1835cc is the most popular displacement bump for a Type 1, and this is EMPI's thick-wall machine-in version (98-1958-B) — 92mm cylinders with extra wall material for more strength and cooling surface than a standard 92mm slip-in set. The hypereutectic high-silicon-alloy pistons run with minimal expansion for long service life. This is a machine-in set: your case and heads must be cut for 94mm to clear the thicker cylinders.

Features

  • 92mm bore × 69mm stock stroke = 1835cc displacement
  • Thick-wall cast-iron cylinders — stronger and cooler-running than a standard 92mm slip-in
  • Hypereutectic aluminum-alloy pistons, high silicon content for low thermal expansion
  • Complete set of 4: cylinders, pistons, rings, wrist pins, and clips
  • Runs the stock 69mm crank — no stroker crank required

Fitment

CONFIRMED: VW Type 1 air-cooled — Beetle, Super Beetle, Karmann Ghia, Bus (Type 2), Type 3 (Squareback, Fastback, Notchback). Machining required: case machined for 92mm and heads cut for 94mm to clear the thick-wall cylinders. This is a machine-in set, not a slip-in. NOT CONFIRMED: Type 4 / 914 engines (different bore spacing and case).

Wonderful Room Partition !
Color: Black, Size: 88"- 4 Panel
This product is made very well, packaged, and assembled with no problems. All parts and tools are included (except a Phillips screwdriver.) I put this item all together by myself on a bed to make it easy and simple. I made sure that every screw head was attached where the recessed dimples are located on the vertical poles, just don't overtighten anything. Everything fits like a charm, good quality, looks great, perfect height, rolls with ease, proper privacy, really impressive ! I got the 4-panel in black color. I would certainly buy this item again ! Thank you !

Sturdy and Easy to Move
Color: Black, Size: 132"- 6 Panel
This 6 ft black partition on wheels is exactly what I needed to divide space without sacrificing style or stability. It’s sleek, professional-looking, and blends in well with any environment—from office spaces to home studios. The build quality is impressive—very sturdy and doesn’t wobble at all once it’s in place. The wheels glide smoothly and lock securely, making it easy to reposition or keep stationary as needed. Assembly was quick and straightforward, with all parts clearly labeled. Overall, this partition is a perfect combination of functionality and design. Highly recommend it if you need a durable, mobile room divider that looks great and performs even better.

Nice once put together.
Color: Black, Size: 88"- 4 Panel
I really enjoyed these ones. They got put up, putting them together was a two-man task and not very easy at all. They work really good. They're very heavy duty. You can hang things on them. I kick mine out of the way and they work like a charm!
