Apparently, my brand new GTSSs are f*^%ed...

[kjansch]

So, the endless saga of woes with my car continues. Any of you who've read this thread - 2.6 or 2.8? will know the history.

Suffice to say that the car's still not fixed - it's in bits on the floor of a tuner's at present and there it seems it's destined to remain, unless I get my chequebook out, yet, a - f*&^ing - gain...

I had hoped that she'd be ready in time for the CATDT trip to the 'Ring in October, but I've just been told by the tuner that, in addition to everything else (which we'd previously agreed we'd fix as a result of the bottom end failure), my turbos, my BRAND NEW, GTSS turbos, are shagged.

I've been told that it's possible to get them refurbished (re-cored), rather than having to buy a whole new set; so, is it a good idea, and if so, what sort of money should I be looking at? Does £1,100 sound reasonable?

[kjansch]

If I'm going to have to spend at least £1,100 on fixing my GTSSs (which I loved for their responsiveness when my car was a 2.6L) - should I perhaps consider another turbo setup instead, bearing in mind that I've gone to 2.8L dispalcement with this rebuild?

I suspect that I'd go with Garrett (for cost effectiveness). Your thoughts would be good...

Here's a reminder of the spec they'd be going onto:

HKS Step 1 kit (2.8L)
ACL bearings
Apexi induction kit
Apexi Power FC
HKS Hardpipe kite
ATS Carbon twin plate clutch, standard flywheel
Double capacity alloy radiator
Granador Racing Titan GD 771R exhaust
Greddy Profec B II boost controller
Grex oil cooler & remote filter mount
GTROC earthing kit
HKS GTSS turbos & strengthened actuators - shagged
HKS turbo elbows
Large bore stainless down-pipes
NGK iridium racing plugs
Nismo slave cylinder
Nismo AFMs
Nismo low temp thermostat
Sard 700cc injectors
Sard 280l/h fuel pump
Sard racing catalyst
Splitfire coilpacks
Tomei HICAS lock kit
Jun oil pump
Tomei poncams, type B 260 degree 9.15 lift
Tomei strengthened head bolts
Tomei metal gaskets all round - skimmed & pressure tested head
Tomei strengthened timing belt
Torque split controller
Trust sump extension
Defi EGT guage
Defi boost guage

surely the GTSSs will be too small for the 2.8, 2860-5s would be great for response and have a chunk more power at top end...

and you can get them for 1k new.....so may work out better and sell on the "shagged" GTSS to soften the blow...

Ditto with above so how did your new ss's knacker?

[kjansch]

So, if I'm used to GTSS on 2.6, how would 2860 -5s on 2.8 feel? Would the extra displacement make up for the slower response of the larger turbos, or would I notice a "laggy" feel all of a sudden?

Any idea where?

Bottom end failure - apparently they've sucked in all sorts of junk and shagged the bearings.

Thanks: I'll bear them in mind for when I have more time; anyone know of somewhere that might have them in stock in the UK?

If I have to wait for them to be shipped I'll definately miss the CATDT 'ring trip!

[Abbey M/S]

Sure we can supply pretty quickly.

Ok guys, I need help making a quick decision if I'm going to get to the 'ring in October:

Bearing in mind that I like quick response, and I'm running (or will be shortly) 2.8 with all the supporting mods, but that I'm unlikely to run anything more than 600, what would you do from these three options - and WHY?


1. Pay £1,100 to get my GTSSs re-cored

2. Buy some 2860 -7s

3. Buy some 2860 -5s

Oh, and, am I right in thinking this is the correct model number for the 5s - (Garrett GT2860R 707160-5) - and that these are equivalent to HKS 2530s?

[stealth]

Sell yours for recon and buy some others if you need it done fast .

Or try and work out who's fault it is that it all went tits up and sort it out with the Tuner (better option).

Hope you get it done in time anyway.

[moleman]

Bloody Hell, not having much luck mate.

I'm don't know about the -7 or -5 stuff, but 2530s or equivalent would be ideal on a 2.8 I reckon. Easy 600 and a lot of torque.

Can't see why it would cost £1100 to rebuild your GTss. Abbey got my N1s rebuilt for about £450.

Be a massive shame if you miss the 'Ring.

The rebuild cost all depends on how shagged they really are - I've spoken to Turbo Dynamics, who've said that it could cost up to £500 +vat each if they need re-coring, or, it could just be a simple clean up job, and so very much cheaper. The £1,100 was what I was told by Gary - he says that he never bothers with rebuilding turbos, as they often fail after rebuilding, and that he only recommends re-coring as a result. I've been down to GT Art to inspect them personally, and it turns out that only one of them is showing serious signs of damage. One spins perfectly, freely and without any hint of abrasiveness, whereas the other has a stuttery "rough" feel when you turn the spindle.

So, I recon that in actual fact I could get away with replacing, or repairing one, and using the other: trouble is I doubt it could be done in time for the trip in October

That lead me to conclude that I should buy another set, probably 2860 -5s, and then get my GTSSs sorted out by Turbo Dynamics and sell them on. I think I could probably make back the cost of the 2860s when I sell the GTSSs.

What do you think?

[donk_316]

1100 to rebuild turbos? Thats like $2400... you can get a new set for that price.

Not in the UK you can't!

New 2860 -5s cost £1,500
New GTSSs cost £2,100

So, I've sent an email off to PSI Supply, who seem to be able to do 2860s for around £1,000 (although, with shipping, and with UK import duty... )
