Is it this one? https://www.croooober.com/en/item/cparts/00000132/Turbines/11896643/HKS-Etch-KS-GT2535-56T

Yes I think so. Same shop for sure.

Old 2nd hand turbos are a risk. That turbo could be fine, or it could be f**ked. If it's f**ked in a way that you can't tell before you install, then you waste all the money spent on taking the car apart and putting it back together. Doubled, because you have to put the original turbo back on. If it is f**ked in such a way that it dies 10 minutes or 10 weeks down the track, it's the same, but worse, because you could be out on the highway somewhere, stuck in the snow. It's your gamble. You're probably more likely to blow up your original turbo though!

There are many people around the world that can highflow a stocker. If you were in Oz I would have recommended that you contact Hypergear in Melbourne. You could still get a turbo from him, even from Japan. Have a look at their site. There are many options on the site - can be confusing. Just contact them direct if you want to go down that path and need help.

Your right and that is my fear. I have heard of hyper gear, I guess I’m inky concerned of the price being worth it because stock housing isn’t very expensive. I feel like a my lady shopping for shoes lol

Why is that?

i guess it all depends on the availability of the other parts you need to fit the 2535. The one in the link has the oil feed line, but doesn't have the coolant lines, 90 degree elbow or oil drain to make it a bolt on kit. Add the cost of buying these and it doesn't look cheap anymore

And then you don't know if it's in working condition. It looks ok, but any turbo does if you give it a clean!

The other option is the hypergear high flow - which they can supply the donor turbo if needed and send it to you. I'm not sure if you have a R33 or R34 but in theory you could get the exact turbo made to suit your power goals and have it bolt on 100% if there are limited options for fabrication etc

Thanks that was helpful especially when determining costs. I didn’t look at it from that perspective.

Yep I was not suggesting going with the GTRS but I do have one .

The issue is turbine housings , specifically ones that bolt to the standard manifold . Just on this , the std manifold mount flange is a "T3" bolt pattern but it is slightly wider across the two exhaust outlets than a real T3 single outlet port .

The drama with RB25DETs is that GT28 turbines are really a bit small especially if its in a small 0.64 AR GT28 turbine housing . This is exactly the format that HKS made their T3 integral wastegate turbine housing . The plus was that it bolted up and made an easy install but I think that's because it was something more intended for RB20DETs . HKS spec Garrett turbos like GT2530/2535/GTRS (2871R in 52 compressor trim) could be optioned with this turbine housing .

I mentioned recently that we are having the same problems now that we did 15-20 years ago with GT30xx turbos - no T3 flanged integral gate turbine housings except from HKS - ka ching ka ching . These days there are no T3 or T4 turbine housings out for the current Garrett G series turbos which is probably why the market is reluctant to buy them . Ideally something like a G25 or G30 should be ants pants but Vband mount turbine housings are useless to most of us . Geoff at Full Race in the US is pushing for more usable G series turbine housings but things move slowly in Garretts aftermarket section . OE spec turbos to the manufacturers is where their volume sales are .

That aside most people will probably say buy one of Hypergears  turbos or go with something like a Garrett GT3076R or GTX3071R in say a T3 flanged integral wastegate 0.82AR turbine housing . Its been done here a lot and it does work reasonably well .

Cheers from Adrian .
