Hotside is done. On to the intercooler and charge pipes. Picked up a low mileage rear differential out of a 2008 BMW M5 with a 3.62 LSD and the factory M5 rear axles. The cases seem very similar outside of the car and we will be finding a way to get that to work in the back of the SAV as well beefing up any weak structural parts of the rear subframe so we don't have any tears. If the M5 diff is a direct bolt it would make the perfect gearing upgrade for any future DIY LSX X5 swappers.















Also in reference to the exhaust we thought about using ECS Tunings 3" Vacuum Exhaust Cut-Outs right before the 4.6is mufflers with custom piping to the cutouts and make it so that once the X5 gets into boost it opens the valve to cause no power restriction but around town out of boost it will have to go through the mufflers. We aren't dead set on this but we are considering it as an option at this point.
