i had my 2510 rebuilt with a garrett cartridge and as close to 2530 spec garrett exhaust wheel.... (not by GCG) had nothing but trouble with noisy bearing sound, they claimed some garrett bearing packs were naturally noisy....sounds like a cop car siren when spooling up

2 cartridges in 3 months and the thing is still noisy as hell.....been 5months and still noisey but still makes good HP so i just gave up on sorting out the bearing whine.

let me know if you have better luck cos i might freight mine over to GCG next time round.

BTW it cost me $700 for rebuild including garrett bearing pack and another $300 for the exh turbine

what causes these things to die? has the turbo in question done loads of work or is it a tune or oil supply issue? I didnt expect to hear about GTRS rebuilds as they are a relatively new model; ie still plenty of many-years-old GT2530's still going hard and strong.

are these turbos designed to constantly and reliably run 1.3 - 1.5 bar all day everyday ...??

can a poor afr tune decrease their life?? like leaning out up top.... if so how?

I'm not sure what has caused this turbo to start blowing smoke. Unfortunately I was silly enough to purchase this second hand (off a forum member) - and I trusted him with the 'condition' of this turbo. Hopefully it is something as simple as the seals needing replacement - because the turbo had bugger all shaft play when I had it installed.

    • Yes...but look at the numbers. There is a tiny tiny fraction of the number of Joules available, compared to what is used/needed. Just because things are "possible" doesn't make them meaningful.
    • Thanks for taking the time to post that ! If anything changes or happens please do update us. 
    • Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.
    • Ok so I have sorted everything with my uniclutch and  i can offer up a bit of feedback and some things that might help others.    I found problems with factory damper line. Weird shit and had trouble with peddle adjustment    I used this https://au.gktech.com/products/r33-gts-t-skyline-braided-clutch-line?_pos=2&_sid=22b01b9b9&_ss=r Also when adjusting peddle leave a bit of play. You can get into a over stroke condition easy.. Make sure you can push the slave forward after adjusting to confirm fluid can return to master then you will need to pump it up heaps…..not sure why but that’s how it is.    last thing the splined adapter is machined perfectly. If your input shaft is old like mine was I would put a bit of valve grinding paste on it and stroke it like a 15 year old. Just to give it a tad more clearance and to better match it to the spline.    reason is on a near flat shift I have had situation where the peddle returns a millisecond after you lift from the clutch. No slip or anything but I reckon this is due to tolerance on the spline being way tighter than stock clutch and binding for a sec. I think this will go away but also my spline was old. Box is old so I guess I should have checked better. It’s a super neat fit.    it feels light as and holds awesome without any noise
