hi i been given a 2ltr omega (x20xev) and im going to put the engine in my astra sport which has (x18xel) engine now before i put the engine in my car im going to remove the egr system and the A.I.R system and fit a 4-2-1 manifold but so that i dont have the eml light coming on can because iv disconnected the egr and that can i use my x18xel ecu? because i plan on leaving my wiring loom in my car as it looks the same as the omega loom. and once i finsh modding the engine itl be remapped anyway. and regards to the sump as its in a omega would i be able to swap my sump over on the x20xev? so that it will go in my astra

any info welcome
