What Engine Swaps Are Available for the 1NZ-FE?
The Toyota 1NZ-FE engine, best known for powering small cars like the Toyota Yaris, Vios, and Echo, is a lightweight and fuel-efficient 1.5L inline-4 engine. While it’s dependable and economical, it doesn’t exactly scream performance. That’s why many car enthusiasts consider swapping it out for something more powerful or better suited to their driving goals. But what are the best engine swap options for the 1NZ-FE? Let’s dive into the most popular and feasible swaps, what to consider before making the jump, and how each option stacks up.
1. 2ZZ-GE – The High-Revving Toyota Favorite
One of the most popular upgrades for 1NZ-FE owners looking for a naturally aspirated performance engine is the 2ZZ-GE. Found in the Toyota Celica GTS, Lotus Elise, and Corolla T-Sport, the 1.8L 2ZZ-GE is famous for its high-revving nature and VVTL-i (Variable Valve Timing and Lift with intelligence) system.
- Power Output: ~180 hp
- Pros: Factory Toyota compatibility, high redline (8,200 RPM), lightweight
- Cons: Requires custom mounts, ECU and wiring work
This swap keeps things in the Toyota family, and because the 2ZZ is also an inline-4, it can be squeezed into the engine bay of a 1NZ chassis with some fabrication. For aggressive street driving and even track use, it’s a great option.
2. 1NZ-FTE – The Turbocharged Cousin
If you’re looking for a less invasive swap and want to stick with the 1NZ family, consider going turbo. The 1NZ-FTE is essentially a turbocharged version of the 1NZ-FE. While Toyota never officially released a factory 1NZ-FTE, many tuners have successfully turbocharged the 1NZ-FE with aftermarket kits or parts from other Toyota turbo platforms.
- Power Output: Can safely reach 150–200+ hp with proper tuning
- Pros: Retains original engine block, less complexity in wiring and fitment
- Cons: Requires tuning expertise, potential reliability concerns if not done correctly
This option is great for those who want more power without completely changing the engine. It also keeps weight down, which is a big bonus in small cars.
3. 3SGTE – Legendary Turbo Power
If you’re after serious performance and don’t mind going big, the 3SGTE is a well-known turbocharged inline-4 from cars like the Toyota MR2 and Celica GT-Four. It’s one of Toyota’s most iconic engines, with a robust iron block and high power potential.
- Power Output: 200–300+ hp (stock to modified)
- Pros: Massive aftermarket support, proven reliability
- Cons: Heavier than 1NZ, major fabrication needed, drivetrain upgrades likely
Swapping a 3SGTE into a car originally powered by a 1NZ-FE is not for the faint of heart. You’ll need custom mounts, a new transmission, upgraded brakes, and probably a new suspension setup. But if you’re building a race car or just want to dominate the streets, it’s a wild but thrilling option.

4. K20/K24 – Honda’s Performance Bargains
Yes, it’s sacrilege to put a Honda engine in a Toyota — but performance-wise, the K20 or K24 swap can’t be ignored. Honda’s K-series engines are widely available, powerful, and have a massive tuning community.
- Power Output: 200–250+ hp stock
- Pros: Bulletproof reliability, cheap and accessible parts, great aftermarket support
- Cons: Custom fabrication, non-Toyota wiring, potential purist backlash
It’s a popular choice in the tuner world due to its performance per dollar. Just be prepared for the extra wiring work and potential transmission integration challenges.
5. 2AR-FE – The Bigger Toyota Four
For those looking for torque and displacement in a modern package, the 2.5L 2AR-FE is worth considering. It’s found in cars like the Toyota Camry and RAV4, and with the right transmission and ECU setup, it can offer excellent power gains over the 1NZ-FE.
- Power Output: ~175–180 hp, more with turbo
- Pros: Modern engine, reliable, good torque
- Cons: Larger size may require fabrication, needs standalone ECU for swap
This is a newer engine option that’s starting to gain attention in the Toyota tuning scene. It’s a good mix of power and modern engine design without going to forced induction — unless you want to.
Final Thoughts
The 1NZ-FE is a solid engine for commuting and fuel efficiency, but when it comes to performance, an engine swap opens up a world of possibilities. Whether you want a Toyota-based powertrain like the 2ZZ-GE or want to push the limits with a 3SGTE or K20, there’s an option for every budget and goal. Just be sure to consider the overall cost, fabrication required, and how the new engine will affect daily drivability, reliability, and legality in your region.
Before committing to any swap, do your research, set a realistic budget, and talk to others who’ve done similar builds. A well-thought-out and executed 1NZ-FE exchange can turn your boring commuting into something genuinely thrilling.
