The BMW 335i is a beloved performance car known for its impressive balance of power and handling. One of the ways enthusiasts enhance the performance of their 335i is through the installation of forged internals. This article explores the impact of forged internals on the performance of the BMW 335i, discussing the associated costs and the expected power increase.
Understanding Forged Internals
Forged internals refer to engine components that are manufactured through a process of forging, which involves shaping metal under high pressure. This method produces components that are stronger and more durable than their cast counterparts. Key forged internals for the BMW 335i include:
- Forged pistons
- Forged connecting rods
- Forged crankshafts
Benefits of Forged Internals in the BMW 335i
Upgrading to forged internals can significantly enhance the performance of the BMW 335i. The benefits include:
- Increased Strength: Forged components can withstand higher levels of stress and pressure, making them ideal for high-performance applications.
- Improved Reliability: The durability of forged internals reduces the risk of engine failure during high-performance driving.
- Enhanced Power Potential: Forged internals allow for higher boost levels and more aggressive tuning, resulting in increased horsepower and torque.
Cost Considerations
While the benefits of forged internals are clear, the costs can vary widely based on several factors. Here’s a breakdown of potential expenses:
- Parts Cost: The cost of forged pistons, rods, and crankshafts can range from $1,500 to $4,000 depending on the brand and specifications.
- Labor Costs: Installation can be labor-intensive, with costs ranging from $1,000 to $2,500 depending on the shop and the complexity of the job.
- Tuning Costs: After installation, professional tuning is recommended, adding another $500 to $1,500 to the overall cost.
Expected Power Increase
The power increase from installing forged internals can be substantial, particularly when paired with other performance modifications. Here’s what you can generally expect:
- With Stock Turbo: Expect an increase of 50-100 horsepower over stock, depending on the tuning.
- With Upgraded Turbo: Power gains can exceed 150 horsepower, pushing the limits of the 335i’s performance.
Conclusion
Forged internals are a worthwhile investment for BMW 335i owners looking to enhance their vehicle’s performance. While the initial costs can be significant, the benefits in terms of power, reliability, and overall driving experience make it a compelling option. By understanding the costs and expected power increases, enthusiasts can make informed decisions for their performance upgrades.
