There are two 550s from a 93 rx7 with a buy it now price of a whopping 60 bucks. Then send em off for cleaning.
I have a set of 550 and 850cc injectors if someone needs them.
I don't want to say you're wrong MeanGreen, but... you're wrong. The AFC can tune injectors down %50. For example, on my car, it runs 550cc injectors stock (like Joesephi said), and I could plug in 1100cc injectors with an AFC and tune them down %50 to run like 550cc injectors.
