Recently sold my BMW M3 track car and have some used S54 engine parts; 6 X CP pistons, 6 x forged con rods, 24 valves & competition springs, 2 x OEM camshafts, timing chains and guides. All for standard 87.5mm bore engine. All working perfectly before full engine rebuild. Kept as spares. Also 8 x new Harmonic Balancer bolts and 1 x new Cometic 0.030 head gasket. Located Brisbane. Postage at own expense, or could bring to Sydney or Melbourne in mid October.
