USDM vs. JDM/Aussie Spec
Posted: Fri Sep 05, 2008 2:20 pm
OK, this may have been covered, I did a search but might have used the wrong search string.
Anyway, from a moderately reputable source (OK, it was Wikipedia... not so reputable) I see reference to the 'EJ22E'which is Aussie spec'd at 135hp, the US engine from '94 was 101hp from the factory. It's my understanding, from a good friend who's a Subie tech, that the early EJ22's were limited in their HP output by Engine Control. That seems to make sense, that they probably put a different ECU into the JDM vehicles vs the US market. I guess my question to the guru's whether or not this is the case and if so I don't see any reason why the US spec '94 EJ22 can't turn out 135hp in stock form. Am I correct in this?
