i have not got a clue who done the engine rebuild it has a tag on it saying mex engines but i never heard of them

A quick google shows nothing either. What stamps in the book do you have for 20k ago? No invoice?

It could be a shoddy rebuild, so I'd be certain everything else is ok before putting it back together.

my car is a my99 uk spec i got the sti engine from someone else bit of a project so i have no service history on that engine only what the seller told me but by the look of the engine very clean ie hardy no carbon on pistons so rebuild would check out with miles

They will be .50 oversize giving a bore size of 92.50mm - if they are stamped HB with two dots facing the front,cross hatching underside of the crown - they are standard cast Subaru pistons.
The forged ones have a smooth underside of the crown and be stamped HF 2/3/4
A few pics would help if possible.
