The 1994 Honda Prelude Si is powered by a 2.2-liter inline-four from Honda’s F-series, most commonly the F22A1 in US-spec cars, delivering roughly 140–150 horsepower. The exact variant can vary by market and production run.
Engine overview
The fourth-generation Prelude (1992–1996) offered sportier trims such as the Si with a 2.2L family engine. While the core specification for many US-market Si models centers on the 2.2L F-series engine, regional variations did occur, and some markets used slightly different codes within the same displacement class. The key takeaway is that the Si relies on a non-VTEC 2.2L inline-four rather than a larger or VTEC-equipped powerplant.
US-spec details
Below are the typical characteristics you would find on most US-market 1994 Prelude Si examples:
- Engine code: F22A1 (US-spec); some export/late-production examples may use F22A4 or related variants
- Displacement: 2.2 liters (approximately 2,184–2,199 cc)
- Configuration: Inline-four, non-VTEC
- Power output: roughly 140–150 horsepower
- Torque: around 128–140 lb-ft
- Redline: typically in the vicinity of 6,000–6,500 rpm
- Transmission options: 5-speed manual standard; 4-speed automatic available on some examples
These figures reflect the common US-market specification for the 1994 Prelude Si; variations can occur by year, production batch, and regional market. Always verify the exact engine code on your vehicle for precise data.
How to verify the exact engine in your car
To confirm the engine variant in your specific Prelude Si, use these checks and identifiers:
- Inspect the engine block for the code stamp (look for F22A1, F22A4, or nearby variants)
- Check the under-hood emission label or ECU part number for engine matching information
- Cross-check your VIN with the build sheet to confirm trim and engine options for your market
- Look for visual cues (e.g., intake plumbing, valve cover markings) that align with F-series 2.2L paperwork
Knowing the exact engine code helps ensure you source the correct parts and service information for your specific Prelude Si.
Summary
In summary, the 1994 Prelude Si typically uses a 2.2-liter inline-four from Honda’s F-series, most often the F22A1 in the United States, with approximately 140–150 hp and a non-VTEC design. Engine codes and exact specifications can vary by market and production year, so verifying the engine code on your car is the best way to confirm the precise configuration.
