86mm is standard ,as for the max size im not sure but i do know they do 88mm pistons.

Its just i saw Pikeys addy and it says 87mm and seems that is 1mm oversize i wondered if that was the max as it is on cosworths,

As per pm, 88mm is the max you can go

I think i saw a thread on here previously which had a diagram showing a cross-section of the N1 and GT blocks.

There is a fair bit more meat in between cylinders on these blocks and i could be mistaken, but can't you get 1mm more bore size out on the GT block?
