Rebuild Or Replace Stock Turbo - Who, What And How?

Hi all,

Was hoping for some advice, just lost my ceramic turbine out the exhaust of my stock Series 2 R33 with the RB25DET and who should I get it repaired by, or should I just replace it?

Only got a stock motor with high kays on it... (270k), standard in guard I/C, standard ECU and about 10psi.

Suppose, I must have either hit more boost than that a few times for it to let go, that or I had a bearing let go.

Either way the turbine wheel has gone now and the car lost a lot of power (no really! lol) and the rear seal was weeping a little oil so I had a smoke screen following me at any rev above idle.

Got the car home, without upsetting too many people but I need my daily driver back!

Not interested in rebuilding the motor on this car or making it a high power, just need it back without too many hassles now or in the future. Really want bolt on and am happy to do a bit of work to get it done.

Who can overhaul?

Can I send it somewhere and get a standard overhauled turbo sent to me?

Can I buy a new spool assembly and bolt my bits on them?

What is the most cost effective?

Where do I buy?

Probably don't want to spend heaps but I don't want to buy cheap shit either, will possibly park the car or move it on soon.

Any ideas, who can help me please? Need the car back on the road asap.

I am in Geelong, Victoria not that this will make much difference!

Thanks in advance for any advice.

Hypergear rebuilds them for about 8-900..will be better than it was, have steel wheels probably make a little more power too

or just chase up a S/H unit on the classifieds..for 2-300$

highflow turbos are only as good as the person doing the job. you cant say a highflow will kill your motor with supporting mods.

had one on a SR20 for 3 years seeing 18psi almost daily

with 270k on it, i would source another stock one and fit that. a high flow will kill your motor fast

He is saying that with more boost from a high flow it will kill a high km motor easily... not that the high flows are dodgy....

As for replacing the turbo.. good option with piece of mind is as mentioned get Hypergear to rebuild it, alternatively you can look in the for sale section here for people wrecking or parting out skylines... you can pick up a good condition stock turbo for about 200-300. the only thing is how long will it last again as they are getting quite old now.

think I will chance it and go stock.. if I can find one cheap enough.

wish the car was newish like 12 years ago when I bought it.

nothing like the choices to modify back then, unless you spent up big.

thanks everyone...

I don't know how much you can trust another second hand turbo. In all honestly most cars will have in excess of 150000km, hell even 200000km on them, so you will be buying a turbo just as old as the one you had let go...

Very true, however I think I know why this one let go... so I don't plan on letting that happen again.

Besides, don't go looking for R32 turbos. Try to find as late an R33 one as you can, or an R34 one if possible. Newer, less miles. Also less stress in your application (ie they can be boosted higher before failing when used on an R32, so at standardish boost should last well).

The best option would still be high flowing the stock turbo if you are keeping the car. as most of 2nd hand turbos are at their last legs either way. We replace not just larger steel wheels, but the complete CHRA, its more of getting a brand new turbo back in stock housings.

You do not need to replace the turbo again on engine change or rebuild, it can produce lot more power with better relaibility then stock turbo once upgrades are installed.

      Tein Circuit Master- rebuild worth it?

      By MBS206 · Posted

      If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.

      Best place to order Authetic R32 Parts in Japan

      Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)

      Murphy strikes again! Nothing at all would have gone wrong if you had the tool kit in the car! You'd have just found the clamp loose the next time you went to touch it...

      Blue slip

      By MBS206 · Posted

      I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...

      Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
