19-Year-Old Builds SINGLE TURBO N54 Monster — SEMA Ready

At just 19 years old, JJ Kuti and his father built a SEMA-ready 2008 BMW 335i — complete with a closed-deck, forged N54, a Frenchi Fab single turbo setup, and an 8HP70 swap — all in only two months.

In this Stance Auto Magazine spotlight, we explore the dedication, craftsmanship, and passion behind one of the most impressive young-builder projects on the BMW scene today. JJ Kuti didn’t just modify a 335i — he rebuilt it from the bottom up, forging the N54, upgrading the internals, and adding a powerful Frenchi Fab single turbo conversion designed for serious boost.

To handle the power, the car received a full 8HP70 transmission swap, giving it the reliability and shifting speed needed for high-horsepower N54 builds. The result is a clean, aggressive, SEMA-level 335i built in record time — a father-and-son achievement that shows what happens when vision meets determination.

Captured by the always-iconic eye of Donnie Rochin (@r0cean11), this feature goes deep into the details, engineering, and story behind the build.
