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

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

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

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.

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?

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??
