R.I.P Mazda RX Rotary

We received some sad news a few days ago about the much loved Rotary RX-7, RX-8 and other RX series. The official word according to the Mazda CEO Masamichi Kogai is that “we don’t have that kind of vehicle in our future product plan.”  when asked about a future RX. 

Honestly I’d love to pontificate about this more, but there isn’t much to say. It sounds like the final word from the current CEO. When pushed further he gave some reasoning that honestly makes perfect sense, “If you increase the number of segments, then the resources we can allocate to each will decline and that will prevent us from developing truly good products.” Also stated was the fact that “It’s difficult for us at present to further expand our lineup. The company is still in the process of improving its financial structure. We want to focus our limited resources on the Skyactiv products that we have today” 

Though this probably makes the most sense from a stability standpoint, it certainly doesn’t make us excited or want to say “Zoom-Zoom”. What happened to the Mazda passion? All that racing knowledge and development? Did they just give up on pushing the bar? Honestly, I don’t think so, I just think they are changing focus. The Rotary is off the board in the foreseeable future, but that doesn’t mean their current lineup won’t see some improvements…. after all, what about that Mazdaspeed 3 and MX-5?

Nonetheless, let us all take a moment of silence and mourn the passing of the RX series, for now.

2014 SCCA National Championship Runoffs

So, a few weeks back I attended the 2014 SCCA National Championship runoffs at Mazda Raceway Laguna Seca with aspirations of finishing on the podium in B-Spec with the CorkSport sponsored Mazda 2.

CorkSport Mazda 2

Day One:

The first day was a practice day in order to check out the car and review the changes we made, ensuring that everything was perfect for the three days of qualifying.  After the first test session, we made a few small changes and went back out for the afternoon session…

That’s where things got crazy.

The track was feeling greasy and the car was sliding around a bit, making corner 6 a handful since its taken flat out in a B-Spec car.  On the 7th lap the car drifted to the outside much faster than it had before so I steered into the drift and went off in the dirt. My plan was to ride it out and get back on the track towards the top of the hill.

Needless to say, things did not go as planned…


The video above is courtesy of a Spec Miata driver and friend at the track Steven Powers who (being directly behind me) got front row seats to witness the whole thing.

Rather than riding it out of the dirt, the front corner of the Mazda 2 made direct contact with a concrete wall… sideways (which  data showed being at 30mph). After playing 20 questions with the safety crew and getting the car loaded up, I was dropped off in my pit to evaluate the damage and make a plan on what to do next.  We got the car disassembled with help of fellow racers, slowly realizing just how bent up the car really was.  Besides the sheet metal, we had punched several holes in the engine block, broke a wheel, bent the right side control arm and front sub frame.

It took 2 hours to take the car from a crunched mess to the picture below.


The Aftermath

Day Two:

I chose to sleep on the decision to either rebuild or scrap the whole weekend race.  The next morning, with an optimistic attitude, we took inventory and made the choice to rebuild the car at the track. Mazdaspeed Motorsports lent a major hand as we started chasing down the parts we would need to replace, while I was hitting the phones looking for a body shop with an empty frame machine so we could get started on the car ASAP.  8 calls later, we had our shop and loaded the car up on a flatbed in order to get the repairs going for straightening the car and getting it ready for a frame rail and shock tower.

More Aftermath

Spectrum Auto Collision was a great help with the overall repair of the car. They got right on the job and loaded the car up on to the frame machine while their awesome technician started straightening the drives side rail. Arrangements were made to have the replacement frame parts arrive to the shop for the following day so they could continue the repairs non-stop, getting the car back together for Thursday’s qualifying session.

Day Three and Four:

Due to a mishap with UPS, we were out one critical part needed to not only start work that Wednesday morning but also have it completed by that afternoon. This complication pushed back the plan that included having the car assembled in time to post a qualifying time.  After a discussion with the race officials, they agreed to let me start at the back of the B-Spec field allowing me to race despite not having a qualifying time. Which was awesome of them.

That Thursday evening, my trusty friend was delivered right back to the track so that we could start the re-assembly process. With the help of my crew, we rebuilt the engine, reinstalled the whole front suspension and sheet metal, and reinstalled the rebuilt motor within two days.

Day Five:

Saturday evening, we fired up the car to make sure it would be ready to go for the race.  After a drive around the paddock, the car was feeling good and ready to race on Sunday.


Lucky for us, the B-Spec/T-4 race was the first event on Sunday, meaning the track would be in its best condition.

Since I was at the back of the field, I snagged an opportunity to pass up the stacked up cars on the inside of corner 2 and get passed 2 cars in the first lap. Several laps later I was able to get around one of the HPD Honda fits, putting me in 8th place. The leading Chevy sonic was brought to a stop due to a check engine light, moving him from 1st place to last place and me to 7th. During the race, the Mazda 2 felt really loose (the back of the car was sliding around) and like the tires were wearing out quickly.  This is not expected due to the brand new tires we just had put on the car for the race. BFGoodrich tires always hold up extremely well to the abuse of B-Spec cars.  I reported it to the crew over the radio and I got back an acknowledgement.

CorkSport Racing Accident

If you look at the picture above you can see smoke rolling out of the front wheel. 


At the end of the race (back in the pits) I saw the driver’s side of the car was coated in Redline MTL transmission fluid which had also been coating the front and rear wheels causing that loose feeling I was getting.

Imagine driving on and off ice whipping through corners at the fastest speed you can go. That is exactly how crazy the race felt driving with the transmission fluid everywhere.

Later I found out that the crew had actually seen the smoke but decided to keep quiet about it so as not to alarm me and keeping me from changing my driving style (which had already been working). I am incredibly thankful they made that call, because it would have changed my driving and possibly caused more problems.

The final result was 7th place, which doesn’t give any trophies from the SCCA but I got something even better from Mazdaspeed.  I was gifted a copy of the book Never Stop Challenging, which chronicles Mazda’s path to winning Le Mans and overcoming all of the challenges they went through.  I was told by a good friend at the track (who has experience in amateur and professional racing) that he had not seen a car with as much damage as we had, rebuilt and make it back onto the track before.

Thank you so much to CorkSport, Monarch Inspections (for the season long logistics support), Mazda Motorsports Crew, John Doonan, Mike Allen, Scott Kaluza, David Cook, and Dean Case who were at the track for the parts sourcing and tech help and the best trophy a Mazda racer could get.

Big thanks to my Dad (aka the crew), Joey Jordan Motorsports (for the help rebuilding the motor and getting the alignment straight), James Wilson and Black Armor Helmets (for driving out to race his 2 from Texas), Brad Green and his crew (for help getting the car taken apart), Steven Powers (for the video) as well as all of the B-Spec racers who I got to compete against all season long.

Last but not least (in any way), I would like to say thank you to my wife Jessica and two daughters for being understanding of my pursuit in racing.

Let’s keep this simple. You want the juice, the news, the lowdown, the gossip on everything Mazda….

Well good news! We have some great rumors for you here, and a little dose of truth. Let’s take a dive.

Mazda CX-3

First up, the Mazda CX-3. This lightweight, compact crossover should be going toe to toe with the Nissan Juke and other compact SUVs. Rumor has it that it should be powered by the 2.0L SkyActiv, likely the same one in the Mazda3. To be clear, this little gem won’t have to be waited on for very long. The CX-3 is set to release next spring, and better yet, debuting at the LA Auto Show in less than a month. Yep, we should have our hands on this guy sooner than later!



2016 Mazdaspeed

Then again, you probably didn’t come here for news on a compact crossover that has killer gas mileage, room, and the practicality of a sedan/suv/compact car blended into one. You’re probably here for this: the 2016 Mazdaspeed. Though there still aren’t any confirmed dates or models, we keep getting “insider rumors”. According to Motortrend and their “insider”:

“What gets added to the lineup in addition to those cars is the interesting bit… the company plans to focus heavily on development of niche products, or in other words, special editions.” 

Special editions? Sounds like Mazdaspeeds to me! Any other “special editions” you can think of? Nope. I’m sold. Motortrend also states that a 2016 Mazda 6 Coupe will be released (see their rendering below).





As exciting as a coupe is, we tend to be bigger fans of Hatchbacks, specifically hatchback Mazdaspeed 3′s. So what does Motortrend think we have in store?

Another important niche model is also planned for 2016: the much-anticipated Mazdaspeed3. This hot hatch will employ a 2.5-liter Skyactiv G turbocharged gasoline engine pumping out more than 300 hp and incorporating a new lightweight all-wheel drive system. To add even more spice to the company’s lineup, we can also expect to see Mazdaspeed versions of the Mazda2 and Mazda6.”

Wait, what? Mazdaspeed 3, Mazdaspeed 2, and Mazdaspeed 6? I’m all ears. 

But will it happen? Looking at Mazda’s past, they certainly have touched most of their smaller cars with the hand of Mazdaspeed. Protege, MX-5, the 3 and the 6 all have been turboed and “Mazdaspeedified” before, so doing the 3 and 6 again is a no brainer…

But the 2? I think it’s highly possible. Most likely, the Mazda MX-5 will get a Mazdaspeed version before any of the other cars, and then they’ll dump the same engine in the new Mazda 2. Why not?

Whatever Mazda decides to do, we’re pumped. Looking at the models they have cranked out in the past 2 years have been impressive and we are very excited for more models and specifically their “niche…special editions”.

Dear Car Guy,

I’ve been thinking about you lately. About how much you invest in your car, your community, and yourself. I wanted to point out some of the best ways you’ve grown, so here are 10 of them.

1. You spend your time researching the best parts, not just the cheapest.

There was a time, in your beginning stages of modding, that you would go for the cheapestand not necessarily the most reliable. Over time being cheap bit you in the butt, and now you take your time and put more research into parts before you make a decision for your baby…I mean, car.

2. You can’t stand loud exhaust drone on the highway.dear car guy

What used to be music to your ear – that amazing sound or missing muffler – is now an annoyance to you on your drive. You like the throaty growl of a deep exhaust, in replacement of the high pitched overpowering scream of “yeah that sure is loud, but is it healthy?” of days gone by. Yes, your exhaust could be considered loud, but when the cops are called by your neighbors’ complaints, they laugh it off and say, “That’s not loud, that’s just sexy”.

3. You are spending more money on parts, than payments.upd2

You’ve come closer to paying off your baby, and now are putting money into making her everything that you have always dreamed for her to be. Your hard earned cash goes towards the things you want, not just back to the bank. You feel free, mostly because your warranty is over at this point anyway, to do whatever your heart desires to your car (within the realm of your preferred tastes of course), and could care less what others have to say about your taste in mods.

4. You find yourself concerned with power and handling over the latest looks.

It’s been awhile since you’ve added any new stickers, and you’re a bit more picky about who you rep while you drive anyway. You’ve scraped off and replaced those that were placed on your beloved ride without much thought, and actually calculate how much ‘sponsorship’ you give on your vehicle. When it comes to form and function, you prefer to make sure that your ride handles appropriately so you can back up your words first, before throwing cash at the outside.

5. You max out the current potential of your current mods before adding others.

It’s pretty easy to continue to purchase new mods, but when you do, you make sure that you’re doing everything to get the full potential out of each and every enhancement. Instead of installing and moving onto the next part, you log for weeks making sure you’re getting the max of every single installation. You enjoy the time under your car, but you won’t do it if it’s not worth it.

6. You start investing in your driving skills, instead of changing your car.mazda meme

Days spent on the track, or long winding roads are where it’s at for you these days. You know that spending time honing in your personal handling abilities is just as important as making sure you have the right bars, braces, and parts in place in order to drive appropriately. Be it auto-x or straight track you keep yourself as tuned in as you do your vehicle.

7. You’re more aware of the miles per gallon on your daily driver, which is why you now own a ‘daily driver’ and a ‘race car’.

Yes, it’s been awesome growing up and spending WAY too much money to make the fastest car around, but these days you keep that one in the garage, and settle for a daily commute in something a little more reasonable on the wallet. It’s an ego check, but a justifiable one, for when you’re driving whichever gas-save it is, you’re thinking of how much cash you’re saving to spend on your next mod.

8. You know the true meaning of a Car Club, and aren’t afraid to pitch in or ask for support.

You understand that as much as you love your car, it’s not just about her. It’s about the people you connect with and spend time with at the shows, meets and installs. Those that you talk shop with, enjoy life with and find yourself missing after only a day away from the latest meet. You look forward all year to summer time and fun road trips, flights, and weekends spent with people you wouldn’t even know if it weren’t for your car.

9. You know that it’s not just about the cars.

You get that it’s your connection to a world of people who are genuine, caring, and supportive. People who will jump in at a moment’s notice to put together a donation thread for your sick kid, hurt puppy, or after an intense accident. That no matter where you are if your car breaks down on a road trip, there will be someone on their way shortly to help you sort through this mess, whether you’ve met them before or not.

10. You know when to be content.mazdaspeed shifter

You’ve hit the mark, and leveled off. You love your car and all the time spent underneath it making it exactly what you want. So you slow down. You can honestly say that you are content with your car, you don’t “need” that part, but there is nothing wrong if you want it. The latest and greatest will be the dashboard hula girl mod for a week or two, or the “oh crap the kids spilled all over the back and now it’s time to detail the car completely”. You become the ‘go-to guy’ for your car friends on install day, and now you go for the food and fun, and find yourself helping just for kicks.

Sit back and enjoy, Car Guy. You’ve earned it.

Until Next time, stay safe, stay happy, and stay fast.

One last note from our President, Rich, on submissions:

“No Scubs!”


Today we are launching an all-new CorkSport, a version we’re calling CorkSport 3.0. Before I get into this, let me give you some insight into our journey thus far.

CorkSport 1.0

CorkSport 1.0, when we were exclusively a reseller (1998).

Derrick and I started CS in 1998. Back then we were just two dudes (yeah, almost Lebowski dudes). We had no clue what we were getting ourselves into. CS 1.0 was crude in hindsight, but we at least had the one ingredient that mattered most: a passion for Mazda performance. We were exclusively a reseller at first. We sold products from companies like Mazdaspeed, Mazda of Japan and FEED. Check out our original logo (right) when we first launched.

CS 2.0 started when we decided to develop our own brand of parts. This started in 2002 with exhaust systems.


CorkSport 2.0

CorkSport 2.0, when we ventured into creating our own exhaust systems (2004).


It quickly grew from exhausts, to intakes, to everything we do today. We’ve changed our logo twice since the beginning. You can see our last and current logo below.

CorkSport 3.0, the industry leader in Mazda performance.

CorkSport 3.0, the industry leader in Mazda performance.

CS 3.0 starts today.

Why? We’ve grown up. Not in the sense that you wouldn’t find us going a hunski on the 5, but in the sense that our business has grown significantly, at least by comparison to our meager beginnings. Many families now depend on our business and many thousands of our customers depend on the products we develop. We’ve grown up in the sense that we’ve learned enough to know what it means to be excellent. We know what we are capable of, and we know you want excellence too. We are prepared to deliver excellence as we never have before.

There are components of the new CorkSport that you will be able to see, and there are components you will not be able to see. As for what you can see, you’ll notice a new version of our logo across all channels (our website, Facebook, Instagram, Twitter and Google+). We have a brand new website. The homepage has been totally overhauled to give you more of what you’ve told us you want. Our product pages have been revamped too, including better content and more logical organization. You can see what we mean in our re-release of the CorkSport Exhaust for Mazdaspeed 3 (honestly, there is minimal change to this listing, but you can understand how the video and images are improved). This is typical of what you’ll see from the dozens of products we are set to release in the months ahead.

Raising the Bar on Our Product Development Process

Much work went into what you can see, but even more went into what you cannot. We have totally overhauled our product development process. Our new process more robustly:

• Applies FMEA techniques to ensure a longer, issue-free lifetime for our products.
• Applies quality controls. We are demanding more from our partners than ever before, and they are responding.
• Applies quality assurance. Both externally and internally we’ve expanded our quality assurance efforts. We’ve even got a CMM (coordinate-measuring machine) in the pipeline to further expand our QA efforts.
• Collects the data you care about during the development process so that it makes it to the public (dyno testing, AFR, fuel trims, boost levels, fuel pressure, etc).
• Includes modeling and 3D printing to reduce development time and improve quality.


Exceptional Service

You hate back orders. So this is our goal: eliminate misses and near-misses. We want awesome, all the time. So it’s also worth mentioning that we’ve totally overhauled our supply chain management. Back orders are now 75% lower than they used to be. 

Further, you will receive a consistent experience no matter which CS part you buy. You know it, and we know it. We’ve tried to hit certain price points to make our products available to more customers, but we simply will not compromise quality to do so. To some customers CS means great value. To other customers CS means uncompromised quality at a fair price. Moving forward, you won’t see new products where we need to educate customers about what quality costs. If we have to have that discussion, we will avoid making the part in the first place. We still seek extremely high value but the bar has been raised for what CorkSport quality means.

We thank you for your support for the past (almost) 17 years! You’ve allowed us to grow our business large enough that it fills an entire city block. We are, by far, the #1 source of new products in Mazda Performance.

We will continue to return the love by supporting only the Mazda brand. We are Mazda performance to our core.

This post is part 2 of a 2-part series on the importance of injector seals. If you’re just now discovering this post, be sure to tune in to part 1 before continuing here.


Like the title says, you need injector seals for your MZR! Here’s why.

When Mazda designs a part, they design it with the “typical” customer and OEM power in mind – not the power hungry, boost craving driver.  Yeah, I’m talking about you and you know it – and we have just the thing to keep you and your MZR in check.  As you add more fuel and more boost, the weakest link is eventually going to give. That link is the OEM injector seals.

Three Reasons You Need Injector Seals For Your Mazdaspeed

  1. Reliability is sacrificed using the OEM seals.
  2. Leaking seals causes loss of power.
  3. Inconsistent performance is caused by leaks.

So, if you are just tuning in to our blog, then shame on you, go read part one like everyone else! With that, let’s dive into the design of the seal and how it works.

We put 500 hard miles on the Speed3 and here are the results.  500 miles may not sound like a lot, but the company owned MS3 does not live the normal life. It spends most of its time on the dyno testing new products pull after pull, may have hit 35psi, and when it does hit the streets, it’s driven by an employee searching for the governor speed.  I think we can all agree that the 500 miles was a fair amount of abuse to put the injector seals. Plus, other sets of seals have been running in alpha testers vehicles for thousands of miles without issue.

Now that we have that covered, let’s talk a bit more about the design of the seal and how it works.


It’s no longer just a washer with one sealing surface – it’s a cup. So it seals in the OEM location AND along the side of the cup. The secret is in the design (which is all thanks to @Tokay444 from MazdaSpeedForums).  The lip at the bottom of the cup is flared just a bit so that it crushes down tight against the cylinder head, and as it crushes down it also crushes outward, pushing against the wall of the port much like an O-ring. If you are having trouble visualizing the flared lip crushing outward then check out the image below. Time to get technical!


Looking at this side view of the seal, you can clearly see that the flared lip is extended further outward than the side of the seal. (Please note that in this FEA, or Finite Element Analysis, the deformation scale factor is 6.5:1, i.e. highly exaggerated). This design is what separates the CorkSport seal from any other seals on the market today. In the FEA the seal is subjected to 3300lbf in the direction of the arrows; 3300lbf is the approximate clamping force of an M8x1.25 torqued to 18ft-lb. The areas in red indicate a displacement of 0.0057 inches, which is just enough to begin yielding (permanently bending) the beryllium copper material. After the 500 miles of use, we had the four seals precision measured using a CMM (Coordinate Measuring Machine). On average, the seals yielded 0.0015 inches confirming our FEA.

Still following?

So what does this mean to you? When you torque down the fuel injector bolt and clamp you are applying approximately 3300lbf to the injector seal. This crushes the seal downward pushing the flared lip outward into the wall for ultimate sealing strength; and we have all the data to prove it! The CorkSport seal works flawlessly, but because of the design they are not reusable like any other crush seal.

So, now that we are done with all the technical stuff let’s take a look at the used seals. First, I would like to remind you what the injector looked like with the OEM crush washer and only 4000 miles.


Extremely dirty with an excessive amount of combustion gases blowing by the OEM injector seal. This makes for a very unhappy MZR. Second, in the images you are about to see, the seals have not been cleaned in any way, shape, or form. I pulled these out of the car and immediately took the pictures. Prepare to be WOW’d; I know I was…




Besides the clean injector body, there is a more subtle detail that needs to be pointed out. If you look at the very edge of the flared lip on the seal you will notice that the black soot does not go all the way to the edge. This further confirms that the seals are working the way Brock (@Tokay444 on MSF) had envisioned them and we can also see this “clean ring” in the cylinder head below.


In the image below you will notice that the seal is dirty on the inside, but that’s okay – that happens by design. The “shelf” that you see midway up on the inside of the seal seals against the injector body instead of in the OEM location further down around the injector nozzle. This change in sealing location allows the flared edge to deflect how it needs.


If I haven’t convinced you yet why you need injector seals for your Speed3 then you’re hopeless…you should go get a Civic or something else that’s slow…


Between our results and the reviews given to us from our alpha testers we have great confidence in the seals and you should too! Keep an eye out for these to be released very soon! Zoom – Zoom! -Barett, CS Engineering



The 2016 Miata is Finally Here!

There is no official word on the engine, weight, or other specs yet, so we will just leave these photos here.
