How difficult would it be to rip out the 450 engine and replace it with an E55 engine (not the supercharged version).
I'm after some more power and I guess the fact that an E55 engine would weigh less would help too. I suppose that you'd need to take the E55 transmission too ?
You would need the E55 transmission, fuel system, computer, exhaust system etc. Then you'd have to modify the front crossmember, motor mounts, cooling system, etc etc etc. Doable, but no easy task.
