Good info Ralph. However, here's an alternative thought. Mahle makes standard pistons and cylinders in standard sizes (no custom stuff, unless you buy 20-30 sets or so). The JE's are highly used in custom jobs on race engines, where failures may or may not be attributed to the pistons themselves.

I have a tendency to think that JEs get a bad rap from people who use them in overstressed race or street engines (too much boost?). A piston in this situation is going to fail, whether it's a JE or a Mahle one. I've had many customer run JEs in their street engines with good success. These customers weren't pushing the limits of the engine, but simply going with a JE piston in order to give a mild increase in compression and to save some $$$ on the replacement costs.

Just a thought...
