PTE questions/concerns

[John_GST]

Im planning on buying the PTE 50 trim (SCM 5031e) and I have a couple questions/concerns about running this turbo. I have heard that sometimes the bearing journals can't hold up to a certain high oil psi and that can cause serious shaft play. Is there any way to run a restrictor on the oil feed line to somewhat lower the oil psi or would that be a bad idea? If there is a restrictor, can't you just use a smaller sized oil feed line. Im running the RRE oil feed line which is the -4 stainless line. Would this line be pushing too much oil psi into the 50 trim? Thanks in advance.

I just baught a 5031RE, and in in the box was a piece of paper describing where and why to hook up to what oil line. this made no sense to me, since mine is a DBB CHRA. When I called them, I was told that piece of paper was for a standard bearing turbo.

So if a restrictor is needed, one will already be installed for you. And instructions on where to get oil from will be in the box. And of course, if you have any questions, just call them, and get they're advice. That way if something were to go wrong, It would have to be covered under warranty.

Not true....

Not true....

I didn't think that it was true, why are your reasons for stating that it is not true. Have you had any first hand experiance? Thanks.

Where did you find your 5031RE at?? I'm having trouble finding one in stock.

I got mine through TurboKits.com. I work right next to them, so I was able to keep in contact with PTE on the availability of the mitsu housings, since they talk to them everyday, numerous times. When i first wanted it, the hosuing were 2-3 weeks away.

Funny thing is, if you go to PTE's website, they dont even list the SCM series turbo's anymore. But I guess they are still making them upon request?

And I apologize for the whole "restrictor being installed" statement. Mine came with one, and I was told by PTE that they install them in every turbo that needs one before they are shipped. But thats just what they told me...

yes, i've owned three pte turbos.. none of them came with a restrictor built in.. (ball bearing one and two regular journal ones) I blew the seals out of one running a -4an line to the filter housing with no balanceshafts.. The next one i got i ran it with a -3an line to the filter housing, still no balanceshafts.. Didnt smoke at all. I will always run a -3an line with the pte turbos now if i go to the filter housing

ya and your's was very, very informative..

 

[John_GST]

Thanks Everyone who posted information. And thank you burnett03 for clearing up the issue for me. Now I just have one last question. Where did you get your -3an line at?
Thanks again I have been wondering if the -3an would work I just wanted to know for sure.

 

[TurboBlue]

Just to clear up my previous statements...A restrictor being already installed is a new thing that PTE is doing. Since they just started this recently, it explains all the other situations of no restricotr and seals blowing. My mistake

 

[John_GST]

Does anybody know where to get a -3an line for the oil feed?

 

[Shane2GSX]

So basically if you use the -4an your turbo gets too much oil and can be damaged, but if you use the -3an, it's safe?

I ran a -4an with no restrictor on my pte scm5031e, and had no issues. If the oil return line is good then it shouldnt be a problem.

Agreed.

I ran several PTE SCM and SC turbos with no problems from my RRE stainless -4AN oil feed from the oil filter housing. If you have a good oil return line (-10AN stainless or pushlock), you will have no problems on the thrust bearing models.

If it is a ball bearing model, people usually take an oil feed off of the cylinder head with an inline oil filter to the turbo without a restrictor. If the oil feed is taken off of the oil filter housing, then a -4AN line to an oil restrictor then the turbo is the reccomended way.

 

[Shane2GSX]

Okay. Well, I'm getting a -10AN return that is rubber, should I go with stainless instead?

 

[Burnett03]

i can get you set up with a -3an setup, just email me [email protected]

no, that is just fine, as long as it is not cheap rubber hose. I would prefer if you used a textile reinforced high-temperature hose that is oil resistant.

For example, take a look at the post below from a thread long ago regarding oil return lines. I have two pictures attached with good quality oil return line kits from Extreme PSI.
