Do u know if this are for turbo set ups?

[s13drifter88]

dome will generally yeild higher compression ratios. those pistons being dish topped probably maintain the stock compression ratio which will be turbo friendly

In regards to this Arias Pistons any one here use them on there KA-T???
Can they be used to boost in the 18-20psi if u have the rest of the proper components??

I ran them with eagle rods in my SR20 to 28psi on a GT30r and I will be using them in my KA-T. I've seen them make over 700whp in two KA-t's at over 40psi.
