Default Misc. WRX 2.0 Turbo engine/tran/mech. questions

Is the turbo in the 2.0 watercooled?

Has anyone used synthetic in the trans/diffs?

Easy to change your own oil?

Anyone come up with anything to prevent the little dimples that occur on the intercooler surface (I believe I saw this on projectwrx.com). I was thinking of some screen that could be put inside the hood scoop which wouldn't restrict airflow but would keep the larger debris out.

It looks like shifing to 6000 RPM in first gear is optimal based on the dyno curve I saw on projectwrx.com. IOW, 1-2 is a 45% RPM drop. The RPM drop lessens with the higher gears which is optimal from an accel. standpoint. Thus, it might be optimal for a 5500-5700 RPM shift in other gears (I haven't completely worked out the numbers).
