That'a a good point - as well as being inhernetly stronger, the DI engines have a reduced compression ratio; I think the 3B is 21.0:1, the 14B is 18.0:1 and the 14B-T is 17.8:1.3b noob here. Been reading and learning for the past year, also forced into an informal engine overhaul. I do have a turbo, and I think the broken crank problem might be mitigated by retarding injection timing. These engines have a lot of compression and therefore cylinder pressure, so if you run a turbo, backing the injection timing off a bit can reduce the strain on the crank. I would never try to run more than 15psi either.
