i have Siemens Deka 80# injectors now but i am thinking i could use more injector...
so i am wanting to get some low impedance 120#ers or so...

i will buy new or used (rather used...lol)

also.. has anyone ever just added resisters inline to lower the voltage going into the injector therefor making it work properly with the low impedance injectors instead of buying a driver box?

 

Why not just buy 120lb high imp injectors so you don't have to buy a driver box?

 

I always hear about the versafueler

The low imp injectors take a lot of power to get them moving. The driver box is not just a bunch of resistors, it is an amplifier. That is why in addition to the eight inputs from your stock injector harness, a driver box has a power wire and a ground wire. It's kind of like an eight-channel stereo amplifier, driving eight 4-ohm subwoofers, with eight 8-ohm inputs from your radio. It probably wouldn't be too expensive to make a driver box, if you don't add in the price of the injectors that you ruin experimenting.

Im gonna try the hi impedance 120s when I upgrade

 

Try Nasty N8, a sponsor on LS1Tech. He does a lot of systems with low impedance injectors. http://www.nastyperformance.com/

To add to what Mike Gyver pointed out, the driver box also contians circuitry that spikes the amperage to snap the injectors open and then trails it off to keep from burning it out.

Do a search under the fueling and Injection section on LS1Tech and you will find quite a few people with postive reviews about the idle and low speed tuneability of low impedance injectors.

There is also several reviews about the new hi impedance, they look promising, and are plug and play for some people. If you can get around the price
