This complete engine includes a 1mm over-sized 88mm CarBahn-CP forged pistons and ARP rod Bolts.
Connecting rod bolts are common failure items on S54 engines. In response, CarBahn Autoworks has developed improved rod bolts. We also increase compression from 11.5 to 12.0 to one and increase displacement to 3.3 liters with a larger bore. This rebuild includes a valve job with new timing chains, timing chain guides, timing chain tensioners, Vanos overhaul and all associated seals and gaskets.
