Hypergear Turbochargers and High flow Services Development thread


Recommended Posts

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

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.

What would you recommend for a daily driven rb20

Looking for around 220ish kws, response and internal gated?

With normal mods

nistune, EBC, cooler, fuel pump etc

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.

    • So.... when I'm finally getting around to having my power steering leak sorted, now it looks like I've got the same issue most A/T Skylines are having. My A/T light will randomly come on and I'm stuck in 3rd gear until I turn the car off and on again. Only 3 weeks ago I did a complete transmission service: Oil flush + new gasket + new filter. This came out of nowhere!! It wasn't like the car was driven hard. I drove about 3 mins down the road to get fuel and boom!!!  Anyway, I have a few questions and hope you fine people can help me out here. All questions are in red. 1. The solenoids: I was looking at the parts catalogue in Amayama and I could only find the Solenoids as an assembly. https://www.amayama.com/en/part/nissan/319404ax05 I read in another thread that Solenoid A = 31940-4AX02 & Solenoid B = 31940-4AX05 but the Amayama product has only the code of B. Is this the right part? Can anyone who has done the Solenoid changes or seen them confirm if this is the complete set of A & B?   2. Gasket and Filter: I'm not going to try change the solenoids myself because it seems difficult to do in a home garage with just 2 jack stands. I plan to take it to a shop and get it changed. I was also going to buy the transmission sump gasket at the same time so I don't reuse the same gasket. Should I just use the existing gasket as it has only been on the car since OCT 19th? (~3 weeks) Should I be buying a brand-new gasket and a filter? Does this job involve taking the filter out?   Thanks in advance to everyone. It's hard to find a video of someone doing a solenoid change on a R34 so any help you can give answering my remaining questions would make me less stressed.
    • Yea - From what I have seen from the video, the car idles like any R34 lol 50PSI of fuel pressure is hardly super abnormal, the regulator is working because the pressure remains static when the throttle gets revved, i.e pressure remains the same when manifold vaccuum changes. Bigger pumps on stock rails always bumped the pressure in the rail without using an aftermarket regulator to change that. Do you know what your IAC is actually doing? Has there been any data showing the stepper motor % etc? There's no way your idle is actually moving around the way the cluster(s) are indicating. You would hear the difference with the engine RPM flying to 3k and 1k in mere seconds. I'd be checking the wiring to the tacho. What the tacho is telling you and what the engine/ecu is telling you are different things. I assume your ECU doesn't display the spike. So whatever is telling the tacho to be at X rpm is doing something weird. When the going gets insane, you're on the wrong path. You've ruled out plenty of things that are working correctly/aren't the issue. Your idle isn't doing what the tacho is indicating. You have two seperate issues, I don't think they are linked, and the idle seems reasonably okay unless it's stalling which.. well, it hasn't. Troubleshoot the stall if it occurs by figuring out what your IAC is doing vs what it is being told to do.
    • So awesome! I love the RB with the exhaust on display.
    • NO HITS PRICE DROP   ENGINE - $8.5k ONO TRANSMISSION - $1.8k ONO  
    • If it has had a code in the recent past, the code should still be there waiting to be read.
