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 |

They do a LOT more then just give you an idle speed.  They also give you warmup control and easier starting from cold.  Its really part of what makes an FI car pleasant to drive. Implementing an IAC on ITBs is challenging. Its also been done, so you are not starting from scratch. I have it on my current 2258. I will say this though - PMB is working on a common plenum for stroker engines using a single TB (last I heard, it was going to use Miata TBs). There are good reasons why almost all modern cars have moved past ITBs. Zach |
