Best Performance Upgrades for S50 Swapped E30: Exhaust, Ecu, and Intake Boosts

by

The BMW E30 is a classic platform that has captured the hearts of car enthusiasts around the world. When paired with the S50 engine, it transforms into a high-performance machine. To maximize the potential of an S50 swapped E30, several performance upgrades can be implemented. This article explores the best performance upgrades focusing on exhaust systems, ECU tuning, and intake enhancements.

Understanding the S50 Engine

The S50 engine, originally from the BMW M3, is known for its high-revving nature and impressive power output. When swapped into an E30, it provides a significant performance boost over the stock engines. However, to fully unleash its capabilities, additional modifications are necessary.

Exhaust Upgrades

An aftermarket exhaust system is one of the most effective upgrades for the S50 swapped E30. A performance exhaust not only improves sound but also enhances engine efficiency. Here are some key considerations:

  • Headers: Upgrading to performance headers can improve exhaust flow, reducing back pressure and increasing horsepower.
  • Cat-back Systems: A cat-back exhaust system replaces the stock exhaust from the catalytic converter back, providing a significant increase in flow and sound.
  • High-Performance Catalytic Converters: These converters reduce restrictions while maintaining emissions compliance, allowing for better exhaust flow.
  • Resonators and Mufflers: Choosing the right resonators and mufflers can tailor the exhaust note to your preference while optimizing performance.

Several brands offer high-quality exhaust systems specifically designed for the S50 swapped E30. Some popular options include:

  • Supersprint Exhaust Systems
  • Remus Sport Exhaust
  • MagnaFlow Performance Exhaust
  • Borla Exhaust Systems

ECU Tuning

ECU tuning is essential for optimizing the performance of the S50 engine. It allows for adjustments to fuel maps, ignition timing, and other parameters to enhance power and efficiency. Here are some tuning options:

  • Standalone ECU: Upgrading to a standalone ECU provides complete control over engine parameters, allowing for custom tuning.
  • Chip Tuning: Replacing the stock chip with a performance chip can enhance engine performance without the need for extensive modifications.
  • ECU Remapping: Professional remapping services can optimize the existing ECU settings for better performance based on specific modifications.

When considering ECU tuning, several reputable companies offer solutions for the S50 engine:

  • BMW Performance Software
  • Dinan Engineering
  • Active Autowerke
  • ECU Masters

Intake Upgrades

An efficient intake system is crucial for maximizing the airflow into the S50 engine. Upgrading the intake can lead to improved throttle response and increased horsepower. Consider the following options:

  • Cold Air Intakes: These systems draw cooler air from outside the engine bay, enhancing performance by improving air density.
  • High-Performance Air Filters: Upgrading to a high-flow air filter allows for better airflow while providing superior filtration.
  • Intake Manifold Upgrades: A performance intake manifold can improve airflow to the engine, allowing for better power delivery.

For those looking to upgrade their intake systems, the following brands offer high-quality options for the S50 swapped E30:

  • K&N Performance Air Intake Systems
  • AEM Cold Air Intakes
  • VRSF Intake Manifold
  • BimmerWorld Performance Intake

Combining Upgrades for Maximum Performance

While each of these upgrades can enhance performance individually, combining them can yield even greater results. A well-rounded approach that includes an upgraded exhaust, ECU tuning, and improved intake can significantly boost the overall performance of your S50 swapped E30.

Conclusion

Upgrading an S50 swapped E30 with performance exhaust systems, ECU tuning, and intake enhancements can transform it into a formidable driving machine. By carefully selecting the right components and tuning options, enthusiasts can unlock the full potential of this iconic BMW platform.
