    Yeah. That extra half liter really slows the '06 down.

    If i am correct, it still holds a 7000 redline.

    I believe it was cut to 6500. Can anyone here with an 06 verify that?

    It redlines at 6500 now. Pictures on subaru.com are evidence enough.

    I'd definitely trade 500 RPM for the extra torque, though.

    P.S.

    It's just a trade off. Move the torque down low to make it driveable, but lose the pull up top. That also tells me that the 2.5 either isn't as balanced, or the valvetrain can't handle the upper revs. Odds are it's from the larger bore/stroke throwing it off balance in the upper revs.

    I went ahead and bought a white 06. I did think about the weight, and got it with the tuner ready package. The hood is hella light aluminum, and the fog light covers look really cool, but I’m not sure what else they did to it weight wise.

    All USDM WRXs and STis have an aluminum hood.

    I got my 06 a week ago, and before i got it i made sure it was what i wanted. I went ahead and test-drove the legacy, and the 05 WRX. The 06 felt a lot faster, and like i said before I got the T.R. package also, that package makes it cheaper and less heavy.

    I believe the TR is actually stripped down. Manual climate control and such. Designed to save money rather than increase speed.

    The pull up top hasn't changed, as far as I know. The previous 2.0L wasn't doing much beyond about 6,200RPM anyway. The new motor just gets you there much faster, but the upper range is just as good (if not better) than the outgoing 2.0L motor. I'm not sure about the new lower redline, but I imagine that reflashes will bump it up to 7,000RPM or beyond without consequence. A turboback and reflash on the '06 should make it easily match a Cobb Stage 2 pre-'06 WRX, if not beat it. The new motor is teh win.

    So you would probably buy an 05 rather than an 06 like everyone else in the world well i really like my 06, enough to not let it bug my too much.

    Oh hell no. I wish I had an '06. I love my '05, but I'd trade it for an '06 in a heartbeat if I could.
