hmmm... you're missing a big one in the i/h/e equation, as in the most expensive one in the group - the exhaust.
Any good quality exhaust that will help liberate measurable hp will cost you at least $800. So the bill is up to $2000 - twice your estimate. Another thing missing in your equation, that according to Hondata's own plots is required to make "decent HP gains" (as you put it), is the addition of camshafts. How much do you think a set of ITR cams will cost? $500 a set for used (K20.org)? $1100+ new? And that's all parts - no labor.
How much is your "220 hp" costing you now? And I say that in quotes as I know the true numbers from seeing the results with my own eyes - remember the friend I noted above... 197whp - from the front wheels, where there's a lot less driveline loss than a RWD car. The average for an AP1 bone stock is 197 RWHP.
Clear winner - S2000.
Myth busted - who's next.

Not true.
I've compared several dyno plots from Hondata, K20.org, King Motorsports, and this site - and the only advantage i-vtec seems to have over the F20/22's vtec is the K20 doesn't have the momentary blip that's seen in every F20/22 around vtec engagement. There's no midrange advantage - just no momentary drop, then spike in power where the F20/22's vtec kicks in. It's smoother - but where's the fun in that?

where is your dyno plot, show it.
It is not a Myth, and you have done nothing to "bust" it.......

Considering the topic starter can't find a mechanic on the Cayman islands that can work on a stock S2000 correctly, this is a tragically misguided idea.
NO. there is no "easy" swap to a K head or block being used in a S2000. Topic over.
The bench racing belongs in street encounters.
