The big valve motor is a hoss! I'm sure a VW wasserboxer can be built, no problems there. BUT it won't solve the reliability problems inbuilt... corroding heads and flexy crank (no, a counterbalanced crank will NOT completely stop flexing in a 3-bearing shaft). So a BB 2.1 will still be prone (though perhaps much less so, especially if you use a forged Bug crank) to throwing rods as well as the dreaded leaky heads. If there was some way to modify the heads & blocks to stop the corrosion... eg build up the mating surfaces , machine them to match & use GASKETS... -- Andrew Grebneff 165 Evans St, Dunedin 9001, New Zealand <andrew.grebneff@stonebow.otago.ac.nz> Seashell, Macintosh, VW/Toyota van nut
