What is the difference between the S50B32 and other S50 engines?
The S50B32 makes 236 kW (321 HP) and 350 Nm. The other S50 engines are: S50B30 with 210 kW (286 HP) and 320 Nm (1992 to 1995).
Engines in one family share a basic block, but the turbo, the injection, the sensors and the engine computer can differ. A higher power version often has different pistons, a bigger turbo or a different fuel system.
This is why we ask for the exact code. Fitting a different version can work, but the wiring, the software and sometimes the gearbox must be changed to match.
Not sure? Send us your VIN and your gearbox code. We match the engine family, the year window and the parts on the engine before anything is reserved, and the check is free.
