Sorry to hear the Seadoo didnt work out ... I had high hopes ...
So what motor / impeller/compressor housing are you going with now ? 5mm shaft or 8mm shaft ?
Having read up on a lot of compressor graphs, a T70 or a T72 compressor wheel with upwards of 92mm outer diameter will give you good boost at 40k rpm.
Please take a look at maps on this page :

Notice the wheel specs on the maps. Most turbos selling on ebay had smaller wheels but i did find a few that have the larger wheels. A couple of examples are:

Also, you want to make sure the compressor A/R is as small as possible ... for low flow / low+early boost , these will work best.
These wheels have a shaft diameter or 7.9mm. Will that make it easier to couple a 5mm shaft motor in your opinion ?
