13B REW swap is finished
I would be totally happy with 300WHP from an engine that lasts 100k miles. Flashing new targets into the stock ECU so the car constantly chases the optimal tune is a big step towards that.
However, the design of the Renesis (e.g. high compression ratio & weird exhaust ports) will always be problems for FI long-term reliability.

Everyone has been hurt at some point, when trying to make boosted power with a rotary. Time will make the renisis reliable. And for whatever swap you are comfortable with, then do it.
As for relibility..... It is up to the tuner and owner.

i am a personal owner of two RX7 and by any means would i call a 13brew realiable... ive been through 2 motors. then i converted to a LS7.. which im currently working on....
ive seen these motors go with under 10k and under 5k... especially when you start making power **** breaks.
these motors built from a reputable shop can be anywhere from 3500-5000 dlaars depending what you are looking for..
i tihnk it is impressive but if i were gonna thorugh that kind of money into it i would went a different route. amybe LS or maybe sr20.. but personally RX8 isnt my cup of tea
good job and good luck

Merry Xmas.
Here is some pre xmas tuning. This engine has 60 000kms of hard thrashing. The car has gone 10.04@147 with 690rwhp. Over 100 dyno runs and 70 of them ar over 500rwhp.

....waiting for all this snow to melt. I know I'd have to get different tires if I wanted to drive it now.

Yep. 300-350WHP for 100k+ miles isn't a problem with the non-Renesis 13B.
I want to hug your engine. Don't know why but joy joy feelings are emerging at the possibility of that much hp in my 8. being as my 8 is now my daily driver, this is no longer a possible dream for me.

But it did 850 20 times back to back. And anything would not be streetable at 1000hp.
It has spent its life a 400rwhp. This is just an example of how reliable a rotary can be at these levels.
The 8 is cool, but it would be complete if you could make it move at a quick rate for a long period of time.
Cheers.
True it is a dyno queen at 874.

For me, I am happy with the way it is, so I guess that's why I have turbo 8 and not a mustang or an RX7 like that one.
I would never need all that power, and could care less about numbers.

No one with a turbo Renesis is likely to get 100k miles out of it...50k+ might be more common with the Accessport & the GT3071r upgrade (props to MM).
At least now we can rule out bad/erratic tuning and a ****** turbo (18g) pushed out of it's efficiency zone. What's next is to see if there is indeed a problem with the exhaust ports and/or heat soak on the rear rotor which creates asymmetric thermal stress that eventually results in a grenaded engine.
Since the goal is to shove as much air/fuel into the engine as possible per unit time and combust it safely, the higher compression ratio of the Renesis rotors will always be fighting against that. All other things being equal, it's easier to get a higher mass flow rate with a lower compression engine (to a point).
Some day when I have cash again I will have another go at making a fast RX-8. When I do, it will be with a pre-Renesis 13B and a numerically lower rear axle ratio.
I agree with you 100%!!!
