What motors are we talking about 2.3L , 2.3L DP, or 2.3T ? I believe the DP DIS injectors are the same #Lbs and high indpend injectors as the 2.3L single spark plug head 2.3L. I know the 2.3T (turbos) use a Low independence injector where the 2.3L N/A used a High indpend injectors simular to the 5.0Ls.
If your plaing to use a injector from a V-8 on a N/A 4Cyl make sure they are High inpend injectors and that there not to big for your EEC to deal with. Also you have to make sure the air is metered right.
**Example - A 93 ' 2.3L LX mustang uses a 14lbs high independ injector and you want to use a set of injector off a 94-95 GT which is 19lbs High indpend injectors you would need the MAF off the 94-95' GT also to swap on to your car. That is as big of a injector you can go on a N/A 4 cyl I think unless you really done some mods on your N/A and are pushing some power like 200+***
As for a using a turbo injector on a V-8 or a V-8 injector on a turbo 4 cyl it can't be done. It may can if you do a MAF convert on your turbo apt but not sure.
I knew I was something like that, thanks for the correction It wasn't until recent times I learned this stuff my self about the high's and low's of Impedance.
