I have another theory that the lack of a "bridge" accross the water jackets around the cylinder walls on the block also contributes to this at higher boost levels. Looks at the JZ block pictures sometimes and you will see they added "bridges" across the water jackets..(not many bhg's) This is just my opinion..
