear
    Standard high flow can get you a very responsive 250rwkws, while the SS2.5 or G3.5 can make more power will be laggy in the op6 rear housing. I can do a special deal on the evaluation price of the G3.5. PM for further details.
  18. hypergear
    Op6 should net around 370rwkws mark in this combination. I think I can get it close to 400rwkws with a different set of compressor profile. How ever it will be much laggier. By the way, the SS2.5 is a CHRA made only for RB high flows, specially the 21U R33 housings. Won't be great used in normal housings. I can also build the SS2.5 using the latest G3 comp wheel. Which will not add any costs to the standard profile while producing identical amount of power.
  19. hypergear
    LoL that was a SS2 back up turbo in case any thing goes wrong.
  20. hypergear
    Yes the ATR43SS1 result of it on a Rb20det is on our site. SS1 billet version is updated version with better response. How ever I don't have a result of it based on a Rb25det.
  21. hypergear
    Video footage from today. Surprisingly after multiple runs, the turbine housing or manifold did not turn red or overly heated. I guess this is the highest no. that a highflowed r33 turbocharger in factory housings has ever archived. This evaluation is pretty successful. It how ever do cost $200 more then factory high flow option, for the extra work required on modifying standard turbine housing, as well as the high pressure actuator and SS2 billet compressor wheel. I believe it is good for some where around the 280rwkws when used on stock manifold, internally gated on pump 98 fuel with good supporting mods and tune.

    Here is the dyno reading: Boost: Super responsive. Makes That about the same response as the SS1PU. Makes 17psi by 3500RPMs and about 100kws by 3000. I will upload the videos shortly.

    22psi on e85 and shinnnnnnnnnning Dou dou dou dou I will upload all the papers when I get a computer tonight. Doing it with my phone and it sucks.
  25. hypergear
    A high flowed stock turbo like above deserves to be high mounted and externally gated. Even thou it doesn't looks pretty. but 342rwkws out of a high flowed R33 turbocharger (not r34 op6) is a brilliant result. And the response is amazing. Trent just finished tuning. I will upload more data and video footages when I get a scanner. For now:
