  • EJ20E SOHC naturally aspirated

    I am the proud new owner of a 1997 Subaru Impreza 2.0 GL AWD.

    It is a standard British specification, I think. Therefore should be 113 bhp.

    I see from looking at that there is possibly another engine version with 133 bhp.

    What is the difference between these engines? Is there a way to extract the extra 20 bhp from mine easily?

    The non-turbo UK engines were all 115bhp, at least until the new age Impreza replaced the classic, when I think they had a mild lift to just over 120bhp.

    The higher outputs in the JDM model were likely down to higher octane fuel out there I'd guess? With a bit of basic normally aspirated tuning - breathing mods, a remapped ECU (if you can get them for the NA engine), you'd get some gains, but they won't be much in comparison with how much you outlay.

    If you really want more power, save the money you'd spend and put it towards a Turbo 2000.
