With the turbos, if you increase cylinder pressures you'll likely cause other engine damage, from head gasket/head damage, pushrods, even rods. The diesels are more durable than a standard gasoline engine, but if they aren't designed for the turbo it won't last. The turbo will likely last longer than the engine.

Now if you use a "turbo" engine....well that's a different story....
