From what I remember of my S2000 getting more power from them NA is very hard and every expensive, talking thousands for 20-30BHP if your lucky.
Whereas the CTR, well the ones in those videos with those mods will all be 235-260BHP, it cost less to extract power from CTR.
Andrew Moore has a supercharged FN2 with 400BHP, he tried at first to keep up with the 911 yesterday on a roll so 2nd gear upwards and failed miserably, though that might be his fault, cough gear change. Then off the line he did not see where I'd gone and even I got a bit of wheel spin and had to ease out of it and back in again.
So yes you can super-charge the Civic too, but all your doing is spoiling it and in the first two gears you cant use any of that power. Do the same to the S2000 and you can make use of that additional power in both first and second still.
