I should clarify a bit - I don't mean to say that a STOCK n/a engine bottom end can handle that power, rather it can be built to. Apologies for the confusion. Anyway, the point is that the engines are identical except for the pistons and rods. I think Danno is running additional fuel (slightly rich mixture) to keep the EGTs in check, but I'll verify that when I next speak with him to satisfy your curiousity.

Anyway, to get this back "on topic", I'll just say that the choice remains to run higher compression with lower boost (better low-end) or lower compression with higher boost (better top-end). The superior forged metallurgy tends to imply the latter as the better choice (I'm personally opting for this method on my own car). With regards to ring blow-by, I would stand by what I said earlier - whichever pistons are chosen (they should be stock to avoid damage to the alusil bore or to the piston BY the alusil bore) using good NEW properly installed stock rings should suffice.
