My car is a from the first serie 1982, (W460) short wheel base, with the 5 Cylinder 3 litre OM917 engine without a turbo and with a 4 speed manual gearbox. This setup is probably good enough off road, but not sufficient on road or used as a everyday vehicle.

Because of this, I replaced engine and gearbox with a 6 cylinder 3 litre turbo charged engine (OM603A) accompanied by a 6 speed manual gearbox. This is a setup I am very satisfied with.
