I know that there are very few aftermarket pistons that will work with a stock bore
h22a engine, what I am wondering is are there any other options besides re-sleeving the block, for instance can you bore the stock cylinder coating off and run a regular piston, or is there not enough cylinder to do that?

I am trying to build this engine for turbo, and would really like to get away from the stock rods and pistons, but the more research I do it seems like sleeving the block is the only solution. thanks in advance for any replies I do appreciate the help, I'm a bit of a newbie when it comes to the h22

 

there is a huge thread in the FI forum , search for mahle pistons.. they supposedly work well with the frm cylinders found in the h series.

 

thanks

 

theres a place that will sleeve your block for 466 bucks the sleeves will hold 50 lbs of boost.Nice guys my block is there right now.Or go with the mahle slugs only other solution.

 

do you have any contact information for them?
