The JMTCs S45 F56 turbocharger was designed with the street and track enthusiast in mind. We started with our huge 50mm compressor and upgraded quick spool high flow turbine to give you full boost quick and a huge amount of power at the top end. We also designed it to maintain the quick response of the original turbo but deliver much more torque and power.

This turbocharger not only delivers high torque in the low to mid-range but you will also see a power increase at higher RPM. No torque or power loss like you see with the original small 43mm turbo. If you are looking for a great street, track, or strip upgrade that delivers full race performance this is the turbo for you. Don’t be left at the starting line by any other car and get one our S45 turbos today.
