4N Motorsport specializes in performance parts for B58, S55, N52, N54, and N55 engines. The company is also starting a new BMW project. It started when 4N Motorsport purchased a BMW 760li for $2,000. They will be swapping the sedan’s 6.0 L N73 V12 into a BMW Z4 (E86) hatchback. In factory spec these produce 445 hp (327 kW) and 442 lb-ft (600 Nm) of torque. However 4N Motorsport plans on raising the redline and fabricating a set of custom equal-length exhaust headers. 4N Motorsport plan to pair the V12 with a six-speed manual transmission. You can follow the project’s progress on @4n_motorsport or 4N Motorsport’s channel.
