The NA option is not that hard either. I have about $750 in mine and it gets 270 Hp at 800 ft (almost enough) with 8.2:1 compression ratio and poor ignition above 6,000 rpm.
Peak power is at 7,500 rpm.
This s4 block, planetaries and rotors has no problem revving to 9,000 rpm

Reason: explain that revving is not necessary to make power from rotary
