HEY!!! i've got an idea........................"SEARCH".......yea.... .
The 1.1L is called the 12A rotary.
Its a 4 port,carbureted engine that was used for many years by Mazda and is considered to be quite tough,although most are getting quite old these days.It was used before the RX-7 in other rotary cars and was choosen for the RX-7 due to its reduced fuel consumption and light weight compared to the 13B(1.3L).
Factory HP was typically about 100,although it varied a slight amount over the 6 years it was used in the 1st gen RX-7.
Torque is around 104lbft...not bad for a small,non turbo engine.
The 12A was somewhat restricted by a poor exhaust system,small carb and mearly adequate ignition system.Its not at all hard to get the HP up to 150 without any internal engine work.You will likely fail any smog testing after doing so,and your fuel consumption will suffer,but a 50% HP increase is very impressive and quite fun in such a lightweight car.

"I don't know nothing" is a double negative, which means you do know something. Now that we've got the grammar issue out of the way, capitalization and spelling are always good. Let's work on that, m'kay? You will be less likely to get flamed around here if you come across like you can speak coherent English.
Anyway, yes, you have a 12A rotary engine. It's basically two rotors that spin in housings, rather than pistons that go up and down. Think of two hamsters in individual wheels running around, that's the gist of it.
Your next question will be "How do I get bigger hamsters?" Well, you can start by going to the archives and searching through the "How to modify my car" thread. Check out www.racingbeat.com or www.mazdatrix.com for performance parts.
