Probe is where I am getting my stuff. MikeH also got his setup from them. Great prices and good quality. I sent Mike (at Probe) a stock piston and rod a while back so they have something to go on. Tell him you know Charlie. The only thing to remember...they custom make their pistons from 2518-t6 aluminum....no silicone content. This is of course stronger, but *may* "clatter" untill it warms up. For me, it was a good trade off, I want reliability at higher boost. Good luck
