i was reading through Modified mag and saw this:

leave it to MAHLE to create a true drop-in, forged race ready piston for the honda h22 engine block. you know the problem. reinforced matrix cylinder bores always required sleeving the block first. well welcome to easy street. MAHLE's propriety skirt coating (notice the gold skirt) allows the piston to work perfectly without sleeving the block. developed as a piston assembly kit, each goldseries powerpak comes with 22mm wrist pins and round wire locks.


jsut wanted to hear what you guys had to say about this. If these really do work i may build my bottom end with my head.

If I remember correctly the they have a 12.3-1 CR. Thats a lot of compression. And they were like $1700.
Yeah, the JUN pistons bump compression up to just around 12.3:1, give or take a tenth. And they may cost more than other pistons, but they save you almost $1k in sleeving labor. Combine those pistons with a slightly thicker head gasket, and you've got a very streetable compression ratio in the high 11's :number1
