Turbocharger Rebuild Shop
I had all the information in August, from I thought here. I think the trhead even mentioned 55 trim. But now can't find it, even after spening over an hour looking, and can't even find a place that can rebuild a turbocharger, except one here, but only do high performance.
Anyone know of a shop in Southern California or Phoenix that rebuilds stock turbochargers? I did look into doing it myself, but with my motor skill issue and how many specifications and technicalities, don't want to mess it up. Thank y'all in advance!

When I read this, there are leaps of logic that I am not following and I presume there was info in an earlier thread.
So some questions/observations: 1. You had/have a boost gauge plumbed in. What does it read at steady cruise, and on hard acceleration? 2. Have you checked/cleaned the banjo bolt on the manifold, where the boost sensing line attaches? 3. Are you certain all of the boost sensing line is intact? 4. Have you tried bypassing the overboost protection switch and running the line straight to the ALDA? 5. Are you sure that he U-shaped hose from the air cleaner into the turbo inlet is firmly place? (This is referencing the noise you heard, if that hose is loose and debris gets sucked into the impeller blades, it can make such a noise.) 6. I am having trouble seeing any situation where turbo performance would degrade due to engine heat in the range you describe, 85. Just don't see it. 7. If you want to stay local on the rebuilder, call a big shop that works on highway tractors and other large trucks and ask them if someone local does turbos for them. 8. Rebuild if you want but I would ask if anyone has a good used turbo, first. The turbos on these cars usually are long lived (compared to gas cars). I would buy a used one from another (known, trusted) list member before going the rebuild route. 9. If you want to send it out, these guys have been around since at least the 1980s: Majestic Turbo - Automotive Repairs | Irving, TX . They may be able to ship you a unit on a core/exchange basis. If not, they probably turn around repairs in 24 hrs. 10. If you want to tackle it yourself, Majestic can also probably sell you a "cartridge" that replaces the wear items on the turbo. Check out YouTube, I would be surprised if there aren't lots of videos on that job, given the big interest in turbos these days and the fact the ricer drivers treat them as disposable.

1) 2 - 5p.s.i. and 10p.s.i. W.O.T., in third, up a hill, meaning really working at it. 2) At least twice. 3) Yes. 4) Kind of, as didn't have boost protection when fuse 14 kept blowing. So feel fairly certain, but if you tell me how, can test again. Though also need to fix the gauge. 5) It was not the U that had issues, it was the line going from the manifold to the boost gauge. Everything is intact by the turbocharger, even replaced a missing nut on the flange long while back. 6) At what temperature would this happen? What is causing this change in performance? 7) Good idea! 8) I have a used unit, but paid $40 for it, including a Federal air cleaner I have no use for. Got it as a core, partly so I could have a rebuilt turbocharger and partly to be rid of the A.R.V.. I am one to be prepared, and when the deal presented itself, seized the opportunity. 9 and 10) Really like that company! They will do a diagnoses free of charge, rather than full rebuild even if it doesn't need it! That is saying something! It is up to Dad if he is willing to bother with it, if so, can send it there and have it shipped back here. If not, do what I was planning anyway and sent it out myself when I get there.

I just had the turbo for my 1992 300D rebuilt by G-Pop Shop. They are in Arkansas, but they do top notch work. If you don't mind the car being apart for a week or two while the turbo is off being rebuilt then they are a good choice.

I saw them and looked decent, but seemed more into performance? Mind sharing the cost?

From what I've read in this thread and your other one on the subject, I think your turbo is probably ok. I suspect you're having a fueling issue. When it gets sluggish, try pulling over and opening the fuel cap. If there's a rush of air going in when you do, then it's probably a plugged tank vent.

Any shop that does turbo repairs can do a stock rebuild. Their advertising (like website, etc) will stress the performance end because that is the customer that they have to lure to them. Mine was done at Tim's Turbos in Virginia. Tim does lots of performance work but will just as happily build one back to stock as will most turbo shops. Replacing bearings, checking for cracked impellers, checking and adjusting clearances, etc. is the same regardless of application.
Remember that most turbo shops live by the stock rebuilds from the commercial Diesel trade. The performance end is, for most shops, the fun part. Dan |

Is the boost gauge plumbed in before or after the overboost protection switch? If the turbo is producing boost and not producing smoke out the tailpipe (oil seal issues) then there isn't anything wrong with it, though it's no doubt worn. You must have sufficient fuel being provided to match the volume of air being compressed into the cylinders by the turbocharger. Like Skippy, I suspect you have a fuel issue, not a turbo issue. Try putting another turn into the ALDA. If you don't see any difference, the ALDA adjuster may be broken. It happens from time to time.

I had Pure Turbos do my 300SD's turbocharger. It was about $375. They're in Oceanside, CA.
One of the guys on here (Hit Man X) referred me to them. I'm happy with the results. http://www.pureturbos.com/store/

Thank y'all for all the replies!
Falling asleep, so will do a better reply later... Will say reducing the A.L.D.A. shimming seemed to help a little. Makes since about the vent, as sometimes seems fueling isn't quite right. Plus, the longer the drive (to Light Rail versus Tucson) gets worse. Will have to do a long road test. Will take the cap off tomorrow.
