Dowel pinning helps prevent unwanted movement between engine components during high-load operation, making it particularly beneficial for:
- Turbocharged setups
- Track day vehicles
- Drift applications
- High-horsepower street builds
- Long-term durability
Many experienced rotary builders consider dowel pinning a worthwhile investment when preparing a performance-oriented engine.
