B58 F31 Swap — Full Project Compilation (Parts 1–4)

This is the full compilation of our complete B58 swap build on the BMW F31 — all four previous episodes combined into one full project movie. From tear down and preparation to turbo upgrades, M Performance parts, final assembly, and the first startup — everything in one video. We replaced and upgraded major components including the ECU, instrument cluster, turbo system, exhaust, bumpers, interior M Performance trim and carbon parts, wheels, and more. Step by step, the wagon was transformed into a true sleeper build. If you missed the series — this is the full build from start to first run in one place. Subscribe to follow the next stage — full drive test and performance results coming next.
