where to get oversized 1100 cc crossflow pistons?

as per title, 1300 and 1600 are readlily available but anyone come across tjose for 1100 cc engine?

(looking at possible putting 1300 engine back in with higher CR pistons).

In case anyone else knows of some, are you looking for proper oversized (larger diameter) for a bored-out block, higher compression (raised crown), or both?

I wouldn't be happy to guess, after finding out mine were larger than std. I'd probably take piston & block to somewhere like this or this to get them measured. I'm chicken, but it saves getting it expensively wrong!

Think you will find that the 1100 pistons will not fit with 1300 crank and rods as the gudgeon pin height is different. The bores are the same size as both engines use the same block but the stroke is different. Decking the block would raise the compression but the tops of the pistons would need machining which may weaken them?

hmmm ^^^^ good point ... but the 1100 con rods are longer.

difference in stroke is 10.3 mm; so question is what is length of 1100 conrod? 2733E?
