Have fun.Thats alot of wiring to do.You might as well get a standalone managment system to help simplify it. https://www.nopistons.com/forums/pub...IR#>/blink.png

but is the engine mounts and plumbing and stuff of that the same, i mean i don't care about the wiring, how heckic could it be?

It bolts up but it has a electric oil metering pump instead.It'll bolt in tho.Why not just use the S4 front cover for the OMP and run S4 injection on the S5 block?That works and makes for a easy swap.

you need to change every harness in the car, all of the connectors are different
