Legality issues aside for now, the V8 may not have the advantage over the
20V since although boost control changes are not allowed, anything else
in the intake is allowed, so quite a bit more power can be gotten out of
the 20V by improving flow with stock boost levels. There is also that
short overboost.... You may be able to build some kind of box that fools
the computer into thinking that you are constantly in a state of having
just opened the throttle, so that it maintains that overboost indefinitely.
Gray area to be sure, but possible.

A part from an 80/90 model will not be legal if Eric/My opinion holds true.

Must have stock rotors, but any pads are allowed. SS brake lines are
allowed too. Springs, shocks, strut mounts, sway bars, bushing material are
free. Bushing _type_ is not free. If you have bushings, you must use
bushings - you can't change to heims where there are bushings. There is
an additional loophole, though. Any type of lateral suspension location
is allowed on the rear, and hence, any type of joint (including heims) is
allowed on that lateral locator.
