Re-using these rotor housings
Has anyone reused rotor housings that have this type of damage in the exhaust port area. I have a couple of housings with this type of damage, wanted to know if they could be used to build a not so perfect engine.
Seeing that the damage is not in the compression or combustion area could they be used if the marks are completely deburred?
I am sure some of you guys have done this before and have relative success.
Let me know.
Yes i have and am currently. Like you said and I agree there not on in the compression or combustion area so you will be fine.
I have taken apart a factory mazda reman that mazda reused a housing that had a nik above the exhaust port and it does no harm.
So feel confident that it will work cuz i do. Especially when i have 500hp being cranked out of my current rx7 with that housing in it

Will it run fine, yes. Have I dont it several times on personal engines, yes. WIll it have a long term negative effect, yes. Is that negative effect a major problem, not sure.
If you use a housing that has a couple long deep gouges near the exhaust port it will eventually cause the seal to mis-shape(best way I could describe it) and start to wear the compression/combustion area of the housing. It will cause uneven surface wear on the rotor housing but it is minor and hard to really know how much compression is lost due to this. This info is from one of my personal engines I had about 7k miles on using RA Superseals. Keep in mind the SuperSeals are already hard on housings so maybe they magnifide the issue.
Long story short, install some ALS seals, run the housings you have, crank up the boost and enjoy.

Well I guess I should not throw away these housings and keep them for a rainy situation in the future.
Whats the best method to check for highspots around the gouges and what tool is best to level them?
