KA dilemma

I was pondering my 240's future this morning on my way to work. Here's what I thought.

What's more cost effective and yet still allows me plenty of power and daily driveability? A turbo KA or a RB25DET or RB25DETT? I've been thinking about the price to do all of these and from the looks of it a built up KA engine would cost me about 1500 for bottom end good for up to 15-18 psi and then there's the turbo kit say 4000. Where on the other hand I could just buy a whole RB front clip for about 4000 and then say 1000 max for the install from a reputable shop. So for a little less I end up with the potential for near unlimited power cababilites and a motor that will last me as long as I take care of it. On the down side it's not exactly cheap to maintain the RB25 motor, like replacing starters, alternators, water pumps, radiators etc.... I'm sure this would cost me alot in the long run. Whereas the KA motor is a US motor therefore many parts are readily available for repairs and cheaper. Also there the question of daily driveability. I want to be able to drive my car everywhere!! Not just on the track. Would the RB25 even be street legal in Cali? I'm guessing I would have spend a good chunk of money to "downgrade" it for smog purposes.

So any thoughts? I know, I know this discussion has been done to death, but humor me anyways.

Thanks guys.
