We want YOU to help us design the next CorkSport Branded Ride!

As if it wasn’t obvious, we have a plethora of vehicles to work with around here. True to fashion of course, we at CorkSport have gone and done it again: We went and filled some of the last remaining shop space with ANOTHER CAR.

Not just any car. Say “Hello” to our newest addition: 2018 Mazda 3 Hatchback, touring 2.5L SKYACTIVE-G. Equipped with an automatic transmission and some of the nicer creature comforts.

We love the sparkle of the Eternal Blue Mica and of course her 18” gunmetal dancing shoes. However, as with all things good and standard in the world, we couldn’t help but think that the potential for upgrading is endless.

Do we strip it and go full race car? Perhaps something crazy and AWD swap of sorts? Or maybe we take it way out of left field and go rally-style with it?

With the opportunities being endless, it was starting to make our heads hurt, so we decided to take a step back and start with the basics. We asked ourselves:

“What would our average customer who just picked this car up do?”

And that is exactly what we are doing.

If you guys are anything like us, then you have several hobbies that extend beyond just cars. Some of our team’s personal favorite other hobbies include hiking, camping, traveling, water sports, chilling at the beach, and has recently included obstacle course racing. With all these interests taking up different aspects of our time, we would need a ride that can accommodate our lifestyle. While it would be awesome to have a 6-second drag car, we’d probably have to lose some creature comforts or find a pot of gold to cover the cost, and that’s just not what the average Mazda enthusiast is about.

This project, like we said, is for YOU. And if it’s for you, then we need your help in putting it together.

This car, or as we are designating it: “Project CBR” (CorkSport branded ride), will be built by the people for the people.

We are going to take you with us on the full journey of this car; from the basic mods to the full on weekend task. From the daily driver to the long road hauler. From the car wash to the full service details. We are going to show you everything and anything on this car.

And through the whole process, everything is going to be built with your help.

Over the next several months as we put some miles on our test mule, we will want your guys’ feedback.

  • Do we put springs and shocks on it or full coilovers?
  • What type of wheels should we get?
  • Tint the windows, wrap it, get rid of the chrome?
  • The list goes on!

Every couple of weeks, we will keep you updated on where the car stands and what you think we should do next.

We will create a section on the CorkSport site so you can follow along, ask questions, provide suggestions, and fully immerse yourself into the car. Ever so often, we will also host a poll and you guys will vote on what happens next!

Think reverse sponsored: Instead of CorkSport’s name being the only one on this ride, we will be giving Sponsorship Cred to the Mazda Enthusiasts who give us the ideas for our mods. (first come, first credits).

We’ll put YOUR NAME on the CorkSport Branded Ride.

If you have a Dream Mod, and We pull it off on the CBR, you’ll get the credits… Remember: The CBR is By the People, For the People!

Stay Tuned, we’ll need your feedback soon!


4 inch Intake and a Clean Engine Bay? The CorkSport 51R Battery Box & ECU Relocation is NO Compromise

CorkSport is proud to announce the new ECU Relocation Battery Box designed for the 51R battery and 4” intake systems.

We love the clean and simple look of the CorkSport full size battery box and we know you do also, so our goal here was to bring that same level of awesomeness to all the big power guys and gals running 4” intakes and 51R batteries.

We knew we couldn’t compromise on the fit and finish you’ve grown to love; and this new battery box doesn’t disappoint.

The greatest challenge came in the form of locating the ECU inside the box; as that is the whole point of the CorkSport battery boxes. With a bit of massaging and adjusting, we innovated a sleek solution for the ECU placement without compromising the style and fitment of the battery box.

In the original CorkSport battery box the ECU was located on the front panel. This packaged well with the full size battery and made access easy, but in order to increase the clearance for a 4” intake system we had to reduce the width of the battery box as much as possible. This required us to rethink the location of the ECU and the overall design of the battery box to accommodate it. Check out the computer drafted model below.

Moving the ECU to the side provided ample clearance for a 4” intake system and retained the standard battery location. The front of the battery box had to be extended out a bit, but this also gave us a chance to keep the wiring harness inside the box to maintain the high level fit and finish. To finish off the installation, the battery is retained with M6 studs fastened into the battery box and a 0.120” anodized aluminum bracket.

Overall the new 51R ECU Relocation Battery Box hit all the marks for fit, finish, and performance.


If you’re looking to downsize your battery, upsize your intake system, or are just plain tired of looking at all those unsightly wires then let the CorkSport 51R ECU Relocation Battery Box be the answer to your goal.

Turbo Kit in Development for 2014+ Mazda 3 & 2013+ Mazda 6

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.

©Car & Driver

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.

It has been a wild and crazy ride over the past nearly 20 years. We started as enthusiasts, just like you. Engine swaps, tuning, aero kits, suspension, we got down and did it all.

We wanted parts for our cars, and we couldn’t find them, so we started a company to track them down (enter CorkSport brand, instead of just two guys in a garage). We convinced venerable companies like Mazdaspeed and Autoexe to sell us their parts. We figured out how to get parts from Japan to the States. It wasn’t always easy. For many, many years we never made any money, we had to balance ‘real jobs’ and our dreams just like many of you. We eventually scraped out a living hustling Mazda parts.

We couldn’t get everything we wanted. And frankly, some parts from Japan were just too expensive, so we started making our own (imagine that custom fabrication in a larger scale). We filled out our catalog with CorkSport brand parts. Now, the only thing we sell that is not a CorkSport part is the AccessPort. How far we’ve come!

It’s been a non-stop investment in the Mazda community for 20 years. We’ve done our best to support the platform like no other company. We’ve taken most of our profits and used them to make more Mazda parts. Of course, there has been a bit of racing in there too.

Mazda has not been doing anyone in the aftermarket any favors. Sure, they make cars with the suspension tuned a bit more sporty than your average Toyota, and the engines have some pep, but they are not selling cars for enthusiasts (except the Mx5). They have not sold another car for enthusiasts since 2014! This feels a lot like Mazda of the 90’s but with better marketing.

Look around at the aftermarket, and you see most of our competitors were already spreading their attention across multiple platforms or have since added platforms like Ford. It’s important for us to stay focused on the Mazda platform. We know that commitment is important to most of you. But how do we grow in a stagnant market?

We are taking everything we’ve learned and going after a new market, with a new company. Before we reveal what we are up to, I’d like to give a little perspective. TV shows like Shark Tank and The Profit have pulled back the curtains on the inner workings of business. People better understand that companies need to grow to thrive. Companies need to make money to stay in business. And I believe people also understand that business owners can have multiple businesses and still have a dedicated team hell-bent on kicking ass in their market.

Imagine going to your favorite food stop. For us, it might be Blue Star Donuts in Portland.  

We love these donuts. Then you find out the owner has opened a ramen shop (this really happened, check out Boxer Ramen). What?! What’s going to happen to my donuts? And what the heck do donuts have to do with ramen? Well, it turns out the owner kicks ass at running these companies and can make great donuts AND great ramen. Who knew?

Each restaurant is different, but they also have a lot in common. In fact, a restaurant has a lot in common with a Mazda performance shop. It all comes down to Product, Process, People (thanks, Marcus Lemonis).

I’m not saying we are a restaurant. The point I’m trying to make is that the owners of a Mazda performance shop can open another shop and it’ll be ok. It might even be a good thing; I’ll explain that later.

We have a dedicated team that comes to work every day to serve the Mazda aftermarket. That won’t change. Our new company will be a separate business with its own team, goals, and eventually building. In fact, most of our team is not even involved in the new business right now. We are going to do everything possible to make sure CorkSport doesn’t lose focus on what’s most important to it, Mazda Performance!

OK, so what is this other business? It’s called 27Won (pronounced Two-Seven-One) Performance.

Check it out here: www.27won.com. Maybe you can help us out by spreading the word!

We could have used our CorkSport name, but to us, CorkSport is and always will be Mazda Performance. We’d rather go through the extra work of setting up and running another company than take the chance we lose focus on Mazda performance.

We are positioning the new company at the very top of its market. We are investing heavily in product and process at a level beyond what we’ve been capable of in the past.

You are going to see big improvements in the CorkSport brand soon. We are making all sorts of adjustments to our marketing team. We’ll have new gear, more interesting blogs and social media content. You’ll see further into our product development process. And last, but certainly not least, we have some exciting new products to announce very soon.

Stay tuned!
