There is very little information on small turbochargers. I read somewhere that the RHF3 (I think the RHB31 is larger) powered a 650cc Daihatsu (diesel?) engine. 650cc @ 5000 rpm would generate the same airflow as a 250cc @ 13000. Of course, we'd still like to find something smaller, but under our budget constraints that's probably as small as it gets.

the RHB 31 is very small perfect for a 250 four stroke.

the electric supercharger is 3795 to 4500 dollars.

one other thing to keep in mind . Since the 250 ninja is a flat bearing engine you need to use a flat bearing turbo. If you have a ball bearing crank then you use a ball bearing turbo. I could be wrong but that is the impression I got. Still doing research at this point.
As for engine ware with nitrous . I have passed about 15 lb of nitrous 20 hp shot through my engine. Only problem so far is the clutch . I fixed that with beefer springs. I did have some engine damage but that was totally my fault . So far this year no problem .
