52 Idle Jets
130 Main Jets
170 Air Correctors
550 Ex. Pump Jets
50 Accel Pump Jets

Parts for the Weber IDF carburetors are directly interchangeable with the EMPI HPMX carbs. We offer a full line of replacement idle jets, main jets, air jets, venturis, etc. so you can tune the carburetors as needed to suit your engine, click here.

What Version Carb Kit do I need?

EMPI offers three different versions of what is essentially the same dual carburetor kit. The difference in the kits are the intake manifolds and air cleaner assemblies.

47-7317 - Standard Intake Manifolds - Chrome Air Cleaner Caps - Can only be used with Aftermarket 36 Horse Style Fan Shrouds.

47-8317 - Offset Intake Manifolds - Chrome Air Cleaner Caps - Can be used with all Type 1 fan shrouds (slight clearancing may be needed).

47-9317 - Offset Intake Manifolds - Billet Air Cleaner Caps - Can be used with all Type 1 fan shrouds (slight clearancing may be needed).

What size carburetors do I need?

In general we use 40mm carburetors for engines up to 2000ccs. 44mm carbs are used for 2000cc and larger engines. Cams, heads, valve sizes and other factors will determine which carburetor set up works best. At the end of the day though, when in doubt, go larger as venturis and jets can all be changed to make a larger carb suit a smaller engine as needed.

Why choose an EMPI HPMX carburetor over a Weber IDF?

Don't get us wrong, we're suckers for performance and when it comes to VW engines and performance carburetors, few will argue with the quality and performance that comes with the Weber name. That being said, there are better Weber versions than others with the Italian versions being the more preferred. So when EMPI decided to take on the task of reproducing one of the most popular VW performance carburetors they went to the best and made it better. They started with a 44 IDF carburetor as a base for the casting for both the 40HMPX and the 44HPMX carburetors. Some of the first improvements was updated circuitry and profiled throttle shafts to flow better right out of the box compared to the Weber. Now on their 4th generation, having made improvements along the way the HMPX carbs now feature a cast in enrichment plate block off, a vacuum port and extended idle jet tubes to help eliminate clogged idle jets. So, why choose an HPMX Carburetor? Because it works just as well, if not better than a IDF carburetor, it's less expensive, and all the components, jets, gaskets and parts are all interchangeable with the IDF. Why pay more for less?!
