Posted by WindingRoad about 7 months, 2 weeks ago

This BMW S54 straight-six was rebuilt by Fletcher Made Horsepower in 2015 and is sold with a Tilton clutch, a Turner Motorsports custom-tuned Bosch SM4 engine management system, and a ZF 5-speed transmission built by Jim Blanton. The engine came from a 2001 BMW M Coupe acquired by the seller four years ago. A year later, the block received new pistons, rods, bearings, and a rebuilt cylinder head. Dynamometer testing in 2016 registered 417 horsepower and 313 lb-ft of torque at the crank. The rebuilt engine has since been driven 2,500 miles, a quarter of which was on the track. This powertrain package cost the seller over $18k to build is now being offered with $16k in additional parts and a bill of sale out of New Hampshire.
