BMW Z3 3.2i Engines for Sale | Engine Finders

BMW Z3 3.2i Replacement Engines

The Z3 3.2i was produced from 1998-2002 as part of the E36/7 chassis series, featuring the renowned M52TUB28 straight-six engine. Unlike the standard 2.8L Z3, the 3.2i variant shares its engine with the contemporary M3 (E36), delivering 321 horsepower. Common failure points include VANOS variable valve timing issues (OEM part 11361405127), cylinder head cracks between cylinders 5-6, and cooling system weaknesses. The dual VANOS system in the Z3 3.2i has specific calibration different from other M52TU applications, leading to unique failure patterns in this roadster configuration.

The Z3 3.2i uses a single engine code throughout its production run, with specific variations for different markets:

• S50B32: 3.2L inline-6 producing 321hp (European market only, 1998-2000)
• S52B32: 3.2L inline-6 producing 240hp (US market only, 1998-2002)
• Both engines feature double VANOS variable valve timing with unique calibration for the Z3 chassis
• Specific oil pump issues (OEM 11417532251) affect the S52B32 in North American Z3 3.2i models

The European S50B32 features individual throttle bodies and more aggressive camshafts, while the US S52B32 has a single throttle body and different emissions equipment. Both engines share the same block casting but have different cylinder head designs and management systems.

For Z3 3.2i owners, we recommend reconditioned engines due to the age-specific wear patterns and known VANOS system issues. Our engines undergo comprehensive inspection and rebuilding processes:

• Reconditioned engines with updated VANOS units (Beisan Systems repair kit)
• Used low-mileage engines from Japanese imports with under 60,000 miles
• Fully rebuilt engines with new timing components and gaskets
• Matching ECU and wiring harness available for complete swaps

Each engine is compression tested and comes with complete service history documentation. We specifically source engines from low-mileage Japanese imports which often have better condition internals due to different driving conditions.
