If that new 2.2-liter I-4 "K22" engine has the same horsepower as the K20Z3 but with a broader torque band, that engine could be a candidate for the Civic Si sedan coming late in 2006.

It would certainly be more desireable for American drivers, since you won't need to rev the engine so high to get decent performance like you have to do with K20Z3 on the Civic Si coupé. It might even make it possible for the installation of a beefed-up version of the Civic's five-speed automatic on the Si sedan, too.
