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.
My only reason for bringing in I/H/E is to show the potential of the engine. When the K20 breath well enough like the F20, they make similar power. But the engine of the F20 is much more highly tuned. So, all I'm saying is if the K20 gets that level of tuning, it can make more power. Not to mention much better low end tq due to i-VTEC. But whatever, for all we know, Honda can just drop the S2k all together.
