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.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
