    euro spec m20 B25 HP difference

    Does anyone know a close estimate on the HP number on a euro spec M20 compared to a US spec one? Cant find a very good answer. Also is there a market for the engine here in the states or is not worth someones time and effort?

    There is no difference.

    What sort of aftermarket are you looking for?

      Some Euro 2.5L cars had higher compression pistons. Not all though.

        The high compression engines were rated at 1 higher hp and a couple more pounds of torque but it was at a lower rpm I believe.

        They say 1 point of compression is a 3% increase in power so US m20 8.8:1 and Europe 9.7:1 is a hair under 3% additional power. Maybe noticeable but not much difference

        No one makes this car anymore. The government won't allow them, normal people won't buy them. So it's up to us: the freaks, the weirdos, the informed. To buy them, to appreciate them, and most importantly, to drive them.

          I'm more than satisfied with my cam'd and ported 731 head build, if that's what you're referring to. If you have the dogleg trans, i bet alot of people would be interested in that.

            Plus the b23 had aluminum motor mount arms, the 2 piece trans housing, lightened flywheel, better looking valve cover(imo). Yea you'd be able to sell it.
