Here is a comparison of the old JE vs the new JE FSR piston. These are 100mm.

The piston on the left looks very much like the forged piston I was referring to with the "97" marking on the crown a little earlier in this post. Its is still a forged blank-not cast so I am hoping it is one of the modified designs and I am not going to have a short lived engine. Its not as nice as the one on the right (FSR) though...thats the top of the line they offer.
FWIW, I don't have a racing 3.4 (98mm) turbo but do drive 50% DE and track days.
JE is supposed to be top notch and recommended by alot of top engine suppliers in Pano and Excellence. This talk of exploding pistons is pretty disturbing.
