2008 BMW 335i - N54 Single Turbo Build
2008 BMW 335i (Sport Package)

About This Build
The N54 is one of the best tuner engines BMW ever made. Started with basic bolt-ons and a JB4, made 400whp easily. Decided to go single turbo for better top-end power. The Precision 6266 spools surprisingly quick and pulls like a freight train to redline. Running meth injection for safety on pump gas. This thing embarrasses much more expensive cars at the track.
