BMW 323i E21 vs Lamborghini Aventador LP700-4 Drag & Track Misc by turboandstance - May 14, 2017May 14, 2017 Originally this E21 BMW came as a 323i out of the factory. But this guy had another idea, He swapped it with a S50B32 “E36 M3 3.2l motor” and built a badass engine. The S50B32 has been fully built and turbocharged with a Precision turbo PT7675! Here we got a video of this awesome E21 doing a run against a Lamborghini Aventador LP700-4! Watch the video below and leave a comment.
