So my 2.4 is fresh -0 miles with only start up minutes on it. I rebuilt the carbs and powdercoated the steel air filter assembly and replated all the hardware and am really thinking of selling the setup in favor of running a 3.2 fuel injection setup on likely with an aftermarket ecu as I don't think the dme will work well with my setup..
Any thoughts or experience with what I am proposing? Now note that I have done this on a 3.0 before with good success just no experience with a higher compression low displacement solex cam engine.. Thoughts? |

I have used a 3.2 Intake on several engines with programmable ECU's. They all worked very well but I used pretty mild cams. Most aggressive was a 2.7 with E cams and it worked well (actually originally used CIS but had to set idle a 1300RPM to get it to idle). Since the overlap on solex is similar to E I think you will be good with 3.2 intake. When you get into cams with more overlap then reversion on a common plenum manifold can be a problem. Sequential injection can help as you can trigger injector after exhaust is closed at low RPM. Batch does not work well with large overlap and common plenum. ITB with big cams works well because throttle plates limit how far the A/F mixture can get pushed up the intake.
