Can the 2530's be rebuilt ? I've got a set here, but the bearings are making a noise so I swapped them for '5's

Sort of, they dont rebuild as such, them they just replace the entire chra which is around £500 each turbo iirc

The hks chras may not be available anymore, maybe a stock garret one would work.

GBP500 to rebuild? I think maybe can get a good condition used for that price in japan?
I have seen some going for JPY80000 each.. they looked decent from the photos..
The problem is we can never be sure how good the condition will be..

Don't beat yourself up over a GT2530 just get a new spec -5 they are great turbos!
Hahahah... i am waiting to replace my engine, so i am still considering my options..
How do I tell the difference between the new -5s and the older -5s?
Nope. HKS made the 2530 kits in single turbo SR20,RB20/25 versions in addition to the twin RB26 version - all different exhaust housings/downpipe flanges.
Thanks for the information AlexJ!

I bought mine as refurbished units.

TBH I'd happily swap them for the latest -9s but the cost of pulling them off and remapping etc means it's a waste of time.

Need one with the response of a GTSS (-9), but with a little bit more top end.
Thats exactly what I'd want, would like slightly more top end but not at the expense of the response of GT-SS.

Surely by now there is the technology to create this.

I'm sure there is. But its in the form of a single. Companys don't bother with these little twins anymore.... apart from the said HKS, which are old tech.

Do the GT-SS offer this over the -7s?

You would have to go the bespoke route. New spec -5 are an improvement and seem to spool up a few hundred rpm earlier. Add to that a agressive profile billet wheel and improve that further.

FRRACER,

i was doing some more looking, and it seems that garrett's newer turbos has the GTX prefix.
Is there a GTX model that is similar to the GT2860RS?

Unfortunately I can't see a single coming on as smoothly as my GT-SS, which means I'd be more likely to break traction in my 260Z.

Might give a small single a go in a year or two if I get bored, and try and to control the power curve with some clever ECU settings.
