    Greetings,

    I've seen 1/2 VW engines, and 1/3 Corvair engines, but I can't seem to find any info on a 1/2 Subaru. I don't know that much about the Subaru engines, but I was just curious if it's been done, or if it's even possible.

    Thanks,
    Rusty

    Since it's liquid cooled, would be a major undertaking to plug all the leaks. Possible but not work the effort. Best to consider a smaller/lighter engine to begin with like the BMW.

    It's been "done" But it's far from easy. when I say it's been done, water cooled blocks have been both cut down, and stretched over the years. There's V-12 GM blocks, and v4 and v6's built off of chevy v8's too. .... It's certianly not easy.

    VW, and Corvair are "simpler" because there's no water jackets to think about. Also, they're older tech, and have more garage friendly tolerances. Half VW's are nearly a hacksaw job.

    There was a v-twin Merlin, too.

    I hadn't considered the water jacket problem, so that makes sense. That probably explains why I've never heard of one.
    Thanks,

    Yup, an Australian built it I believe. About 5 liters.
