What is the difference between the S38B36 and other S38 engines?
The S38B36 makes 232 kW (315 HP) and 360 Nm. The other S38 engines are: S38B38 with 250 kW (340 HP) and 400 Nm (1991 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.
