EMPI Piston & Cylinder Set — 94mm × 82mm, 2276cc Stroker | VW Type 1 Air-Cooled (98-1957-B)

EMPI's 94mm × 82mm piston and cylinder set (98-1957-B) is the heart of the most popular air-cooled stroker there is. Run on an 82mm stroker crank, this matched four-cylinder kit builds a 2276cc Type 1 — pistons, cylinders, rings, pins and clips in one matched set.

Vehicle Fitment

  • VW Type 1 Air-Cooled: Beetle, Super Beetle, Bus (Type 2), Karmann Ghia — cases machined for 94mm × 82mm

This is a build component, not a bolt-in. A 94mm bore requires the case cylinder spigots and the heads to be machined to accept 94mm barrels, and the 82mm stroke requires case clearancing. Not confirmed: stock un-machined cases, Type 4 engines.

Key Features & Benefits

  • 2276cc stroker: 94mm bore × 82mm stroke — the go-to air-cooled stroker displacement
  • Matched set of 4: pistons and cylinders sized together
  • Complete top-end: includes rings, wrist pins and clips
  • Built to pair: designed for the EMPI 82mm counterweighted crank (00-8182-0)
