I had this same problem this summer in deciding what pistons to buy. Here's what I came up with:
Arias: A fine piston with a high compression ration off the shelf. You can get some 9:1 compression ones through Twins Turbo, if you want to. The price is right, but I have heard of major shops airing them out.
Weisco: Another fine piston that domestic racers swear by. A friend of mine said he snapped a rod and the piston ended up lodged in the crank. No damage to the piston. But I've not heard of anyone personally running these in our applications.
Cosworth. Thermal coated and probably one of the best out there. But prepare to take out a loan for them.
J&E: Some have reported snapping J&E pistons at the BPU level, so I'm not sure about them at the extreme HP levels that a built engine will be attaining.
J&E PHR Spec: Proven, slightly more expensive, but again proven. Thicker, reinforced crown with a stouter ring configuration. Ideal for nitrous applications I'd say. I went with these myself.
Stockers: Stout, stout, stout. A little heavier than the forged options out there from what I understand, but with the major race team choosing to run them vice all of the options out there, it's a good choice to keep them. I'm not sure I'd run a shot of the Devil juice when running big HP, but for an all turbo application, I'd have no doubts they'd hold up.
Good luck man, and have fun with the rebuild. What rods are you going with?
