EMPI HD Bubble-Top Engine Case — 94mm Bore, Full-Flow Drilled | VW Type 1 Air-Cooled (98-0454-B)

If you're building a 94mm big-bore or stroker motor, you can't run it in a stock case — the cylinder spigots have to be cut for the larger barrels. EMPI's HD bubble-top aluminum case (98-0454-B) is all-new, machined for 94mm cylinders and already drilled and tapped for full-flow oiling. It's the proper foundation for a 1914cc, 2110cc, or 2276cc build.

Features

• All-new heavy-duty aluminum casting — stronger and more heat-stable than magnesium for high-output builds
• Bubble-top design adds material in the high-stress upper case area
• Machined for 94mm cylinder spigots — ready for big-bore and stroker barrels
• Drilled and tapped for full-flow oil — no extra machine work to plumb an external filter/cooler
• 8mm case-stud threads
