right now i have 6 550cc injectors on my T2, the 4 regular ones and 2 on the UIM (s4). I have bought a pair of 1600s and i want to swap UIMs back to one without the bungs on it, can i use as S5 UIM with the S4 LIM and TB, if that will work, can i use the mechanical oil metering pump arm or will i have to modify that?

i think you need a lower and an upper, but the tb's swap over fine and you can keep the mop

thanks, i think first i am going to tap out the injector bungs and try to seal them with a bolt and some sealant, if i'm leaking i'll spend the money for a new UIM or have them welded shut.



One last question, will the plugs from my S4/electromotive harness plug into the 1600s or do i need the plugs from an S5 harness?
