Precision PTE Turbo Issues - Blown, Smoking [Merged]

[TSI from Hell]

Justin, have you ever seen this guys post before? Not sure if I asked you this some other time.

Garrett Turbos...The end of a quality product - NASIOC

Interesting/Scary Post... Seems legit though.

I'll stay with MHI until I can get my hands on an Fp or Holset turbo.

Yeah it was steel, I still have it somewhere around here in a box of blown up parts. When the turbo got rebuilt a bronze one was used and so far it has been smooth sailing.

Wow, well that is very interesting.

That could be a big part of the explanation for what Justin has been finding in the thread here:
http://www.dsmtuners.com/forums/turbo-system-tech/344931-whats-deal-garrett-t3-thrust-plates.html

The thread name says Garrett, but actually most of the turbos he dissected were PTEs.
Jus didn't mention what kind of metal the failed thrust bearings were made from. I never would have expected steel.
Too bad. Now I know PTE was lyin when they told me they have their own in-house engineering department!

Spend the extra money and get a ball bearing. They are not very picky when it comes to oiling. I have run two ball bearing PTE turbos with no issues whatsoever and staying above 30psi boost pressure is normal with my car.

Yeah I think ball bearing is the way to go for aftermarket applications, where a given turbo model will be thrown at many different car configurations that weren't designed for it by the OEM.
Borg Warner seems to think so too, the new EFR borg warners are all ball bearing.

Ball bearing turbos have unsurpassed durability- that's no joke. You can run one without a blow off valve and surge the crap out of it, and it still boosts strong.

The only negative fact about ball bearing turbos are the initial price, and then the subsequent replacement / repair cost in the event of a problem. I've already seen cases where guys accidentally over-oil one and the turbine seal blew, and the only way to repair the problem is to replace the CHRA. TalonDave once owned a SBR GT13 (30R w/ 60-1 compressor). Great turbo, but he spun one rod bearing in the engine, and even with an Earl's inline filter somehow metal still made it through the turbo. The result was the turbo screeched and would not build boost out of the single digits even though it had absolutely no shaft play. The only solution was to replace the CHRA at a price tag which cost more than the used turbo's purchase price.

So i know there has been alot of talk about " Journal bearing " turbos and how to feed the oil ect but .With in the past year i have had 3 PTE turbos blow on me. The last one was a 6262 just this past weekend and less then 500 miles and only less then 2 months old .the compressor wheel is hitting the housing big time. Im starting to think pte isnt good anymore? Also still unsure of how the feedline should be set up even after trying different things . I have read and heard so many different things about how to feed the oil ect and yet no one seems to be 100% sure as to what you should run for a journal bearing turbo from what i can tell. The whole point of this post was to just let people know how i spent my weekend and how it turned out for me with my new blown turbo .

How have you been setting up the oil lines (both feed and return) ?

 

[1997_GSX]

-4 an from the OFH with no restrictor.

If high oil pressure
-3 an from the OFH with no restrictor.

At least a -10 return line with no 90 degree fittings and no kinks. Make sure your crankcase pressure is in check or a larger return will be needed.

These turbos like between 20 psi minimal load and no more than 80 psi at full spool.

Are you running any kind of oil cooler setup?

 

[secondnature]

I used to run a -4 from OFH with no restrictor. And blew 1 turbo . Then i was told to run a -3 from the head and dont look back . That was on the 6262. Every turbo has been a -10 return.

Are you running any kind of oil cooler setup?

No cooler at all

 

[brisvr4]

Interesting.
I have a 6262JB as well and mine seems to be just fine.
I have a -4 feed from the ofh with a -12 drain ( made up of -12 hose a 3/4 pipe at each end keeping a decent diameter inside the return )
I also have oil pressure that idles at just under 20psi and I never see more than 70 - 75psi ever.
Prior to the 6262 I ran a 5031JB for over 2 years with no problems with the same oiling arrangement.

Oil supply issues seem to be the biggest killer of these turbos. PTE is no real help with advice either!

Hey guys i just want to clear up a few things that ive been hearing and i hope you guys can help.

I have a precision 62/62 turbo and the blades are cracked and the housing is all scratched up......My guess is it had alot of shaft play and the blades hit the house?........As to my question would i be able to rebuild it or do i have to buy a whole new turbo. Thanks for the help

 

[JusMX141]

If you have that much wheel damage, it's junk.

...and another PTE turbo bites the dust.

 

[400hp93talon]

Duhduhduh duh duh....Another one bites the dust!!!!!........Ouch those aren't cheap either sorry bout your luck!

 

[sofakingslow]

Ugh I was hoping you guys wouldn't say that. I guess new turbo it is
