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.

 

My buddies 6262 just let go last week after getting it tuned?

 

We had a 6765 crap out 2 weeks after install and tune. They replaced it under warranty

 

Is this just an issue with the journal bearing turbos? My ball bearing has been good for a year now.

 

Have the people on dsmtuners taken the turbos apart and looked at the thrust bearings ??

 

3 different precision turbos, all bought brand new, not one hiccup with any of them. SC60, SC61, and my current 6262, not one problem.

 

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

 

I did two months ago, thrust bearing broke in half. Turbo only had about 50 miles on
it.

 

Yes, with detailed pics...majority of them were thrust bearing failure. More than just failure lol. It looks like a bomb went off. The main guy over there who rebuild the turbos hasnt been able to find a reason behind it, like too much or not enough oil pressure, its happened on 15psi and cars up to 35psi. There is alot of speculation as to if the internals are Garrett parts or not. But i dont hear about the Garrett turbos like the PTE.

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.

 

Ours that failed was a billet 6765 JB. It seized, and chewed up the compressor blades like 1/16"

 

Damn, guess it is what it is, take my chances. Hopefuly i can get it warrantied if it goes **** up. Ive heard good things about the PTE warranty dept.

 

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

 

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...

 

Looks like PTE turbos becoming more like ebay turbos lol.

 

I have run around 8 6262 journal/bb and some 6265 and a 5857 w/ no issues yet (hopefully) power ranges from 3xx- 7xx

 

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.

 

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?

 

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.

 

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....

 

Well, that's the big debate. Instead of discussing it here for DSMs, read it for yourself and contribute it there

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

 

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.

 

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..

 

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.

 

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.

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.

 

That's correct. Precision and Garrett ended their relationship back in 2006, and have utilized new suppliers. I believe I know who they are, but don't want to spread any incorrect information on any internet forums. That's how problems occur. In the meantime, I have also been doing my own investigation on this issue, so once I come to some valid, verifiable information I will inform the correct parties with plausible solutions.
