Here's the start.

It's a Garrett T-76, .60 A/R compressor, 1.08 A/R exhaust. It was SUPPOSED to be for a future 3 rotor project, but I couldn't wait. So I'm going to try it on a 13B. I may have to go with a .81 exhaust housing, but either way I'll get it to spool. It's definitely good for more power than the motor will handle.
