It has nothing to do with ESS and everything to do with the Alusil block. The Mahle pistons I'm talking about (and used by Dinan, ESS, and RD-Sport) are manufactured to be compatible with the Alusil block. Not sure if these are...but highly doubt it.For a race car that is rebuilt after every few races, these pistons might not matter. But for a street-car stroker...it probably does.
