What ever it takes!!
Re: Precision 6466
You might want to do your homework before you buy any of the new PTE turbos. Ive read somewhere the quality of the bearings(china?) are not very good like there older gens but you cant believe everything you read on the net.

Re: Precision 6466
I have a PTE 6765. It was build right before the change was made to the 6766. It was great for around 2k miles. Now it has issues blowing oil. I have sent it back to PTE twice and still have the same issue.
I am going to try to rebuild it myself with a kit that is supposed to have better parts. If that fails. I will be buying a bullseye turbo.
I just hope for you if you buy one that it is of better quality than the one I have.
I don't see myself ever buying another PTE turbo.

I have a similar problem with my PTE6131, it turned out that I had too much oil pressure. My oil line pressure is 32.5-35 at idle. PTE recommends 9-30psi.

Re: Precision 6466
Depends on if you want to do a custom downpipe or use the stock one.

Re: Precision 6466
Im assuming its a BB turbo, and it doesnt have an oil restricter built into the bearing housing?

Re: Precision 6466
Have you cured the issue? I put a restricted fitting for a journal bearing turbo. But it looked a little to restrictive. So I drilled it out slightly. I made no difference.
Also when the truck is warmed up at idle. The oil pressure at under 30 psi. I still get smoke from the tailpipe. So I am thinking oil pressure may not be the issue with my truck. I even replaced the oil drain hose with a 10an along with larger fittings. No bends at all in the drain line.

Re: Precision 6466
The only off the shelf downpipes are for the stock style turbos, Buick PTE Turbos (which the downpipe has horrible access to the plugs) and the PTE SyTy exhaust housing. I think some have fitted the GT35R to the PTE SyTy exhaust housing as well. The bolt on solutions makes the popular.

Re: Precision 6466
Mine only smokes with extend idling, I have not fixed it yet. I think I have a solution this year, I am going to add a filter on the supply line to hopefully drop it a few psi. Have you measured the oil pressure at turbo? Or are you going by the engine oil pressure?

Re: Precision 6466
Thats my question. Can we use the PTE exhaust housing with a different turbo. Right now i have the old PTE44 that was rebuilt by PTE recently, runs great no smoke, but sounds like they use cheap parts to rebuild. May be looking for something when this one goes out.

Re: Precision 6466
Sir,
I have a PTE 64/66 Gen two on a Syclone and it runs great. But be aware that you will have to do a ton of work to keep the boost under control (ask me how I know). I am in the middle of putting the motor back together after a stuck boost controller. PM me your number and I can fill you in if you would like. However I run a Buick houshing so I can swap back anf forth between truck and car.
Thanks,
Bob

The turbine seal they use sucks then. Those are "easy" to replace. Don't get the straight cut one, get the notched one, much better.

Re: Precision 6466
I was going by engine oil pressure. Off a real gauge not the one in the instrument panel. And I have a oil filter on my oil feed so that should cut the pressure down like you stated.
I have been told it is the thrust bearing PTE uses. I will be replacing with brass bearings to see if this repairs the issue.

Re: Precision 6466
Well I can tell you from years of experience with a PTE Turbo. I have done everything from oil feed to return line just like recommended. And it is still a POS. I would not waste any more of my money on one.

Re: Precision 6466
You used a restrictor for a journal bearing on a bb turbo, and drilled it to a randomly chosen size? And it didn't work? Did you try the correct restrictor? It's quite possible that you did nothing but make it worse by using the wrong parts with the wrong size orifice. If that's the case, I'd try the correct restrictor. Also, check oil pressure at the turbo inlet instead of standard engine oil pressure. There could be a difference. I don't know. I've never checked.

Re: Precision 6466
I remember High volume oil pumps, are no good.
and also the oil issue, I had some how a extra qt in the system some how. It forced its self out the front cold side seal and I never caught it...untill later. Now my PTE needs a rebuild. Not sure about the cheap parts that are supplied..

Re: Precision 6466
I once owned a PTE 44. It was a good turbo. Never had any trouble. They may have the problems sorted out that have plagued many of their turbos. But they were unable to repair the current turbo I have. And I gave them several opportunities.
So I will be spending my money elsewhere when I am in need of my next turbo. I am just done with PTE.
