Chrysler 2.0L Turbo GME Hurricane Engine (Specs, Reliability & Issues)

Updated: Dec 11, 2022

The 2.0L GME T4 Hurricane turbo is a direct-injection turbocharged gasoline inline four-cylinder engine producing 27- hp and 400 nm torque. This engine is part of the Global Medium Engine (GME) architectural family developed by the Fiat Chrysler Automobiles (FCA) group's powertrain subsidiary.


The American version, produced by FCA US, debuted with the Jeep Wrangler in 2018 and was followed a year later by the Jeep Cherokee.

Design

This engine has a low-pressure sand-cast aluminium cylinder block with cast-iron liners. In contrast to the closed deck engines seen in Alfa Romeo cars, the engine block features an open deck design. The lightweight 2.0L GME engine's crankshaft is offset from the cylinder bores.


The crankshaft offset reduces cylinder wall side loading by making the connecting rod more vertical during the power stroke.


The engine block also has a low-friction roller bearing balance shaft and a variable displacement two-stage oil pump. When the engine is under severe load, a two-stage oil pump runs in high-pressure mode, and in low-pressure mode during normal operation.


It also delivers oil to the piston cooling jets (piston oil squirters) in each cylinder bore, which control piston temperatures and reduce spark knock. The pistons are made of cast aluminium with four valve chambers and plasma-coated piston rings.


On top of the block is a cast aluminium alloy cylinder head. The 2.0 Hurricane head comes with four valves per cylinder, sodium-filled exhaust valves, a central injector, a MultiAir valvetrain with dual overhead camshafts (DOHC), high tumble intake ports, and a water-cooled, integrated exhaust manifold.


The intake and exhaust camshafts, which are both equipped with a dual Variable Valve Timing (VVT) system, are driven by a low-friction timing chain (an inverted tooth chain). The engine uses hollow shafts with polished cam journals to conserve weight (3.5 lbs) and boost lifespan.


The 2.0L GME T4 engine employs direct injection technology. The high-pressure fuel pump provides up to 2,900 psi for the high-pressure common-rail injection system.


This method uses multi-hole fuel nozzles to pump gasoline into the cylinders, providing for better fuel atomization and delivery accuracy than port injection.


The next step is a turbocharged intake, which enhances both performance and efficiency. There's a twin-scroll turbocharger with a low-inertia design and an electronically regulated wastegate. It is connected to the cylinder head since the exhaust manifold is incorporated into it.


The integrated and water-cooled exhaust manifold reduces exhaust temperatures, prolonging the turbocharger's life and accelerating engine warm-up time.


The intake is equipped with a water/air charge intake air cooler. The intake air cooler, throttle body, and turbocharger are all served by a separate cooling circuit. The cooling system additionally includes a variable flow water pump and an electric auxiliary water pump.


Water also cools the EGR (exhaust gas recirculation) system.


In select 2.0L GME turbo fours, a belt-starter-generator (BSG) is employed to assist the engine at lower rpm. This eTorque technology also improves auto stop/start performance and increases low-end throttle response before the turbo spools up.


The engine fulfils all current emission laws thanks to the GPEC4 engine-management system, which incorporates a close-coupled catalyst, wide-range O2 sensor, and C-EGR system.


Due to the combination of a high compression ratio (10:1) and turbocharging, the turbo hurricane requires a minimum unleaded regular 87 octane for excellent fuel efficiency and performance; 91 octane or above is recommended for maximum fuel economy and performance.


The 2.0 turbo Hurricane is a great alternative to the 2.4-liter Chrysler engine and the 3.6-liter Pentastar V6 engine.

Problems & Reliability

Because the engine is new to the market, it's impossible to say how dependable it will be over time. According to most owners, the engine light on a new car comes on after a few hundred/thousand miles.


This might be due to a number of factors. It might be a broken sensor, loose hoses, or loose connections, all of which point to poor manufacturing construction and subsequent quality control.


This is because the engine is new and intricate, with many components, and it takes time to test and deal with any issues that may develop.


Tuning

There are several aftermarket and performance choices for your Hurricane 2.0 engine, even though it is doubtful that this engine can provide impressive performance without a lot of work and a little bit of risk.


Performance Intakes

The performance intakes from aFe and Mishimoto are a good start to improving power and reducing restriction in the intake tract.


Higher power engines and remaps usually require or go well with a performance intake.


ECU Programming

aFe, Superchips, RaceChip, and DiabloSport have tuners that can improve the power of the engine.


Exhausts

Borla, aFe, Gibson, and Magnaflow provide exhaust systems. An upgraded exhaust system not only improves sound, but can also improve power by reducing restriction within the exhaust system.


This can be done by using an exhaust with a larger diameter, removing restrictive parts such as the catalytic converter, mufflers, or particulate filters, or reducing bends in the pipework.


Pick your performance components judiciously, yet these four cylinders still managed to post some outstanding results.


It outperformed disappointing larger-displacement six and eight-cylinder automobiles and showed better horsepower per litre.
