You can find HX35 off the shelf.
GT2559v is okay if you drop your power level to ~250hp and don't rev the engine more than 4000rpm. Otherwise it's just way too small. The same thing with GT2259v, you'll get closer to 300 but still no high revs (which in my opinion is one of the best characteristics of OM605/6). CR engines are better when high revs are not needed, as they have higher efficiency.
