Now what could happen if you choose not to have new pistons you compress to much causing more force on the Piston rod then it can handle this will cause a blown rod. which is the piston literally shooting through your engine block. Now if you kept the stock ones it not 100% it will happen just a better chance. Ive seen far to many people try putting turbos and superchargers on cars without modifying the engine and ive seen almost all of them blow rods. In this case I would trust the professionals that made the supercharger.... if they offer pistons for it get it.

This site has some funny blown rod and piston pics...
Tuning the LET

with a change in pulley you can lower the poost a bit and you dont need to change pistons.

Oh ok I see now, 2k for the hardware to bolt the SC on, plus the cost of the SC its self, plus what ever power axle charges for their tuning. So probably ~$5500 not too bad. Without changing internals.

I'm really hoping PowerAxel gets this thing stateside soon. It looks like something I'd like to do with my Genesis. Although the internal upgrade would be required to make optimal power this kit should still provide some great results.
