If they tune the K20 to the level of tune of the current S2k, I'm sure they can get 210-220WHP easily. That puts it around 250-260Hp already. 210-220WHP is not hard at all to obtain from the K20.
I'm not sure I understand the question, the S2000 has an F series engine, making it the RWD Honda with an F series engine.
So great you put out a 250 HP K series derivative engine for a RWD platform. The S2000's engine runs 240 HP already. You gained 10 HP at best. As a company, you just spent several hundred thousand dollars, if not millions a) redesigning the K-series engine to run in the correct direction and mount longitudinally in a car b) redesigning a transmission to mate to the K series engine (as well as the driveshafts, differentials, and axles) c) Testing this engine to make sure it doesn't blow up or break down d) Getting this engine to pass emissions in 50 states e) retooling production lines to make this new engine and transmission and whatever supporting hardware is involved
Also, your method of upping K series power is one that a car modifier would take. You have to remember that these cars are geared for the general (at least well off) public; not everyone wants to hear their exhaust note or ride in a car where the idle is obnoxiously loud. So then, realistically, I would say at best a K-series could put out is about 240 hp at the crank....just like the F-series engine you are trying to replace. It is not a financially viable option.
