Currently have a 2.2E/S with Webers. It runs well and makes good power, having been tuned on the dyno and further dialed in since then, but I have discovered I'm just not a carburetor person. Fuel economy isn't good enough for the size of engine/car, and the emissions bother me—both in terms of the smells in my garage and while driving the car. And yes, we've been totally spoiled by low emissions cars.
What I'm curious about, for anyone who has lived with carbs and MFI: Is MFI noticeably cleaner and/or more efficient than carbs? Or is EFI the way to go? I'm in no hurry on this, but curious for the experiences of others. Yes, Motronic, but I actually like the 2.2 engine. Thanks! (IMG:style_emoticons/default/beerchug.gif) |

A problem with carbs and MFI is that a lot of unatomized fuel ends up in the crankcase over the miles. 3000 mile oil changes become a requirement.
Also, the cheapest decent throttle bodies are motorcycle... 1999 to 2000 GSX-R 750 or 1000 depending on the size you want. Triumph ITBs require a manifold. I did this on a 3.2 back in 2012 with megasquirt (which I'll never use again). |
