new to rx7s
 

i don't know much about rotaries, i bought 94 FD, and i lost the front rotor, i live SC, about 25mins away from the ocean, I'm not exactly sure y i lost the front. Because it dint make the return trip from NC where i bought it. I'm having a new engine put in, but would it be necessary to upgrade the radiator and install inter-cooler in it, just as daily driver?

Welcome to RX-7 Fourms! No, if you're just swapping a motor you don't need any upgrades at all.
