VAC Motorsports 82.7mm stroker crankshaft for BMW’s glorious S65 V8, as found in the E90/E92/E93 M3. Though this engine is relatively tuneable, there’s no replacement for displacement and so VAC’s UK-made (by Arrow Precision) crankshaft is one of the finest available. It allows for a longer stroke, meaning a sizeably bump in power and torque. Fits with all factory bearings, oil pump drive, flywheel etc.

4398cc capacity at 92mm (OE) bore size

4494cc capacity at 93mm (+1mm bore size)

4591cc capacity at 94mm (+2mm bore size)

Perfect in combination with Arrow Con-Rods and CP Carrillo Stroker Pistons.
