Twin 34 EPC EMPI Carburettor Kit - Type 1 Twin Port Engines

This Twin EMPI 34 EPC carburettor kit is an excellent performance upgrade for all Type 1 twin port 1300cc–1600cc aircooled engines, providing improved throttle response, stronger mid-range performance, and smoother overall running—without sacrificing fuel economy. As a more affordable alternative to a Weber 34 ICT setup, this system delivers impressive drivability gains at a fraction of the cost.

Designed specifically for twin port engines, the kit includes a complete set of high-quality components to ensure durability, smooth operation, and reliable synchronisation. With the combination of high-flow aluminium manifolds, precision-engineered linkage, and free-flowing air cleaners, this setup provides a well-balanced intake system suitable for both daily driving and spirited road use.

Every kit features:

• Aluminium alloy hex-bar linkage with steel ball ends

• Sealed aircraft-grade Heim rod ends

• High-flow aluminium intake manifolds

• Thick, high-strength steel linkage mounts

• Gauze high-flow air cleaner assemblies

• Coil relocation bracket (for improved carb clearance)

• Brass fuel tee

• Detailed illustrated installation instructions

Jetting Specifications (Pre-installed)

• 1.75 needle & seat

• 150 main jet

• 55 idle jet

• 175 air correction jet

• F-6 emulsion tubes

This jetting works perfectly for most 1300cc–1600cc twin port engines. However, on engines over 1776cc, rejetting will be required to achieve correct fuelling. As with all twin carb installations, for the best results these carbs should be balanced and tuned on a rolling road to maximise performance and drivability.

Important Fitment Information:

• NOT compatible with 1200cc engines

• Suitable only for Type 1 twin port configurations

• EMPI Part Number: 47-7411-0

This EMPI 34 EPC setup is a proven and cost-effective upgrade that delivers noticeable gains in power, response, and engine smoothness—perfect for anyone looking to enhance their aircooled VW’s performance while keeping running costs under control.
