Rule 34 of the automotive universe: If it exists, there will be an LS-swap into it.
A very revealing message thread on MMSports.org chronicles the process of some insane wacko who has taken a BMW E36 M3 sedan and put a Chevy LS motor in it. It’s only slightly more cogent than the YouTube comments on a Miley Cyris video.
The car lived out most of its life as a bone-stock 1998 M3 example, with 161,000 miles on the odometer, and regular servicing. The 3.2 liter inline-6 that it shipped with was in decent health, without so much as a blown head gasket.
In fact, while the typical narrative for such a wacky LS-swap might be that the owner has a blown motor and only decides then to fit it with an LS, the perpetrator of this swap actually sought out and purchased his 1998 BMW M3 with the express intent of performing the swap.
After what we can only assume was a headache-inducing, perpetual tantrum lasting many moons and inflicting multiple skinned knuckles, the car runs and drives surprisingly well, with only an excessive leak from the power steering to see to. You can see for yourself in a running video of the LS-swapped BMW M3 on Vimeo.
