What kind of bullshit comparison is that?
The RX-3 was produced throughout most of the 70s (till 1978). At the time, Mazda has also produced other rotary cars including RX-2, RX-4, and the REPU (rotary pickup!). It was in 1979 that Mazda decided to produce a pure, lightweight sports car with a similar vision as Colin Chapman had with lotus. The RX-7 was born, and it was an affordable 2 seater with a similar goal performance-wise of the Nissan 240z. The RX-7 sold like hotcakes from 1979 to 1985 (1st gen) because it was affordable and somewhat quick. Yada Yada Mazda came out with the 2nd gen which was a bit heavier but the Turbo II was quick for its time (1987-1991) and one of the best handling cars of that era.
Then of course that leaves the FD RX-7 (1993-1995) where Mazda saw the NSX and 300zx as threats and stepped up the performance with a lightweight (sub-2800 lbs) pure sports car that " didn’t just win the numbers game, it humiliated the field" when tested against Corvettes, 300zx, Porsche 911.
... and you dont need an LS1 to make good power in an RX-7 ..
The Evo, in a lot of respects, is similar in goals of the RX-7 - fast, good handling, affordable. But it is on the opposite end of the spectrum when it comes to looks and general layout/packaging.
About the only thing the RX-7 and the RX-3 have in common is the rotary engine.
