Other than the spotty carbon deposits, the machining marks are clearly visible in the rotor face.
The round corner-seals are an important part of the sealing function of the engine. This connects the three side seals with the apex seal. The execution of the tolerances, installation, and components are key factors in the compression of the engine.
The aluminum rotor housings were in good condition, as they should with very little time on them. We can see the small oval exhaust ports. Porting these will yield improvements in flow and power.
The center iron has these small “Primary” ports that feed air into the combustion chamber.
The stock porting leaves a lot to be desired. These sharp edges and ledges all affect flow and power. Cleaning these up with a simple street port yields substantial gains with minimal negatives.

Good luck! so sorry about the fire mishap.
Looking good 😊
I love how this project went from “OEM+ Restomod” to “make our rotary engine one of the most highly-modified 13B REW engines on the planet.”
Yeah, fires, pulling the engine, downtime, boredom, and beers have the effect of changing the strategy. lol.
We originally planned on retaining the stock motor for a while, do a lot of baseline testing and comparisons and then slowly upgrade the fuel system, turbo, and other bolt-on parts. Since the engine was out, we decided to tear it down entirely and go for an extreme build instead.
