here is a link to Holset to down load manuals for all there turbos. I found this and it is nice to have a brake down of everything, and tq specks I had to wing it on everything but the tq the 1st time I did it. Holsets are very easy to do. Just thought I would share this. Just pick the turbo you want. I down loaded 10 of them. Even for my HT-60 that I plan to make twins out of some day. I really prefer to do all my own work if I can. This also gives you shaft play limits if you are getting a used turbo. Hope this helps. If nothing else it's cool to look at.

Here is a link to High Tech Turbo, also a useful site when rebuilding your Holset.
