cosworth injector question
 
ive been looking for some injectors for my stage 3 build, ive been told to have a look at siemens black injectors there apparently better than dark greens. anyway the ones ive seen are confusing me a bit some say low resistance some say high resistance. whats the difference and whats the ones to go for? high or low? :?

im assuming your still using a standard spec ecu not after market! you will need low impedance injectors!

are you planning on going for more power in the future? if the answer is no, i would just stick with 803's :top:

i plan to have more power eventually but i was just wondering what the difference was in the high and low resistance injectors?

As stated already :top: if you are going for a stage 3 build and power just go for Bosch green 803's, when you are going for 400/500 horsies then look into super duper injectors, :top: :top:
