You have an uncle that works at mazdatrix and your asking us all the stupid questions? Why not just call him up on a weekend. And I'm going to assume slotted rotors are on the brakes and you just thought it was an engine feature.

I would definitely talk to your uncle at mazdatrix and im kinda surprised you havent already he would probably be able to answer all your questions easily. Does your car have slotted rotors on the brakes that is? I have to agree with Slow Rotor on this one ive never heard or seen anything on a wankle rotor being slotted.

I'm glad you cleared it up Karack, I didn't know.
I was once accused of running slotted rotors. Way back when in 1982, I was a local boy who was driving an RX2 in the 4 West Coast IMSA-RS races. That year I had a really good engine builder(Daryl Drummond) build me an engine. During practice, at Riverside, I was the fastest on the track. Another racer thought I was cheating and had the officials ask us to remove the intake manifold so that they could stick their finger inside and check if I had "slotted rotors"???...So we did, they checked, and everything was ok. So then, we weighed the car(after they left, of course) and I was 300 lbs too light. We sent someone to the sporting goods store to by some weights and came up to legal weight, then we qualified...3rd and finished 3rd.
Never did find out what they were looking for.

probably and to check the porting. the 12A engines already ran 3mm seals. the 86 and later 13B engines all have 2mm seals which can be a weak point in running more boost or just as a detonation protection modification. 3mm seals really do not provide any benefit in power, most tend to agree that it causes additional wear and less power earlier as the engine wears.

hey my FC is red too, also a single turbo. maybe they're cousins. 
anyways, when you look at the pics of the car, particularly the turbo (single turbo fc, lol) you'll notice that it lines coming from it, you turbo has both oil and coolant lines so it is indeed both water and oil cooled.
Don't get too worked up here, RX7 is not too noob friendly but you have a sweet car there. Take your time and read, read more and more as everything you have asked is very basic stuff. I too get curious when I have a new car but it's sometimes better to wait till you have very specific questions that you can't find the answer to before posting a thread like this. Lots of members would love to have that car and are gonna get edgey when you sound like you've never seen a car before.
You have lots to learn, but a great car to learn with.

I'm running 2 mm apex seals I know that much and no but that's one thing I will be doing is installing slotted brakes and my uncle / cuzins own Mazda trix I just don't want to call them up and seem like all i care about is the car I like to learn and do things kinda on my own I know plenty about cars but this is my first turbo my other cars were all larger piston engines or diesel idi like my Ford that runs on just about anything you can stick in the fuel tank still working on a glow plug system that's more dependable nothing like a 2/4 ton crewcab with a 6.9 that gets close to 30mpg I also own a 89 vert n/a a kick *** yz a old ambulance a pt and a Chevy work truck this 7 is just for fun yes I'm excited about it but I'm not about to screw with what a pro tuner has done I've ordered a few books if anyone has suggestions of what other books I should order I would appreciate it

And squat to pee and viagra for his wee wee ok back to cars books what books should I buy I know basically how the wankle works volume compression and all that and a little about turbos but not much I'm not asking about how to adjust or anything I just want to understand a little more about how it all works together and more then just tuning is about timing and injection now barkz my friend you might be able to help so get out your magnifying glass does anyone know where i can get info on my turbo ? That's not in jap ! Also I would like to have some schematics of welded rear diffs and where is the best place to buy switches and some interior trim pieces I need some for my vert especially the vert dial switch see I have a lot more to worry about then screwing with my engines

Thank you Aaron I already ordered the first one I was worried about the second one when reading it does it reference rotory or should i just imagine it as a 4 cylinder ? Same theory should apply correct ?

Street Turbocharging covers rotary engines. Being specific about an engine type is not what that book is about though. It is to teach you about turbo sizing, components of the system, calculating airflow, etc.

forget the turbo books, what almost everyone on this forum needs to read first is a book related to engine electrical functions. this is the heart of understanding how a fuel injected electronic timing controlled engine is about.
i can't point you in the right direction for what is the best, simplest book to help someone understand the workings of the system though. i learned it by working on them for decades of my life.
understanding that you can then move on to turbocharging books, as that is actually the most simple part of how the engine works.
i suppose having the turbocharging books already doesn't hurt but it hardly will explain much as far as the rest of the workings of the car go, the most important part of understanding the turbo system is that the timing needs to retard with boost and fuel enrichment is critical. oh, and too much boost isn't necessarily a good thing, even though it feels good for that single pass..

Makes sence I'm pretty familiar with a lot of n/a stuff as far as electrical stuff and a little of timing are there any books even if they are intermediate ?
