School me on injectors...
Not what I was expecting to see when I pulled them for cleaning...
I thought the '83 928s would have a Series 2 injector with O-rings on both sides and a short pintle cap.
What series is this injector and what was the progression through the early 80s L-jet and LH-jet cars?
Thanks all

All injectors from 80-84 US cars are that style. Euro are CIS.
Those are low impedance injectors, not cheap.
The two most common options are having them serviced by places like:
http://www.witchhunter.com/
http://cruzinperformance.com/
Or change over to a newer style injector using an adapter on the top end. This is an image from Greg Brown's website on the units he sells for this:

A more complicated route (which I did) is switch over to 85/86 fuel rails. None of the fittings line up so it's a complete custom option. I had one of the rails modified (moved a fitting) to make the hose routing easier.

Only if you're:
- not concerned about it being stock.
- handy and have acess to a lathe.
- like the idea of having an updated injector.
- etc.
Adjust impedence and lbs/hr to fit your needs.

You cannot go the other way around and install low impedance injectors in an LH car you could fry the brain.
