Your CAI will definitely not fit with a turbo. Sorry.

There isn't a problem running a flywheel with a turbo, just don't go too light unless it's a drag only car. On a supercharger, however, the stock flywheel is the best. The reason is that a lightened flywheel doesn't carry enough momentum to turn all the belt driven accessories. With a turbo, this isn't a problem. As for it spooling quicker, the flywheel has nothing to do with it- it's the size of the turbo's internals- cetrifugal mass, unsprung weight- it's a lot like wheel size in that it just takes more to get them running. The GReddy kit uses a TD05 turbo, which spools very quickly (Is it too late to talk you into a RevHard?).

I agree with boosted that you should definitely run some forged pistons. However, with the lower rod ratio of the B18B block, I'd also replace the rods, too- even with a moderate 8 psi. You could probably get away with the stock rods for a while, but wouldn't it suck to blow your low mileage engine while it's still low mileage?
