    The Familia is what all Japanese "Proteges" are called over there. Got any pics??? It is also called the 323 still in other countries, such as Australia.

    And all-wheel drive is an option on almost all Familias...Sedan and wagon...

    Was it even called MP3??

    The Sport 20 is considered the ultimate Familia/Protege/323 there is. This year it is going to be both a sedan and wagon...So, I still hold to no Asia spec MP3...

    As for coming to the U.S., probably not. The next Protege (4th gen) isn't supposed to be out unitl 2003.

    Sorry John, but the gentleman are correct.

    The Mazdaspeed pistons will give a 10.7, and the J-spec is the latter, while the FS-DE for the Protege is 9.1.

    Later, Rishie

    I say, you shoulda bought a WRX if you're gonna go spending that much all together.

    The only way to break even is to sell your motor and ecu to a LX, DX or something and buy the FS-ZE with it's ecu and do it right.

    This way you only pay the difference, probably labor.

    Something I contemplated, but then I'd buy a WRX. I got this for looks and fuel economy. RWD is a true drive by the ass feel, hence the RX7's.

    Something interesting to note, I found a web-site that had a little conversion thing taking your current compression ratio and horsepower, and then you could type in a new compression ratio and it would tell you what horsepower you would make.

    Anyway, if it was accurate, going from 9.1:1 up to 10.5:1 only added about six (6) horsepower. Keep in mind, this was only changing the compression. Everything else would be the same.

    Since there is another topic on here questioning the worthiness of the cams, it leads me to believe that the exhaust manifold is the biggest bottle neck in the system. Which we already sort of knew, but seeing as the compression might only add about six, and the cams might only add another ten, that's only 156 or so...Where the hell is the other 14 horsepower at??
