Stephan Papadakis Builds a 1200+ hp Turbo B58 Inline-Six

Davin Reckow from Hagerty’s Redline Rebuild visited Stephan Papadakis at Papadakis Racing to watch a B58 inline-six being built for Ryan Tuerck’s Formula Drift GR Corolla. The motor features a machined factory crankshaft, billet steel main caps, Supertech connecting rods, notched factory oil pan, and 3D-printed inconel exhaust manifold. On top Stephan installs a copper fire ring gasket under a machined head with aftermarket camshafts, steel intake valves, inconel sodium-filled exhaust valves, and billet aluminum intake manifold. The motor is good for 1200+ horsepower on E85 fuel. Watch the full build and some track testing in the video below.
