I just swapped a jdm closed deck h22a in my accord, its gonna be boosted but it will be built before i go turbo. For you guys out there running boost since its closed deck should i change the sleeves to darton iron sleeves of just leave them alone. someone told me the forged internals will rub on the aluminum sleeves and scrape them up, so who better to ask then people running boost on their h22a. How much boost are you guys running and what if any internal work do u have. I appreciate the help.

There's my thread on a related topic.

I get the feeling that even those "compatible" pistons won't be ideal. I think the only real way to get higher boost levels is to resleeve...do it right. I'm probably going this route if 7-8psi doesn't appease me.
