Chrysler 2.0L Turbo GME Hurricane Engine (Design, Issues & Tuning)

Updated: Feb 2

✔ This article has been fact checked.

The 2.0L GME T4 Hurricane turbo engine is an inline four-cylinder gasoline turbocharged engine with direct injection. This engine is a member of the Global Medium Engine (GME) design family created by the powertrain division of the Fiat Chrysler Automobiles (FCA) company.

The FCA US-produced version made its debut in 2018 with the Jeep Wrangler, and the Jeep Cherokee followed a year later.

Chrysler 2.0L Turbo GME Hurricane Engine Design

The cylinder block of this engine is made of low-pressure sand casting and has cast-iron liners.

The engine block has an open deck configuration, as opposed to the closed deck engines seen in Alfa Romeo automobiles. The lightweight crankshaft of the 2.0L GME engine is offset from the cylinder bores.

The connecting rod becomes more vertical during the power stroke due to the crankshaft offset, which lowers cylinder wall side loading.

A low-friction roller bearing balancing shaft and a variable displacement two-stage oil pump are also installed in the engine block. A two-stage oil pump operates in high-pressure mode when the engine is under heavy load and in low-pressure mode during normal operation.

Additionally, it delivers oil to each cylinder bore's piston cooling jets (also known as piston oil squirters), which regulate piston temperatures and minimize spark knock. The pistons have four valve chambers, plasma-coated piston rings, and are composed of cast aluminium.

The engine has a cast aluminium alloy cylinder head. The 2.0 Hurricane head has a MultiAir valvetrain with dual overhead camshafts (DOHC), high tumble intake ports, sodium-filled exhaust valves, a central injector, four valves per cylinder, and a water-cooled exhaust manifold.

A low-friction timing chain (an inverted tooth chain) drives both the intake and exhaust camshafts, which are both fitted with a dual Variable Valve Timing (VVT) system. The engine features polished cam journals and hollow shafts to save weight (3.5 lbs) and lengthen longevity.

Direct injection is used in the 2.0L GME T4 engine. The high-pressure common-rail injection system can receive up to 2,900 psi of fuel pressure from the high-pressure fuel pump.

Fuel is injected into the cylinders using multi-hole fuel nozzles, which offers higher fuel atomization and delivery precision than port injection.

A turbocharged intake comes next, which improves both performance and economy. There is an electronically controlled wastegate and a low-inertia twin-scroll turbocharger. Due to the exhaust manifold's integration, it is attached to the cylinder head.

The water-cooled, integrated exhaust manifold lowers exhaust temperatures, extending the life of the turbocharger and speeding up engine warm-up.

A water/air charge intake air cooler is part of the intake system. A separate cooling system provides cooling for the turbocharger, throttle body, and intake air cooler. A variable flow water pump and an electric auxiliary water pump are also part of the cooling system.

The EGR (exhaust gas recirculation) system is also cooled by water.

A belt-starter-generator (BSG) is used in some of 2.0L GME turbo engines to help the engine run at lower rpms. Prior to the turbo spooling up, this eTorque technology further enhances low-end throttle responsiveness and auto stop/start performance.

The GPEC4 engine-management system, which includes a close-coupled catalyst, wide-range O2 sensor, and C-EGR system, ensures that the engine complies with all current emission regulations.

The turbo hurricane requires at least unleaded regular 87 octane for good fuel efficiency and performance; 91 octane or above is advised for best fuel economy and performance due to a high compression ratio (10:1) and turbocharging.

Problems & Reliability

It is hard to predict how reliable the engine will be in the long run because it is a new product on the market. The majority of owners claim that after a few hundred or thousand miles, a new car's engine light turns on.

Numerous causes could be to blame for this. It might be a faulty sensor, loose hoses or connections, all of which indicate poor manufacturing and quality control.

This is because the engine is brand-new, complex and it takes time to test it and resolve any potential problems.

Tuning & Performance Upgrades

Despite the fact that it is unlikely for the Hurricane 2.0 engine to deliver spectacular performance without a lot of work and a bit of risk, there are a number of aftermarket and performance options available.

Performance Intakes

An excellent place to start when trying to increase power and reduce restriction in the intake tract is with performance intakes, aFe and Mishimoto are a good option.

A performance intake is typically required or beneficial for remaps and higher power engines.

ECU Remapping

There are tuners available from aFe, Superchips, RaceChip, and DiabloSport that can increase the engine's power.


Exhaust systems are offered by Borla, aFe, Gibson, and Magnaflow. An improved exhaust system can increase power by decreasing restriction inside the exhaust in addition to improving sound.

This may be achieved by installing an exhaust with a larger diameter, eliminating obstructive parts like the catalytic converter, mufflers, or particle filters, or reducing pipe bends.

With careful selection of performance components, these four cylinders were nevertheless able to achieve some exceptional performances.
