ok guy I jsut picked up my 720s from the rx7 store and i wetn to put them in and i reallized that I have a high imp. fual system. I test my 720's and they tested as 5 ohms, so now do I add a 10watt 10 ohm resistor to the injectors harness, if so were? Also do i have to change the injectos harness, the tops of mine are red (high imp) and they have the slots on them off centered, my injecotrs are a blueish color and they have the slots in the middle. No can i run the stock primaries, with out changing them to low imp, or do i need to cahnge those too. need help please help me. Oh yea I have a 10th ann.

damn same question as me, someone said my injectors where low imp. and so are the greddy 720ccs? I though the 720's where high imp. and you would need a resistor to lower the imp.. can someone please straighten us out? oh I just noticed you have an 89 J-spec block that would be a reason for you high imp. injectors....

no i have a 89 jspec turbo and manifold with a stock s4 block. mid 88 and up rx7s ahve high imp systems only 87s have low imp. i just dont know how to get the injecotrs in and how to makthem work right.

bosch style l-jet injector plug is needed for the GReddy's.. which i'm looking for right now since i just purchased 4 of them i'm about to just go to the salvage yard tomarrow and clip 4 plugs

yes GReddy's (Denso restamped) are low impedence. I guess polarity doesn' tmatter as long as the 10ohm/10watt is inline with the injector harness. so when you put the new injector connectors on just include the resistor.
