hey guys just a quick question, is it at all possible to make the 13b engine sound like a traditional rotary or would I have to swap it out for say an rx7 motor ? Really just wanna know if I can make it idle like the brap brap sound

Do you have an example of what sound you're looking for? From the factory all rotaries sound pretty normal.

P.S. all rotaries this side of 1985 are 13b's.

I agree that they really sound close to the same. The RX-8 has a pretty quiet exhaust from the factory, much like an FC. Heck, the GSL-SE had a very quiet exhaust. The 8 does have a slightly unique sound but once you start modifying the exhaust system, you will see how similar they all sound, 12A, 13B, 13B Renesis...

Thanks I did not know that, erm I’m talking about the sort of rolling sound when the car idles. Sort of like a “wub wub” I guess if that makes sense haha.

You want it to have a lope like a V8 with an overly aggressive cam profile?

I think op is talking about porting on a peripheral engine.
You won't get that sound on a renesis...

The sound results from porting. You can do it on a Renesis, but it's a huge expense just for sound, so get informed on the tradeoffs porting brings, especially on a Renesis. You can google how all that works.
