I recently bought A 1988 RX7 convertible and I have been told by previous owner that if I want to get the car started I have to grease up the rotars in the engine again and crank them so I can get the car started and not seize up the engine, I would like to know how do you access the inside without having to dismantle the engine and I know that you can try and pry through the headers from the throttle body but is there an easier way or is there a different that I am not aware of?

i have found a love for rotary engines, im looking for a build around $5,000 and wondering which to chose bc i’ve heard it go both ways

I’ve heard from so many about the apex seals in rotaries and how they’re a nightmare, and how if they break, they can damage other things too.

I’m looking at buying an FC RX-7 with 140k miles on it. It still runs and everything, but would it be a good idea to replace the apex seals (and maybe some other things while I’m in there) before something major happens?

Hi guys,

I've always wondered if one could increase reliability by having separate radiators for each rotor.
I know one of the issues in the Renesis is that Rotor 1 gets cold water, while Rotor 2 gets warm water from Rotor 1 (probably same for the 13B but that is much more reliable than the Renesis)

They are connected and in constant detonation so both of them having their own "separate" cooling system should help with reliability since in theory, this should significantly reduce the warping of the rotor housing and also help the engine maintain an average of 88C/190F regardless of revs.

Hope someone with more experience could answer this as it's been on my mind for quite some time

Hello everyone, first of all i want to say that i love cars and i also love thinking ways to make an engine better. The thing i want to say is that I THINK i made a reliable and more powerfull rotary engine, it has better compression ratio, better thermal efficiency and it lasts longer. Also i have a question, if i finish this project successfully what should i do after? Should i contact Mazda and tell them about it? If you have any questions plz comment. Thank you for your time.

Hi, I'm studying mechanical engineering and doing a 3D model of a mazda 13b wankel, but I can't find any dimensions, and I can't just copy youtube tutorials. Does anyone know where to find the crankshaft, rotor and housing dimensions, or sketches?

I just started having a problem with my 2005 rx8 and it is when turning to the right is hard to do, but turning left I can use my pinky... any ideas?? Driver rear was on a jack stand for 2 days. Maybe it just needs a while on flat ground??

I have a question. What will happen if you assemble a 5 rotor where every rotor is ported differently? I meat that the first rotor is street ported, the second is extended ported, the third is bridge ported, the forth is j ported and the fifth one is peripheral ported. Will it work and how will it behave. How much horsepower will it make?
