Questions before undertaking Turbo rebuild...
I'll be installing a Turbo Rebuild Kit on my Primary Turbo this week-end. Are there any tips you guys can offer on taking Turbo(S) off the engine and taking Turbo apart so that the rebuild goes smooth. It's the first time I undertake such a task. All comments and advise is much appreciated. Thanks. -Jimmy

I think the most important thing is to mark everything to be sure that it goes back in properly. It's easy to get the housings and snails out of rotation. I learned this the hard way.
Also, mark the compressor wheel so that it will remain balanced when you put them back together.
Be careful with the carbon seals when installing. They are pretty easy to crack.
Gook Luck!

Just curious why you are doing one turbo. After going through all of the work to get them off and clean them up, it would probably be a good idea to just do both.

Don't forget to prime the turbos just before you put them back, (oiling them./put oil in lines,etc.). Also do a search, some here have already successfully and unsuccessfully completed this meticulous task.....
PS. Good luck.... You're gonna need it....

...Hopefully, photos of me kicking the **** out of the Turbo because of my inability to perform the rebuild, will not surface on the Forum. 
Wish me luck.

What I learned whem I rebuilded my turbos was that the stock Thrust Bearing (the big C shapped brass one) has 2 holes (bigger) and the Turbo City's has 3 smaller diametter holes, which is much more likely to clogg up compare to stock ones.
I took my turbo out twice after the rebuilt, and ened up using the stock ones for that reason.
The thrust bearing has no efect realy on the performance of the turbo exept for alowing oil through for lube purposes, and I think the stock one is just perfect, most importantly the Thrust Bearing can never go bad anyway b/c there is no physical contact with the shaft and cannot be worn out.
Also do both of them at the same time, is just a pita, nothing to worry, make sure you mark stuff up precisely and you'll be OK and make sure to clean and keep things extra clean.
Good luck.

Oh believe me!.,.. I'm gonna document the S#!t out of this rebuild (with video). So posting digital photos won't be a problem. Thanks.

Well..w here do I know those parts from???
Just a question, i also did a turbo rebuild with such a kit and it's fairly easy onces the turbo is open.
Just one thing... You'll need to have the turbo balanced before putting it back. due to the wear of the propellor shaft there may be some intolerance with the new bearings, still causing oil to leak and so on...
Be sure to do that. it'll cost you more than the rebuld kit, that's for sure

There should be no reason for those holes to plug just because they are smaller either.

I just think is a common sense that such little holes are way easyer to clogg up than the biger ones, don't you think?
It happen to me twice and I just don't wish to anyone have the same problem as I did, if is possible to avoid!
