H22a replacing pistons question
 

I cracked the ring lands on my stock h22 with boost. i bought JE 9:1 pistons... im told AFTER i bought them that i HAVE to sleve it or else it wont last but 1000 miles. why is this? or are they wrong?

Re:H22a replacing pistons question
 

Your stock sleeves are homo and made out of Smagma which won't bond to the piston correctly. You heard right. :-\

damn..... so IF i can return the pistons i bought what kind should i get because i dont have the kind of cash it takes to sleve the block.

I'm no H series expert so my advice isn't worth ----, but I would suggest the factory OEM parts if you're not going to sleeve it. :-\
