Counter to popular belief I do not stay up late inventing hairbrained questions for you all, although that is tempting sometime given the wealth of knowledge here. As of around 10:30 AM today this will be a real life scenario.
Let’s imagine I have a 2.0l case running 1.8 heads with a single Weber that runs but I want to convert back to FI. Let’s further image that I have both a 1.8 FI set up and a 2.0 FI set up sitting in the shelf. Which FI set up would I be best advised to use on this engine, and for bonus points and adding to the community knowledge here, why? BTW - planning on doing a tech day on this with/for the SoCal mafia once I get a plan together. Given what seems to be a trend back to FI (or at least renewed interest) I think it could be a useful tech day for the community. Thanks! |

The 1.7\1.8 runners are longer and don't line up with the 2.0 plenum. They don't have the same bolt pattern. The throttle body is smaller. You can ask the same question 3 times and word the q different, but it doesn't change the answer.

Hi Curt - take it easy please, and please also do try to remember that some of us are still new here and learning. I am trying to understand what and why, which seems like a reasonable thing to do. Now I, and others, know that the runners are physically different. |
