The E30 BMW is a beloved platform among car enthusiasts, known for its lightweight chassis and engaging driving dynamics. When paired with the S50 engine, which originated from the E36 M3, the combination promises thrilling performance. In this article, we will explore real-world results regarding 0-60 times and drivability after an E30 S50 conversion.
Understanding the E30 and S50 Engine
The E30 series, produced from 1982 to 1994, is highly regarded for its classic styling and rear-wheel-drive layout. The S50 engine, a 3.0L inline-six, is known for its high-revving nature and robust power delivery. This combination is often sought after for track days and spirited driving.
Before diving into performance metrics, it’s essential to understand the modifications required for a successful conversion. Key components include:
- Engine mounts and brackets
- Wiring harness adaptation
- Cooling system upgrades
- Exhaust system modifications
Performance Metrics: 0-60 Times
One of the most anticipated metrics after an engine swap is the 0-60 mph time. This figure provides insight into the vehicle’s acceleration capabilities. Various E30 S50 conversions have yielded impressive results, often in the range of:
- Stock E30 325i: 7.5 seconds
- E30 with S50 conversion: 5.5 to 6.0 seconds
These times can vary based on several factors, including vehicle weight, tire selection, and tuning. The reduction in acceleration time is a testament to the power increase provided by the S50 engine, which delivers approximately 240 horsepower compared to the E30’s original 140 horsepower.
Drivability and Daily Use
While performance figures are crucial, drivability is equally important for those considering an E30 S50 conversion. Many drivers report that the S50 maintains a level of refinement that makes it suitable for daily driving. Key aspects of drivability include:
- Smooth power delivery across the RPM range
- Improved throttle response
- Compatibility with E30’s existing transmission options
Drivers have noted that the S50 engine feels at home in the E30 chassis, providing a balance of performance and comfort. The conversion does require attention to detail, particularly in tuning and setup, to ensure reliability and longevity.
Real-World Testimonials
Hearing from those who have completed the conversion can provide valuable insights. Here are some testimonials from E30 owners who have made the switch to an S50 engine:
- “The power increase is incredible. I went from a fun car to a real performance machine!”
- “I was surprised at how well the car drives daily. It’s comfortable and responsive.”
- “The swap was challenging, but the end result was worth every effort.”
Conclusion
In conclusion, the E30 S50 conversion offers a significant boost in performance while maintaining drivability. With 0-60 times dropping considerably and the engine’s smoothness enhancing daily use, this swap is a popular choice among enthusiasts. Whether for track use or as a daily driver, the E30 with an S50 engine provides an exhilarating experience that is hard to match.
