Do you happen to know if it's still an expensive swap to go from the TT A/T to the getreg 6sp? I know it's a pricey deal starting with an N/A 5spd or A/T and going to the 6sp + rear-end

I've been wondering if the TT A/T is less of a hassle since it might have the stronger rear-end (driveshaft, rear diff, etc)? I'm still new to the whole Supra dealio, but i'm trying to learn before i jump into it..
