    It looks like an OP6.

    New video to share. This is Rb25det G3 high flow result tuned by Garage 7 running on E85 fuel. car made 330rwkws.

    If its an R33 GTST I recommending using Adaptronic plug in ecu instead of Nistune and Z32 AFM. We can give an bondal discount The Return flow cooler kit will be a limitation, if you are targeting 250rwkws thats fine, but for 300rwkws you will need a proper front mount cooler kit. I have personally tested PWR 600x300x79mm and thats the best performer I have used so far. For injectors, I would avoid ebay Jecs. Nismo 550cc and Deschwerks worked better. or ID1000 injectors with aftermarket fuel rail if u want E85.

    Yes, but no results yet. BB delivers better throttle response in general, but not much of power increase. EXTG is definitely worth it. more power, better torque, and better boost control.

    Yes, stock internals, factory cams, just bolton mods, customers car. The neo motors are very solid. The highest figures I've seen using the same turbo stock engine was 421rwkws on 26psi. that engine run fine till rebuilt a year later.

    ATR45SAT CBB turbo 45mm Gate on stock exhaust manifold 4 inches induction pipe, 600x300x100mm FMIC, 3.5 inches exhaust. Pretty things up: E85 fuel with 24psi and 400rwkws. I pushed 431rwkws out of stock cams. Anything bigger then that you can use Tomei Pon cams, car lost 300rpm of response after cam install, managed 490rwkws.

    To keep factory look I can high flow your stock turbo, that makes a responsive 270rwkws on pump fuel, or I can put an stock r33 turbo's comp cover onto a ATR43SAT turbocharger that makes upto 300rwkws on P98 fuel. You will need an 3 inches metal induction pipe to do this. Back at Chequered Tuning today with Adaptronic ecu installed, VCT came back life and picked up 500RPM of response. That PWR cooler however is turning out to be an expansive disappointment showing almost the same pressure drop as the HKS return flow. Factory induction pipe was sucking shut on boost. I will use this cooler for one more dyno season with a Normal ATR43SAT turbo plus a 4 inches hard induction pipe for a comparison run to my earlier result with a FMIC kit. Boost curve shown differences with VCT engagement.

    This is the pressure drop test based on a Trust return flow cooler. Turbo is an ATR43SS1PU, working with RB25det Neo. The end results are all similar. GW2: We will be using the latest Adaptronic Modular ECUs, and will post results after tune. ATR45SS is a big turbo that made 490rwkws on my R33 and cracked 521rwkws on a Ford FG. This turbo do make big power but not that responsive on a Rb25det. Unless you meant ATR45SAT. This one makes up to 400rwkws on E85 with reasonably good drive ability working with Rb25det engine.

    Spent a day installing an newly purchased PWR Vertical cooler that is made for an R34 GTT, it is currently available on PWR's website. Installation wasn't as straight forward as hopped but easier then most of FMIC kits. A quick walk through for anyone that might be interested, the A/C fan needs to be removed for this cooler to fit, and the fan bracket had to be cut short. The hood lock needs to be grind down that secures to the top bracket of the cooler. Passenger side front reo bar had to be filled down missing the intercooler inlet, and the bottom mount matched up to where the radiator supports are. Overall we spent around 4 hours getting everything fit up nicely. Car's yet to be dyno tuned, but does feel slightly laggier compare to the HKS return flow kit that was originally installed. Hopefully it solves the boost drop problem and make few more KWs.

    Stock inlet manifold is capable of making up to 500rwkws with e85 fuel. Those turbos has oil restrictors built in, in usual cases u will not need external restrictor.

    The GTX76 mm is best working externally gated, I believe it is too big to be carried with an 60mm GT30 turbine wheel internally gated. In many cases you probably won't notice much of a power differences running this turbine setup internally gated on pump fuel with a GT71mm GT76mm GTX71mm and GTX76mm except the bigger wheels are comparatively laggier. The best way of taking advantages of the extra compressor flow would be running an external gate to your factory exhaust manifold.

    I haven't personally used Plaszamaman coolers I can't comment. But PWR 600x300x79mm worked very well.

    There has been quite a number of updates applied in terms of wheels, housings and bearings in recent years so we will be starting another R34 GTT modification project, it will used in the development of our SS Ceramic ball bearing series turbochargers. Car is a 2000 model with 80,000KM on the clock, bought from an mature enthusiast whom spent quite few coins at it with: Split fire coil packs 700cc injectors (Bosch?) PFC ECU + Z32 AFM 3 inches Xfroce Varax exhaust Koyo radiator High flowed OP6 turbo (appeared to be an old XTR model) Walbro 255 fuel pump NPC Heavy duty clutch HKS return flow cooler kit. Setup on the dyno for the first time, after few power pulls the turbo started to make some funny noises and we stopped it at 226rwkws at 11psi, Peeked 14psi at 4000RPM. Other issue worth mentioning is VCT. Using factory ECU/many aftermarket plugins, VCT solenoid produces a very distinctive "click" activation sound on throttle opening. PFC activates it in gear, so you should hear it clutched in 1st and a tap on the throttle. Mine is not clicking, later diagnostics have revealed signal output problems from the ECU. If VCT is not activated, there will be a lose in boost response by roughly 500RPM, and I found VCT problems frequently occurring with customers using old PFC plugins. I have re-high flowed the OP6 turbocharger using one of our ATR43SS2 ceramic ball bearing cores: Further dyno shown an improvement in response of 600RPM while a 27kws increase in power. 253rwkws @ 15psi we had some boost taper issues on the dyno, and MAP comparison have once again shown a flow restriction caused by a return flow cooler. Boost pressure before cooler: 22psi, after: 15psi, pressure drop: 7PSI The plan before my next dyno run is to trail PWR's vertical flow cooler as they do make one that bolt on to an R34 GTT and will be replacing the PFC with the latest Adaptronic Modular R34 plugin ECU.

    Back to back on the dyno measuring 4th gear paddle to the metal, there isn't that much of a visual differences to the curves. Take everyday road driving with partial throttle acceleration the differences are very noticeable.

    For up to 300rwkws region a brand new ATR43G3SAT turbo is recommended. ATR43G3SAT bush bearing, internally gated, P98 result based on a R33 Rb25det engine:

    U can use something like above to make similar effect. I've made this for Boost performance's 2JZ None VVTI Chaser, Car pulled 9.9Secs in a worked Auto. Apparently made 2psi differences at 3500RPM. I found this type of vale worked better on a VCT Rb25det motor.

    Go to See Havoc Fabrications for a proper stainless bolt on induction pipe.

    First run with Brand new Ceramic ball bearing T4 print ATR44SS prototype hit the dyno this afternoon. Car made 406rwkws @ 22psi, Pump 98 fuel. full boost by 4000RPM. Stock 2JZGTE, sorry not an RB this time.

    Just repaired a blown Borgwarner EFR with no exhaust wheel. Luckily the compressor wheel is undamaged. It has been fitted onto one of our ATR CBB cores with a custom grind turbine wheel to suit the original turbine housing profile. Looking to match original power figure before turbo failure, hopefully with a bit more torque through mid range.
  20. hypergear
    For a budget 500HP, you can just external gate from the factory exhaust manifold (do not remove pulse divider) and run our high flow on E85 fuel.

    Valve float: it gives this M shape dyno reading I personally use Supertec valve spring kit: http://www.digi-hardware.com/photos/head/springs.jpg

    What sort of power figure are you chasing for? Been an OP6, we can just high flow your stock turbo that can support up to 290rwkws on pump fuel. In terms of engine supporting mods. This is what I've done to my R34 that have made decent power: - Adaptronic ECU- 1000CC ID injectors- 3 inches turbo back exhaust- Walbro 470L/H Fuel pump- 3 inches induction pipe- Split fire coil packs- PWR 600x300x81mm intercooler

    Some video footage from Last weeks Victoria Time attack at Philip Island GrandPix. ATR45SAT Turbocharger Powered Top Stage S14 SR20det (400rwkws @28psi, E85 fuel). Taking first in Modified class. Driven by John Richardson

    You probably don't want to port it. I tried it years ago and It added heaps of lag.

    Highflow results to update: Unopened R33 Rb25DET HyperGears 21U G3 high flow internally gated 600x300x76mm cooler kit. 1000cc ID injectors, walbro 470 fuel pump Apexi power fc 3 inches Turboback exhaust 20psi @ 3500RPM, 291rwkws E85 fuel
