What Cars Have a 22R Engine?
The Toyota 22R powered a range of vehicles through the 1980s and early 1990s, though it’s best known for its role in Toyota’s tough trucks and SUVs.
- Toyota Pickup / Hilux (1981–1995): The most common application, where the 22R built its reputation for durability in work and off-road use.
- Toyota 4Runner (1984–1995): Early generations of Toyota’s compact SUV relied on the 22R/22RE, making it popular among adventurers.
- Toyota Celica (1981–1982): Some early ’80s Celicas offered the 22R as a reliable four-cylinder option.
- Toyota Corona / Carina (select markets): Used in certain export models, showing the engine’s versatility.
Its widespread use in Toyota’s pickup and 4Runner lineup is the main reason the 22R is remembered as a tough, long-lasting workhorse.
How Much Horsepower Does a 22R Have?
The Toyota 22R was never about raw power—it was built for dependability and usable torque.
- Horsepower Range: Typically between 96–108 hp, depending on the model year and emission regulations in different markets. Early versions in the 1980s made closer to 96 hp, while later models reached around 105–108 hp.
- Torque Output: Around 128 lb-ft, which gave Toyota pickups and 4Runners enough low-end grunt for hauling loads and tackling rough terrain.
- Performance Focus: Rather than high-revving horsepower, the 22R was tuned for low-end torque, making it especially useful for off-road driving, towing small trailers, and carrying heavy cargo.
By today’s standards, those numbers may seem modest, but in the 1980s the 22R delivered exactly what light trucks and SUVs needed: reliable, steady power that prioritized endurance over speed. This balance of simplicity and strength is a big part of why the 22R remains so respected among Toyota enthusiasts.
How Long Does a 22R Last?
One of the biggest reasons enthusiasts admire the 22R is its remarkable longevity.
- Average Lifespan: With regular maintenance, most 22Rs easily run 250,000–300,000 miles.
- High-Mileage Examples: Many owners report engines lasting 400,000 miles or more before needing a major rebuild, a testament to the 22R’s simple yet durable design.
- Key Maintenance: Routine oil changes, keeping the cooling system in good shape, and replacing the timing chain before it wears through the guides are essential for long life.
- Why It Lasts: The 22R is an understressed engine with modest horsepower, strong internals, and a straightforward design, which reduces the chances of catastrophic failure.
For decades, owners have shared stories of their 22R-powered trucks still running reliably after decades of use—often outlasting the vehicle’s body and frame. It’s this reputation for endurance and dependability that makes the 22R legendary among Toyota fans.
22R vs 22RE vs 22R-TE: What’s the Difference?
As Toyota refined its R-series lineup, the 22R evolved into the fuel-injected 22RE and later into the turbocharged 22R-TE. All three share the same 2.4L foundation, but they differ in fueling, power output, and complexity.
| Feature | 22R (Carbureted) | 22RE (EFI) | 22R-TE (Turbo EFI) |
|---|---|---|---|
| Fuel System | Carbureted | Electronic Fuel Injection (EFI) | EFI with Turbocharger |
| Horsepower | ~96–108 hp | ~105–115 hp | ~135 hp |
| Torque | ~128 lb-ft | ~140 lb-ft | ~173 lb-ft |
| Efficiency | Modest, carb tuning needed | Better fuel economy, smoother response | More power, slightly less efficient |
| Maintenance | Simple, fewer electronics | Slightly more complex | More complex, turbo adds maintenance needs |
| Reliability | Excellent | Excellent | Good, but turbo setup less durable long-term |
Key Takeaways:
- The 22R is the simplest, with a carburetor that makes it easy to repair in the field but less efficient.
- The 22RE improved drivability and efficiency with fuel injection, making it a better everyday option.
- The 22R-TE added a factory turbo, boosting power and torque significantly, but it was only produced from 1986–1988 and is less common. While fun and more powerful, it didn’t achieve the same legendary durability as the naturally aspirated versions.
Verdict: If you want simplicity, the 22R is the best choice. For a balance of efficiency and reliability, go with the 22RE. If you’re after rarity and extra performance, the 22R-TE is worth mentioning—but expect higher maintenance and fewer available parts today.
Common Problems with the 22R Engine
Even a legendary engine has its weak spots. While the 22R is famous for reliability, long-term owners have identified a few recurring issues:
- Timing Chain Wear: One of the most common problems. The original plastic timing chain guides often wear or break around 80,000–120,000 miles, leading to chain rattle and, if ignored, potential damage to the timing cover or water jacket. Many owners upgrade to steel-backed guides during rebuilds to permanently fix the issue.
- Head Gasket Failure: After very high mileage, it’s not unusual for the 22R to blow a head gasket. Overheating and aging gaskets are typical culprits. Fortunately, replacement is straightforward, and quality aftermarket gaskets are widely available.
- Oil Leaks: With age, valve cover gaskets, front/rear main seals, and oil pan gaskets may seep. While messy, these leaks are rarely catastrophic and are easy to repair with routine maintenance.
- Carburetor Issues: On carbureted 22Rs, the carb can become clogged or wear internally, causing rough idling, hesitation, or hard starting. Many owners either rebuild the factory carb or swap to aftermarket options for better reliability.
Real-World Notes:
- Many 22R owners report that once the timing chain guides are replaced with metal versions, the engine can run another 150,000+ miles trouble-free.
- Enthusiasts on Toyota forums often joke that the 22R’s “oil leak” is more of a feature than a flaw, since it rarely impacts performance.
- For off-roaders, the carburetor can be a weak spot on steep climbs, which is why some choose to convert 22Rs to EFI or upgrade to a Weber carb for better performance.
Fortunately, every one of these issues is well-documented, inexpensive to fix, and supported by a massive aftermarket community. With proper maintenance, these problems are minor compared to the engine’s overall durability.
Upgrades and Rebuild Options
Thanks to its long production run and loyal fan base, the 22R enjoys a huge aftermarket scene. Parts are easy to find, and upgrades range from mild to wild.
- Performance Upgrades: Popular mods include Weber carb swaps, performance cams, headers, and EFI conversions. Enthusiasts sometimes go further with turbo or supercharger kits, though reliability usually takes priority over raw power.
- Rebuild Kits: Complete kits with pistons, gaskets, bearings, and upgraded timing components are widely available, making it simple to refresh an old 22R for another 200,000+ miles.
- Swaps and Off-Road Builds: The 22R/22RE remain favorites for off-roaders who value torque, simplicity, and bulletproof reliability, making them common choices in Hilux, Pickup, and 4Runner projects.
Overall, the 22R is more than just a stock engine—it’s a platform for restoration, performance tuning, and off-road adventure.
Buying a Toyota 22R Engine
Today, the 22R is no longer produced new, but it’s still widely available as used, rebuilt, or remanufactured units. Its popularity among Toyota enthusiasts means sourcing one isn’t difficult, though condition can vary.
Where to Find Them:
- Engine rebuilders and aftermarket suppliers often sell remanufactured 22Rs with upgraded timing components.
