i have some bad news for those who want to install 70cc in their gtrĀ“s all the 70cc have the potential to fit but one of the tubes the the prestone hose goes on to is made on the side on all 70cc for the gtr and it does not fit soo if you want one you have to machine it,and what i mean about that is you grind that piece off and block the hole,then you drill a new hole and put the piece on there,and if anyone is in for the journey i have a 70cc due plus which i can sell for cheap (around 320 canadien)if you are interested let me know
