Thats a good question? and the only thing io have been able to get is that the newer turbos are blowing alot quicker than before. Hence to me that has to do with them using "thier own parts" now but then again i know some people with no issues at all so its a bit puzzling. I know that every company has its issues and stuff but still. Nobody has money to go jus buy a new turbo every year you know.

they aren't the same. PTE uses a different compressor blade set up. for example.


is the PTE billet compressor wheel


where

is the garrett billet wheel.

ooo 0_0 sexy picture haha yeah i can see the difference in the 2 wheels clearly. which do you think is a better design as they are not close by any means at least in the picture lol and i have the standard wheel i wish i had the billet but that not what came with my kit

i couldn't tell you honestly. i will tell you that the way the garrett is made is better for sure. you can see it in the blades themselves. those lines just help disrupt air flow by causing friction. garrett uses 11 blade technology which is old. and people say that precissions 12 blade technology makes more power but, i have yet to see this proven and only hear it from PTE fan boys. i can't imagine that 6 blades stacked on 6 blades will provide more consistant airflow than 11 evenly spaced blades. also the turbine wheels are different too. there are subtle differences but they are there. the pte blades are thicker twards the center where the garretts are the same size all the way through.

so thus there being no way to swap any parts as far as the entire chra goes at all then. So how would a rebuild go then with this sicce precision is not selling thier parts to anybody i mean there would have to be some way that they do since i hear people saying they are able to get rebuilt. Like i have stated before i have a guy locally that rebuilds turbos for $250 and they come out great but i jus do not have the money to do so right now and again i have no idea if this is exactly th issue or what yet im in the proccess of eliminating things as i do tests on the car

look under your CHRA to see if there is any oil build up under there. when my precission blew i had a oil leaking out of the CHRA.

johnnyb305mia

on the housing there is no oil the only place where there is oil is on that port for vaccum off of the turbo there is a bit of oil comming out of there and its due to the fact that i do not think i have it tght enough since there is some threads that can still be put it and you can still turn it but i hav not bothered to yet since i do not know what is going on. to me i still think the turbo may be bad but again zero shaft play at all and it doe not smoke very often at all but yet a bit of oil in ic pipes so im wondering if my return line has something to do with it but i do not think so since i have never had an issue until now

that could just be blow by. but it sounds like the turbo is on its way out. how old is the turbo? PTE has a 1 year warranty on their turbos and i got my 5857 replaced under warranty.

johnnyb305mia

it has about 13k on it and its been more than a year so no warrenty

When you called them what did they say to you? Do you still have the card that came with your turbo?

they told me that i could send it in and get it looked at and that any repairs would be out of warrenty. But that to check for shaft play both in and out and side to side cuz shaft play is very indicative of bad seals on the bearings but i checked the next am as i was doing the vc gasket since it was leaking and zero play at all n im not going to send it in when the local guys may be able to fix it if thats whats wrong u know

Have you had the chance to do a leak down test? It could be blow by from cracked rings too.

Sent from my ADR6425LVW using Tapatalk

johnnyb305mia

no i have not done one yet i am going to do one though soon but cracked piston rings would mean my car would be smoking all of the time wouldnt it? cracked rin landings sound more like it but would the plugs be covered in oil as well from either of those 2 things being an issue?

Not Id it's an small crack.

So after further tests my 6262 still smoked at times, even though the motor has perfect compression and a fresh head. Turns out the Precision's apparently hate high oil pressure, which from the head tap, our cars tend to be fairly high. I also have a 4an feed which isnt helping things. I threw in a .065 oil restrictor and no more smoke (Make sure to get the larger .065 restrictor not the smaller .035 which is for ball bearing turbos) Also make sure your return line is sufficient - Im actually using a 3/4" return which is probably a little overkill but oh well. If you think it could be a ringland issue, do a compression test, cracked ringlands will give you around 90-110 comp in one or more cylinders, you should be around 160-180 per cylinder.

Hmm so u think my turbo is jus getting too much oil in it and which is pushing it through the turbo to the hotside of the turbo? Also my plugs r fouled but good thing none of them were wet not look like they had any detonation I will b changing them asap now that the vc doesn't leak car runs smoother how much does that oil restrictor run me a few bucks? The thing is that it rarely smokes u know. Plus when I get on it sometimes just a bit it won't smoke and then after it won't smoke either n now that I cleaned the intake n breather filter car is not smoking like it did b4 either I dnt know if that's just coincedence though.

I pmd u gimmie a call if ud like I can discuss with you more what's going on I'm trying to keep this asa much as possible about the turbos n what my cars doing as possible u know

dawg if that was the case wouldnt a larger drain like yours solve that problem?

johnnyb305mia

I dnt think so I'm using the drian that comes with the decendant kit so that shouldn't be an issue an I'm also using the feed line from the descendant kit but he is not the first person that has said about these turbos not liking the high oil pressure but he was able to confirm it. Good thing about my kit is that I'm using descendant dp dump tube s pipe mvs wg 5557 turbo n their oil lines but that's it I have my own precision ic which is a 3" core my own aluminum ic piping with an hks bov not that mikey mouse bpv they use and everything is in working order 100% except for the turbo cuz I'm not sure so ima exclude that.

I'm jus afraid that ill starve the turbo of oil with the restrctor and if its not blown then blow of it but then again that could be the issue.What is the likelyhood of it just being that?

when i called PTE they i'm pretty sure they said 85psi is the max they can take and our cars are like what 30-65? i could be remembering incorrectly but what i do remember is that they asked oil pressure and when i gave them the numbers they say "thats not the issue then"
