KOW-Tune specializes in upgrading Mercedes vehicles at their company in Przemysl, Poland. Last year we shared a Mercedes W124 they swapped with a M113 V8. This time KOW-Tune swapped a turbocharged 3.7 L M112 V6 into a Mercedes W201. The motor produces 434 hp (323 kW) and 616 Nm (454 lb-ft) of torque with a Holset HX40 turbocharger. Behind the motor is a 772.6 automatic transmission from a Mercedes S600 controlled by a Siemens EGS52 transmission control module (TCM).
