What size turbo is in the Honda Accord?
There isn’t a single turbo size for the Honda Accord—the car is offered with two distinct turbocharged engines, and Honda does not publish a specific compressor-wheel size in public specs.
Across generations, the Accord has been offered with two turbocharged engines in many markets: a 1.5-liter turbo and a bigger 2.0-liter turbo, with different power outputs and transmission pairings. Exact turbocharger measurements are generally not disclosed by Honda in official materials, and sizes can vary by model year and region.
Turbo engine options in the Accord
The two engines differ in displacement, boost behavior, and performance tuning. Here are the standard US-market options and their typical outputs.
- 1.5-liter turbocharged inline-4 (1.5L VTEC Turbo) — up to 192 horsepower and 192 lb-ft of torque, typically paired with a CVT in most trims.
- 2.0-liter turbocharged inline-4 (2.0L Turbo) — up to 252 horsepower and 273 lb-ft of torque, typically paired with a 10-speed automatic in U.S. models.
These numbers reflect recent model years; depending on market and year, trims and transmissions can differ. Check the window sticker or VIN-specific build data for exact figures on a given car.
What “turbo size” means in practice
Honda does not publish precise turbocharger dimensions (compressor wheel size, turbine trim, or A/R ratio) for the Accord. The practical takeaway for owners is that the 1.5L engine uses a smaller turbo designed for good low- to mid-range torque and efficiency, while the 2.0L engine uses a larger turbo tuned for higher peak power. The exact size varies by engine family and year and is part of Honda’s internal engineering details.
How to confirm the exact turbo hardware on your car
To determine the precise turbocharger used on a specific Accord, you can:
- Check the engine code on the hood plate or the VIN-decode and then look up service documentation for that code (for example, L15B7 for the 1.5L and the 2.0L's corresponding code).
- Consult the dealership or Honda technical service bulletins that list parts and equipment by VIN.
- Inspect the engine bay for the turbocharger unit and note any part numbers on the housing, then cross-reference with parts catalogs.
For most owners, the practical answer is that there isn’t a single “turbo size” you need to know; the choice is between two turbocharged engines with different performance profiles.
Summary
The Honda Accord uses two turbocharged engines rather than one fixed turbo size: a 1.5-liter turbo and a larger 2.0-liter turbo. Honda does not publish exact turbocharger sizes, and the precise hardware can vary by year and market. For a given car, check the VIN or ask a dealer to identify the exact engine and turbo hardware.
