Absolutely. The 'S' Cam addition alone (without porting and relieving, 
shaving the head, etc.) will yield +6 HP at 4000 rpm, +12 at 5000 rpm, 
+18 at 6000, and +24 at 7000 with NO increase below 4000. With the 
other mods, of course, the yield is much higher with as much as +48 HP 
at 7K (according to friend who's done it) available. But like the 
Honda, its all at the top.

Well, the original poster quoted 250 HP from twin turbos, I merely 
mentioned that one could approach that without resorting to 
twin-turbos, which really shouldn't be used with high-milage engines. 
The specifics I didn't go into and you were right to shine a more 
focused light on the subject.

Yes. That's the advantage of turbos, the power increase comes on at 
much lower RPMs with a much wider torque band.
