1996 BMW M3 S54 Engine Conversion

BMW E36 M3 from 1996 with a professionally completed S54 engine conversion. This collector-owned vehicle has been used primarily as an occasional track car and for participating in youngtimer events.

The car has been properly maintained with no expense spared in its upkeep and engineering. It features a full S54 engine conversion using a sourced engine from a 2003 E46 M3. The original E36 M3 6-speed gearbox, clutch, and flywheel are retained. The exhaust has been modified to suit the S54 engine while maintaining an OEM-style setup with catalysts still fitted. The original E36 radiator and oil cooler are retained, and an E46 EWS system has been integrated to work seamlessly with the E36 ECU.

Engine refresh and upgrades include a cylinder head rebuild with new valve guides, stem seals, recut seats, and resurfaced valves. The VANOS unit has been cleaned, checked, and resealed. The engine block was inspected and honed for new piston rings, with all gaskets and seals replaced using OEM quality parts. New cylinder head bolts, main bearing bolts, and upgraded ARP rod bolts have been installed. Motorsport-coated main and rod bearings have been fitted, and the crankshaft was polished with bearing clearances checked during assembly. The oil pump was rebuilt with a VAC upgrade kit, and the water pump replaced with a genuine unit.

This E36 M3 offers a unique opportunity to own a well-engineered S54-swapped car, blending the classic E36 chassis dynamics with the performance of the legendary S54 engine. It is an ideal vehicle for serious enthusiasts, suitable for track use or making a standout presence at youngtimer events. The car has covered 165,312 km and is priced at 26,500 EUR.
