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) |

Just some thoughts. I've recently been tuning my 2056cc with D-Jet. I was running rich and with an AFR meter I discovered I was running about 10:1 AFR across the entire throttle range. I have since leaned it out.
I've seen people say D-Jet was used on up to 2.4L engines and with how rich I was able to get the mixture, I'd imagine you could actually get it to work with a 2270 engine. As others have said, it will take more to keep that larger engine cooler. |
