PMO 50mm Carburetor Kit for Porsche 911 — 3.5–3.8L Street Set-Up | Air-Cooled 911, 964, Stroker (PM-O807-0)

The PMO 50mm Street Carburetor Kit is designed for 3.5-3.8L Porsche flat-six engines and other large-displacement builds. The 50mm bore is PMO's largest "street" application — big enough to feed serious displacement without sacrificing low-RPM driveability. Built in the USA, jetted for street tuning, and supplied complete with manifolds, linkage, and air cleaner.

Why PMO Beats Weber and Solex

• Made in USA — billet aluminum machined in California
• 50mm bore — proper sizing for 3.5L+ displacement
• Street-tuned — drivable on pump gas with mild cam
• Precision throttle shafts — sealed bearings prevent the Weber IDA air leak problem
• Better long-term support — PMO sells dedicated rebuild kits, jets, and venturis

Tuning tip: 50mm carbs are big — they want decent cam timing and compression to make the most of the airflow. If you're running a stock 3.6 with no other mods, you'll likely get better drivability from the 46mm street kit. PMO sells 50mm jet kits (PM-O854-0) for fine-tuning.
