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.

    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
    • I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt 
    • So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm. 
    • Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
