Reliability-wise, are 20Bs good? Are they better or worse with reliability, would you say, than the 13Bs in the 93+ RX7s? Also, how much power can one achieve in a 20B Twin, or Single, Turbo on Cali pump 91 octane fuel (I believe it's 91... like I pay attention when I gas my car )? Any help would be greatly appreciated. Thanks.

 

They are as reliable as any J-spec imported engine.&nbsp You do realize they are all used, imported engine into the U.S., right?

Same amount of horsepower across more rotors - always better for reliability and less stress on engine parts.

Stock twins will make close to 500hp.
Single turbo is a matter of how much money you got - 700hp+ is not unheard of.
Don't even bother trying to get this car reg'd in California - the swap is basically illegal in CARB's eyes.

There is a 20B section which you might get more answers from...
