Is there a difference in a 2.0L out of a bus as opposed to a 2.0L out of a 914? I was under the assumption that a bus engine had different heads. I don't know where I heard that. Maybe I just made that up.

There are a number of differences between the two. Just a few I know of (Depends on the year of the bus vs 914):
Bus: 4 bolt intake heads with smaller valves No windage tray Different cam Used L-Jet for I think all versions 78-79 came in a carb'd version that had a mechanical fuel pump Bus engines are lower reving torque monsters compared to 914 2.0s There are tons more differences I'm sure. That's what's off the top of my little head. |

The cam was the same until 1977, AFIK, when they changed to hydraulic lifters. They'll rev the same as 2.0 914 engines, but the power is somewhat reduced by the head design, the hydraulic cam, and the L-jet EFI. The Cap'n |
