2JZ Engine Specs | GTE VS GE, What Cars Have a 2JZ Engine?
Let's talk about the engine that launched a thousand dream builds: the legendary Toyota 2JZ. If you've spent any time around import performance circles, you've probably heard people speak about this engine in almost mythical terms. And honestly, they're not wrong. Often called the LS swap of the import world, this inline-six masterpiece has earned every bit of its reputation, and today we're going to dive deep into what makes it so special.

Toyota 2JZ Engine Specs
Before we get into the nitty-gritty specs, let's address something: The 2JZ isn't just another engine. When Toyota engineers designed it in the early '90s, they essentially overbuilt everything. The cast-iron block, forged steel crankshaft, and robust cylinder head design weren't simply good engineering, they were over-engineered for the stock power levels. It's almost like Toyota's engineers knew exactly what enthusiasts would do with these engines decades later.

At its heart, the 2JZ is a 3.0-liter inline-six engine, measuring a perfect square bore and stroke of 86mm x 86mm. This combination gives it incredible balance and smooth power delivery. The engine block itself is a chunk of cast iron that could probably survive a nuclear blast, while the cylinder head is crafted from aluminum to save weight where it matters most. All in, a complete 2JZ tips the scales at around 498 pounds. Not exactly lightweight, but hey, good things come in heavy packages, right?
What Cars Have a 2JZ Engine?
The most famous home of the 2JZ-GTE was, of course, the MkIV Toyota Supra; the car that launched countless project builds and probably sold more than a few movie tickets (Fast and Furious, anyone?). But Toyota didn't stop there. The twin-turbo GTE also found its way into the Japanese-market Toyota Aristo V300, creating one of the most sophisticated sleeper sedans of its time.

The naturally aspirated 2JZ-GE, meanwhile, became the heart of several luxury vehicles, including the Lexus GS300, IS300, and their JDM counterparts, the Toyota Aristo and Altezza. This wider distribution is great news for builders today, as it means you've got more options when hunting for a base engine for your project.

How Much Horsepower Does a 2JZ Engine Have?
Here's where things get interesting, because the 2JZ story isn't just about stock numbers; it's about potential. But let's start with the basics. The crown jewel, the 2JZ-GTE, came from the factory with 320 horsepower in early models and 325 horsepower in later VVTi variants. Meanwhile, the naturally aspirated GE models put down a respectable 220 to 227 horsepower, depending on whether you're looking at the non-VVTi or VVTi versions.
2JZ GTE VS GE: A Tale of Four Engines
Now, let's break down the family tree, because there's more to the 2JZ story than just "turbo vs. non-turbo." There are four distinct variants, each with its own personality.

The original 2JZ-GTE (non-VVTi) is what most people think of when they hear "2JZ." It's the one that put the engine on the map and came in the turbo Supra in the US. With its sequential twin-turbo setup, forged internals, and 8.5:1 compression ratio, it was built for boost from day one. The oil-cooled pistons and beefier connecting rods tell you everything you need to know about Toyota's intentions.
When Toyota introduced the VVTi version of the GTE, they weren't just adding variable valve timing for better emissions. The updated head design and revised engine management improved low-end torque and overall efficiency, bumping output to 325 horsepower. More importantly, the VVTi system made the engine more responsive and easier to tune with modern engine management systems. Unfortunately, this engine never made it into the factory Supra in the US, but importing one is always an option, albeit an expensive one.
The 2JZ-GE story is equally interesting. The non-VVTi version was a solid performer with its higher 10:1 compression ratio and naturally aspirated setup. It might have "only" made 220 horsepower, but it delivered that power with the kind of smoothness that made Lexus' reputation for refinement.
When VVTi technology made its way to the GE, it brought more than just a power bump to 227 horses. The variable valve timing improved the engine's behavior across the entire rev range, making it more efficient and added torque down low. The intake design was updated, throttle response was enhanced, and the engine became even more suited to luxury car duty – while still maintaining that legendary 2JZ strength. Some might argue this is the best 2JZ to start with considering one can be had for under $500 and you get VVTi right out of the box. Throw some forged internals into the bottom end and you’ve got an 800 horsepower capable powerhouse.
How Much Horsepower Can a 2JZ Handle?
This is where the 2JZ legend really comes alive. That stock block? It's basically bombproof. With proper tuning and supporting mods, a stock 2JZ-GTE bottom end can reliably handle 800-1,000 horsepower. The GE isn't far behind. With proper modification, you can push a GE version to 400-500 horsepower before things get sketchy.

But that's just the beginning. Throw in some aftermarket forged internals, and you're looking at an easy 1,000 plus horsepower capability. The crazy part? With a fully built engine, including billet main caps and proper racing components, these engines have been known to handle 2,000 plus horsepower. There are even aftermarket billet block options out there pushing the 3,000hp mark. Though at that point, you're basically just using the 2JZ’s architecture rather than any Toyota components. Whether you're working with a stock setup or planning a single-turbo conversion, proper exhaust pipe selection and routing is crucial for optimal performance.
While the GTE comes with factory turbos, many builders opt for their own bespoke turbo kit setup when pushing for big power. Don't forget that proper (intercoolers)[https://www.speedwaymotors.com/shop/intercoolers~14-12-225-12616) are essential when running serious boost. The stock units won't cut it past 500hp.
How Much Does a 2JZ Engine Cost?
Let's talk money because building one of these beasts isn't cheap anymore. The days of finding a GTE for pocket change are long gone. These days, you're looking at $5,000 to $8,000 for a used GTE, while GE motors can still be found for $500 to $3,000 if you know where to look. Want a freshly rebuilt GTE? That'll be $8,000 to $12,000. And if you're going all-out with a race-built motor, prepare to shell out $15,000 or more.
Here's a pro tip before you start throwing money around: if you're planning a swap, start with a mock up engine block. They're a fraction of the cost of even a used 2JZ and let you figure out all your fitment issues before investing in the real thing. Trust us, it's a lot cheaper to discover clearance problems with a mock block than with your actual engine.
But remember, that's just the engine. You'll need a robust transmission that can handle the power, like a CD009 from the Nissan 350Z or the Tremec T56/Magnum. This often means sourcing the right transmission bell housing or using a bellhousing adapter to mate your chosen transmission to the 2JZ. Add in a standalone ECU, custom wiring harness, proper fuel system, and professional tuning, and you're looking at a serious investment. But hey, quality doesn't come cheap, right?
Can You Put a 2JZ in Any Car?
Here's the beautiful thing about the 2JZ: with enough fabrication skills and budget, it can fit almost anywhere. People have stuffed these engines into everything from Nissan S-chassis cars to BMW E36s, and even classic Datsun Zs. The aftermarket has developed solutions for many popular platforms, but you'll still need to think about motor mounts, transmission adapters, oil pan clearance, and cooling system packaging. Cooling is critical with these engines, especially in swap applications. You'll likely need to figure out what size radiator do I need for your specific setup, and often a universal radiator is the best solution for custom applications.
The engine's physical size can be a challenge; it's not exactly compact. But where there's a will (and a welder), there's usually a way. Just be prepared to do your homework on things like wiring harness modifications and engine management solutions before you start cutting up your car.
Before starting any swap, check an engine swap compatibility chart to understand the basic dimensions and constraints you'll be working with.
Why the 2JZ Still Matters
Twenty-plus years after its introduction, the 2JZ remains relevant not just because of its capabilities, but because it represents something special in automotive engineering. It's from an era when overbuilding was still a thing, when engineers could prioritize durability over cost-saving. The strength of the factory 2JZ block is very impressive, but what's even more impressive is that companies like Dart have since come out with even stronger options for the absolute madmen out there pushing beyond that 1,500 horsepower mark.
The 2JZ isn't just an engine, it's a blueprint for what's possible when engineering meets enthusiasm. Whether you're building a dependable daily driver or a 1,000-horsepower track weapon, the 2JZ provides a foundation that's tough to beat. Just remember, like any serious build, doing it right isn't cheap, but the results can be spectacular.
And if anyone tells you the 2JZ is overrated, well, there's probably a reason why these engines are still setting records and turning heads more than two decades after they first hit the streets. Although the Nissan RB is debatably a better engine in certain regards, good luck finding one stateside at a reasonable price. Some legends never die, they just get rebuilt with bigger turbos.
