I think the 2002turbo body shell is as all other big bumper/square
tail light generation - which is to say reinforcements in the trunk and under floor to support higher impact / crumple at front and rear impacts -
2002, 2002tii, 2002turbo all the same shell.
(Matt's link is not working)
this is from 2002turbo.nl site
note the reinforcements under the trunk floor which saddle the diff area
they are not present on round tail light bodies - pre-big-crashing-bumper
shells - as pictured below
