Motor Conversion R52 (E39)

Description

Engine tuning by increasing displacement to 5.2 litres using a special billet crank-shaft, special con rods and an enlarged bore in combination with appropriate special pistons. Flow resistance of the intake and exhaust sections of the cylinder head is optimized. Four special sports camshafts are used to tune these sections according to displacement. Additionally, the engine management software (EMS) is optimized and newly tuned.
