I bet it will still be working 6 months from now, unlike any other turbo he has had :D

It's probably not fair for you to comment on the past turbos because Garrett aren't the ones necessarily at fault. Bolting on a different brand is not necessarily going to fix the problem. Garrett don't make shit. They have a 0.1% failure rate due to manufacturing faults. It all comes down to what has happened to them while they are on the car or after something else has gone wrong. The first two were shortly after engine failures. The next two had massive chunks missing from the compressor blades prior to them failing.

At any rate, Noel is already having a fairly hard time dealing with it so I'm just going to give him as much support as he needs to get it on the track again.

He certainly doesn't deserve to have so many let go. I'm just trying to point out that it's not always cut and dry like most ppl think.

The quiet hint a few pages back didn't work so I'll leave these links here...

T04s are relatively inexpensive and reliable on any other car, but Christine eats them for lunch. Before you come to the conclusion that sleeve bearing turbos are inferior, let's not forget the three GT35Rs Christine (Sierra Sierra EVO) destroyed previously when the engine was making less power

Dunno what we're gonna do yet mate. I do know we are pulling the fresh engine out to see if any damage occurred as a result. Here's hoping for the best.

You cant be serious? I finally check back and read this..

Hope all is well, any updates?

Deadly serious. Busted the bearing cage and sent the turbine flying into the exhaust.

On a more positive note the engine survived it with minor abrasions. New bearings and a clean out and we're good to go.

Waiting to hear what Garrett have to offer us before we make the next step

Do you know the cause?

well from what we can gather:

3L bottom end + GT3582R with 0.82A/R rear housing

750deg runner temps but possibly exceeding 950 degrees in the housing due to the size restriction. The bearing cage and everything around it was blue all the way to the comp side apparently.

Considering an offer from Garrett but if he moves to the BW turbos it will be a 0.92A/R but better than that it will be a T4 footprint which means more gas flow and less heat. Unfortunately it means more hp which we don't want

I guess its better to have head room HP wise, you could run less boost and more timing and make the same power with less strain?

No other options to control the heat?

I get it, Its hard enough to put the pwer down as it is, More HP would probably make it slower around the track as opposed to faster!

Yeah i get it aswel, just something we dont hear often in here :D

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
