Since the drag cars B204 was not rebuildable. We are building a B205 motor with the best parts out of some scrap motors I had around. Will loose a bit of compression, droppping from 9.2:1 down to 8.8:1 or so. This should not hurt us too bad. the longer rods and lighter pistons of the newer generation motor should help make up for the compression drop. Still going to run the little Gt3071.64 turbo for now.
