Those are some awfully strange looking injectors! What's the reason for the housing, does it eliminate the need for a fuel rail?
A few years ago, I collected all the parts I needed to fuel inject an Olds V8 engine, including a correctly rewired harness and stock 1227727 GM ECM. I did a great deal of research into the operation of the stock system but I never was able to get it to run because of hardware problems and fuel leaks.
I still have all of these parts and I'd like to try something with the Fiero to increase efficiency. This would use stock high-Z electrical solenoid injectors sealed with standard O-rings.
Do you think there's enough material in the stock intake to drill for bungs and weld them on? If not, maybe I should look into the SD intake, but I'd like to do this on a low-dollar budget since I know these projects usually descend into high-dollar money pits

As far as I'm concerned, TBI is only one tiny step ahead of a carburetor, so I'm very interested in figuring out a way to get one injector per cylinder.
