As far as 993 is concerned, Italeri (and its rebox) is the only option. It's not really a bad kit, but you'll want a new wheels & tires, because the kit parts look like 15 inch and 55 profile. Fujimi's 18" Ruf or BBS wheel would look good, and are popular on real cars. You may want to use Tamiya's 996 wheels, but that's probably more suitable for the Carrera than Turbo.
