Choosing the Right Engine for Your Swap

Alright, so you've decided to swap your engine. The next big decision is which engine to choose. This is where things get really fun! The most popular swap for the 2016 Charger SXT is the HEMI V8. This is a classic upgrade. It's a straightforward swap, offering a massive increase in power and a seriously cool sound. You'll need to consider a few different HEMI options. The 5.7L HEMI is a great starting point, providing a solid power boost. For even more thrills, you could consider the 6.4L HEMI, found in the Charger Scat Pack. Keep in mind that a bigger engine will often require a beefier transmission and other supporting modifications. Another popular option is the 3.6L Pentastar V6, which is the stock engine in the SXT. While not as powerful as a V8, this is an excellent choice for a simple, reliable upgrade, offering improved performance over a worn-out original. Then, there's the possibility of going with a turbocharged four-cylinder engine, for a combination of fuel efficiency and performance. These swaps can get complex, often requiring custom fabrication and advanced tuning, but the payoff can be huge. You can make an already agile car even lighter and more responsive. Consider the availability and cost of the engine. Do some research. The used market is a great place to start, but make sure the engine is in good condition. Be wary of engines with excessive mileage or a questionable history. Look at the compatibility with your car's existing systems. You'll need to think about the engine mounts, the transmission, the wiring harness, and the computer (ECU). You can't just drop any engine in; it needs to fit, and it needs to talk to the car. Your existing transmission may not be able to handle the increased power. If you are going for a V8 swap, you will also need to consider upgrading your transmission and rear axle. These choices should be based on your budget, goals, and mechanical experience. Always research carefully and consider all the implications before making a final decision. After you decide on the engine, you'll need to find a reputable source. Check with local salvage yards, online marketplaces, and specialized engine suppliers. Check for any warranties or guarantees offered on the engine. If possible, inspect the engine in person before you buy it. Look for signs of damage or wear and tear. Don't forget to factor in the cost of any supporting components. You might need a new exhaust system, a performance intake, or upgraded fuel injectors, depending on the engine. With all these things considered, you can choose the engine swap that best suits your needs and budget.

Gathering Parts and Tools

Okay, you've chosen your engine, awesome! Now comes the fun part: gathering all the parts and tools you'll need. This is where a detailed checklist becomes your best friend. Start by listing everything you'll need for the engine swap itself: the engine, of course, plus the transmission (if you're swapping it), engine mounts, and any necessary adapters. You'll also need fluids, such as engine oil, coolant, and transmission fluid. Don't forget about the little things. Things like new spark plugs, gaskets, and seals will be essential. Make a list of these small parts, and don't forget the fasteners. Bolts, nuts, and washers are easy to overlook, but they're critical. Then, there are the parts for any supporting modifications. If you're upgrading the exhaust, you'll need headers, a catalytic converter, and a new exhaust system. If you're upgrading the fuel system, you'll need a fuel pump, fuel injectors, and fuel lines. Double-check your list! You don't want to get halfway through the swap and realize you're missing a critical part. It’s always better to be overprepared than to have to stop the project because you’re missing a crucial component. Besides the parts, you'll need the right tools. This isn't a project you can do with just a basic toolbox. You'll need a good set of wrenches and sockets (metric, of course!), a torque wrench, a jack and jack stands, and an engine hoist. You'll also need some specialized tools, such as a harmonic balancer puller, a valve spring compressor, and a scan tool. A good quality scan tool will be invaluable for diagnosing any issues. If you plan to fabricate anything, you'll need a welder, a grinder, and other metalworking tools. Safety gear is also a must! You should wear safety glasses, gloves, and sturdy work boots. Consider wearing a long-sleeve shirt to protect your skin. Finally, plan where you're going to work. You'll need a clean, well-lit workspace with plenty of room to move around. If you're working in a garage, make sure you have good ventilation. You might also want to invest in a repair manual specific to your Charger model. A repair manual will have detailed instructions, diagrams, and torque specifications, helping you avoid mistakes. If you are not comfortable doing the work yourself, then consider hiring a professional mechanic. It's better to pay someone to do the job right than to risk damaging your car or injuring yourself.

The Engine Swap Process: Step-by-Step

Alright, it's time to get your hands dirty! The engine swap process is a big job, but if you take it one step at a time, you can do it. Always start by disconnecting the battery's negative terminal. Safety first, guys! Next, prepare the car for the engine removal. Drain the fluids: engine oil, coolant, and transmission fluid. Disconnect all the hoses, wires, and cables connected to the engine. Label everything! This will save you a huge headache when you're putting things back together. Remove the radiator, the air conditioning system, and any other components that are in the way. Once everything is disconnected, it's time to get the engine out. Attach the engine hoist to the engine, making sure it's securely fastened. Carefully lift the engine out of the engine bay. It will likely take some wiggling and maneuvering to get it out. Once the engine is out, the engine bay is empty. Clean the engine bay, removing any dirt, grime, and old parts. Now, it's time to install the new engine. If you're using the same transmission, bolt it to the new engine before installing the engine in the car. Carefully lower the new engine into the engine bay, using the engine hoist. Reconnect all the hoses, wires, and cables. Refer to your labels! Fill the engine with fluids: engine oil, coolant, and transmission fluid. Double-check all the connections to ensure everything is properly connected and tightened. Before starting the engine, check for leaks. If everything looks good, you're ready to start the engine. After starting the engine, allow it to run for a while, and monitor it for any signs of trouble. Check for any leaks and listen for any strange noises. You'll probably need to break in the engine, following the manufacturer's recommendations. This typically involves driving the car for a certain number of miles. Once the engine is broken in, you're ready to enjoy your new ride!

ECU and Wiring Considerations

Swapping the engine in your 2016 Dodge Charger SXT often requires modifications to the ECU (Engine Control Unit) and the wiring harness. The ECU is the car's computer, and it controls all the engine functions. When you swap engines, you'll likely need to reprogram or replace the ECU. The easiest solution is to use the ECU from the new engine. This ensures the ECU is specifically programmed for the new engine. Sometimes, you can reprogram your existing ECU. This requires specialized tools and software. If you're not comfortable with this, consult a professional tuner. Then, there's the wiring harness. The wiring harness connects all the engine components to the ECU. The wiring harness from your original engine may not be compatible with the new engine. You'll likely need to modify your existing wiring harness, or you might need to use the wiring harness from the new engine. This is a complex part of the swap, so take your time and follow the wiring diagrams carefully. Be sure to label all the wires and connectors to keep everything organized. When you’re dealing with electrical systems, it's crucial to be precise. A mistake here can cause serious problems. If the wiring seems daunting, consider hiring a professional to handle this. Finally, be prepared for some troubleshooting. Even with careful planning and execution, it's common to encounter issues during the ECU and wiring process.

Transmission Compatibility and Upgrades

When considering an engine swap, transmission compatibility is another critical aspect. Your existing transmission may not be able to handle the increased power of the new engine. If you're swapping to a more powerful engine, you may need to upgrade your transmission. There are several options to consider. First, research the compatibility of your existing transmission. Some transmissions are designed to handle a wide range of power levels. If your transmission is compatible, you may be able to use it without any modifications. This is the simplest and most cost-effective solution. If your transmission isn't compatible, you'll need to upgrade it. There are several ways to upgrade your transmission. One option is to install a stronger, more robust transmission. This will be able to handle the increased power of your new engine. Another option is to rebuild your existing transmission with stronger components. This can be a more affordable solution than buying a new transmission. The choice of which transmission to use depends on the power output of your new engine. If you plan to make a lot of power, you'll need a transmission that's designed to handle it. You may also need to upgrade other parts of the driveline. This could include the driveshaft, the rear axle, and the differential. Make sure all these components can handle the increased power. Proper research is crucial to determining the right transmission and driveline upgrades. Don’t rush this phase of the project.
