The power on a modded WRX (2.0L) or STi (2.5L)could be widely varied depending on what has been done to the car. My 2.0L WRX engine is modified with turboback exhaust, UTEC chip, bigger top mount intercooler and a cold air intake. I make around 250hp to the wheels with the stock turbo on 93 octane pump gas. The 2.5L should do that or better than that with a exhaust and intake.

From a pure power perspective I give the Suby the edge. Handling I would give the Boxster the edge. I have quite a few handling modifications but my 987S's handling is in a different league.
