EMPI Magnesium Engine Case — 94mm Bore, Full-Flow Drilled (98-0440-B)

The case is the foundation every air-cooled build sits on. This is EMPI's AS41 magnesium alloy engine case (98-0440-B) — an all-new casting machined for 94mm cylinders and drilled and tapped for full-flow oiling, ready for 1914–2276cc big-bore and stroker builds.

Vehicle Fitment

• VW Beetle: 1954–1977
• VW Super Beetle: 1971–1979 — the Super Beetle did not exist before 1971
• VW Karmann Ghia: 1956–1974
• VW Type 3 (Squareback, Fastback, Notchback): 1961–1973 — the Type 3 runs the same Type 1 case with its own pancake cooling tin and oil-cooler layout
• VW Bus / Transporter (Type 2): 1955–1971 only — the 1972-and-later US Bus is a Type 4 vehicle and uses a completely different case
• VW Thing (Type 181): 1973–1974 — the only two model years the Thing was sold in the US

Confirmed: VW Type 1 94mm builds — 1914cc (94 × 69) through 2276cc (94 × 82) strokers. Not confirmed: stock 85.5mm or 90.5/92mm builds, or any Type 4 engine.
