matthewswinimer Posted September 24, 2012 Share Posted September 24, 2012 hi there iam currently running stock 440cc highimpedance injectors and iam want to switch to 550cc injectors, i would like to just get a 550cc high impedance injector to replace it rather then go through the hastle of switching to low impedance. any suggestions?

David P Posted September 24, 2012 Share Posted September 24, 2012 Buy some 550cc high impedance injectors then. Quote Link to comment Share on other sites More sharing options...
Noz Posted September 24, 2012 Share Posted September 24, 2012 Isn't much of a jump, I wouldn't bother. I'd go 650cc. I went from 330cc to 440cc on my NA-T and due to other component limitations I could of got the same power on the stock 330's. The price and time of replacing them, might as well go bigger.

David P Posted September 24, 2012 Share Posted September 24, 2012 (edited) 650cc high imp saturation injectors are not good @ idle and low revs, that's why O.E. mostly go to low imp peak and hold for over 500cc. Larger size high imp are costly too, at the end of the day low imp is a proper job and costs less and it's only 7 wires to play with to fit a resistor pack. http://www.mkivsupra.net/vbb/showthread.php?233707-Project-Supracharger&p=3488364&viewfull=1#post3488364 Edited September 24, 2012 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
