Ok guys I would like to know what other ej20 series piston's that are forged that can fit my ej20g. I had 2 of my pistons break at the piston ring area and I want something stronger and better for replacement. I'm going to replace all 4 pistons not just the 2 broken ones. We have a version 6 sti pistons available, also a version 4 wrx ra pistons also I think ej20k I'm not sure. The difference is that my stock pistons are taller then the other two, but same 92mm size. Will one of these be an ok replacement or should I find some after market racing pistons? I've really had some badluck with my ej20g cause its my second motor because the previous one melted the pistons after shattering some piston rings. It seems like a weak point of the ej20g I've encountered is the stock pistons. So yes I'm still a noob at the subaru thing so everyone's opinions and info's will help greatly.
