Agreed.  My comments on the 5v-4cyl assumed it to be a normally aspirated
motor.  I am VERY aware of the '91 200 Q and its flat torque curve ;-) 
Generally, smaller turbo sizes promote reduced lag, and this effect can be
applied to older, 10v turbos as well.  However, the 10v motors still don't
have the high-compression ratios of the 20v.  I find it really interesting
that V*lv* now has a 5 cyl 20v turbo of about 2.2L (?) displacement with
about 220+ hp.  Of course it took them a few years longer to bring it out!
