Mazda hasn’t done anything to squash the rotary engine rumors flying around the possible new RX-9. In fact, as of a few days ago, an executive from Mazda confirmed in more or less words: Yes we are working on it, and it is moving along to a more advanced stage.
Let’s review what we have seen so far.
Hybrid Drive Train Patent dated September 2016
Mazda basically penned out a drivetrain setup for the next generation of Rotary vehicle. There was also a rotary specific i-stop type patent entered as well. The only problem is we have seen something contrary to this in the next topic which makes this puzzle interesting.
Rotary Turbo Patent dated August 2015
This patent got everyone (including myself) really excited. Top exhaust ports, a turbo mounted to the top, rear wheel drive, and it is screaming for a huge upgraded turbo to be sticking out of the hood….
One can dream right? I digress with that path but looking at this patent Mazda was working on a different variant of the engine and thought it was important enough to file a patent on it. It should be noted once again this patent was from 2014.
Dorr Support Structure January 2017
The last patent popped up recently and it suggests a lower slung sports car as it moves the door up at a 15% angle and uses a torsion rod to hold it open. The only use a car would have for this is if it is low and you don’t want to hit your doors on curbs when you open them.
Looking back further we can see other patents from Mazda which point towards the continued research of the next rotary with laser ignition, different configurations of the engine, the 16x, etc.
Recently at the Mazda tech forum in Germany, Mitsuo Hitomi from Mazda confirmed that the development is in the advanced stage.
It looks like Mazda is willing to say they are still working on it, but not willing to say, “Yes you will have an Rx-whatever on this specific date.”
Adding to the fire, several Japanese magazines have been saying the Tokyo Auto Show will have the next car at it as well.
With more and more pieces to the puzzle being revealed, perhaps this will be the year we get to see the next RX. My money is on the strategy that it will be teased much like the RX-Evolve and the RX-Vision were, and we will get a real car and one heck of a surprise at the Tokyo Auto Show.
A guy can dream right?!
RX-9 Rotary Engine Puzzle: Confirmed? September 12th, 2017Derrick Ambrose
Although normally we have a ton of technical information for you, this time around, we wanted to take an opportunity to share with you an awesome customer story we had happen a couple weeks back.
CorkSport is all about growing our family base, and constantly trying to connect with our community. Let’s be honest, we are here because of our family of customers, and we will continue to be here as long as our family is as well.
As most of you know, our company runs on internet-based sales, but we are also present Monday through Friday in the office to field any walk-in customers we may have. Anyone is welcome to come visit us at our HQ, and also to pick up parts we have in store. Most people wouldn’t guess that we have a showroom, but as you walk in you can see an exhaust hanging from the ceiling, and a handful of parts we display on the shelf, so people get an idea of what we do in-person.
We would love to see more people come through our front doors, and we welcome anyone from anywhere to come visit us.
A couple of weeks ago, we were paid a special visit from a customer named Rick and his wife, who came all the way from South Carolina on some business, and wanted to stop by CorkSport while they were in town.
Rick and I had a conversation about adding some Drag Bags to the rear of his MS3 in order to keep it from rubbing. He later called and told me it worked perfectly and thanked me for my recommendation. Rick has a first generation Mazdaspeed 3, and he was wondering what type of modifications he would need in order to make a certain whp. After chatting with him for a bit, and giving him a list of parts he would need to reach his goals, we decided it would be a good idea to snap a couple pictures to make sure we saved the memory!
After Rick and his wife had left, I realized that those are the types of experiences and interactions that our team at CorkSport loves.
It was very refreshing to talk with a customer multiple times, and then be able to put a face to the voice on the other end of the phone. This is what CorkSport is all about. We are here for YOU. We want to see you succeed.
CorkSport takes a lot of pride in making sure our customers come first. It’s also our highest priority that if you as the customer ever feel like you are not being valued like you’re “Number One”, we will do what we need to in order for you to feel that way.
CorkSport wants to make sure the entire community is part of our family. We would love nothing more than to hear our customers feeling like they can come to us for anything, just like Rick did, because well… that’s what family is all about.
Why CorkSport Loves Our Family Of Customers September 7th, 2017CorkSport
Since 2013 and the loss of the Mazdaspeed 3, Mazda has really left a lot to be desired as far as power goes for its line-up.
Don’t get me wrong, we love Mazda here at CorkSport; the interiors and exteriors are on point, they get great gas mileage, and are exciting to drive. We will always continue pushing and developing the platform that Mazda is kicking out, but let’s be real…we love power.
That brings us back to why I am writing this exciting blog… Sky-G is getting some TURBO LOVE.
I’ll admit, we thought long and hard about moving forward with such a large kit. We hoped, we wished, and we dreamed that Mazda would eventually wise up and kick out a GEN3 Mazdaspeed, and we got really excited when we heard about the CX-9 Turbocharged 2.5L engine. Unfortunately Mazda chose not to go down that path; once we found out about that, we decided it was time to pull the trigger on the GEN3 Mazda 3 & 6 Turbo Kit.
Moving forward on a project of this size was not a trivial decision. There were many aspects to consider:
Do we make a complete kit or just design and manufacturing difficult components?
What is the right power level to shoot for?
How will the engine and drivetrain hold up to the increased stress of forced induction?
How do we properly tune the engine?
These are all important aspects we had to consider.
Let me lay out some details and choices we made.
The most difficult and time intensive aspect of the kit is designing the physical components that will make up the kit… the entire kit. And yes, we decided that a 100% complete kit was the only way to make this a great setup, so that exactly what we intend to provide.
A complete kit needs to include everything from the air filter to the downpipe, and everything in-between. This includes the intake system, turbocharger, intercooler piping, intercooler, exhaust manifold, downpipe, and all the necessary silicone couplers, hardware, and wiring extensions.
This will be the most complete turbo kit you can purchase for the 2.5L SkyActiv-G powertrain.
Right behind developing all the components for the kit comes the tuning. We are working with Versatune to develop the software to control the 2.5L Sky-G engine with forced induction. This portion of the project will be kicked into high gear in the near future once all functional prototypes are on our test car and strapped to the dyno.
Lastly, some thoughts to consider:
Will the engine take the added power?
How much will it hold till it pops?
Time will tell on those questions, but we do have some stuff in the works that will help. However, just spit-balling here, something around 280-300whp would be a lot of fun in the Mazda 3 and Mazda 6.
Stay tuned as this project evolves through testing and development in the coming months.
What are your thoughts on this new project? Questions?
Leave them in the comments section, we would love to hear from you.
I have only skimmed the surface of this project and I could easily write pages and pages if time allowed.

Turbo Kit in Development for 2014+ Mazda 3 & 2013+ Mazda 6 September 2nd, 2017CorkSport
If you have a Mazdaspeed, then you have probably heard about cleaning your valves a time or two. You may be asking yourself, why is it that I need to do this? What is it good for? Or why do my valves get dirty in the first place? I’ll be covering all of that in this blog post today, along with full instructions on how to perform the job.
Why do my valves get dirty?
They get dirty because our engines are Direct Injected. This means that the fuel is injected directly into the combustion chamber, rather than in the ports. This also means that there is no fuel passing over your intake valves, and those nice detergents in the gas that are advertised don’t do anything for you.
That being said, Carbon from the EGR (Exhaust Gas Recirculation) system and oil from the PCV (Positive Crankcase Ventilation) have free reign to cake your valves.
Figure above is an example of a dirty valve after approx. 80k Miles with no EGR delete or OCC.
Why do I need to do it?
If enough time passes without any preventative treatment, the valves eventually can get so caked with carbon, that it can start interfering with proper air flow, combustion, and even the valve’s ability to shut all the way. Intermittent misfires, knock, poor fuel economy, and loss of HP are all symptoms that can occur.
What products do I need?
I’m glad you finally asked that! Go ahead and get ready to start jotting down some notes on the things you will need! Most of these can be found locally. *You will need a Shop-Vac, and an Air Compressor.
1. Media Blaster – This is just a gravity fed gun with a hopper. Powered by compressed air. As you squeeze the trigger, the media falls in and goes out the blaster. You can open and shut the media valve in order to Switch between media and air only.
2. Media – You will want to pick up some of the 24 Grit Walnut. Do not get the 12 Grit as this is too large, and you will continue to jam up your gun where the media falls from the hopper into the barrel. The 24 will have “Fine” In the top right corner.
3. Long Picks – You won’t want to start blasting right off the bat. You will want to soak the valves for a little bit and get in there with some long picks to really start softening up that initial built layer. You order the picks online and these are a lot easier to use than the little scribes at Harbor Freight which have always felt too short to me.
4. Carb Clean – Over the years of people testing different chemicals. The one still in the lead is B-12 Chemtool. You’ll use this to soak the valves and let it soften up the carbon. Be sure you get the sprayable can.
*You must also have all the normal tools required to remove your intake manifold.
Blue painters tape
Big garbage bag or plastic tarp
Long hose to attach to the end of the blaster to be routed through the Shop Vac
1. Disassembly: The goal here is to get your Intake manifold off. This consists of removing the TMIC, (If you have it) your harness, and vacuum lines. A well written write-up on MSF to remove your intake manifold can be found here if you have not yet done this!
2. Mask off the Engine Bay: In order to prevent walnut from getting everywhere, a proper prep job is very important. Clean the face of the head, and around the runners well. They will be oily and blue tape will not stick well, unless it’s clean!Cut two trash bags so that they lay flat, and stick the tape to them. End result should like this! *Note that cylinder #2 is open and has been taped off.
3. Soak Your Valves: This is where the process actually starts! Spray down the valve with the B-12 Chemtool until all the build-up is covered. Let It sit for about 30-40 minutes. It may seem like a bit of time, but it does really help to make the process much easier.
4. Start Scraping: This is where your long picks will start to come in handy. With the carb clean still soaking on the valve, use the slightly angled pick to begin the process of removing the buildup. Once you think you have scraped enough off, use the air gun and the Shop-Vac to remove the fluid. Route the hose from the blaster through the vacuum hose as so: The air will blow out whatever is in there, and the vacuum will cleanly evacuate it from the runner.
5. Start Blasting:Fill up the blaster with a little funnel. Try to keep it over the box because this stuff likes to go everywhere. Once you have it filled you can proceed to the blasting. Start on the first runner of your choice. Make sure that the hose from the blaster sticks out enough to go a decent distance into the runner. Open the valve on the blaster with the switch on the side, and pull the trigger. Pulse it every couple seconds, as this allows time for the walnut to drain out, and gives your compressor time to keep up!
As you blast it, the compressed air forces it into the runner and then gets blown back into the suction of the vacuum. You will need to go back and forth between blasting and picking, as you run into stubborn bits that are giving you a hard time. You will need to go back and forth between blasting and picking, as you run into stubborn bits that are giving you a hard time.
6. Rinse and Scrub the Runners: Now you use the brake clean and a toothbrush. The runners by now will be coated in dust and some residue. Use the straw on the brake clean and thoroughly hit the runners. Use an old toothbrush or equivalent to scrub it. You may need to repeat this a couple times in order to get it nice and clean. Suck out the fluid with the Shop-Vac and air gun like you did in step #4. Your final result will definitely blow your mind! *Take extra time to ensure that you have no media left in the runners. Blow it out thoroughly.
7. Repeat for the valve that was taped off: Now that you have completed the ones that were shut, you need to tape those off, and unmask the runner that has the valves open. The easiest way to do this is to rotate the engine by hand. The Crank Pulley is a 21mm Bolt. Simply turn the engine to the right a little bit until the valves fully shut. Having a spotter tell you “when” is the easiest way. If the Buildup makes it hard to tell, then you can put a long screwdriver, or extension in the spark plug hole and watch it reach its peak at TDC. This will ensure the valves are fully shut. Soak the valve, scrape and blast, just like the previous valve.
8. Time to clean up: Remove your masking, and try to channel all the walnut into one area. Wad it all up and toss it. Keep the tape on the cylinder head until you are ready install the manifold. Used some compressed air to clean off anything that may have gotten media where it doesn’t belong.Reassemble, and start it up! Check for vacuum leaks or loose clamps. Watch your fuel trims and AFRs on your AP (if you have one) to make sure everything is normal.
Hope this will help you guys on your valve cleaning ventures, and you can always give us a call at 360-260-2675 if you get stuck! Till next time, Brett @ CS
