The PMO 40mm Street Carburetor Kit is the smart choice for moderate-displacement 911 engines (2.8-3.0L) — the original 2.7L motors, early SCs, and rebuilt 3.0L Carreras. Modern Anaheim, California manufacturing eliminates every weakness of the decades-old Weber IDA conversion that came before. Now made under EMPI ownership with the original Richard Parr engineering.

Kit Includes

• Two PMO 40mm carburetors with 36mm chokes
• 145 main jets, 190 air correction jets, 55 idle jets
• F11t emulsion tubes, 0.5 float check valve
• PMO throttle linkage
• PMO fuel pressure regulator
• Carburetor isolators
• Complete hardware and fuel hose

Why PMO Over Weber IDA

• One-piece stainless steel throttle shafts with ball-bearing support — no shaft wear or binding
• Full throttle body opening for significantly improved airflow vs equivalent-size Weber
• Float bowl sight glasses for tool-free fuel level tuning
• Redesigned fuel inlet for higher, more balanced flow
• IDF-derived modern jet and float technology
• Heat-soak resistant construction

Fitment

• 1965-1989 Porsche 911 with 2.8-3.0L engine
• 911 SC 1978-1983 (3.0L)
• 914-6 (with appropriate manifolds)
• Compatible with stock manifolds OR PMO billet manifolds (sold separately)
• Street jetting — smooth, predictable, daily-driver friendly

Made in Anaheim, California

Manufactured by EMPI at PMO's California facility using updated CNC machinery and the original engineering. Aerospace-quality castings and precision machining. American-made.

Note: Intake manifolds NOT included. Use OE manifolds or upgrade to PMO CNC billet manifolds.

Installation: Final jetting may need adjustment for your specific engine. PMO Carb Setup Sheet recommended before install.
