All...sorry, I posted this in the wrong place initially, so I'm reposting here....

I am working with Majestic Turbo in Waco TX to build a hybrid K26/K27 turbo. The K27 I acquired apparently came from a 78-84 era 930 (part number 5222-970-3100) and has the older style 3LDZ compressor wheel.

I am well aware that the 3LDZ is inferior to the later K27/2 wheels for a straight K27-style turbo. However, for my application (which is QUITE different than the 3.0-3.3L 930s on which they were originally installed), I believe it will be just about perfect. The benefits to the 3LDZ is that they are readily and inexpensively available (bringing down the total cost of my hybrid project), and mated to the smaller K26 turbine, I should be able to achieve the CFM I'm looking for, while retaining the quick-spooling characteristics of my K26 hot side.

Unfortunately, I have not been successful in finding a compressor map for the 3LDZ compressor wheel. Does anyone here have one, or have any tips on where to look?

Incidentally, if you're interested in more details on my (non-911) specific build, you an look here.

I have finally located a compressor map for the 3LDZ (!!!!) thanks to "copbait73" over on Pelican (here's the related thread over there...).

Here's the 3LDZ map:
