Frequently asked questions

What is this 2.25L petrol piston and what size is it?

This is a replacement piston for the Land Rover 2.25 litre four-cylinder petrol engine, supplied at +0.020 inch oversize. The oversize piston suits a cylinder bore that's been machined out during an engine rebuild to clean up wear or damage in the bore.

Which 2.25 petrol engines does this piston fit?

This piston suits the three-bearing engines (prefix 901 and 904), all Suffix-A five-bearing engines (prefix 361), and the 8:1 compression five-bearing engines from suffix B onwards. It does not fit the 7:1 low-compression five-bearing engine (prefix 364), which takes a different piston.

What does +0.020 inch oversize mean when ordering pistons?

+0.020 inch oversize means the piston is 0.020 inch larger than standard, made to run in a cylinder that's been rebored to match. Check the oversize your engine has been machined to before ordering, and replace pistons as a matched set across all four cylinders.

Which Land Rovers use the 2.25 petrol piston?

The 2.25 litre petrol engine was fitted to the Land Rover Series 2 and 3 and early Defender models. Confirm your engine's bearing type, prefix and compression ratio rather than just the vehicle, as that determines which piston is correct.
