Is it true that you have to sleeve a H22 block to put aftermarket pistons?

[lilgreentank]

hey b20 i wanted to know if its ture that you have to sleeve a h22 block just to put aftermarket piston ....I'm in the mix or going h2b but wanted more compression and i heard that you have to sleeve it if you going to put piston in.............can someone give me more info on that

[bustr]

okay ...from what i know there are aftermarket pistons that you can put in an H that wont destroy the block. i think mahle pistons are ones that ive read about that have been used. sleeving of course will is sure bet though. i went a sleeved block and have never had issues w/ the wall or pistons for that matter.
possible/cheaper alternative could also be getting type s pistons... which i think, not sure are 11.5:1 compression... not 100% on that but i know w/ some milling of the head you can definitely hit your goal w/ that setup alone.

if you run forged pistons you have to sleeve the block. If not then your good but I would suggest you sleeve the block anyway.

wow a fellow TO member lol yeah anyways u have to sleeve if u wanna go after market except for mahle pistons they're made for the stock jdm blocks but if u don't want to get to crazy the type s pistons are great and have to be many many times over on honda tech there are many dyno of 210 plus with those pistons just look it up if I can be of any help let me know on T.O

Mahle Gold Series Are So Far The Best For None Sleeved Closed Deck H22 Blocks..

SLeeve it your stock sleeves are Fiber Reinforced Sleeves. you pistons will go through that like hot knife through butter. you need the iron ductile.

From what I've heard you have to resleeve with your block to run forged pistons. But either way I would sleeve it so in the future you got options and room to go up in power without tearing it apart completely. Do everything right the first time, save yourself the headaches. Right Bustr? lol
