Re: h23 pistons and rods?springs?
 

are those pistons forged? If they are, you're gona need to sleeve your block.

The only pistons for h23 that you dont need sleeving for are the mahle gold series.

i thought it was recomended to sleeve the block? what would happen if i didnt?

Re: h23 pistons and rods?springs?
 

you cant run forged pistons without resleeving h blocks.

h motors are really strong cause of the closed decks they have. I am going to sleeve my h22 though cause I'm shooting for higher than 500 hp.
