    Updating result with ATR46SS-1 turbo with a custom T3 .82 rear housing. So the car originally pulled 652rwkws maxing out 3 inches turboback exhaust and current external gate spring: A bleeder pipe added to the front pipe, and stronger actuator spring added to the external gate. Unfortuantely we are reaching the torque limiter of the dyno, so we did a short run in 5th gear. The car have managed to pull 718rwkws @ 37psi on E85 fuel before breaking the gear box.

    I found G30 turbine doesn't have enough turbine to run 900 series compressor wheel, you find G35-900 makes alot more top end. Having said that I can rebuild and hybrid your current 770 that makes more power without too much lag and better reliability. Add: After reading your dyno print. It should not reach shaft speed limitations at 26psi. This usually happens when compressor is fully maxed. When I was conducting bearing threash hold few years back, 54/55mm chra exploded at 38psi while 58/62mm configuration exploded at 41psi. Test conducted based on a built EA888 Gen 3 engine.

    Here's something I've done 10 years ago. Making custom comp wheeled TD06SL2-20G. Not sure if that became the 20rs equivalent 😂 R33 GTST, Rb25det with forged pistons and valve springs. Turbo was in 10CM rear, Externally gated run on E85 fuel.

    Hi, on E85 fuel and internal gate, 54mm ATR28SS15 in T2 .64 rear housing will do nicely. I've used BC Step 2 (272dur /12mm) on SR20det for 300rwkws+ applications

    We usually charge 600 to do both including supplying of new flaper valves and busing assembly. Those housing materials are pretty hard, takes a good couple of hours to do.

    Hi, G3 profile with Rb25det turbo housings will be fine for around 270rwkws on Pump 98 fuel internally gated. I can supply donor housings if interested. To make the power you will need 3 inches metal induction pipe, 600x300x100mm front mount cooler, at least 3 inches turbo back exhaust, programmable ecu, along with injectors, fuel pump, you've got.

    N55 is a single turbo, that high flow service linked above including ball bearing convetion and something similar to a G33-900 wheel set with line kit. N54 are two little singles like a Rb26DETT. They make good power after high flowing, I usually build them to gtx2860 in specs. Wastegate bushing can be repaired. To machine four housings, two new cores and two wastegate flapper / bushing mods, its not any cheaper however.

    Updating result, This is from our latest ATR45SS-3 model, Its made for 100bhp applications. Same car as above. It managed to pull 636rwkws at 34psi. Drive ability wise, car hits 300rwkws by 4K and 450rwkws with 1014Mn of torque by 4250 RPM. Pretty good to drive with crazy amount of mid range torque. Run against ATR43SS-3ProR turbo from earlier. r33636rwkwsmusic2good1min.mp4

    R33's back on the dyno again for development work, testing an new 6 blade 55mm prototype turbine. Using ATR43SS3ProR turbo for back to back test. New turbine shown a slightly laggier curve, but picked up 16kws on same boost pressure with smoother mid / top range power and torque band. Final run of 509 rwkws @ 25psi Engine Specs: Rb25det head with forged Rb30det bottom Forged pistons and con-rod Upgraded Valve springs HKS step 1, 256/ 264 drop in cams Fuel system: 1650cc Bosch fuel injectors Two 460L fuel pumps ECU: Haltech ECU Turbo side: Hypergear ATR43SS-3 ProR Turbocharger 6 boost high mount exhaust manifold Turbosmart 50mm external gates Hub Dyno Tune: Chequeredtuning Victoria

    I've included some data from current model ATR43SS-2 turbo. Its very different to the 2019 version mentioned by Hardsteppa, and makes a lot more power. On this R33 Rb25det, it sit on 25psi by 4K and 372rwkws, that was on pump 98 fuel externally gated, They do around the 400rwkws on E85 fuel. Turbo can sounds like a Jet, I've attached a short vid from a recent dyno tuning:

    Updating result: R33’s back at Chequered tuning for with another of my in-house built specials. Car had no other changes apart from the turbocharger, we managed to get: 516rwkws @ 26psi 569rwkws @ 29psi 606rwkws @ 30psi 642rwkws @ 34psi Turbo’s holding boost with pretty consistent gain per additional PSI of pressure is added. Unfortunately my 3 bars Haltech Map sensor (vacuum is a bar) was very maxed, be back on the dyno to max out this turbo once new sensor arrives. Pretty successful day over all.

    Updating this thread as some of yous would have seen on FB. Not about turbos this time, but a piece of information for people seeking the Rb2530det rout. I've attached results of my built Rb25det with Kelford cams Vs my built Rb30det with HKS cams, making it a reasonable comparison of what Rb25det Vs Rb30det is like. Both engines had identical setups, E85 fuel, made the same power, while the Rb30det was 1300RPM better in response, more power every where and 137Mn of extra torque. I’ve also attached result of differences HKS cams made in comparison to stock Rb25det cams on the Rb2530det engine.

    Sharing a pretty interesting result from a Rb20DET with Rb25det Neo Vct cams. Turbo's one of our ATR43-G2 BB model for RB20det in T3 .63 rear housing. Car managed to pull a pretty responsive 321rwkws on E85 fuel externally gated. Engine's in a Ford AU . Pretty interesting eposide to watch:

    Yes. worse then my 25 year sold stock coilpacks. Throw them away.

    Regarding to Rb20det highflows or builds from earlier discussion, they runs a smaller turbine and and compressor then a RB25det turbos. Can build it into a OP6 it would work similar to a HKS2530 with a modern wheel set for more power. Its not a bad choice. Sharing another result. This is an ATR43SS2 on Pump 98 fuel making a pretty responsive 355rwkws @ 20psi.

    ATR43SS2 is a brand new turbo that is capable of making more power. Ball bearing option is highly recommended. It is also highly recommended working with our externally gated turbine housing kit.

    We've done 411awkws with crazy amount of mid range using factory engine and auto. The power figure were made on E85 fuel, but it will not have issues making 300rwkws on P98.
