at the end of the day it's still the same thing without the mud slinging.

for a renesis you'd need very good low mile housings to even consider the service, this is mainly due to the thickness of the MSP chrome and the fact that the housings wear more rapidly than any previous designs due to the higher average revs of the MSP engine.

Mudslinging? This isn't a campaign here. Also, I only corrected someone when they mistakenly assumed it was Goopy. Mudslinging is the use of insults and accusations; it's quite the opposite here as there's no insults or accusations, just pictures. Anyone and everyone we've done machining for that has experienced our process calls it "night and day" from anyone else. What's wrong with providing a really incredible service with extra steps included for the same price?

Hello. Not to bring up an old thread but do yoh still do rotor housing machining? If so, how could I get them done and such?

so I'm new to these rotary engines, so please help me. How exactly do I know if my rotor housings are able to be used again? I bought a 04 rx8 automatic prior to finding and reading these forums so now I'm in sort of a desperate situation. Thanks

Zeox

first things first is get familiar with these engines. look at all the stickys in the new members subforum. second, get a workshop manual and read it over and over to understand how the engine works and what goes where. theres a link to them around here somewhere. third, figure out if your current level of mechanical ability is sufficient to take on the task of rebuilding this engine knowing what you do after reading the stickys and the workshop manual. if you are not comfterbal around electronics, fuel systems, transmissions, coolant systems, and basically every system on a car, this may be something to bring to a reputable ROTARY shop in your area. if you find yourself as someone who basically eats their soup with a wrench then you should be ok so long as you do things right. now finally, if all that hasnt scared you off yet, then you will have been equiped with enough knowlege to either know the answer to your question, or know how to find it.

that all being said, welcome to the club, and i hope you can get your situation sorted so you can enjoy your rx8 like we all do

If you tear the engine apart then you can inspect it and see if you want to reuse it. You don't want to see anything like scratch marks or chrome flaking off.

Depending on the condition a Mazda reman might be a better deal, but the 4-port(04 and 05 automatic RX-8) remans are more expensive than 6-port, and no, they are not interchangeable without swapping a lot of stuff over.

So once I clean the housings (hopefully tomorrow) and I dont see any scratches or chrome flaking, is there anything else I should look out for. My dads a mechanic but never has worked on rotaries ever so this is a learning experience for both of us plus my brother who also bought one.

I am currently reading as much as I can every day because since I am still in school I don't have a bunch of time. There isn't a shop here in SD that I'm comfortable with but read of Lucky7 Racing up in LA. Thanks.

Zeox

depends how deep you wanna go really. look for signs of oil starvation. make sure the seals all fit where they should without having to force them. check the bearings for grooves or copper colour, once in a while they even spin. dont lose the keys that hold various gears in place. make sure you have the engine stand adapter, very helpful. also an endplay washer kit should be in the budget. theres no timing for you to worry about so thats good lol. beyond that making sure everything is within specs is a good precaution. theres plenty more but thats what my tired brain can thing of right now lol

Zeox

oh amd swap the thermopellet for a always open one, cant for the life of me remember where you get them, but its a good idea.

Castle_ofKingEdgar

ok thanks man

Just got mine back from resurfacing. But I have a pretty big scratch on both housings. Are these still usable? One housing is about a 1/4 of the way around and the other one is about 3/4 of the way around

eaymon

can anyone share their experience with resurfaced housings? people say they wont last more than 10k miles

i know of 4-5 rotary shops that provide this service, but if the engine is just going to require another rebuild in 30k miles, then whats the point?

i'd like to hear from people who have actually gotten it done....

The housing you see above is not worth reusing IMO . If your housings have a groove like that or missing chrome on the sides ...no amount of resurfacing will fix it. Pretty much any Renesis housing that's done more than 60,000 miles is going to be toast , you will have to be lucky to find any good enough to re-use. But if you do, resurfacing is a good idea and i have had several go through that process and come up mint.

eaymon

what about 59,375mi? :P

have you gone through the process yourself?

Yes , like I said , I've had it done multiple times on recoverable housings and got great results.

At that mileage ............. you might get lucky. But any rotary rebuilder worth his salt will be able to tell you if they are recoverable or not . Those ones pictured ...someone is being VERY optimistic but maybe after 10000 miles compression will enough such that it will hot start ok.
