What You'll Need: The 2JZ Swap Essentials

Alright, ready to get started? First things first: the parts. The 2JZ Nissan 350Z engine swap kit typically includes all the essentials, but it's essential to know what goes into the kit. Let's break down the major components you'll need for this conversion. Obviously, you'll need a 2JZ engine. Source it from a reputable seller, and try to get a complete engine with all the ancillaries. The engine should come with the wiring harness, ECU (engine control unit), and all the other bits and pieces that make the engine run. The 2JZ-GTE is the most popular choice, but the naturally aspirated 2JZ-GE is also an option if you are planning to boost the engine later on. A transmission is also something that you should consider. You'll need an adapter plate to mate the 2JZ engine to the 350Z's transmission or consider upgrading to a more robust transmission. Popular choices include the Getrag V160/V161 from the Supra or a similar strong manual transmission. Make sure the transmission can handle the power you plan to make. Then, a custom engine mount kit is essential. This kit allows the 2JZ engine to bolt into the 350Z's engine bay. The kit usually includes engine mounts and sometimes transmission mounts, and are specifically designed to align the engine correctly and provide adequate clearance. Upgraded fuel system is another important piece. You'll likely need larger fuel injectors, a high-flow fuel pump, and possibly an aftermarket fuel pressure regulator to supply the engine with enough fuel, especially if you're planning on running more boost. The cooling system is also a must-have. You'll need a custom radiator and intercooler to keep the 2JZ cool. The radiator might need to be custom-made or sourced from a company that specializes in 2JZ swaps. The intercooler is essential for turbocharged setups, as it cools the compressed air from the turbocharger. The wiring and engine management system is something that cannot be overlooked. The 2JZ engine will need to be wired into the 350Z's electrical system. This can be complex, and you might consider a standalone engine management system to simplify the process and allow for precise tuning. Don't forget about the exhaust system. You'll need a custom exhaust system to fit the 2JZ engine. This includes headers, downpipes, and a cat-back exhaust. The exhaust system not only affects performance but also the sound of your car. The driveshaft might need to be modified or replaced to connect the transmission to the 350Z's rear end. Ensure that the driveshaft can handle the power and torque of the 2JZ engine. Also, consider the gauges. You might want to upgrade the gauges in the 350Z to monitor the engine's vitals. This includes a tachometer, oil pressure gauge, water temperature gauge, and possibly a boost gauge if you have a turbocharged setup. If the 350Z has other features, such as air conditioning or power steering, you'll need to make sure these systems are compatible with the 2JZ engine. This might involve custom hoses, brackets, and pulleys. Finally, always have the right tools. You'll need a good set of tools, including sockets, wrenches, screwdrivers, and specialty tools for engine work. Having the right tools makes the job much easier and safer. Don't forget, safety first! Wear safety glasses, gloves, and use a jack and jack stands to support the car. Having a well-equipped workshop with enough space to work is also essential. Before diving into the project, it is recommended to get all the parts beforehand.

Step-by-Step: Installing Your 2JZ

Alright, let's get into the meat of it: the actual swap. Remember, this is a general overview, and every build is unique. Always consult detailed guides and seek professional help if you're not confident. First, preparation is key!

The engine mounts are usually included in the swap kit. The engine mounts are usually bolted to the 350Z's chassis and the 2JZ engine. Lower the 2JZ engine into the engine bay. Once the engine mounts are installed, carefully lower the 2JZ engine into the engine bay. Use an engine hoist to position the engine correctly. This may take some adjustments to get the engine aligned properly. Now, connect the transmission. Bolt the transmission to the 2JZ engine, using an adapter plate if necessary. Ensure the transmission is securely mounted. Install the wiring harness. This is where things get tricky. You'll need to integrate the 2JZ's wiring harness with the 350Z's electrical system. This often involves splicing wires and making sure all the sensors and actuators are connected. Get the fuel system in order. Install the upgraded fuel injectors, fuel pump, and fuel pressure regulator. Make sure all the fuel lines are properly connected and that there are no leaks. Install the cooling system components. Mount the custom radiator and intercooler. Connect all the hoses and ensure that everything is properly sealed. Install the exhaust system. Install the custom headers, downpipes, and exhaust system. Ensure that the exhaust system is securely mounted and that there are no leaks. Then, install the driveshaft. Modify or replace the driveshaft to connect the transmission to the 350Z's rear end. Ensure that the driveshaft is properly balanced and aligned. If you want to, you can install the gauges. Install the gauges to monitor the engine's vitals. Mount the gauges in a convenient location and connect the necessary sensors. Fill all fluids. Fill the engine with oil, coolant, and any other fluids required. Always use the correct fluids for your engine and transmission. The final step is to start the engine. Once everything is connected, double-check all connections and start the engine. If the engine doesn't start, retrace your steps and troubleshoot the issue. Then, tune the engine. Use a standalone engine management system to fine-tune the engine's performance.
