Hi,

It sounds like one of my HKS GT-SS turbos is failing ( getting the low siren noise when accelerating ). They would not have many K's on them and was considering just buying a single replacement turbo . They don't appear to make GT-SS turbos themselves anymore so I would have to get the Garrett GT2859R's. I don't really want to upgrade turbos at this stage as I'd be up for another $2500 for a tune alone.

A single turbo is $1400 vs a new kit at about $2,500 for the Garrett GT2859R kit.

What do you guys think? I think it would be best just to replace the single with a GT2859R.

Thanks,

Pen

Was in the same circumstance last year.  I decided to remove ($750), refurbish ($1500) and refit ($750) my twins.  To build a single set up (turbo, manifold, wastegate, fabricated IC piping, dump-pipe, exhaust, tune) you'd be lucky to have change from $15,000.  There are obvious benefits, but it is an exercise on the wallet.

If you are looking to stay with your current set-up, rebuild the turbos rather than simply replace them with a second hand kit, this is a much surer way to ensure they won't fail again.  Used turbos hate coming off a car and sitting on a shelf, no matter the mileage.

Where did you get the turbos rebuilt?

FOr a cheaper option, I was looking at just replacing a single turbo from my HKS GT-SS set with the equivalent Garrett - GT2859R. I can get a GT2859R from GCG for $1400 new ( https://gcg.com.au/petrol-performance/performance-4/turbochargers-garrett-t-gt-series/garrett-gt2859r-turbocharger-aka-gtr-9-s-detail ) and use my HKS actuator. That would be keeping the other turbo (provided it is in good condition). So hopefully saving on some labour as well by just replacing the damaged turbo.
Do you think I should just replace both - it would be $2500 for a new 2xGt2859r kit? I could go second hand to probably save a little.

I got my twins rebuilt and balanced at Precision Turbochargers in Wetherill Park, NSW - https://precisionturbos.com.au/.

Replacing 1 faulty turbo and replacing it with another 'similar' turbo would cause headaches down the track.

1. GT-SS and 2859-9s are slightly different in spec and will blow differently.

2. You leave yourself open with the other GT-SS being prone to failure, thus setting you up for another remove and replace bill which is the costly part of a low-mount twin configuration

3. for the price of 1 new, you could refurbish both GT-SS', which i still think is the most reliable and cost effective option.  While you're replacing you could opt to replace the water & oil lines with a supertec braided kit over the hardlines which are prone to threading upon removal - https://www.facebook.com/supertecracing/posts/1753715698048181

Buy 2 new ones that are the same as what you have. While you are there get a full gasket kit. Thats your surest and cheapest way to fix it.

Or go single, change both turbos and within a few years one of the turbos will fail again with a bit of boost.

Where's @Piggaz ? Lol

Yeah 10k later lol

 

Or 3k or less to keep current setup. GTRs are suppose to have twins @Dose Pipe Sutututu thats what makes it a real gtr?

Says the guy who binned his gay sex twins and went single 

Thanks for the help guys.

I can get this braided oil & water kit for $143.10 here would that be equivalent to the supertec braided kit?

I was looking at just buying another set of turbos Here . Rebuilding was going to cost only a little less.

I should also buy the turbo gasket kit too here .

Anything else to add to the shopping list?

I wouldnt buy a cheap hose kit. After going single turbo i probably spent closer 1k for braided hoses and fittings by the time it was all said and done.

Your gasket kit comes with new copper washers so as long as the stock lines are good id reuse those.

Would also get a new exhaust gasket (block to manifolds).

This is a great time to do dump pipes if you havent already. Hpi/tomei seem to be the go. Aparently split dumps are the devil lol.

I think you'll find that GTSS and 2859Rs have cartridges with the same part number so the compressors should be the same . Turbine is just a cropped NS111 .

Some time back Garrett wouldn't sell the cartridge on its own . If your sick turbo has a good compressor and housing you should be able to get it rebuilt . From memory Garrett did a turbo called GT2854R which uses the same turbine as the GTSS/GT2859R . Someone who can get that cartridge should be able to use your compressor and housing on that to create the same thing - provided you comp and housing are good .

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
