Piston Set 87.0mm SOHC - Forged 10.0 - 11:1 w/Rings (Fiat Bertone X1/9, 128, Yugo) - NEW

Specifically designed for Midwest-Bayless! - SPECIAL ORDER ONLY.

This is a set of four American made, lightweight forged aluminum pistons, suitable for all Fiat or Yugo SOHC racing or hot-street application (1300 or 1500).

We use these exact pistons in our Midwest-Bayless Fiat X19 race cars.

This particular style has a slightly taller compression height than stock, and a small, flat dome which produces 10:1 compression with a stock North American head, and over 11:1 with a milled flat North American, or Euro-style head.

11:1 compression is the exact target for SCCA Limited Prep production racing.

Specifications:
- Diameter: 87.0mm
- Valve Pockets: 39mm
- Compression Height: 35.2mm
- Dome Height: 2.4mm
- Recommended Skirt Clearance: .076mm (.003 in)

These pistons use three rings. Piston rings, slip-fit pins and retainer circlips included.

NOTE: These are SPECIAL ORDER items that have up to 4 weeks of production time.  No refunds or returns.

Other bore sizes are available, however 87.0mm is the optimal oversize bore for all Fiat 1300 and 1500cc motors. If you require alternate bore size, please call before ordering.
