No there different, the GTS Turbo uses 'Nissan' 4 pot calipers with 280mm discs 28mm thick. The GTS non turbo uses single piston 'Nissan' calipers with 280mm discs 25mm thick. The R33 GTR uses 4 pot Brembo calipers with 330mm discs 30? / 35?mm wide.
The GTR calipers will bolt directley on providing you get the GTR discs aswell. Oh and you have at least 17inch wheels aswell.
