Yes! Excellence is worth every dollar and more. They will try to cover something for every Porsche fan in every issue. I keep all of mine and when I get a new Porsche to me I am always glad I did.

heres my idea of trying to go about something like this:
-968 block (very strong block architecture and oil squirters) dry sleeved at 104mm
-lightened and balanced to the max 2.5L crank
-custom forged titanium short-stroke rods
-custom 12.5:1 4v 104mm pistons
-S2 head with custom cams and solid lifters and a better tensioner, oversized valves and ports and stiffer springs
-dry-sump oiling with external oil cooler
-manual steering, no ac, no balance shafts, and a large alternator
-some kind of custom variable-length intake manifold (long runners for torque, short runners/huge plenum for high rpm hp) along with an open 3" exhaust
and a computer and fueling system to match
trouble is even at 100% volumetric efficiency this 2.7 engine would need to spin at least 9500RPM to get the amount of airflow for 300HP.

Also with enough $$ you could have more than 100% VE
Don't forget that the amount of air needed to reach a certain HP lowers as you increse compression and therefore increase the engines efficiency.
