[sleepless]

Regarding selling my Elise: It has lots of goodies on it, but it is also a stripped track car. So basically, the resale on it would suck. This is why I'm interested in upgrading it vs. say going for an Exige S (which is an option that I'm will to go with, but it will cost me over $30K easily). And, I'm not interested in a Z06.

Regarding my $15K choices: There are 3 supercharger kits out there to choose from and all are at or below $15K. There is 1 turbo kit which also would work, except I don't want a turbo. Then there is LittleRocket's NA proposal. And of course, there is the upgrade to an Exige S which blows my budget two-fold. But with the FF header and 2bular muffler off my Elise I should be close to 240HP (crank) and with a minor supercharger pulley swap, I'd guess it could run closer to 260HP with the stock ECU.

Now, I sit and scratch my head, and boy does my head hurt!
