MSD injectors
MSD injectors
What is the difference between High and low impedence 72lbs injectors? It seems like everyone with 72lbs injectors are buying the low impedence injectors. Can I use high impedence 72lbs MSD injectors?

I didn't even know they made 72 lb. high impedance injectors.
Stock injectors are usually high impedance (KA and SR).
The reason the larger injectors are mostly low impedance is that they can stay open a shorter amount of time and can therefore control fuel flow easier...this obviously is important when dealing with large injectors for idling, fine tuning, etc.
Kind of broad questions...what exactly do you need to know? Go to http://www.electromotive-inc.com and download their instruction manual for the TEC III. It will explain pretty well all the differences.

Re: (cnichols)
can a sr20det use msd injectors and a jwt fuel rail without some kind of engine management etc?
