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.

S45 Specs

• 50/67mm Billet High flow compressor
• Quick Spooling 45/40mm High Flow exhaust turbine
• High strength internals with 360deg bearing
• Designed for higher pressure and high temperature turbine housing
• Water cooled bearing housing and quick spooling dual scrolling housing
• New electronic wastegate actuator (new turbo only, DV/BOV not included)

Requirements

• 3" full exhaust (to increase life of the turbo and the engine)
• ECU tuning (to increase preset power due to ECU load limits) - Please contact JM Turbo Cooper for local and regional tuners that require a custom tune for it to perform. JM Turbo Cooper
• One step colder spark plugs
• New oil supply line (to increase life of the turbo)

For engine and turbocharger reliability reasons JMTC requires a 3" or larger exhaust (from turbo to exhaust tip, no exceptions). As well as installing a new oil line and one step colder spark plugs. Tuning is not required but will be will help the turbo and engine reach their full potential. Price Includes the core charge of $250 that will be refunded when a rebuttable core is returned to JMTC. Refurbished turbos do not come with a wastegate actuator or one that has not been tested.

Discover the incredible JMTCs Super 42 high-pressure, high-flow dual-scrolling turbo upgrade by JM Turbo Cooper, designed for enthusiasts craving peak performance. With a substantial 42mm compressor, this turbocharger is engineered to deliver early and extended boost compared to the JWC turbo, resulting in outstanding response, torque, and power gains across the entire power band. The 42mm design also ensures an added kick at the top end when you need it most, making it the ultimate choice for those seeking an extreme street upgrade that delivers full race performance. It provides impressive torque, quick spooling, and extended durability. For race applications, consider pairing it with one of our aftermarket exhaust systems to unlock its full potential.

It's important to note that unlocking the extra power requires a custom tune. Running this turbo without a tune will result in minimal to no HP gain.

Estimated Performance Gains:

• Approximately 60hp with a custom tune, intercooler, downpipe, cold air intake, new plugs, basic maintenance, and carbon blasting/cleaning.
• 100hp+ (All of the above) in combination with a ported head, larger valves, ICE pipe, intercooler, and a 2.3/4"+ exhaust.

Please ensure you have a cleaned or new aftermarket catalytic converter and intercooler to avoid potential boost codes.

Key Features of the Upgraded Turbo:

• Brand new turbo with a 42mm compressor
• Lightened high-flow exhaust turbine
• High-strength K04 internals
• Upgraded 360-degree bearing
• Designed for higher pressure
• High-temperature alloy turbine housing
• Dual-scrolling turbine housing
• Water-cooled bearing housing
• Compatible with OEM Intake Boot (N14) and N18 Engines with some adjustments
• Fits AEM intake, NM Eng intake, and Forge Intake (Boot) Hose with minor adjustments.
