Leave the SBC and flat6 conversions out of this.
Who has swapped a different engine into a 914? Something Japanese, great mpg? |

If you want really insane mileage and reasonable performance, look into freevalve technology. If you don't know what it is, it is simply a 4 stroke motor with no cams. The camshafts have been virtualized, and the valves are opened and closed with air pressure controlled by the ECU. You can have any cam profile you want, dynamically while driving. So at cruising speed, you have a cam profile that makes the best mileage, but the cam profile can change to improve acceleration.
This is a video of a guy that put it in a Miata. https://www.youtube.com/watch?v=E9KJ_f7REGw I think this would be really cool on a 911 engine. (IMG:style_emoticons/default/idea.gif) |
