At some point, my motor (1974 2.0L) will need a rebuild. I'm not going to go the /6 conversion on this car. If I rebuild the motor to a 2056 or 2270 displacement, can I still use the FI system (D-jet)? Or is there some spot in here where it is better to switch to carbs? Or if I wanted to have FI then switching to L-Jet instead?
Happy to do some reading if you have it... (IMG:style_emoticons/default/chowtime.gif) |

Rebuilding the engine to a 2056 with a Web73 or a Raby cam, rebuilt heads, flat top pistons and 8.5to1 CR gets you to 115-120hp using the Djet FI.
That's a pretty fast 914 over a stock barely 95hp! A careful build with notched rods, everything balanced etc really helps and you still will get 25mpg if you keep you foot out of it. |
