Default pistons

what pistons would you guys recommend for a 2000 ej25? I'm shooting for 9:1 compression. Also is there a certain dish design that works well. I'm going to be using WRX heads most likely, so the valve reliefs are probably different.

thanks guys.

Call up Quirte at Crawford Performance (CP), he is a great guy and he gave me a lot of info when ordering mine. Thats where I'm getting my pistons...just waiting on them to get here but i guess all good things come with time

Kyle, just to clarify, are you buying CP pistons from Quirt because people often confuse Crawford Performance and CP pistons.

My 9:1 CR forged Arias Pistons seem to be working pretty damn well.

What boost R U running w/ the 9:1 setup? Is it more powerfull than the 10:1 set up? I wanna get an STI shortblock and boost controller in the future and I was curious if it would be more powerfull than my 10:1 on 4 psi setup.

And to top it off, Quirt designed the pistons for CP... He tries to buy all the Subaru specific CP pistons to resell them, from what I hear (heck, he designed them he should make some money off them...)
