If I have an engine with cylinder bores of 86mm and I decide I want to fit forged pistons surely I should have the block bored to 86.25mm and have 86.25mm forged pistons. Why would someone want to fit 86.00mm forged pistons to a block that’s already been in use?
Keeps the weight down on the pistons for a start. When engine is stripped down for Rebuild can increment up in bore size. Saves having to buy another block.
Just speaking of what the factory specs are for the engine. I haven’t bought pistons yet because they are £1000 it’s for a 6 cylinder. But Iv oticed this before for other engines they offer forged pistons for original bore size.
