lol, i hope its good now cause im running your old turbo and pipes on my 370 right now, about 100 miles and about 15 9psi passes, however i had to raise the turbo 1" cause i was having some oil drain problems under WOT so hope that was part of your problem

 

My cars never smoked or anything...

 

i love how everyone says they are junk maybe there set up was just junk if you cant help don't chime in

snyper i hope u can get some help or reasoning for this to happen it Precision should have the answer

 

Ill be pretty pissed if they blame it on me. I bought everything recommended by and from one of their vendors...

 

I'll be interested to see what they have to say about it. It is interesting it completely froze up like that without any contact.

 

Ya ill be pretty upset if mine freezes up, i ran a 1/8" (.125") restrictor for that 100 miles cause i had smoking problems with the -4 fitting but since i raised the turbo1" i put the -4 fitting back on.....i guess ill be calling dr.turbo for a rebuild and a 91 upgraded compressor if i have any problems, btw anyone know what he charges for the 91 uprade

 

The upgrade is 699. Unit will make about 100-150+rwhp more depending on your setup.

 

I will keep that in mind if I have any issues with my PT88

 

you got a brand new turbo if i remember correctly. they fixed the old one a bunch of times and it didnt work right so i got a new one from them. glad its running good.

ps, i had a good pcv setup with a ton of pull up top. i think that helps with the draining.

 

Well if they dont warranty it its going to you. Would the price be the same for my seized up turbo? Like I said..no contact on either side..just frozen.

 

I vented the rear of the drivers side valve cover
The ls6 valley cover
And the two barb fittings on the driver side as well as the oil cap open with a filter on top

Maybe i shoulda hooked it up the the inlet of the turbo to pull a vacuum on it under boost, but i figured venting it would be good enough...

Anyways, thats an awsome deal for the 91 setup, but hopefully precision repairs your turbo for free

 

More then likely the backplate collar and backplate itself have fused together. PTE should take care of it.

 

You talking about the exh side (iron) or intake (aluminum)? I don't know the name of the parts, just what they look like. I had to replace the shield looking thing that goes between the turbine/shaft and the center cartridge thing. The old one was falling apart and loosing little tiny pieces that hit a couple of the turbine blades on the way out.

 

The exhaust side is the dust/heat shield. I was talking about the aluminum/intake side. Yeah the heat shield will corrode with time......with an alky motor it real gets killed quick due to so much water.

 

DrTurbo..do you have any pics of the 91mm upgrade? I might send it to you anyways to have the upgrade done. Would my LS2 be capable of 1000whp with this mod done to the turbo?

 

Yes it would.....


The pics are in this link.....

Car went from 821 to 961rwhp....rear mounted.

 

I notice it has a 5" inlet but no surge housing, just empty space. Would it be possible to get it with a 4" inlet so I could fit my filter on it??

 

I think MIGHTYMOUSE inquired about that. He was told there wasn't enough material to machine the 5" inlet down to a 4" inlet IIRC.

 

Maybe the use of a different cover?

 

From my understanding there was no other cover when David converted over (or he would have used it). I'd PM him/Jose and confirm that and see if anything has changed since.
