Yes, it's a shame the box got hobbled [box peak hp is 6000-6200 rpm vs. 996 3.4L 6800 rpm, 11.0 CR vs 11.3 CR, makes me wonder where the power loss is...DME, valve timing, intake/exhaust tract, or all the above? The 986S should be closer to 300hp!]. Porsche is a biz after all, and detuning the box makes sense, biz wise. Why cut off the arm that feeds you?

STi swap is debatable. If you're talking Value, in hp/dollars (you provide all labor):

300 hp stock/$9k (tranny adapter plate, electronics ECM, fabrication cost of motor mounts, plumbing, et...

+400hp-modded/ add $2k unexplored territory reliability wise, sky's the limit.

In that case, a supercharged boxter is ~300hp without all the packaging/fabing nightmares for $5k/$3k used. This would be much easier. Off boost response vs. turbo will be superior from a street standpoint. I vote stock modded if 300hp ish is the goal. 3.4L transplant doesn't seem like great value to me either, 325hp/$10k?

I hear Turbowerx is coming out with a 3.2TT kit. I would guess the price point would have to be somewhat less than a 3.4L swap for it to be viable. We'll see.
