Dual 34 Epc Carburetor Kit, Type 2 & 4 VW 914, Dual Port

OVERVIEW

Unlock the latent power of your Type 4 or Porsche 914 engine with the EMPI Dual 34 EPC Carburetor Kit. This kit is specifically engineered for enthusiasts who want to bridge the gap between a restrictive stock single-carburetor setup and the aggressive, fuel-hungry nature of larger 40mm or 44mm dual carbs. The EPC 34 series is legendary in the air-cooled community for providing a significant boost in mid-range torque and throttle response without the common "gas-guzzler" reputation associated with larger performance units. By utilizing two independent carburetors, your engine benefits from a more direct intake path, ensuring that each cylinder head receives a balanced and consistent fuel-air mixture. Whether you are navigating daily traffic or cruising the open highway, this kit delivers a smoother idle and more predictable power delivery across the entire RPM range.

Installation is designed to be as straightforward as possible, making it an ideal choice for the "weekend warrior" mechanic. This comprehensive kit includes everything you need to complete the conversion, including aluminum intake manifolds, a high-quality hex-bar linkage system, and chrome air cleaners with gauze elements. The EMPI EPC 34 carburetors come pre-fitted with baseline jetting that works exceptionally well for stock to mildly modified 1700cc, 1800cc, and 2000cc engines. By upgrading to this dual-port system, you are not just improving performance; you are enhancing the overall drivability and reliability of your vintage Volkswagen or Porsche. Don''t let a tired, 50-year-old single carburetor hold your engine backgive it the breath of life it deserves with this precision-engineered dual kit.

PRO TIPS

1. Manage Your Fuel Pressure

One of the most common mistakes when installing EMPI EPC 34 or similar Weber-style carburetors is over-pressurizing the needle and seat. These carburetors are designed to operate optimally between 1.5 and 2.5 PSI. Most stock fuel pumps, and certainly most electric pumps, will push well over 4 PSI, which can lead to flooding, erratic idling, and fuel leaking from the top of the carb. We highly recommend installing a high-quality fuel pressure regulator between the pump and the "T" fitting to ensure you don''t overwhelm the floats. This single step will save you hours of tuning frustration.

2. Use a Sync Tool for Perfection

While you can get the engine running by "ear," you will never achieve a perfect idle or crisp off-idle transition without a synchronization tool, often called a "Snail" or Uni-Syn gauge. Since dual carburetors operate on independent linkages, it is vital that both carburetors are drawing the exact same volume of air at idle. When adjusting your hex bar, ensure there is no tension on the arms at idle; the linkage should "click" into place only after the idle speed screws are set. If one carb is pulling more air than the other, the engine will fight itself, leading to increased vibration and heat.

3. Check for Vacuum Leaks at the Base

Type 4 engines are notorious for being sensitive to vacuum leaks at the intake manifold base. Before you bolt everything down, ensure the mounting surfaces on the cylinder heads are perfectly clean and flat. We recommend a light smear of high-temperature sealant on the gaskets to ensure a 100% airtight seal. Additionally, after your first few heat cycles, go back and re-torque the manifold nuts. The expansion and contraction of the aluminum can cause things to loosen slightly, and a tiny vacuum leak can make it impossible to get your idle mixture screws adjusted correctly.
