View Full Version : OT: FI on 3.8 Buick vs Chevy 4.3V6

I know that the Turbo V6 as well as the FWD luxury cars used a sequential multiport injection, and that the 4.3 V6 as originally found on the Monte Carlos and Grand Prix were throttle-body, thus comparing apples and oranges.

However, did the 4.3 eventually get a multiport, sequential injection later on? I think I heard of this, but it was after the RWD Monte and Grand Prix no longer existed (maybe used in the trucks?)

Anyone know details on this? Plus, if it does exist, can it be relatively easily adapted to the older TBI cars?

Yes, these are the strange things that occur to me at weird hours of the night.
