Hello, I live in Israel where mazda never got to bring the rx models.
My friend has a rotary engine in his garage which someone brought something like 7 years ago from a working car, he's not sure what car it was taken from.
I looked at the engine, looks a little bit corrosive on the outside but nothing special.

My questions are:
Should I start this project with a 13B RE?
I'm not really sure it's a 13B RE but from what I read online it seems like the right one (it has mounts in the middle and looks a little odd).
I want a powerful car, with available power at low and high rpms and as reliable as possible in rotary terms.

The engine came without the turbocharger(s?), what turbo should I get for it to work the right way?

Does the fact that the engine stood without starting for some years affect it in any way?

The engine has something that looks like a fuel injection, should I try and make it work or just put some carburetors?

I read something about a pump called OMP(oil metering pump) which pumps oil into the exhaust in order to extend the engine's life.
Is it something I should look for?

Thank you guys so much for the help.
