Hi,

I am looking at upgrading the injectors in my car as they are at Approx 98% duty cycle atm. I was reading that for my engine i can either put 540cc low impedance injectors in but will have to add resistors to the injectors, OR i can buy 850cc high impedance injectors and won't need to wire in resistors. I was looking to achieve 300rwkw with mods and currently am running 225rwkw at full duty cycle with the standard 380?cc injectors (also running power fc). I have heard that by running the high impedance injectors, idle quality is sacrificed and the injectors respond slower to throttle changes. I am looking for some guidance in which way to go. The car is driven on the road mainly so i want no real sacrifices in drivability and response. Should i run the higher capacity high impedance 850s or wire up the smaller 540s? Anyone able to tell me how difficult it is to wire in the resistors and how to do so?

Thanks guys

Jamie

BTW engine is 1jz-gte (non vvt-i) would have asked elsewhere seeing as this is a skyline forum but there a lot of knowledgable people on here :wavey:
