I have always wanted to do ITB FI for my 2270. I found a box in my stash of parts with a DRLA 45 with one of the air bypass screws stripped. I found this thread on STFSTF IDF/DRLA to throttle body.. I guess I would have to block off everything above the throttle plate, and machine my manifolds to for injectors. Feedback on this idea is appreciated

Yeah, for simplicity the single can't be beat. Not only do you need the iac for warm up etc but in some cases it feathers the throttle when you snap it shut, keeping the engine from dying. If I were to move away from d-jet I would keep the injector locations and runners and just use a single TB + modern equipment. Although the itb would of course look so much cooler.
The first fuel injected (tbi/cfi) mustangs attempt at all of this without an iac is rather instructive. It has a 'kicker' that is used to catch and slow the close of the throttle, a kick that rescues it if it does dip too low, and another kick for when the AC is on, and finally a kick used to knock the throttle off of the cold start cam (all vacuum operated). The actual idle itself is controlled by the computer modifying the timing. |
