How much does a 2006 Honda Civic engine cost?

Expect to pay about $900–$1,800 for a used 1.8L engine (parts only) for a 2006 Honda Civic, $3,000–$5,000 for a remanufactured long block, and more for Si and rare variants; fully installed, typical totals run $3,000–$7,000 depending on engine type, labor rates, and extras. Prices vary by mileage, warranty, and region, so understanding which Civic you have and what’s included is key before you buy.

What you’re actually buying when you buy a “2006 Civic engine”

The 2006 Civic lineup included several distinct powertrains, and the price depends heavily on which one you need. Most U.S. Civics use the 1.8L R18-series engine, while the Si uses a performance-oriented 2.0L K-series, the Hybrid pairs a 1.3L with IMA electric assistance, and the GX runs on compressed natural gas. Sellers may list short blocks, long blocks, or complete “pull-out” engines with accessories, each priced differently.

Know your trim and engine code

The first step is confirming which engine your car has and what configuration you need. This affects compatibility, price, and availability.

• DX/LX/EX (most models): 1.8L R18A1 (SOHC i-VTEC) — the most common and generally cheapest.
• Si: 2.0L K20Z3 (DOHC i-VTEC) — higher demand and price, performance components.
• Hybrid: 1.3L LDA-series (with IMA) — lower demand but hybrid-specific considerations.
• GX (CNG): 1.8L R18-series configured for natural gas — rare and usually pricier.

If you’re unsure, check your VIN, the under-hood emissions label, or consult a Honda parts catalog to avoid ordering an incompatible engine.

Typical price ranges in 2025

Below are current market ranges for parts-only engines (no installation). Actual quotes depend on mileage, source, warranty, core charges, and whether ancillary components are included.

• 1.8L R18A1 (DX/LX/EX):

  – Used, complete pull-out: $900–$1,800 (50–150k miles typical)

  – JDM import (low-mile): $1,200–$2,400 (may require sensor/bracket swaps)

  – Remanufactured long block: $2,400–$4,200 (+$300–$800 core)

• 2.0L K20Z3 (Si):

  – Used, complete: $1,800–$3,500 (condition and mods matter)

  – Remanufactured long block: $3,500–$6,000 (+core)

• 1.3L LDA-series (Hybrid):

  – Used long block: $700–$1,500

  – Remanufactured: $2,200–$3,800 (+core)

• R18-series CNG (GX):

  – Used: $2,000–$4,000 (scarce)

  – Remanufactured: variable; availability limited

New “crate” engines from Honda for 2006 models are generally discontinued; any new-old-stock, if found, often exceeds $5,000 before shipping and core fees.

Installation and total project cost

Engine replacement costs extend beyond the engine itself. Shops typically quote labor, fluids, and recommended preventive parts. Here’s what to expect.

• Labor: 12–20 hours for most Civics; at $110–$180/hour → $1,300–$3,600.
• Ancillary parts: gaskets, seals, coolant, belts, water pump, thermostat, engine mounts: $200–$800.
• Manual-trans cars: consider clutch kit if mileage is high: $300–$800 parts.
• Core charges (reman engines): $300–$800, refunded when your old engine is returned and accepted.

All-in, many owners see $3,000–$7,000 installed for non-Si models, with Si and rare variants trending higher due to engine cost and possible performance-specific parts.

Key factors that move the price up or down

Understanding why quotes differ helps you compare apples to apples and avoid surprises.

• Mileage and testing: Lower-mile or compression-tested used engines command more.
• Warranty length: Used units may carry 90 days to 1 year; remans often 3 years/100,000 miles.
• Completeness: A bare long block is cheaper than a complete pull-out with intake, injectors, manifolds, and accessories.
• Emissions spec: California vs. Federal and U.S.- vs. JDM-spec differences may require swapping sensors or manifolds.
• Regional availability: Prices vary by region and shipping distance/weight.
• Market demand: K20Z3 (Si) and CNG GX units are typically more expensive due to scarcity.

When comparing listings, confirm what’s included and the exact warranty terms to assess true value, not just sticker price.

Where to shop and what to ask

You can source engines from recyclers, national parts networks, JDM importers, or remanufacturers. Asking the right questions reduces risk.

• Sources: reputable salvage yards (via car-part.com), LKQ/Keystone, eBay Motors top-rated sellers, JDM importers, or remanufacturers like Jasper Engines, ATK/Vege, and Powertrain Products.
• Questions: exact engine code, donor vehicle mileage and VIN, compression/leakdown results, photos, included accessories, ECU compatibility, emissions spec, and warranty coverage/exclusions.
• Logistics: shipping cost, liftgate fees, return policy, and core return deadlines (for remans).

Document everything on the invoice—engine code, mileage, and warranty terms—so you’re protected if issues arise after installation.

Buying checklist (to avoid costly do-overs)

This step-by-step checklist can help you confirm compatibility and total cost before committing.

1. Verify your VIN and engine code; match emissions spec (CA vs. Federal).
2. Decide on used vs. reman based on budget, warranty needs, and vehicle condition.
3. Request test results (compression/leakdown) and donor VIN for used engines.
4. Confirm what’s included (long block vs. full pull-out) and any needed swaps (sensors, manifolds, brackets).
5. Get a written quote with engine price, shipping, taxes, core, and warranty.
6. Price installation with a trusted shop and budget for recommended “while-you’re-in-there” parts.
7. Schedule delivery to the installer and coordinate core return (if applicable).

Following these steps helps ensure the engine fits, the warranty applies, and the final bill aligns with your expectations.

Bottom line

For a 2006 Honda Civic, a typical 1.8L used engine runs roughly $900–$1,800, while remanufactured options are $2,400–$4,200 (often $3,000–$5,000 out the door with core and shipping). Si and rare variants cost more. Installed totals commonly land between $3,000 and $7,000, depending on labor rates and additional parts. Verify your exact engine, what’s included, and the warranty before you buy.

Summary

The cost of a 2006 Honda Civic engine depends on trim and condition: used 1.8L units typically cost $900–$1,800, remans $3,000–$5,000, with Si and GX engines higher. Expect $3,000–$7,000 all-in for parts and labor. Confirm engine code, emissions spec, inclusions, and warranty to avoid compatibility issues and unexpected costs.

What is the recall on the 2006 Honda Civic engine?

Yes, there was a significant extended warranty for 2006-2009 Honda Civics that addressed engine block cracks causing coolant leaks and potential overheating, though this was not technically a recall but rather a 10-year warranty extension. This issue affected many US-manufactured Civics, excluding the Si and Hybrid models, with Honda offering a free engine replacement if the problem was confirmed. To check your specific vehicle, you need to perform a VIN (Vehicle Identification Number) status inquiry on the Honda Owners Site or contact a dealer, as the warranty period has since expired for most affected vehicles. 
What the Issue Was

• Engine Block Cracks: . Opens in new tabSome 2006-2008 and early 2009 Civics (excluding Si and Hybrid models) developed cracks in the engine block. 
• Coolant Leaks: . Opens in new tabThese cracks caused engine coolant to leak, leading to overheating and potential engine failure. 
• Manufacturing Defect: . Opens in new tabThe defect was due to the engine casting becoming porous or thin in certain areas. 

The “Recall” (Warranty Extension) 

• 10-Year Warranty: Honda extended the warranty on the affected engine blocks for up to 10 years from the original purchase date, regardless of mileage.
• Free Replacement: The warranty covered a free engine block or full engine replacement at a Honda dealership if the issue was confirmed.
• Not for Salvage Vehicles: This warranty did not apply to vehicles that were declared a total loss by an insurer.

How to Check Your 2006 Civic

1. 1. Find Your VIN: Locate your 17-digit VIN on your vehicle’s registration or the bottom of the driver’s side windshield. 
2. 2. Perform a VIN Inquiry: 
   • Go to the Honda Owners Site VIN status checker. 
   • Contact a local Honda dealership. 
3. 3. Confirm Status: Your vehicle’s VIN status inquiry will show if it was affected and if the issue was addressed under the warranty program. 

Important Considerations

• Expired Warranty: The 10-year warranty period has expired for most 2006 Civics, so a dealership is unlikely to provide a free engine replacement at this point unless a new situation arises. 
• U.S.-Manufactured Affected: Only engines manufactured in the USA (VINs starting with “1HG”) were potentially affected by this issue. 
• Other Recalls: Your 2006 Civic may be subject to other, unrelated recalls, such as for airbags or cruise control systems. A VIN status check will also show these.
