'87 turbos
I put a '87 stock turbo onto my hotair, it fits just fine, but you cannot just "reclock it" and stick it in.
First of all, you need the bottom turbine peice with the two bolts sticking out from a hotair turbo - to fit the stock bracket.
It's easy enough to clock it by just looking at the angles on a hotair turbo.
Secondly - There must be cutting!!
I can't remember measurements off hand but its a good idea to have a vice, or a big c-clamp with a bench, a hacksaw, measuring tape, etc.
You need to cut the compressor outlet, and the intake adapter so that the turbo, when seated on the bracket, will just barely have a gap between the cut intake adapter sitting in the intake.
Then you just use a peice of silicone hose and clamp them together. Works great - 17 PSI so far!
Heres an idea of how it looks after you cut/clamp:

Notice it doesn't stand out very much, so it looks decent.

Notice the throttle body gets turned about 25-30 degrees.. hmm Well there are adapters available but I beleive they come with a complete kit for a intercooler so that'd obviously be another project.

This shot you see the hose is obviously short, the two clamps around the hose - the turbo isn't going anywhere because its bolted onto the stock bracket.
