Just posting this because I searched here for a turbo rebuild write up and couldnt find anything in the past.I'll do a write up with pictures,diagrams,specs.My digital camera is broken so thats why Im not doing it yet.

Turbo-to Turbo manifold bolt: 40-47 ftlbs

Torque the compressor nut to 18-20 in-lb (that's INCH-pounds NOT foot-pounds)(1.5-1.6 ftlbs) Then continue to rotate the nut an ADDITIONAL 90 to 110 degrees. DO NOT use any sealers on the nut or shaft threads--the nut is self locking.

Tighten compressor housing to 145-165 in./lbs (12-14 ftlbs)

Turbine housing to 185-200 in./lbs.(15-17 ftlbs) Make sure turbine wheel does not contact the housing in any position.

Backplate 8 ft-lbs ( Correct me if Im wrong found two different torque specs on this.)

Oil drain flange 34ft-lbs

Oil inlet flange 38ft-lbs

Downpipe flange to turbo exhaust housing Torque to 32-40 ft-lbs

If anyone else has any torque specs on the backplate please post.

Except that torque ratings are dependant upon fasteners used, and there's all kinds of different fasteners used on turbos. Those specs might be right for 1 turbo, but there is no universal spec...

Hey its better than nothing. You know how many threads there are about this subject with no real technical answer? #1 most common response "make it snug"...

No information is better than bad information...

"make it snug" makes sense to a mechanic, and if you tell somebody that and they strip a bolt, it's their fault. You tell someone an incorrect torque spec and they strip a bolt, they're pointing fingers at you.

I have NEVER torqued the bolts holding a turbo together, 90% of the time you couldn't even if you wanted to.

Yep... good luck fitting a torque wrench in there.

well most small torque wrenches that do in/lbs should fit there! am talking about the ones that torque a MAX of 12-14ft/lbs
well myself i didnt torque any bolts around the turbo just tighten until they are snug, but i have this small torque wrench which i really find useful for torqing small bolts in tight area!

to get an idea what am talking about i got this one:

I know which wrench you are speaking of. I think what tony is trying to imply is when the turbo is clocked there are a few bolts that you can barely even tighten with an open-ended wrench less alone fitting a torque wrench in there.

What you could use is a crow-foot socket:
