LOL!
Stock for stock the R34 GTR V-Spec II Nur will ass rape the R33 GTS-T.
If you dump $30K into the GTS-T VS stock Nur, you will beat it for sure...
If someone dumped $30K on a Nur VS stock GTS-T, the Nur will win.
All depends on how big your wallet is.
Why don't you just buy a R32 or R33 GTR if you are going to spend $40K all up?
