Most i seen was 266kw from my car 25psi dropping e85 and that was with the larger rear housing .86
Stock bottom end sr but
I would reccomend going the atr28ss2 in bb with .64 rear housing more responsive due to the smaller rear and i made 280kw with this
On a built motor with larger cams and custom exhaust manifold i would see it making 300kw

Action Dan: Yes. the factory exhaust manifold is a restriction and SR needs cams to make power. Plus your usual free flow FMIC, induction and exhaust. 

Ask tao im sure he can arrange that
Most results ar from rbs but usually all in by 4000rpm and there only running t3 single scroll
Twinscroll will help alot hence why evos get away with 300kw turbos but are still responsive

This particular SR20det engine is something built by forcedmotor works 4 years ago. It run one of our ATR45SAT turbo compete and won WTAC Open class in 2016 and is still a current world record holder of the fastest SR on Wakefield. Its on a single T3 scroll manifold running external gate, and that pumped 400rwkws on E85 fuel, 28psi by 4250RPM. Far as I know its just a standard rebuild, no VCT with forged pistons with 264  / 256 Tomei Pro cams. For around 350rwkws mark I will be recommending this turbocharger.

Some results to share, This time is from Justin's drift car running with one of our ATR45SAT ceramic ball bearing turbocharger.

R33 GTST unopened engine.

HyperGear Atr45SAT Ceramic ball bearing turbo

6 boost manifold

Turbosmart 45mm Gate

Ebay 600x300x100 Cooler

ID 1000cc Injectors

460 lph Fuel Pump

3 inches turbo back exhaust

Haltech ECU

E85 fuel

Car made 397rwkws @ 21psi on a conservative tune for stock engine. Should see 420rwkws at full potential.

I would high flow the factory turbocharger using a ball bearing core with a G2 or a SS15 profiled wheel sets. the SS15 is a better choice for power and response. 

For the best result use an Rb25det turbo. For a Ball bearing, billet wheel Ss15 profiled highflow looking at $1500 to complete including oil line.

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
