my mate had a 1200 sedan with a rotor in it, it wasnt all that bad on petrol unless your revving the hell out of it all the time, i dont like the idea of rotors in dats much either, id much rather a worked L's series or ca. stick with nissan. also his was an aspo 12a and he couldnt get it engineered anywhere cos they suppodely classify rotors as double wat they are or something like that. 12a being classified as a 2.4, thats what i was told anyway. also his seals were stuffed as is the case in alot of them, he couldnt rev it above about 5000rpm or it would bellow smoke. not much point in having a rotor if you cant rev it huh hahah.
