Austin Healey 100 Piston Set - Standard | BN1-BN2

This complete set of four standard-size pistons is made for the Austin Healey 100 BN1 and BN2 four-cylinder engine. Supplied with piston rings, gudgeon pins and circlips, it provides the piston components required for an engine rebuild where the cylinder bores remain at standard size.

Features

• Set of four standard-size pistons
• Piston rings included
• Gudgeon pins and circlips included
• Made for Austin Healey 100 BN1 and BN2
• One complete piston set required per engine

Benefits

Supplying the pistons, rings, gudgeon pins and circlips together allows the piston assemblies for all four cylinders to be renewed without sourcing these components separately.

The standard-size set is suitable where measurement confirms that the cylinder bores remain at standard size and are suitable for rebuilding without an oversize rebore.

Technical Details

• Engine type: four-cylinder Austin Healey 100
• Original engine capacity: 2,660cc
• Standard cylinder bore: 3.4375in (87.31mm)
• Piston size: standard
• Quantity: four pistons per set

The cylinder bores should be measured before ordering. Final bore condition and piston-to-bore clearance should be checked as part of the engine machining and assembly process.

Vehicle Application

• Austin Healey 100 BN1
• Austin Healey 100 BN2

If the engine has previously been rebored, check the existing bore and piston size before ordering. A separate high-compression piston range is available for 100M and Le Mans-type engine specifications.
