I bought my 2535 cheap second hand on the basis of rebuilding it

The cartridge was dry, and after oiling it and letting it sit for a while with oil in the cartridge I took it to a turbo shop and they said it all felt fine

Been on for 18 months at 255kw and still going great

Anywhere that sells garret turbos should be able to rebuild it if required

Except that they don't rebuild Garrett ball bearing cartridges.

There's info on turbobygarrett.com about a service program, but it's relevant only to the US market.

If the unit referred to by OP has excessive end play, the solution is to replace the entire cartridge.

If you really want a fresh HKS GT2530 make sure the compressor wheel isn't damaged and preferably the compressor housing too .

If the one you're considering is for an RB20 or 25 it will have an integral wastegate T3 flanged turbine housing so it can make any GT28BB based turbo bolt to your factory exhaust manifold . Having said that there are limits to what sort of power you can get from even the best GT28xxR turbo particularly on an RB25DET .

If you expect an easy 260+ RWKW on petrol you probably really need a GT30 based turbo in a Garrett . GT3076R or GTX3071R would get you there easily with the supporting mods . GT2530s and similar are better suited to mild 2L 4s .

Thanks for everyone's help.

How does the GTX 3071R perform on a rb 20 and rb 25?

 

I have found only alittle info about them for those engines.

ball bearing GT2530 for an RB26, receipt says $980. was a couple of years ago now.

 

no details on receipt, but i believe it was a full reco with a new CHRA., cleaned housings and wheels etc. looked new when i got it back.

    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around with a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
    • Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.
