factory horsepower for subaru engines
I was wondering what the factory lists the horses to be for it's various engines. The 2.5, 2.2, 1.8, the WRX, and the WRX STI. On the flip side, what can those figures be stretched to with modifications, excluding bore&stroke.
those are correct, though those are #'s to the crank HP, not to the wheels. You lose about 25% of the power unfornunetly
so
ej20t = 165-170 to the wheels
ej25t = 240 -250
dunno about the RS, but remember, these are averages, you can always get one with 178 HP stock to the wheels, lucky bastage :P

The new ej25 N/A engine I think is bumped up to 170 crank hp.
As for the older ej25 N/A (both SOHC and DOHC), they will dyno around 100whp, give or take 10hp depending on what kind of dyno you are on.

FWIW, my stock 04 WRX dynoed at 194 to the wheels, with 208 lb-ft of torque. This was not on a Dynopak either, this was a Dynojet AWD dyno, so we're not talking about a unit that typically reads high like the Dynopak.
