Any updates on the SR motor of yours Stao? my brother is looking one for his 180sx, tossing between one of yours, and a 3071.

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.

So, my r33 turbo is getting highflowed at the moment, (thanks Stao!) what are peoples thoughts on what power it will make on an rb20det on 98?

Usual support mods, nistune, z32, 800cc sards, return flow cooler, 3 inch turbo back, metal intake pipe

Have seen results of previous highflows, but not results on the current profile on a RB20.

Cheers

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.

Updating some results:

SLSS2 as some have already seen. Final result of 356rwkws @ 23psi factory engine stock cams E85 fuel.

Brae manifold, Externally gated.

21U high flow on a R34 Skyline, final result of 266rwkws @ 17psi Pump 98 fuel. Going with high pressure actuator for 20psi, hopefully be seeing close to 300rwkws soon.

ATR43SS2 factory Bolton Turbocharger on a stock Rb25det powered R32 with No VCT. Final result of 328rwkws @ 21psi E85 fuel.

My brothers evo booked in for a tune next week

Stao fitted a slss2 chra to his evo 9 turbo

Hoping for 280+awkw on 25-27psi

Dives nicely on current tune gate crackes at very low 4000rpm untuned won't let it go over 20psi on 18psi actuator

I would be interested to see the graph as I have the same highflow in my evo7, just waiting for the engine builder to finish his work.

Stao I'm curious to hear what you think of compressor housing size and power levels , where you think the cut off points are for the 0.60 T04B , the 0.50 and 0.60 T04Es . The T04S is usually as big as most go and I'm curious to hear how much difference you think there is between it and the 0.60 T04E .

Also can you supply a T3 spacer plate in 15 to 20mm because I can't easily get one , GCG advertise a 20mm one but they don't have them and don't know when ...

I have their longer studs and I want the thicker spacer to cover any future updates , do once do right .

It's no secret that I don't like the S covers mainly because they look bigger even if it's not much over the T04E port shrouded one . I just can't get my head around using a supposedly 700 hp comp housing on a 4-500 hp compressor .

There are a few less common compressor housings floating around like the 0.70 AR T04B and there may even be a T04S 0.60 AR . I remember Brett telling me years back about a 2" outlet comp housing they used as an upgrade to the XR6Ts T04E one so there must be a few odd ones out there .

Thanks Stao , cheers Adrian .

Hey Stao,

Was there boost controller issues on the 21U highflow on 17psi?

I'm going to be going E85 on my R34 in the near future with the same high-flow and will only be looking for a high boost setting of around 18psi

Just dynoed the atr28ss15 on my sr. Made 270rwkws on pump with 22.5psi at 4000rpms. Will upload sheets and attend questions when I get back home.

What turbo you going now gtscott

Cashed in on the MTQ GTX sale, now have a GTX3071 and will be installing over the next couple of weeks.

Picking it up tonight to start rigging it up.

    • So for the wide band is a Bosch 4.9 correct for the Link G4+ along with a Can bus? Just get the Link gear or is generic ok too? Eg here: LINK LINK DIGITAL WIDEBAND CAN MODULE WITH BOSCH 4.9 SENSOR : KYP Performance House  
    • Bit difficult to follow. Have a look below and see what the standard R32 layout was like. Note there was a restrictor in place immediately before "turbocharged pressure control solenoid" that, if removed, magically got you 1 bar boost.
    • I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators. 
    • Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?
