For sale. Set of 8, 72# @43.5 psi Siemens Injectors, low impedance. I ran them for about a year, +/- 1000 miles. Once I switched the the Vortech YSi blower, I started seeing 100%+ duty cycle, so Ive upgraded to 95#ers. You can run these with your LT1 or LSx ecm, by using a convertor box http://www.acceleronics.com/versafueler.htm These injectors have great street manners. $250 obo shipped. PM or reply here if interested.
