The Car

BMW E82 side profile

The heart of the build is a boosted N52. The short block was rebuilt for boost, a Vortech V3si feeds it around 10 psi, and 22RPD handled the tune on E85.

Everything downstream got the same treatment: N54 six-speed, clutch-type LSD, solid mounts throughout, Öhlins DFV revalved to spec, and 335i brakes with proper ducting. Chassis stripped, caged, and harnessed.
