Sanity check

I would look for a good used GN or Syclone/Typhoon turbo. They are sized small on those engines, so they are likely to be almost spot on, for our similiarly sized,
Depending on how your compartment lays out, take a tight J bend, from the exhaust manifold, over to turbo. This will allow you to locate, front or back, and side to side, for best clearance.
Make sure you are up to snuff on oil feed and drainback, which should be a fairly simple process.

Biggest obstacle will be fuel and timing control.

GO FOR IT!
