just my .02, i don't usually do this sort of thing, but i did this time. coming out to school on rt. 80 in PA I had an SS/SC come up on my ass on, flashed his highs; i moved over figuring aight he just wants to pass. I move over and he pulls up next to me and I hear him revvin it, he puts down the window and grins so i'm thinkin alright here we go haha. he downshifts and takes off about a second after the grin; i had to wait a second or so for my car to downshift and get out of 1800rpm in 4th (4L60E), he was a bit ahead of me i started catching up i didn't walk past him until about 130mph and then we chilled out and he got off the the next ramp. I was surprised at how quick it was it went from like 70 to 110 in no time. Never really went at it with one from a stop, but I was impressed even being that my car was filled in the hatch area, rear seats, and passenger seat w/ all my crap headin out to school, not sure how much the weight played a role, i think so, but not getting into a fight over it haha. pretty impressive cars, i've heard in factory form they can take out a (non-STi) WRX.
Beautiful car man, good luck with her!
BTW I went to check one out when they first came out at Gearhart Chevy and the sales guy was arguing with me that I was wrong and it had a 2.4L not a 2.0L
