I am researching which rotary has the best reliabilty, best design etc over the years. I have had several 10B,12A's but never a turbo car or a 13B car. I am building something kinda off the wall. The car will be a 30's styled track roadster with a rotary. If you could pick an all around driver/performer what woul you use and why?



Thanks

the 84-85 gsl-se's rutinely go/went for 200,000+ miles, i can list many many examples with 250+



the 86-91 non turbos are the next most reliable

 

i'd go with an streetported S5 non-turbo engine with exhaust and a custom intake setup.

 

i agree with ^^^ Next best would be the s3 rx7 12a's

 

Series 3 12As, in North America at least, had a horrible oil cooler that cooked the dowel pin O-rings and the filter pedestal (now oil cooler) O-rings resulting in massive oil leakage.



This isn't so bad, except for how it leaks directly onto the coolant hoses beneath the oil pedestal. I have seen new heater hoses deteriorate to the point of failure in as little as 6 months, and that on a "mildly" leaky engine. Nothing much good has been said about rapid coolant loss due to hose rupture while at operating temps.

 

but its lighter and cheaper to make!
