I did some SR stuff in 2014. if you go back to page 456 and read from there, that contain alots of SR20det's developments. On page 1, search SR20, and I have listed pages that contain SR20dets developments and results.

RB25 Neo, Drifting, getting response up
hypergear replied to Lopin18's topic in Engines & Forced Induction
I assume you are running external gate. I have a recent case of a turbocharger that we've built, that pulled over 530rwhp E85 ( similar to pump 105) @21psi full boost by 4000RPM out of a stock R33 Rb25det. With an Neo head and slightly larger capacity you should see even better response. details of the build is at: https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/?page=604 -
Another result to share, this time from one of our high flowed R33 GTST 21U Turbochargers externally gated on a built Rb25det engine. Car made a super responsive of 330rwkws @20psi on E85. Full boost by 3500RPM with very wide power band. Forged R33 Rb25det engine, ported engine head. HyperGear High flowed R33 GTST turbocharger SpeedTek exhaust manifold Turbosmart 45mm external gate ID2200 Injectors + Twin Bosche 044 pump Programmable ecu 3 inches turbo back exhaust Tuned at Chequered Tuning Looking forward to see it perform at Vic drift Round 3.

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.
-
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.
-
Assume its on a welly built SR with a good free flow setup, you will match result of Top stages S14 listed above.

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.

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.
-
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.
-
With the bush bearing recommendation was referring to the Rb25det 21U G2 high flow. Mainly because the housings are small enough to generate a very responsive out come, BB or not doesn't make much differences. But for anything else BB is recommended.
-
Super-Drager: Anti surge sleeve is ready but I haven't had too much time on it in further developments as I'm trying to get everyone's order completed for the time been. Action Dan: For a super responsive 300rwkws E85 turbo I recommend our ATR28SS15 BB version. Result taken from a track car with built engine with 272/12 cams. No VCT Pattey21: R33 G2 profile is recommended to run in a bush bearing setup, the configuration I use is already very responsive the way it is, which hits 20psi just before 3500RPM. I Can make it bb if you prefer.

Some videos to share from Victoria Time attack, we've taken 3rd in street class and first in the fast RWD series. Car is above, R33 GTST stock engine running one of our high flowed OP6 R34 turbocharger making 328rwkws internally gated on E85 fuel.

Rb20 Turbo Upgrade, All Dyno Results

Check for intake side leaks, make sure actuator is correctly shut and preloaded, Set cam gears to 0 degrees. This is result form my test car, unfortunately it had a broken piston in cyc 6 and could not stop miss firing up top. It made 215rwkws, 20psi by 4000RPM.

Some vids from Vicdrift round 1. We've taken first, car's powered by one of our ATR43G3SAT turbochargers, pulling 360rwkws on E85 fuel externally gated stock engine.

Big thanks for Lithium for the information above. Some video footages from Cam Martins car last week. R33 GTST powered by one of our ATR45SAT turbocharger making 320rwkws Pump externally gated.

Hi, the Car's running 22psi to produce results above. With that FFP modifications, one of my tuners did mention it feeds CYC 5 and 6 more air then the rest causing them to run lean. I don't have personal experiences with them, so I can't comment.
