I have two sets of Mahle 2.4 biral cylinders that are worn out of spec. They can be machined to the smallest oversize (0.25 mm), but is it possible/recommended to use JE pistons?
As I understand, JE are primarily designed for use with alu/nicasil cylinders. The only information LN Engineering provide regarding the topic is this:

- Piston clearances designed for aluminum cylinders, steel/iron cylinders may require additional clearance.

For some reason Mahle seem to only provide sets with both cylinders and pistons. Strange.
