Key takeaways

• The 1JZ is a 2.5-liter twin-turbo inline six, built by Toyota from 1990 to 2007
• It came in three versions: non-VVTi twin-turbo, VVTi single turbo, and the naturally aspirated 1JZ-GE.
• Stock output sits around 280 PS across the turbo versions
• Common in the Toyota Chaser, Mark II, Cresta, and Soarer
• Costs less than a 2jz, making it a solid choice for builds under 500 horsepower

What is the Toyota 1JZ-GTE?

The 1JZ-GTE is a turbocharged inline six from Toyota's JZ engine family. Toyota built it to replace the older M series sixes, and it powered Japan's mid-size luxury and sport sedans through the 1990s and 2000s. It's smooth, it revs cleanly, and it responds well to boost, which is why it still shows up in drift builds today.

Where it sits in the JZ family

Think of the 1JZ as the smaller sibling to the 2JZ. Both share a similar block design and bore size, but the 2JZ-GTE gets a longer stroke and more displacement. If you want the full breakdown, we cover it in the 1JZ vs 2JZ comparison.

Production years

Toyota built the 1JZ-GTE from 1990 through 2007. The first generation ran twin turbos, and Toyota switched to a single turbo setup partway through the engine's life. We'll cover the split below.

1JZ-GTE specs

Here's a quick look at how the versions compare.

Non-VVTi twin turbo

The early 1JZ-GTE runs two small CT12A turbos in parallel. That setup spools fast and gives you early power, though the ceramic turbine wheels aren't as durable as later steel units. Displacement is 2,492 cc across every version.

VVTi single turbo

Toyota reworked the head in 1996 under its BEAMS program and moved to a single CT15B turbo. Torque jumps noticeably at low rpm, and the engine runs a bit more efficiently as a result. Power stays close to the same 280 PS, but it arrives with less lag.

1JZ-GE naturally aspirated

The 1JZ-GE skips the turbo entirely. Early versions made around 170 PS, and Toyota added VVTi in 1995 to bump that closer to 200 PS. It's not the engine people import for power, but it's a solid, low-stress option if you're after reliability over boost.

What cars came with a 1JZ?

The 1JZ engine shows up across several Toyota and Lexus platforms.

• Toyota Chaser, Mark II and Cresta (JZX81, JZX90, JZX100, JZX110)
• Toyota Soarer (JZZ30)
• Toyota Supra JZA70, sold only in Japan and Australia
• Toyota Aristo and select Crown and Verossa models

Toyota Chaser, Mark II and Cresta

These X chassis cars are the most common source for a 1JZ swap. They're Rear Wheel Drive, they're plentiful, and parts support is strong. If you're looking at a Toyota Chaser for sale, JZX100 models from the VVTi era are usually the sweet spot for price and reliability.

Toyota Soarer

The Soarer got the 1JZ-GTE from day one back in 1991. It's a heavier, more luxury-focused platform than the Chaser, so expect a slightly different driving feel.

Toyota Supra and Aristo

The JZA70 Supra used a 1JZ in Japan and Australia before the later MK4 Supra moved to the larger 2JZ. The Aristo, which became the Lexus GS in the US, ran both 1JZ and 2JZ depending on trim.

1JZ vs 2JZ: which should you buy?

This is probably the most common question we get, and honestly, it depends on what you're building.

Displacement and torque

The 2JZ displaces 3.0 liters against the 1JZ's 2.5 liters, so it naturally makes more torque and has more headroom for big power. If your build plan involves 500+ horsepower, the 2jz gte for sale listings are worth a look.

Cost difference

The 1JZ usually costs less to import than a 2JZ, partly because demand for 2JZ swaps is higher right now. If your budget is tight and you don't need huge power, that gap matters.

When the 1JZ is the smarter choice

For drift builds, daily Rear Wheel Drive swaps, or anything under 500 horsepower, the 1JZ does the job at a lower price point. It's also a bit lighter than the 2JZ, which some drift builders prefer for weight balance.

Front sump vs Rear sump

Why it decides fitment

Sump location determines how the oil pan clears your chassis and crossmember. Get this wrong, and your swap won't bolt in without extra fabrication.

How to tell which you are looking at

Look at where the oil pan sits relative to the bell housing. A front sump pan sits toward the front of the engine, while a rear sump sits closer to the transmission. If you're unsure, ask the seller before you buy, or check the chassis code against known fitments.

How much power can a 1JZ handle?

The stock bottom end is generally considered solid up to around 400 to 500 horsepower on stock internals, assuming supporting mods and a tune. Some builders push further, but reliability starts to depend heavily on how the engine was maintained before import. That's one more reason compression testing before purchase matters so much.

Transmission options

R154

The R154 is the 5-speed manual that paired with many 1JZ-GTE cars. It's a well-proven gearbox and a common choice for swaps that want a manual setup. Browse our current stock of JDM Toyota transmissions if you need one for your build.

Automatic options

Most 1JZ-GE and later VVTi cars came with an automatic, typically a 4-speed unit. If you're keeping the car closer to stock, the factory automatic is fine for street use.

Common issues and what to check

A few things are worth inspecting before you commit to a 1jz:

• Turbo condition, especially on the twin-turbo ceramic units

• Coolant crossover pipe corrosion, a known weak point on these engines

• Signs of prior overboost or a poorly done tune

• Oil consumption, which can point to worn rings or seals

What a 1JZ costs in 2026

Pricing varies by mileage, condition, and whether the engine comes with the transmission and harness.Non-VVTii units tend to run a bit less than VVTi versions, since VVTi engines make more usable low-end torque. Complete swap packages with the R154 or automatic will cost more than a bare long block.

Frequently asked questions

Why is the JZ family so special?

The JZ inline-six lineup earned its reputation from being genuinely overbuilt for its era. Toyota engineered both the 1JZ and 2JZ with strong bottom ends, which is why they hold up well under boost decades later.

What cars have a 1JZ engine?

Mainly the Toyota Chaser, Mark II, Cresta, Soarer, early Supra, and Aristo. A few Crowns and Verossa trims got it as well.

How much power can a 1JZ handle?

Most builders see 400 to 500 horsepower as a safe ceiling on stock internals, though results vary based on the engine's history and how it's tuned.

Is a 1JZ or 2JZ better?

Neither is strictly better. The 2JZ gives you more displacement and headroom, while the 1JZ costs less and suits builds under 500 horsepower. For the full breakdown, see the 2JZ family guide.
