Let's see, I built up an Evo some time ago, this is going from what I can remember.
Additional Evo parts are: graphite chassis and top deck, beefed up front and rear shock towers, ally shocks, lightweight diffs, uJ's in the rear, adjustable turnbuckles, beefier tierod ends, titanium screws throughout, full bearing set, torque splitter, lightweight kingpins, ballraced steering, titanium hinge pins, and off course the obvious things like orange wheels and Evo decals which are getting harder to find by the day.
There maybe a few other things that i've forgotten but thats the main upgrades.
I really like your idea of running it against modern competition - been thinking about that myself.[]
