What abour R/S ratio? what about piston sideload?

so you want to rev a 2.3l Bottom end to 9000rpms?

The powerband of an NA motor is going to be high revving from a 4 cylinder, PERIOD. so you could try an be different, and use .1l of displacement more thinking its going to make GOBS MORE HORSEPOWER, when in reality, its not.

So insteand of building a shitty motor like the H23/F23, you could just buy an H22, an slap cams in it and make more power.

The amount of money it will cost you to build an F23/H22 hybrid negates the whole purpose. Maybe if you were building a purpose built race motor, that lasted 5-10 passes. But for the STREET, H22 with cams> any other H or F series motor, PERIOD.
