    Default injector upgrade 4 18rgeu

    got an 18rgeu inlet manifold with what looks like the factory injectors, I am going to be slapping a turbo on the side of this motor, wont be running any more than 14psi. Does any one know what injectors I can replace the old one's with eg 3sgte, 1ggte, 7mgte, something easy to get a hold of and not too much hassle to get them in???

    Any top feed injectors will work. 1G, 7M, 4A, maybe early 3S? If you need bigger you can use 13BT injectors (550cc) and if you need bigger again there is a range of aftermarket stuff available. I bought a set of 780cc injectors for my 18R-GEU.
