NOT a good idea to take a small biek engine and 'charge it for a car.
The biggest bike engines already struggle a little to provide enough low end torque to make a car drivable - even something like a 7 !!
Turbos put on for POWER don't improve drivability.
Maybe if you put in a 16 speed sequential box or a CVT ??
( If you research the Honda screamers raced in teh 60s with 12-speed gearboxes and revving to 24,000 you'll see how small engine squeezing the last ounce of power can sound  )
