I belive so. Or I should say I hope so, as Im putting a GTR one in the car tomorrow... (car being rb20 powered).

Umm, I didnt word that properly. They should both bolt up, I dont think they are actually the same tho.

Speaking from experience, I've tried fitting a R32 gtr clutch to a 32 Rb26 with an Rb20det box, I found the diameter of the input shaft to be different, the GTR driven plate wouldnt slide onto the Rb20det input shaft.

From memory there are 2 different sized/spline GTR clutches.

any idea if a 25 clutch kit will bolt up to a 20 flywheel?
