### **Pros and Cons of Buying a Used Subaru 303.SU1P20 Crankshaft (2019 2023 Crosstrek 2.0L Engine)**
#### **Overview**
The **2.0L FB20 engine** (code **303.SU1P20**) in the **2019 2023 Subaru Crosstrek** is a reliable, turbocharged boxer-four known for its performance, fuel efficiency, and AWD capability. However, like any engine, it has strengths and potential drawbacks, particularly regarding the **crankshaft** a critical component that may require replacement due to wear, damage, or failure.
---
### **Pros of Considering a Used Crankshaft for This Engine**
1. **Proven Reliability of the FB20 Engine**
- The **FB20** is Subaru s most advanced 2.0L turbo engine, featuring direct injection, variable valve timing, and a high-stress turbocharger. While not as bulletproof as older naturally aspirated Subaru engines, it has shown **good longevity** when maintained properly.
- Many owners report **150,000 miles** with minimal issues if serviced regularly (oil changes, timing belt replacements, etc.).
2. **Performance and Efficiency**
- The **turbocharged setup** provides **158 200 HP** (depending on model year and trim), making it more powerful than non-turbo Subaru engines.
- **Fuel economy** is strong for an AWD SUV, averaging **24 28 MPG combined** (better than many competitors).
- The **boxer engine layout** offers a low center of gravity, improving handling and stability.
3. **AWD Capability**
- The Crosstrek s **Symmetrical AWD** is one of the best in its class, making it ideal for **snow, mud, and off-road conditions**.
- The **FB20 s torque delivery** (especially with the turbo) works well with AWD for better traction.
4. **Aftermarket and Mod Potential**
- The **FB20 is highly modifiable**, with aftermarket support for **turbo upgrades, cold air intakes, exhausts, and ECU tuning**.
- Tuners like **Apexi, SubaruSpecialist, and JB4** offer software upgrades to boost power and responsiveness.
- **Remanufactured crankshafts** (from brands like **Fel-Pro, Mahle, or OE replacements**) are widely available and often cost-effective.
5. **Subaru s Warranty and Resale Value**
- The **2019 2023 Crosstrek** retains **strong resale value** compared to many competitors, partly due to Subaru s reputation for durability.
- Some **extended warranties** (if purchased from a dealership) may cover the crankshaft or related components.
6. **Common Crankshaft Issues Are Manageable**
- The **main concern with the FB20 crankshaft** is **wear over high mileage** (typically **150,000 miles**), leading to **oil leaks, rod bearing failure, or main bearing wear**.
- However, **early signs (knocking, oil consumption, check engine lights)** can be caught before catastrophic failure.
- **Replacement costs** ( $1,500 $3,000 for labor parts) are **lower than a full engine swap**, making it a viable repair.
---
### **Cons and Potential Drawbacks**
1. **Higher Maintenance Costs Than Naturally Aspirated Engines**
- The **turbocharger, intercooler, and fuel system** require **more frequent attention** than a non-turbo engine.
- **Oil changes every 5,000 7,500 miles** (or as recommended) are **critical** to prevent sludge buildup and turbo damage.
- **Timing belt and water pump replacement** (every **105,000 miles**) is **mandatory** skipping this can lead to **catastrophic engine failure**.
2. **Crankshaft and Rod Bearing Wear Over Time**
- The **FB20 s crankshaft** is **stressed by turbo boost**, leading to **premature wear** in high-mileage examples.
- **Common symptoms of crankshaft issues:**- **Knocking or rattling** (especially under load).
- **Oil leaks** (from crankshaft seals or main bearing caps).
- **Check Engine Light (P0011, P0014, P0017)** for timing or rod bearing issues.
- **Blue smoke from exhaust** (indicating oil burning).
- **Replacement cost** is **high** ( $1,500 $3,000), and **labor-intensive** (requires removing the engine).
3. **Turbocharger and Fuel System Reliability**
- The **turbocharger** is a **common failure point** if oil changes are neglected.
- **Fuel injectors** can clog over time, leading to **rough idling or misfires**.
- **Carbon buildup** in the intake valves (common in turbo engines) may require **intake valve cleaning** ( $500 $1,000).
4. **Recall and Software Issues**
- Some **2019 2021 models** had **recalls related to the turbocharger** (Subaru issued a **free turbo replacement** for certain VINs).
- **ECU glitches** (e.g., **P0420 catalytic converter codes**) can occur, requiring **software updates or sensor replacements**.
5. **Higher Repair Costs Than Competitors**
- Subaru **parts and labor** are **more expensive** than many Japanese brands (Toyota, Honda, Mazda).
- **Specialized tools** (e.g., for timing belt removal) add to repair costs.
6. **Potential for Early Failure in High-Mileage Examples**
- Some **2019 2020 FB20 engines** (especially in **high-performance trims**) have reported **premature rod bearing wear** due to **design refinements**.
- **2021 models** improved with **stiffer crankshafts and better bearings**, but **early examples may still have issues**.
---
### **Key Considerations Before Buying a Used Crankshaft or Engine**
1. **Check the Engine s History**
- **Service records** are **essential** look for **regular oil changes, timing belt replacements, and turbo inspections**.
- **Avoid engines with:**- **No timing belt replacement** (if over 105,000 miles).
- **History of oil leaks** (indicates potential crankshaft seal failure).
- **Knocking noises** (could mean rod or main bearing wear).
2. **Inspect for Crankshaft-Specific Issues**
- **Listen for knocking** (especially under acceleration) during a **test drive**.
- **Check for oil leaks** around the **crankshaft seals and main bearing caps**.
- **Look for check engine lights** (scan for **P0011, P0014, P0017, P0128** related to timing or rod bearing issues).
- **Test oil consumption** if the engine **burns oil excessively**, the crankshaft may be worn.
3. **Compare Costs: Repair vs. Replacement**
- **Crankshaft replacement** ( $1,500 $3,000) is **less expensive than a full engine swap** ( $4,000 $6,000).
- **Remanufactured crankshafts** (from **Fel-Pro, Mahle, or OE**) are **reliable** if sourced from a **reputable supplier**.
- **DIY vs. Professional Installation** while **possible for experienced mechanics**, most prefer **dealer or specialty shops** for crankshaft work.
4. **Consider Alternative Solutions**
- If the **crankshaft is beyond repair**, a **remanufactured engine** (from **Subaru, Fel-Pro, or Mahle**) may be a **better long-term solution**.
- **Engine swaps** (e.g., **FB25 for more power**) are **popular** but require **additional modifications**.
5. **Buy from a Reputable Source**
- **Dealerships** (with **Certified Pre-Owned programs**) offer **better warranties** but at a premium.
- **Private sellers** can be **cheaper** but **riskier** always **get a pre-purchase inspection**.
- **Auction houses** (e.g., **Copart, IAA**) sell **salvage engines** at a discount, but **quality varies**.
---
### **Final Recommendation**
#### **If You Need a Crankshaft for a 2019 2023 Subaru Crosstrek FB20:** **Proceed with a used crankshaft replacement if:**- The **engine has under 150,000 miles** and **maintenance records are complete**.
- **No knocking, oil leaks, or check engine lights** are present
