Actually, I heard the turbo cams are in fact an improvement 
for the NA motors.  Don't know why.  Maybe they have increased 
lift which makes up for any shortcomings in overlap?

I also "heard" that too much overlap is bad for CIS motors, 
because it causes "pulses" in the air flow, which make the 
air sensor plate "bounce" and causes problems with fuel 
delivery.

I "hear" alot of different stuff.  I'm curious if anyone's 
got any BTDT's with a turbo cam in an NA I5 too.

It would work out perfect for me!  I would get a turbo 5 
for the 4ksq, put the turbo cam in the Coupe with the 4k 
exhaust manifold, and put my current Schrick in the turbo 
motor.  It would be a most efficient use of my overextended 
finances!  Uh,...back to work now...
