Nothing greatly exciting about this model, but you can assume that being an auto that engine has probably never been thrashed as bad as a manual sedan for example. As always with hydraulic 20G's (yes this will be the same design as your sedan, direct hydraulic heads), the composite head gaskets tend to fail after 250,000km, just from pure age related degradation.
The auto's tend to be detuned from their manual siblings, so tend to be more reliable. By 1995, the WRX had been pumped up to 260ps, the STi RA a stagering 275ps (On the small green AFM and grey tops!! Relying on a 5th injector to atomise in the intake manifold to reduce intake air temps, kinda like water meth injection), but the lowly auto wagons still only put out 220ps, like the legacy RS 6 years prior to it, and are actually down on torque compared to the first release WRX manuals. These engines also DEF do come with a TD-04, nothing fancy. I can also tell you they are def open deck too. Sorry, don't know compression ratio, but my GUESS is 8.5:1, but there's a good chance they could be 9:1.
BUT don't let these comparatively "dull" numbers fool you, they are capable engines, and given a different ECU, they liven right up. Even the lowly auto rex engines still have far more potential than the legacy RS motors, and only take a gently tickle to produce very very decent power!
