For one the flat plane crankshaft is bespoke in the P65 vs S65
So "Street version" in a sense that; external ancillaries (dry sump, smaller race alternator that doesn't have to drive the immense amp draw of stock electronics like the nav, radio, ac, etc) will be removed and replaced with it's "street" based counterpart
The P65 architecture itself (flat plane crank, bespoke rods, pistons, compression, bore, cylinder liners, etc etc, that make this a race engine) will remain.
