I have one for the Japanese-market Impreza WRX STi Type RA.
Unfortunately I cannot locate the jpeg of the factory page on my HD
(though I seem to occasionally come across it when I don't want it, I
can't find it when I DO want it...), but have a printout, so:

"BOXER MASTER-4
BOXER-4 (then a symbol of an H on its side), MASTERPIECE, MASTER,
Matured Advanced Sporty/Economical/Reliable
EJ-20 2.0l FOUR CYLINDER 4cam16valva
TURBOCHARGER with INTERCOOLER
MAXIMUM POWER: 280ps/6500rpm
MAXIMUM TORQUE: 33.5kg/m/4000rpm
POWER WEIGHT RATIO: 4.250 (WRXtypeRA) 4.46(WRX)"

RPM  - TORQUE (kg/m)
1500-15
2000-18
3000-32
4000-33.5
5000-33.5
6000-32
7000-27
7500-24

RPM  - POWER (PS)
1500-28
2000-55
3000-120
4000-197
5000-230
6000-270
6500-280
7000-277
7500-267

PS is slightly more than hp, so 280ps =~290hp. Figures are SAE.

Usable torque is available from 2000rpm and gets really strong about
3000; it peaks at about 3000 and is a broad flat curve from there,
dropping only slightly by 6500 and still very good at 7000.
