any modified car is a pig in trafic. as for the weight of a ca18 vs a 12a ( both na engines). the rota is heaps less. how many modified cars sit in trafic and dont overheat

there is pros and cons with every motor and every modification.

if you look at all the rotor guys who have gone 2jz is the guys who own the rotary shops. example craig dyson from dyson rotary and also maztech have gone that way aswell. gas motorsport made a deal with them to run the cars

these guys have been racing cars since the early 90s. and i dont think they find it hard to find parts.

any motor cost big bucks to build if you want it done right. there is heaps of blokes who rebuild rotors on the cheap and have no drama. if they were that unreliable why would they build the rx8
