Injector Impedence Q

[DemonTSi at aol.com]

I've asked some of you guys this Q separately already, but I guess I should
introduce the Q to the group as a whole...
Basically, I was wondering if it's possible to run four injectors in
series-parallel from a single injector driver. You will have to use four
injectors of the same impedence as the original, and each of them should be
roughly 1/4 the size (cc) of the original also...but what else is there...?
The reason I ask is because I have an 87 Mitsu Conquest with the stock TBI
with a primary and secondary injector. I want to fab an intake manifold that
will allow each runner to have it's own injector (in this case, two). Then I
would run four injectors off of the primary and four off of the secondary.
This should ensure that the fuel is still delivered as it was originally
intended, only in a more uniform fashion. 
Any help with this would be great...!
Thanks
