PMO 46mm Carburetor Kit | Porsche 911 3.2–3.4L Street | Billet Triple-Barrel IDA-Style Pair (PM-O805-0)

PMO 46mm Carburetor Kit — Street, Billet Triple-Barrel Pair for Porsche 911 3.2–3.4L (PM-O805-0)

The billet induction the air-cooled 911 crowd actually trusts. The PMO 46mm Carburetor Kit (PM-O805-0) is a matched pair of aerospace-grade billet carburetors — three barrels per carb, one throat per cylinder — jetted for a 3.2–3.4L flat-six in a street tune. Think of it as Weber 2.0: the proven IDA-style architecture, rebuilt in solid billet with far fewer plugs, gaskets, and leak points, so idle is steadier, throttle response is instant, and tuning stays put.

Vehicle Fitment

• Porsche 911 Carrera: Air-cooled flat-six engines of 3.2–3.4L displacement (typical of 1984–1989 cars, and any engine built to that spec).
• Note: Fitment is driven by your engine's displacement, cam, and compression — not just model year. Match the kit to your actual build.

Why Choose PMO?

Billet, not cast: machined from solid aluminum with a superior throttle-shaft and fuel-circuit design, engineering out the leaks and flat spots that plague old Weber IDAs and Solexes. It's also simpler than CIS or MFI — a clean, mechanical carb setup that ends CIS fuel-distributor headaches and hard-to-service mechanical injection, while keeping that period-correct velocity-stack look.

Key Features & Benefits

• Billet, not cast: Machined from solid aluminum with a superior throttle-shaft and fuel-circuit design.
• Simpler than CIS or MFI: Ends fuel-distributor headaches and hard-to-service mechanical injection.
• Matched to your motor: 46mm throttle bore with venturi and jetting sized for a 3.2–3.4L engine in street spec — not a generic off-the-shelf carb.
• Smooth where it counts: Crisp part-throttle, even fueling across all six cylinders, and a tune that holds.

Frequently Asked Questions

• Are these made to order? Yes. Every PMO set is built and jetted to a PMO Carb Setup Sheet based on your displacement, cam, compression, and even elevation, so it runs right out of the box. This is a build-to-order item, not off-the-shelf.
• What do PMO carbs replace? They're the go-to conversion when replacing tired Weber or Solex carburetors, or deleting CIS (K-Jetronic) or MFI mechanical injection.
• How do I know this kit fits my engine? Fitment is driven by your engine's displacement, cam, and compression — not just model year. This kit is jetted for a 3.2–3.4L flat-six in street spec; match it to your actual build.
