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.

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.

A DIY Mazda Maintenance Infographic for You

Guys, we know you know how to take care of your Mazda.

If you’re mechanical enough to mod your baby out, you’ve probably been changing oil filters since you were yea high *hovers hand about two inches off the ground*

That said, we also know there are a lot of noobs just getting into Mazda maintenance, and that even the best drivers among us don’t always know how much it pays off to take care of your Mazda yourself.

So, to illustrate the point (and a helluva lot of statistics), we created this handy Mazda maintenance infographic. In the small chance you’re not already doing these Mazda fixes yourself, you should be; and in the big chance that you are a DIY Mazda guy, here’s a nice graphic to share with all your new Mazda driver friends.

So, behold, the DIY Mazda maintenance you better be doing if you consider yourself a car guy:

We know you know DIY Mazda maintenance, but a nice, clean Mazda infographic never hurt anyone, right?




The Good, the Better, and the Best Upgrades for Your Mazdaspeed

The good, better, and best upgrades for your Mazda.

Think back to the first day you bought your Mazdaspeed. I’m sure for most people, it’s a day you’ll never forget. What was your first thought about the car? I know my first thought was, “What aftermarket parts can I install on my speed?” Let’s be honest, when it comes to the boost bug, the bug always gets you. One can’t simply own a Mazdaspeed and not modify it. It becomes an addiction, a way of life.  If you’re like most Mazdaspeed owners, you can’t settle. You want to make sure you’re getting the best parts possible. So, where do you start when it comes to adding modifications to your speed? There are many ways to increase power with the Mazdaspeed platform, but finding the correct path can sometimes be a challenge!

Once you’ve bought your Mazdaspeed and you’re looking for the correct path to take, there are some specific modifiers you want to make sure you do first. If you have a goal of making your speed a fully bolted machine, the first thing you want to do is upgrade the fuel pump internals.



Everyone wants more boost, and with more boost comes the demand for added fuel. With that demand, you need to make sure your fuel pump pressure doesn’t drop below 1600psi. Some people can get away with doing big power modifiers without upgrading the fuel pump internals, but it’s highly recommended not to push your luck. $349.99 to upgrade your fuel pump internals or $5k for a new motor because your fuel pressure dropped below 1600psi at WOT. Take your pick! The CorkSport Max Flow Fuel Pump Internals Kit is the safety net you need on your builds list. This kit adds up to 50% more fuel, which is perfect for people looking to get their speed fully bolted. Once you’ve installed the fuel pump internals, you’ll be able to safely reach horsepower numbers of around 350-380whp without any other modifications to the fueling system.

Now that you’ve successfully upgraded your fuel system, you’re ready to start making some power. One thing to keep in mind when doing modifications, is that the ECU needs to recognize your added modifiers such as a FMIC, down pipe, full intake, or any other performance part that will increase hp/tq. There are a few ways you can do this, but using an AccessPort is the most popular tool used on the Mazdaspeed platform.


Not only does the AccessPort allow someone to customize a tune based on modifications made, it’s also a great tool for monitoring different kinds of parameters as well as reading and clearing check engine light codes. By spending $649.99, you’re able to fully customize a tune for your car and make sure the car is running safely. Whether you want to have a fun street car or a full-out track car, the AccessPort is a must for any speed owner looking to add power modifiers.

Now that you have the proper fueling, and an AccessPort to make tuning easy, you can do anything you want to your speed. With that being said, my next modification recommendation would be a full intake for your vehicle.


Besides the fuel pump, the intake has one of the biggest restrictions for the turbo. Not only are there too many hoses running the stock intake, the turbo inlet pipe is designed flat like a pancake which chokes the turbo under load. By installing our stage II SRI, you remove the hoses, air box, and pancake turbo inlet pipe making the overall efficiency of the turbo much better. You may also see an increase in boost psi which is something we’re always trying to increase. Our intake is $249.99, which is a great price considering everything is custom made for the speed platform, and you get the best possible bolt on parts. After you’ve purchased and installed the intake, you will notice an overall increase in power and sound. A must-have for someone looking to start with a great power modifier.

These recommended first mods would be considered the good, better, and best modifications to start with if you’re ready to start modifying your Mazdaspeed. With fueling no longer an issue, having a way to tune your car, and allowing the turbo to breathe, you will definitely start to notice a gain in power, sound, and overall love for your Mazdaspeed!

Limited Slip Blog Reminds Us: The Gen 2 MS3 Is Incredible

As we eagerly await more news about the 2017 Mazdaspeed 3, it’s easy to become distracted by a wish list of features, making us forget about the Gen 1 and 2 marvels sitting in our garages.

We’ve hoped there would be a new Mazdaspeed 3 sooner than now, but the compensation of waiting is owning and driving Gen 2 (or Genjuan) Mazdaspeeds every day. Sure, we’re a little biased, but there’s a reason our lives are centered around Mazda performance enhancement. Maybe we’re just feeling nostalgic because it’s #ThrowbackThursday, but whatever the case, the Limited Slip Blog’s 2013 review of the last Mazdaspeed 3 reminds us: Even a few years old, these cars remain incredible.

Christopher Little takes a mean shot of the MS3.

We stumbled across this blog entry after finding that killer shot above, taken by cofounder Christopher Little. If it wasn’t clear from the entries that cover just about every car under the sun, it’s obvious just glancing at their photography that these guys have a passion for vehicles, something any self-respecting Mazdahead shares.

Gen 2 Mazdaspeed 3 from Limited Slip Blog

Chris had some issues with the interior—but noted the Gen 2 Mazdaspeed 3 had the best visibility of any hot hatch he’d driven. His description of the first time he actually drove the car probably sounds like what a lot of us experienced when we first got behind the wheel of a ‘speed. The word “intoxicating” stands out, which shouldn’t surprise anyone who understands Mazda power. The Mazdaspeed 3 makes it just about impossible to drive without experiencing some raw joy, which Chris did. We get it; that’s why we devote our lives to Mazda performance, to bring even more power out of these beauties.

The Mazdaspeed 3 has always been a stunning and, yeah, intoxicating ride. It’s been great for almost a decade, and with the new generation coming out soon, we don’t expect that legacy to change.
