Four cylinder engine question

Common down under [ ex Japan ]
this would be my engine of choice [ if I kept the hood shut ]
The S2000 engine is the only Honda that rotates clockwise, it will pull 9500 rpm with stock computer and make 200 hp with just an Air filter and exhaust mod
These things are almost a race engine in stock form, they are that efficient that you'll need to spend another $10K just for another 5 hp gain

These engines are very popular with guys track racing "Lotus 7" type clubman racers
