I just finished an install using a 13B-T manifold (from G&S of course) and a Garrett turbo. I'm very pleased with the results.

I don't have any pictures handy, but I'll try to describe it. I welded a piece of 3/4" cold-rolled steel to the 13B-T manifold. Then I drilled and tapped the steel and into the cast for the mounting bolts for the turbo.

As for the Garrett turbo, I think that a compressor A/R of.60 is too high for the 3B. On my turbo (which has a compressor a/r of .42) I don't really get any useable boost until about 2000-2100 rpm. After that...it's all good. If you had an a/r of .60 I think it wouldn't really spool up properly.

I'm running 9 lbs of boost and I haven't turned up my fuel yet. I can easily get my truck up to 130 kph (80 mph for the yanks) although I don't like to hold that for long. I'm passing, holding speed on hills and my EGT's are almost half of what they were. The max I can get it at is 900F under maximum load and really pushing it.. I've got lots of room to play with the fuel.

Anyway, that adaptor would have been very handy and saved me a lot of work. Get your Garrett turbo out of a Chrysler mini-van or a turbo LeBaron at the wrecker. Very cheap and easily replacable.
