How much HP does a B4 Subaru have?
There isn’t a single horsepower figure for a B4 Subaru; 'B4' is a four-door sedan designation used across several models, and horsepower depends on the engine and year. In general, NA B4s have roughly 100–170 hp, while turbocharged WRX/STI variants push into roughly 230–320 hp.
What the B4 Label Means
The B4 tag is a body-style designation that Subaru has used in various markets to denote a four-door sedan variant. It does not correspond to a single engine or power output. Instead, the horsepower you see on a B4 depends on the specific model line (Impreza, Legacy, etc.), the engine, and the generation. For example, naturally aspirated variants differ greatly from turbocharged WRX or STI versions, and later generations can surpass earlier ones in peak horsepower.
Why the distinction matters
Because buyers and sellers often reference a B4 by its trim and year rather than a single engine code, knowing the exact engine type (such as EJ20, EJ25, or FA-series engines) and the market (US, Europe, Japan) is the best way to determine the precise horsepower figure.
HP Ranges by Engine Family
Below is a basic guide to how horsepower varies across common B4 configurations. The numbers are approximate ranges intended to illustrate the spread across generations and markets.
- Naturally aspirated engines (1.6–2.0 L): roughly 100–170 hp, depending on displacement, year, and market.
- Turbocharged WRX/WRX STI variants: commonly range from about 230–320 hp, depending on generation and tuning. Early generations tended toward the 227–265 hp range, while many later models pushed higher figures.
- Performance-oriented variants and newer turbo setups: around 270–320 hp, with some STI configurations approaching the upper end of that range.
Concluding from these patterns, the horsepower of a B4 Subaru is not a fixed number. It hinges on the exact model, year, engine code, and market specifications. If you provide the specific year and engine code for the B4 you have in mind, I can give you a precise horsepower figure.
Summary
Summary: The B4 designation signifies a four-door sedan body style used across several Subaru lines, not a single engine. Horsepower varies widely—from about 100–170 hp in naturally aspirated versions to roughly 230–320 hp in turbocharged WRX/STI variants. For an exact figure, identify the exact model, year, and engine code of the B4 in question.
