Failing PTE turbos?
Just curious if anyone is having issues with thrust washer failures on PTE turbos. Theres a whole thread on dsmtuners about this subject. Please dont turn this into a DSM bashing thread or anything like that. I just picked up a billet 6265 journal bearing turbo to run on my 1G and am starting to hear bad things. Any info is greatly appreciated.

Re: Failing PTE turbos?
I know a bunch of my friends have had PTE's fail, one friend lost 2 PTE Billet's in a year. (67 and a 72); now this weekend my friend just lost his 6265 that he's had for < 3 months

Re: Failing PTE turbos?
And also havent heard about it happening on the CEA (billet) turbos. they have all been the cast wheels turbos that seem to have the problem.

Re: Failing PTE turbos?
We've only used 2 different sized PTE turbos in the last few years.Both of them failed in a month or two of daily driving. Also both smoked hard on the dyno when throttle was let off. We never had a problem with Turbonetics, Garret, or even Godspeed turbos going out that fast , or even smoking at idle like the PTE's did. And PTE swears by NO RESTRICTOR on Hondas, so dont know what the deal is

Re: Failing PTE turbos?
Ran my car all last year with about 10k miles on it and have not had any issues with it.... I run a -3 feed on my car with no restrictor on it...

They also analyzed how they were setting up their oil feed system, be it oil filter housing or from the head. the main person I believe you were talking about is jusmx141. They are still addressing the issue to figure out what was going on with the Precision line.

Re: Failing PTE turbos?
How does the bearing explode? :O I thought at worst it would over heat and deform not really explode tho damn. Are they all billet turbos? Did it seem journal was more prone to breaking then the BB units?

Re: Failing PTE turbos?
Again. this is not a one size fits all problem. In some high pressure boost applications, like the ones mainly used on DSMs, there have been those that have fractured (exploded is an exaggerated term), due to high thrust loads, but yes, jusmx141 is focusing specifically on the JB series. Whether it was a billet or cast was not a factor, as they use the same bearing structure.

Re: Failing PTE turbos?
I know that depending on where you take the oil feed line from on a DSM the oil pressure will change dramatically.
If taken from the head, you will see something like 20-40 psi. If you take it from the oil filter location (like PTE recommends) you will see 80-100 psi. something to think about there....

For Hondas it looks like oil pressure and use issues that work.

Re: Failing PTE turbos?
Well my reason for this thread was to determine if it was a DSM thing or PTE thing. Seems like people using them on hondas are having some bad luck as well. Sorry for the exagerated "exploded" term. that was the term tossed around on DSMTUNERS. Ill be pulling my oil supply off the head and w/o balance shafts. with 50wt racing oil i measure 70psi cold idle and 50psi WOT.

Re: Failing PTE turbos?
only a few thousand on mine, but my 5857 on a honda application is working great. no smoking issues as of yet, but i'm also waiting for it based on other's experience. if it fails, i blame precision. they assured me the replacement they sent me after my last one died was "fixed" of the issue previous ones were having. my return is about as perfect as it can possibly be, correct lines for feed/return, so it's all on precision at this point..

Re: Failing PTE turbos?
I have had two fails with PTE sc61. The exhaust wheel came of on the dyno. PTE was very generus and fixed it. I sold the turbo to a friend with a b series after I got it from PTE and never ran it and the bearings was toast after a month or so and destroyed the compressor wheel when it had contact with the compressor houseing.. In both cases they made about 530hp at 25psi. The new billet series seems to work better with ball bearings though then the journal bearing ones.. I am to afraid of going with PTE again and to loose my turbo again. Both me and my friend are running garret turbos now on the exat same setups and have no problems.

Re: Failing PTE turbos?
From my understanding Precision lost Garrett support a few years back, so they may be using another supplier for their parts. This doesn't mean that their new supplier in any way is of inferior quality.

Re: Failing PTE turbos?
The bearing can have wear to the point where it looks like it "exploded". The ball bearing cartridge has a higher load capacity for thrust, and doesn't need a thrust bearing like JB turbos. I would like to look at other internals besides just the thrust bearing to get a better understanding of what's going on. It's hard to pinpoint a problem from looking at just one part.
