How much horsepower does a 1990 Toyota 22R have?
In stock form, the 1990 Toyota 22R generally produced about 100 horsepower, with small variations depending on whether the engine was carbureted or fuel-injected and on the market tuning.
The 22R is a 2.4-liter inline-four used in Toyota pickups and 4Runners from the mid-1980s to the early 1990s. There were carbureted (22R) and electronic fuel injection (22R-E) versions, and horsepower is not identical across models or regions. This article outlines typical figures for 1990 configurations.
Overview of the 22R engine
The 22R is a 2.4-liter inline-four introduced in the mid-1980s, used in Toyota pickups and 4Runners. There were carbureted (22R) and electronic fuel injection (22R-E) variants. The exact horsepower depends on version and tuning for emissions, altitude, and fuel system.
Horsepower by version
The following figures are typical factory-rated values for common 1990 configurations in North America, noting that real-world horsepower varies with condition and upgrades.
- Carbureted 22R: about 105 horsepower (around 78 kW) at roughly 4,800 rpm; torque near 120 lb-ft (162 N·m) at a few thousand rpm.
- Fuel-injected 22R-E: about 105–110 horsepower (78–82 kW) with torque around 128–132 lb-ft (174–179 N·m).
These estimates reflect typical factory ratings for 1990-era North American vehicles with these engines. Market-specific numbers can vary slightly due to calibration, exhaust, and emissions controls.
How horsepower was measured and what affects it
Horsepower numbers are measured on dynamometers under specific test conditions and can differ from the SAE ratings listed in brochures. Factors such as altitude, emissions equipment, exhaust restrictions, cam timing, and maintenance can affect output. A well-maintained engine with proper timing and clean intake/exhaust will approach the published figures.
The 1990 22R's horsepower sits around the low-to-mid-100 hp range, with minor variation between carbureted and EFI configurations and market tuning. For most owners, you should expect roughly 100–110 hp in stock condition.
Summary: The 1990 Toyota 22R normally produced around 100–110 horsepower, with carbureted versions near 105 hp and EFI versions around 105–110 hp, depending on market and equipment.
