I dont see anything wrong with rotors...well apart from the fact they sound like overpowered lawnmowers aspecially when ported

. If you love rotors and know enough about them then i say go for it, I woudnt put a rotor in a datsun myself, i would rather go with something that has torque e.g 308 v8,350 chev v8 or a SR20DET. in the end it comes down to this, our love for datsuns and thats all that matters in my books.
