the reason i asked if you'd considered an automatic was because it would make swapping a b16 along with the transmission that bolts right up to it, into the rear of your "off-road" vehicle much easier. there's no good reason to mount it up front then pay for a trans, driveshaft and rear end then engineer it all to work together, if you have the freedom to build the chassis to accept it as a mid engine configuration. you'll skip right over numerous hurdles and thousands of dollars in parts alone sticking with a proven combination of engine/trans. mount it in the rear, fab up some mounts and suspension pickups, and make some custom shift linkage. then put the other $10,000 that you would have paid trying to mount the engine in the front into good suspension components and you'll be much more pleased with the finished product.
