Understanding Your 2016 Dodge Charger SXT Engine Options

So, you're thinking about an engine swap for your 2016 Dodge Charger SXT, huh? That's a bold move, guys! The 2016 Charger SXT, typically rocking the 3.6L Pentastar V6, is a solid car, but maybe you're craving more power, a different flavor of performance, or perhaps you're rebuilding a salvage and need a replacement. Whatever your motive, diving into an engine swap is a serious undertaking. It's not just about bolting in a new motor; it's about integrating it seamlessly with your car's existing systems – the transmission, electronics, cooling, exhaust, and even the suspension. We're talking about making a whole new heart beat within your Charger's chassis. This guide aims to shed some light on the possibilities, the challenges, and what you need to consider before you get your hands dirty. Think of this as your roadmap to potentially transforming your everyday sedan into something truly special, whether that's a tire-shredding monster or a unique custom build. We'll break down the most common and feasible engine swaps, discuss compatibility, and highlight the crucial steps involved in making it all work. Get ready to explore the exciting world of Chargers that go beyond their factory specs!

Popular Engine Swap Candidates for the 2016 Charger SXT

When you're looking at an engine swap for your 2016 Dodge Charger SXT, the Mopar world offers some seriously tempting options. The most obvious and arguably most popular choice is swapping in a HEMI V8. Given the Charger's lineage, this feels almost like destiny. You've got several flavors of HEMI to consider. The 5.7L HEMI is a direct descendant and a relatively straightforward upgrade, offering that classic V8 rumble and a significant bump in horsepower and torque over the stock Pentastar. If you're feeling more ambitious, the 6.4L (392) HEMI is another fantastic option, delivering even more power and a more aggressive driving experience. These engines are built for performance and will fundamentally change how your Charger feels and sounds. Beyond the HEMIs, some enthusiasts even explore supercharged variants like the Hellcat's 6.2L supercharged HEMI. Now, this is where things get really complex and expensive, involving significant supporting modifications to handle the immense power. But hey, dreams are free, right? Another avenue, though less common for the Charger platform specifically but still a possibility with enough fabrication, could be exploring other Chrysler or Dodge engines that share some underlying architecture, potentially simplifying some aspects of the swap. However, for a 2016 SXT, sticking within the HEMI family generally offers the best balance of performance gains and achievable integration. Each of these V8 options will require careful consideration of their physical size, weight distribution, and, crucially, their electronic integration with the car's computer systems. Don't underestimate the complexity here, guys; it's often the electrical gremlins that cause the most headaches!

Key Considerations for Your Charger Engine Swap Project

Before you even think about wrenching, let's talk about the critical factors that make or break an engine swap for your 2016 Dodge Charger SXT. First up: compatibility. This isn't just about whether the engine physically fits in the bay. You need to consider the transmission. Will your current transmission handle the increased power and torque of a V8? Often, you'll need to upgrade to a more robust transmission, like a heavy-duty automatic or even a manual conversion, which adds another layer of complexity and cost. Next, electronics. Modern cars are incredibly complex computer systems. Getting a new engine to talk to your Charger's existing ECU (Engine Control Unit) and other modules (like the transmission control module, ABS, and even the instrument cluster) is paramount. This often involves custom wiring harnesses, reprogramming the ECU, or even using standalone engine management systems. Don't skimp on this part; it's where many swaps go wrong. Then there's the drivetrain. If you're swapping from a V6 to a V8, you'll likely need different driveshafts, rear axles, and possibly even differential components to handle the extra grunt. Cooling is another biggie – a V8 generates more heat, so you'll need a larger radiator, potentially different fans, and upgraded coolant lines. Exhaust systems will also need custom fabrication to connect the new engine to the rest of your exhaust. And let's not forget fuel delivery. A V8 will require a higher-flow fuel pump and potentially different fuel lines. Finally, there's the budget. Engine swaps are rarely cheap. Factor in the cost of the engine itself, any necessary supporting components (transmission, differential, cooling, exhaust, fuel system, electronics), specialized tools, and potentially professional labor if you're not doing it all yourself. It's easy to double or even triple your initial estimate, so be prepared!

The Swap Process: Step-by-Step (Simplified)

Alright, let's paint a picture of what the actual engine swap for your 2016 Dodge Charger SXT might look like. Keep in mind, this is a highly simplified overview, and each step can be incredibly involved. Step 1: Planning and Parts Gathering. This is arguably the most crucial phase. You've decided on your target engine (let's say a 5.7L HEMI). Now you need to source the engine, a compatible transmission, the necessary wiring harnesses, ECU, motor mounts, exhaust manifolds, potentially a new radiator, and all the small bits and pieces that add up. You'll also need to research transmission crossmembers, driveshafts, and rear-end upgrades. Step 2: Engine Removal. Carefully disconnect all fluids, electrical connections, and vacuum lines from the stock Pentastar V6. Support the engine and transmission, unbolt the mounts, and carefully lift the entire assembly out of the engine bay using an engine hoist. Step 3: Engine Bay Preparation. While the engine is out, it's a good time to clean and potentially reinforce the engine bay. You might need to modify or fabricate new motor mounts to accommodate the V8. Check clearance for the exhaust and intake systems. Step 4: Engine Installation. Carefully lower the new V8 engine and transmission into the engine bay, aligning the motor mounts and transmission mounts. Bolt everything down securely. Step 5: Connecting Systems. This is the complex part. You'll connect the upgraded transmission, install the new driveshaft, and hook up the custom exhaust. Then comes the wiring – integrating the new ECU and harness with the car's existing systems. Connect fuel lines, coolant hoses, and the power steering system. Step 6: Fluid Fill and Initial Startup. Fill all necessary fluids: engine oil, coolant, transmission fluid, power steering fluid. Double-check all connections. This is the moment of truth. With fingers crossed, attempt the initial startup. Listen for any unusual noises and monitor all gauges. Step 7: Tuning and Testing. Once the engine is running smoothly, it's time for tuning. This usually involves reprogramming the ECU to optimize performance, fuel economy, and emissions for the new engine. Road testing is essential to identify any issues and ensure everything is working correctly under load. Step 8: Final Touches. Install any remaining components, tidy up wiring, and perform final inspections. The journey doesn't end here; it's an ongoing process of refinement and enjoyment!

The Electronic Maze: ECU and Wiring Harness Integration

Let's get real, guys, the most daunting aspect of any modern engine swap for your 2016 Dodge Charger SXT is the electronics. Forget the mechanical side for a second; it's the computer wizardry that often trips people up. Your stock Charger SXT has a sophisticated network of sensors and modules all talking to each other via a CAN bus system. When you drop in a HEMI, you're introducing a different set of electronic
