    From an engineer point of view. This is because the metal used in modern comp housing alloy forging is not hardened. What we see is the metal melted during high speed machining process and stuck to cutters and housing, that can be touched up fair easily. In most cases there is a secondary process performed on lathe that removes all the debris, deburr sharp corners and round off thin edges, but how fine it needs to be is up to the manufacture. The comp housings forged during the early 90s are better quality, materials is hardened, they don't stick on tools, can be turned at moderate speed and comes out smooth after profile cutter. Modern CNC machines has much higher chunk speed, soft alloy can now be profiled to a mirror finish, so majority of castings today are no longer treated.

    The ATR43SS2 BB is a capable of much higher power levels then the high flow while not been any laggier. I guess if you have external gate E85 plans for up to 440rwkws E85 the SS2 will do, and this turbo works in both internal or external gate (obviously much high power externally gated). or if your goal is roughly 300rwkws and won't be thinking of of any thing much higher, then high flowed turbo will do fine.

    ATR43SS-2 billet ball bearing turbo, most people tend to use them as a low mount bolt on. It works fine supporting 300rwkws on P98, Once given E85 and external gate it pulled 442rwkws with 280rwkws @ 4000RPM. This is a super fun daily or track car.

    ATR43SS2 BB in .63 internally gated or We can high flow your stock turbo to make around 280rwkws and that be super responsive also. This is an latest result of our latest profile of an 21U high flow on a stock engined R33 GTST with big cooler, Greddy inlet manifold, and 3.5 inches turbo back exhaust. 362rwkws @ 22psi E85 fuel.

    Some latest data about twin scroll exhaust manifold vs single scroll exhaust manifold. Still running the same turbo, now making 440rwkws @ 27psi while close to 500RPM more responsive. :

    6.9 Sec with 188 miles quarter run from last week, from one of our rebuilt, high flowed and ball bearing converted BW S400 turbochargers powering a built 4G63 Evo engine running about 55psi.

    There are differences between compression testers. I've used two testers on my built engine and they varied 50psi in reading. As long as the compression between cylinders are even then the engine is likely to be good.
  11. hypergear
    Its been a while since my last update, car had some engines issues as I found its lack of power and response compared to other R34s I’ve owned. Comp test reveal a 50psi drop at CYC 4 compare to other 5. I’ve had the engine stripped with intention of restoring OE compression, using a set of Nitto pistons, con rods, oil pump gears and valve springs. The rebuilt engine ended up with slight lower compression then standard but all even, it is making more power and been trouble free so far. I’m keeping the stock cams for now, it will be upgraded at later stages.

    It will definitely not be as responsive as a 2860. That is too small for a rb25det. New G3 high flow has the same response as the older version with more mod range and top end power. It is still very responsive for daily or track.
  13. hypergear
    The highest result out of the G2 profile lot was from Dr.Drift's personal R33 back in 2010. That pulled 253rwkws on pump 98 fuel.
  14. hypergear
    The car needs a big front mount cooler, Go for Aero flow 600x300x100mm for a good budget cooler. Also the G2 model is a factory replacement, to get more power you will need the G3 or bigger profiles.

    Another 400rwkws Rb25det powered by one of our ATR45SAT turbochargers, externally gated E85 fuel. Tuned by JEM.

    Little video to share about Jason Ferron's drifting session at Calder park few weeks ago. Video's been put together by the Drift Junkie Andrew Sparrow, do check out their Youtube channels about he's R33 GTST build. Jasons's car is powered by one of our high flowed R33 GTST turbochargers making around 310rwkws on E85 fuel.

    Product update for ATR43 RB bolt on series with 3 inches dump pipe suited for Rb25det and Rb30ET. Available using ATR / SS series as well as Garrett GT / GTX CHRA. Housing's available in T3 .63 and .82, internal gated with 38mm port. Externally gated housings can also be supplied. More details are on our site, or simply send us a PM. Inside the dump pipe assembly.

    Video footage of last weeks South Australia Time attack. Our sponsored vehicle is Topstage's carbon S14. 2015 built ceramic ball bearing ATR45SAT turbocharger survived engine failures, melted exhaust manifold, and this time fire from hydraulics fluid leakage. Still managed to take first in rear wheel drive class.

    New version has a more free flow turbine wheel.
  20. hypergear
    Yes that is on E85. I don't have result of this version on 98 yet. it would be sitting pretty close to 300rwkws on that car.

    Further development in R33 21U high flowed turbochargers. Latest model made 342rwkws fItted to an unopened R33 Rb25det engine as a bolton turbo with FMIC, 3 inches metal intake pipe, 3.5 inches turbo back exhaust, fuel system and programmable ecu.

    In simple terms, stock engine and basic supporting mods on pump 98 fuel. -9 can get you around 300awkws responsively, -5 can get you around 360awkws but its abit laggy.
  24. hypergear
    Thats in .82 rear housing. Power curve is in response to boost curve, unfortunately I don't have a boost reading. I've dynoed way more powerful cars on that particular dyno there's not issues with it. The only time I had similar power outline was a boost spike. Might be a delay in ext gate response, boost spiked around 4000RPM, then dropped back to norm. Could be waste gate springs are too hard, gate is jammed, hoses connecting to the external gate is too long or parameters in the EBC not 100%.

    Just a quick note, the ATR45SAT you had was a 5 years old unit, current model is different, result has been updated to dyno section. More developments are underway. And result to share: GTX3076R Gen 2 maxed on a built Rb25det Neo on 26psi of boost, externally gated on E85 fuel.
