The BMW 2002 is a classic car that has captivated enthusiasts for decades. One of the most popular modifications among BMW 2002 owners is the triple carburetor conversion. This upgrade not only enhances the car’s performance but also adds a distinctive sound and character. In this article, we will break down the costs associated with installing a triple carb conversion on a BMW 2002, aiming for a gain of approximately 20 horsepower.
Understanding the Triple Carb Conversion
A triple carb conversion involves replacing the stock single carburetor with three individual carburetors. This setup allows for better airflow and fuel delivery to the engine, resulting in improved performance. The most common carburetors used for this conversion are the Weber DCOE series, known for their reliability and tunability.
Cost Breakdown
The total cost of a triple carb conversion can vary widely based on several factors, including the choice of carburetors, additional components, labor costs, and whether you choose to do the installation yourself or hire a professional. Below is a detailed breakdown of the expected costs.
1. Carburetors
The primary expense in a triple carb conversion is the carburetors themselves. Depending on the brand and model, the cost can range significantly.
- Weber DCOE 40: $300 – $400 each
- Weber DCOE 45: $350 – $450 each
- Other brands: $250 – $350 each
For a set of three carburetors, you can expect to pay between $900 and $1,350, depending on your choice.

- Fuel lines: $50 – $100
Budget around $150 to $300 for these upgrades.
4. Air Filters and Velocity Stacks
To maximize performance, installing quality air filters and velocity stacks is recommended. These components help improve airflow to the carburetors.
- Air filters: $50 – $100 each
- Velocity stacks: $100 – $200 each
For three carburetors, expect to spend approximately $450 to $900.
5. Installation Costs
