As of this year the differences between the two (for Evos / STi's anyway) were not that major.

Targa West 2010 allowed the use of 3" Exhausts which was long overdue.

The main thing now that you can do is run E85 and bigger wheels / tyres. I am not 100% certain but I dont think you could run a heated front screen under the old Targa West rules.

One stupid thing that I have picked up with my evo is that you can get fully homologated plastic windows. Targa Tas specifically says all windows must be glass whereas because they were properly homologated you could of run them at Targa West.
