408hp RB26-Powered BMW E30 M3

This E30 BMW M3 features a bold engine swap with a Nissan Skyline GT-R RB26DETT engine, modified with a single Borg Warner EFR 7063 T4 twin-scroll turbocharger. The build produces 408 hp at the wheels, indicating approximately 500 hp at the crank. The car is prepped for high-performance driving, including upgrades such as new spark plugs, coolant, and an AEM CAS trigger disc. It's a unique mix of German engineering and Japanese performance.
