Finding a solid 350z 2jz conversion kit is the first step toward building one of the most reliable drift or street cars out there. Let's be honest, the Nissan 350Z is a fantastic chassis. It looks great, it handles well, and it's relatively affordable. But that VQ35 engine? It's a bit of a polarizing topic. Some people love the "trumpet" exhaust note, but many others get tired of the oil consumption issues or the high cost of making big power on a stock block. That's where the legendary Toyota 2JZ engine comes in. It's the swap that just makes sense, even if it feels like "heresy" to some purists.
The reality is that a 350z 2jz conversion kit takes a lot of the guesswork out of what used to be a complete fabrication nightmare. Back in the day, if you wanted to put a Toyota straight-six into a Nissan, you were looking at weeks of custom welding, hacking up your firewall, and praying your driveshaft alignment wasn't off by a few degrees. Now, you can basically order a box of parts that lines everything up for you.
Why Put a 2JZ in a 350Z Anyway?
You might be wondering if it's worth the hassle. The 2JZ-GTE (or even the GE if you're going NA-T) is famous for a reason. It's an overbuilt iron-block beast that can handle 600 to 700 horsepower on stock internals without breaking a sweat. The 350Z chassis, specifically the Z33, is incredibly stiff and has a great suspension setup. When you combine Toyota's bulletproof power with Nissan's sharp handling, you get a car that can dominate at the track and still drive home.
Using a 350z 2jz conversion kit ensures that the engine sits where it's supposed to. Weight distribution is always a concern with swaps, and while the 2JZ is a bit heavier and longer than the VQ, a good mount kit keeps it as far back toward the firewall as possible to maintain that balance.
What Usually Comes in a Conversion Kit?
When you start shopping for a 350z 2jz conversion kit, you'll notice they vary quite a bit in price. That's because some are just "starter" kits while others are "turn-key" solutions. At a minimum, you're looking at engine mounts and a transmission adapter plate.
The engine mounts are the stars of the show. They need to be beefy enough to handle the torque of a boosted 2JZ but precise enough to bolt directly to the 350Z subframe. Most high-quality kits use polyurethane bushings to keep the vibration down because, let's face it, solid mounts in a street car are a recipe for a headache and a rattling dashboard.
The Transmission Dilemma
One of the coolest parts about modern 350z 2jz conversion kit options is that they often allow you to keep your Nissan transmission. The CD009 transmission found in later 350Zs is legendary for its strength. It's often called the "poor man's V160." Instead of spending $10,000 on a Toyota Getrag 6-speed, you can spend a fraction of that on an adapter plate and a custom flywheel to mate the 2JZ to your existing Nissan gearbox.
This is a huge win for your budget. You get to keep your stock shifter location, your stock driveshaft (usually), and a transmission that we already know fits in the tunnel.
Dealing with the Oil Pan and Clearance
One thing that catches a lot of people off guard during this swap is the oil pan. The 2JZ came in several different configurations depending on what car it originally lived in—Supra, Aristo, or Chaser. For a 350Z swap, you're almost certainly going to need a rear-sump setup.
Many 350z 2jz conversion kit manufacturers will specify which pan you need, or they might even include a custom low-profile pan. If you try to use a front-sump pan, it's going to smash right into the Z's steering rack. It's these little details that make buying a kit so much better than trying to "wing it" with DIY brackets.
Wiring: The Part Everyone Dreads
Let's talk about the elephant in the room: the wiring. Getting a Toyota engine to talk to a Nissan body is… well, it's a process. Your 350Z uses a CAN-bus system for things like the tachometer, coolant temp gauge, and AC. If you just hack the wires together, you'll end up with a car that runs but has a dead dashboard.
The good news is that the market for the 350z 2jz conversion kit has evolved. You can now buy "jump" harnesses or plug-and-play kits that bridge the gap between the Toyota ECU and the Nissan chassis. If you're going for big power, you'll likely be using a standalone ECU like a Haltech or Link anyway. These units often have pre-configured maps for this exact swap, making the first startup way less stressful.
Cooling and Power Steering
Since the 2JZ is a long engine, space in the front of the engine bay gets tight. You'll probably have to ditch the mechanical fan for some high-flow electric fans. Most people using a 350z 2jz conversion kit also end up getting a tucked radiator or at least a very slim one to make sure there's room for the intercooler piping.
Power steering is another bridge you'll have to cross. Usually, it involves a custom high-pressure line that connects the Toyota pump to the Nissan rack. Again, many comprehensive kits will include these lines or at least the fittings you need to make them. It's much easier than standing in the middle of a hydraulic shop trying to explain what you're building to a confused clerk.
Is It a Weekend Job?
I'll be honest with you—unless you're a professional with a lift and a full shop, this isn't a "Saturday afternoon" project. Even with a high-end 350z 2jz conversion kit, there's a lot of "while I'm in there" work. You'll want to refresh the seals on the 2JZ, maybe upgrade the water pump, and definitely look at your fuel system. The 350Z has a returnless fuel system, while the 2JZ generally prefers a return-style setup with a regulator.
But don't let that discourage you. The beauty of using a kit is that the hard parts—the physical geometry of the car—are solved. You aren't guessing if the engine is level or if the hood will close. You're just following a roadmap that hundreds of other enthusiasts have already traveled.
Final Thoughts on the 350z 2jz conversion kit
At the end of the day, installing a 350z 2jz conversion kit is about creating something unique and incredibly capable. You're taking one of the best-looking Japanese sports cars of the 2000s and giving it the heart of a supercar slayer.
Yes, it's an investment. Yes, you'll probably scrape your knuckles and spend some late nights in the garage wondering why you didn't just leave the car stock. But the first time you hear that straight-six scream and feel the boost hit in a chassis as balanced as the 350Z, you'll know exactly why you did it.
Whether you're building a dedicated drift missile or just a wild street car to take to local meets, getting the right kit is the foundation of the whole project. Do your research, pick a kit with good reviews, and get to work. That 2JZ isn't going to install itself!
