JP came out with their own line of FX engines but had Novarossi make them to their own specs. I know in the previous times, what JP does is get Novarossi engines and do their own "mods" on them and sign them off as modded JP engines.
The Crankcase is the same except for the "JP" on the side and the black coating.
The crankshaft is modded and coated.
Piston/sleeve is modded same as old RS an NS based JP's
And if you have the money: CERAMIC bearings
Found this in the JP FX Forum from daniz24 wich is super modded by JP himself:
