Being a 4 cylinder 3.0 litre turbo diesel engine with 130kw and 380nm of torque from factory and the average fuel consumption of 12 liters per hundred in our conversions and with parts readily available both OEM and aftermarket, these engines make a great conversion.
We are also seeing huge power gains with just as much as a dyno tune.
