The 1994 Prelude Si uses Honda’s 2.2-liter F-series inline-4 engine (the F22A family), a non-VTEC four-cylinder commonly delivering roughly 140–150 horsepower depending on market and emission tuning.
Engine family and specifications
The following details summarize the US-market engine typically found in the 1994 Prelude Si and its closest 4th-generation peers.
Before listing the key specifications, note that the Prelude Si in 1994 was aligned with Honda’s 2.2-liter F-series powerplant lineage. The exact output can vary slightly by market and model year due to emissions equipment and tuning.
- Engine code and displacement: 2.2-liter inline-4, part of the F22A family (approximately 2,194 cc).
- Configuration: Double Overhead Camshaft (DOHC) with four cylinders.
- Power output: generally around 140–150 horsepower, depending on market and tuning.
- Torque: typically in the neighborhood of 128–140 lb-ft (174–190 Nm).
- Lighting and emissions: tuned for US market standards of the era, with carburetion replaced by multi-point fuel injection.
- Transmission options: commonly paired with a 5-speed manual; some markets offered a 4-speed automatic.
- Technology note: this engine is not the VTEC variant that appeared in later Prelude generations; VTEC-oriented powerplants appeared later in Honda’s lineup and in subsequent Prelude generations.
These specifications provide a general picture of what powered the 1994 Prelude Si. Always verify the exact engine code and specification on a specific vehicle, as there were regional variations and minor revisions during the model year.
Context and variations by market
Across global markets, the 2.2-liter F-series engine family underpinned several Prelude configurations in the 4th generation. While the US-spec Prelude Si commonly used the non-VTEC F22A variant, other regions sometimes used closely related F-series engines with minor tuning differences to meet local emissions and fuel requirements. Over the model’s run, Honda progressively shifted its lineup toward more advanced powertrains in later years, but the 1994 Prelude Si stayed anchored to the familiar 2.2L F-series platform.
Notes for buyers and restorers
If you’re evaluating a 1994 Prelude Si, check the engine code on the block (F22A or a close variant) and review service history for timing belt/chain maintenance, valve clearance checks, and fuel-injection service. Mileage and regional tuning can affect output and longevity, so a pre-purchase inspection is valuable.
Summary
In brief: the 1994 Honda Prelude Si is powered by a 2.2-liter inline-4 from Honda’s F-series (the F22A family), offering roughly 140–150 hp depending on market. This engine represents the era’s core performance hardware for the US-market Si model, prior to Honda’s later introduction of more advanced VTEC variants in the Prelude lineup.
