Kit includes:

  • 4 Cylinders
  • 4 Pistons
  • 4 Wrist Pins
  • 8 Wrist Pin Clips
  • Complete Set Piston Rings

Cima/Mahle 85.5mm pistons & cylinders come as a complete set with forged aluminum pistons, cast iron cylinder sleeves, wrist pins, clips and piston rings. The cylinders are made for the stock 69mm crankshaft and will fit 1300cc, 1500cc & 1600cc engines. Installing the 85.5mm pistons and cylinders in a 1300 and 1500 engine will change the displacement to 1600cc. 1300 engines will need 1500 or 1600 heads to fit the larger cylinders. The 85.5mm piston and cylinders sets will fit 1966 through 1977 Standard Beetles, 1971 through 1979 Super Beetles, 1966 through 1974 Karmann Ghias, 1963 through 1971 Type 2 Bus Models, 1962 through 1973 Type 3 models and 1973 to 1974 Things. The outer diameter of the cylinders (sleeves) is roughly 89.5mm at the case & 94mm at the head.

Engine Details for 85.5MM Pistons with 69mm Crank and 1300-1600cc Engine Case:

  • Displacement: 1600cc (actually 1585cc but VW rounded up)
  • Pistons: 85.5mm Forged Aluminum
  • Cylinders: Cast Iron
  • Case Machine Work: None Required
  • Head Machine Work:
    • If You Have a 1500/1600cc Engine: No machine work required
    • If You Have a 1300cc Engine: You will need to machine your heads to fit 1500/1600cc pistons, or purchase new heads

Forged vs. Cast Pistons

Forged pistons are stronger. In a high performance application a forged piston is a necessity. A high revving, high compression engine or a turbocharged engine will benefit from a piston than can withstand higher temperatures and see much more load than a standard, street driven engine. Forged pistons will take longer to warm up than a cast piston. With that longer warm up time, a forged piston will suffer from “piston slap” as it will be looser in the cylinder until it comes up to temp and expands. If the engine is driven hard before it is fully warmed up, the piston is prone to wearing prematurely. Forged pistons do have a place, just make sure it is the right place for your VW engine!

Before you Install:
New piston & cylinder kits ship with the piston rings installed in the pistons, inside the cylinders. However, this does not mean they are ready to install. The pistons should be removed so the rings can be properly clocked, then reinstalled before engine assembly can begin. We cover the procedure in the video below.
