I'm guessing the 2871 would be a more appropriate sizing for 220-250kw and ultimately quicker spooling and response?

Less torque but more consistent over the power band.

Smoother power delivery slightly but holds about the same up to redline!

hey, ive had my NEW hypergear hiflowed turbo on my r33 for 4days..

just sent my stock rear exhaust housing (snail) to the east...

they hypergear fitted a ATR28 G2 core and new front compressor housing(polished!! :thumbsup: ) ..

and a 14psi actuator..

all for $925 including shipping...

done bout 200ish k's...

and its goning well...

still running it in...so yeah..

but seem alot better than stock..

and it boosts alot better too, from what boost levels ive hit....

i would recommend this to any r33 driver that requires a new turbo...

evan if car is fairly stock...e.g: ecu/afm/injectors...

theres a few modifications u gotta do to make it fit..

like the oil feed line...and the inlet & outlet on the compressor housing..

but other than that its worth the upgrade...

Ok here's a initial running in result from a high flow using a ATR28SS. car had boost controller issues so peek boost of 12psi and dropped to 9psi. made 201rwkws with almost identical response to stock Ceramic BB turbo. Car will come back to do a run power tune once done 1000KMs, expecting even better response with about 250rwkws..

RB25Neo, Stock ceramic BB turbo vs ATR28SS. The car was dynoed before turbo upgrade.

could you please provide me with a price, delivery into Adelaide, for a Hypergear ATR28G3(450HP) profile in Ball-Bearing

would like it to be highflowed to the maximum to front / rear housings, to suit a RB25det

cheers, much appreciated

Please check PMs. Also some bad news on the Garrett BB CHRAs. Garrett fliped their whole sale price up by 33% over night on popular CHRA models. lol. So now its going to cost 33% using Garrett GT CHRAs.

i had a tr43 on my rb20det i couldnt adjust the acuator as it was hitting the rear housing of the turbo. so it was boosting to 20psi, apart from that it lasted oh say about 2 weeks befor it shit itself there f*kin shit if your gunna buy a turbo spend the money.

Rowan unless this turbo was made back in 2006 or a similar looks alike this sort of thing do not happen to our TR43s. Our internal gates in them has been specifically designed and tested on RB25s they do not spike, also Our rear housing never hit, They are running the same diameter as a .58 R34 rear housing. and using the exact same diameter comp housing as a S14. There is no chance it will hit.

    • Will have a look at that. I cant see any leaks 
    • Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.
    • Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
    • Hi Everyone I am from West Pennant Hills in NSW. Been too busy until recently to attend to my RB25DET Series 2 engine until recently. I am planning to stick it into the S15 shell at this stage, unless a nice SR20DET turns up... For now, i am going to try and get the RB25 running and working well then decide what gearbox to use. My preference is to retain the SR20DET  6 speed gearbox and tail shaft to retain as much and least modifications as i can avoid. I am an old guy and won't be doing any heavy drifting so i don't need a bullet proof gearbox Does anyone have experience with starting the RB on a stand? I got everything setup as much as I can with the info i can find... endless searching and videos on Youtube I would be great to get some pointers Cheers Songo
    • Hey all, Recently have had my s1 r33 gtr serviced and noticed my coolant reservoir was topped up to the max line. Took the car out for 1 yesterday and noticed today the reservoir is completely empty.  Any ideas? Radiator is full
