Forget the SR20 swap, just turbo the stock engine and add some forged internals. That will give you a tough engine and good power and .4L more displacement, plus parts will be easier to find for the standard KA engine vs the SR.
Man, if I knew as much about cars when I was first car shopping, a 240sx would have been my first car. Though I feel the JDM engine swaps are getting overrated, I really like the front fender/bumper/fixed lamps swap. Make that a Sil-Eighty, with a 2.4L turbo'd engine! DO IT. DO IT. DO IT.
