Why does the h23 block need to be sleeved?

[preludeh23]

why does the h23 need to be sleeved in order to put in forged pistons. i just bought a 92 prelude and plan on boosting in, and i have read everywhere that you must sleeve the block first. why is this??

You don't HAVE to, but there are very few machine shops that can properly hone a FRM sleeve. The easy way out (and expensive) is to remove the FRM sleeve and replace it with an iron one that machine shops know how to work with.

In your opinion, if my goal is to end up at about 300 hp, do you think i should resleeve the block?

No.
