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) |

My carbed 2.4 in S trim runs good, pulls smoothly from idle to 7000 rpm and drinks gas like crazy. Never really actually checked mpg but estimate low teens.
A throttle body is nothing more than that - a body that holds a throttle plate and facilitates linkage. The MFI ones provide an idle air adjustment circuit and I modded mine so that each has a vacuum port. Nothing more or less than what the PMO’s provide for more $. And you cant get more “compatible” or correct looking than using what the factory used for period fuel injection. Steve, bad ass street sleeper hot rod BTW! Righteous |
