I personally think that's the joy of it. .....Run to a drag....wrench on it later.......They are Not reliable compared to conventional "Rod and Piston". .... But, you are not going to get the rpm nor the "broad" band of power. I like wrenching. Do I wanta do it to my daily driver...No.....But, my weekend warrior.....Hell Yes! I love it. I only hope the "Ausie's" and people like yourself, can keep this "Little Mighty" going for All of us to enjoy. Thank You Very Much for the Video's.......Keep it Up!
Why don't you use US Chrome to replate housings? They have the capabilities and would certainly do it with chromium, electroless nickel, or tricom. Chromium can be put on 20 thousandths thick, tricom can be up to 30 thousandths. Housings could be re-ground to factory finish. This is especially useful for 12A housings and the only solution for 10A housings.
Nice work all for the love of Rotary.i have three rx7 job and a world record hp.on my 13b on e85.keep up your good work brother.my videos are on UA-cam under Peter laquis world record.and Peter laquis 20b.god bless from TRinidad and Tobago.
okay looking good but what about clearances? how good will be compression? and for how long will a housing like this last? do you have to use different apex seal springs for this to work?
The amount of material removed is less then .002. This does not effect compression at all. Hosing will last less then brand new of course but will last 2 times longer then if you used a worn housing the way it was. No standard springs.
adam, question... what are the benefits of re-grinding vs honing them? are they used in different applications in regards to housing damage and do you offer honing too? thanks, and love your videos man keep them coming!
Easy..there is no such thing as honing a trochoid . Even if there was it would be highly unlikely that honing tooling would penetrate the hard chrome properly
Does Mazda still continue to make parts for the older engines? Can you buy a 12A housing for example? I see Mazda kept the casting in the housing for the peripheral exhaust port for the RX-8 housings in your video, does this mean those housings can be modified for use in older 13B's?
i wanted to see the process, but mainly because i was curious if your making a cross hatch type pattren on the apex seal surface or its its a straight line all the way around, i dont know alot about rotary engines but i find them quite interesting, i am more into diesels, now that being said think its possible to make a diesel rotary? have an injector rather then a spark plug and high compression ratio? xD?
No cross hatch on ours no cross hatch brand new from Mazda either. I know a guy who did a diesel rotary. RPI International also did a 580 ci 2 rotor that was built as a prototype for a US military tank project. It was for turbo diesel and kerosene use
how much would it be to refinish a set of RX-5 13B housing and powder coat in bright yellow? I know just painting would be simpler, but I just want a nice finish that will last as the paint on my housings now is chipping pretty bad in many places
original is nikasil, who was invent by Mercedes Benz for the C111 engine, chrome is a very old method , low cost plating , use normaly in steel or cast cylinder, not in aluminium Wankel housing...
@@leneanderthalien Chrome is a "loose" term, the steel liner is electroplated with a low wear metal. Modern jet engines are "hard chrome" plated, maybe with NikaSil, which is a product trade name, not a process, to the best of my research.
Rechroming cost vs. new housing cost varies depending on the engine it's for. So far goopy is the only one that actually offers rechroming at $575 per housing. Now if you're just trying to ressurect a pair of NA FC housings, then sure, buy new instead of rechroming, but if you're like me and have a 40 year old RX-5 13B which all parts for it are NLA and the only option for new (old stock) housings is priced at $1,000 each (and very hard to find as well), then the resurfacing or rechroming options look alot more attractive. Now i'm not disagreeing with you whether or not new is the most ideal route to go because it is, but alternatives such as these are just more cost effective and perfectly fine depending on the application.
could you do some 4-rotor engine builds, and i think your customer base would significantly improve if you had some way of promoting your shop, like racing rotaries that are massive one-offs, or building SEMA-winning trophy engines that make upwards of 1500 hp, every year upping the power, reliability, innovation, and application abilities. some story-line rotaries would be awesome too, like something where you buy a really beat-up rotary, and apply it in some sort of high-end application, so that you give you customer/fan base a chance to fall in love with a project of yours, and watch it grow from a beat-up FD to a winning drag engine. Just saying, markketing is a big deal when it comes to rotaries, coz there is barely any money earnt in it if your not professionals with high standards, a good customer/fan base, and a good reputation. somewhere good to start would be something along the lines of the engine that you previewed in one of your hour-long 3-rotor builds that was your personal own engine, because it shows that 1 you love working with rotaries, 2 you know what's important when it comes to rotaries, and 3 that you can professionally complete a build up within a reasonable timeframe another good place to start would once again be a beat-up, run-down FD engine, because although it doesn't show as much that you know your shit, unless you heavily modify it to drag, or whatever, you also show that you can work with anything, literally
Appreciate your suggestions. Im personally not a fan of gimic 4 rotor engine kits. These are 13B parts stacked together. Gear support is weak and cooling the back rotors is uneven and crankshaft and bearing problems occur often. I can push a 3 rotor factory engine harder and longer and further then a 4 rotor gimic engine. I have done a 4 rotor and had issues with the eshaft tapers . We do however offer a true 4 rotor all auminum PP road race engine with custom dedicated intermediate housings to hold special gears etc. The issue is nobody wants to spend $50k so we dont market it heavily.
well just builds and storylines instaed, coz i think they would up your fan base massively. if not keep doing what you're doing, coz what i'm saying is just a bunch of suggestions for growth
chrome? no: The factory housing is recover with Nikasil (nickel-silicium carbide) who is MUCH better high resistance an low friction) than simple chrome (who is only use on conventional piston engines...) ps: i use the scientific name silicium because in english silicium is called silicon=rubber silicone in all other languages...
I think you mean my aluminum engine with the 13G crank and gears? Its not an actual 13G but the alum engine will be getting worked on...and filmed...soon. Stay tuned!!
RX7 Specialties: YAY! I hope you make a full feature length film with lots of commentary on how and why you choose every single aspect of the build. I know that is a bit of a tall order, especially when you have to work while you talk, so don't hesitate to do voice-over on bits a and pieces where the footage turned good but the sound/dialogue isn't up to standards.
Sounds like a rip off !! To much talking abt fixing not enough fixing!! Oh Ur house is no good we just keep it for you save u the return shipping!! And stack it on shelf and sale it back to ya wiped off!! Better just go to junk yard!! Or buy after market?? Guessing you use factory size replacement parts?? Or talk abt all the sizing up may be over size???
This video is intended for rotary car owners who understand the need for the service. BTW no such thing as aftermarket and we have performed this service on over 300 housings...all of which benefited from doing so
.@Scotty.. Talk is cheap money buys the whiskey.. Easy talking when you don't even own a rotory which means you're a poor ass talking nonsense about something you've got no clue about . This guy provides a service to us rotory people who spends more money on our engines than you earn in a year to prevent catastrophic failure because we are smarter and experienced and above all qualified!!!!
Had these guys machine my housing and their work was excellent, saved me a fortune on replacements. Also nice to deal with a Canadian company.
Ooooo. Shiny housings. Love the lighting and the camerawork!
I bought them resurfaced and they are great.
Excellent
wow. incredible. will definitely consider getting this done when I rebuild

Have you ever done or would consider the RE5 chamber they are prone to cracking in the spark plug area and the usual chatter marks.
Is there a coating honing takes off. Will coating be removing by hand honing with sandpaper an rolling pin?
okay looking good but what about clearances? how good will be compression? and for how long will a housing like this last? do you have to use different apex seal springs for this to work?
The amount of material removed is less then .002. This does not effect compression at all. Hosing will last less then brand new of course but will last 2 times longer then if you used a worn housing the way it was. No standard springs.

RX7 Specialties thank you for the explanation!
Anytime
Still hopeful that someone who has had this service done to their rotor housings will give us here some feedback.
How do you guys usually receive and ship the housings? Best choice
If you'd like detailed packing instructions you can email us, we would be happy to send them your way
Does Mazda still continue to make parts for the older engines? Can you buy a 12A housing for example? I see Mazda kept the casting in the housing for the peripheral exhaust port for the RX-8 housings in your video, does this mean those housings can be modified for use in older 13B's?
Mazda still makes many parts but if your talking really old youd have to find it. We have lots of older stuff
What happens if the housings are painted or powder coated previously?
I know this might be dumb to ask but is there a process that rechrome it face
What type of liner does the rotory use from the factory?
chrome
@@rx7specialties203 it is actually a steel liner, cast together with the housings, then chromed !
i wanted to see the process, but mainly because i was curious if your making a cross hatch type pattren on the apex seal surface or its its a straight line all the way around, i dont know alot about rotary engines but i find them quite interesting, i am more into diesels, now that being said think its possible to make a diesel rotary? have an injector rather then a spark plug and high compression ratio? xD?

Wouldnt diesel rotary be a better concept since diesel has lubricating properties that gasoline lacks?
Great for lubrication but lousy fuel for the design of the engine
how much would it be to refinish a set of RX-5 13B housing and powder coat in bright yellow? I know just painting would be simpler, but I just want a nice finish that will last as the paint on my housings now is chipping pretty bad in many places
email me for these prices please
I have to the email on your site, but received no response. is there another email I can contact you at?
I also needed some machine work done as well on a set of rotors
That is odd?? we always respond. Maybe send another and well address your questions Sorry A
No problem ..happy to help...
Will apex seals be better softer to housing re grinding?
Unfortunately not...the chrome remains the same hardness
Need my housing cleaned up where can I get the all the info
If you're thinking of sending them to us you can shoot us an email, adam@rotaryengine.com
How much does it cost
Is this service still available? Dec 2020
So you are just re-grinding the original chrome, not re-chroming the rotor housings?
Are they still around 😪
is it possible to build a 5 rotor with 3 turbos? just wondering
For what purpose?
RX7 Specialties funsies lol
anything is possible with cubic dollars
Well there’s 6 rotors and 12 rotors but even building a 4 rotor will set you back $50,000 minimum...
ah, i wanted to see the actual process.
HaHa..not today Josh
@@rx7specialties203 what the 4inch grinder??
Can someone give me the paint code on the 1st housing 7:32 (from left to right) or simply the paint name?
how much do you charge?
you can email us directly at info@rotaryengine.com and we would be happy to answer all of your questions about pricing there
Would Nikasil lining better than Chrome?
original is nikasil, who was invent by Mercedes Benz for the C111 engine, chrome is a very old method , low cost plating , use normaly in steel or cast cylinder, not in aluminium Wankel housing...
yes and nobody does it to a rotor housing.
@@leneanderthalien Chrome is a "loose" term, the steel liner is electroplated with a low wear metal. Modern jet engines are "hard chrome" plated, maybe with NikaSil, which is a product trade name, not a process, to the best of my research.
@Sean Price you need to do more research, not just regurgitating a web page!
@Sean Price Nope, hands on experience with aerospace plating.
removing material is not good. Re chroming this is the way..
Its an inexpensive alternative. Have you ever rechromed a housing before?
never
Well Im not surprised. Nobody really does it because its costly and not economical
Cheaper to buy a new housing than rechrome.
