all S-13's other than the ones with Rb motrs in them use basiclly the same motor mounts you can go to any part store and get them the main thing to wear out is the transmission mount the rubber bushing just goes followed by the motor mounts if you want a stiffer mount use Nismo ones cause some of the other ones i have used just make the car raddle if they are to stiff depends on what you are using it for race daily ect will depend on your set up
