There are many different models of RX7, so this section is probably full of mistakes!
To avoid upsetting the pedantic, please make sure you use the correct terms. There have been three GENERATIONS of RX-7. There have been 8 SERIES of RX-7, each generation has had more than one SERIES associated with it. (thanks to Henning!)
The associated dates, and numbers registered in the UK as of 2000 are:
|1st Gen||1978-1985||2312cc||105||125||10.0 s|
|1st Gen GSL-SE||1984-1985||2616cc||135||130||8.8 s|

The 2nd Generation is the only one with a convertable option. In the US this was non-turbo, whilst in Europe it was Turbo only!
All standard engines found outside Japan are twin rotor, with two plugs per rotor, both in the same combustion chamber. Two plugs are used to improve the burn characteristics in a very long, thin chamber.
The first engine used in the Rx7, with two 578cc rotors. Will give 150 BHP with decent twin carbs.
Introduced in 1983, and used throught the 2nd gen model series. This engine has several variants, including additional intake ports and turbo versions.
Still using the basic 13B engine, REW is a japanese abreviation for Rotary Engine Twin (turbo). All the 3rd gen Rx7's to date have been Twin Turbo (unlike the TurboII 2nd Gen).
This is a 3-rotor version of the 13B engine, only made for the Japanese market.
Mazda are still making Rx7s, but they are only available in Japan or Australia. There is a Rx-01 concept car, and now the Rx-evolv, with a new 13BMSPRE (Multiple Side Port Rotary Engine) offering improved normally aspirated performance, and it seems that Mazda are committed to continuing with the rotary engine
