Safely Upgrade Your Mazdaspeed Turbo

It doesn’t take long for those building power to use up the stock Mazdaspeed K04 turbo. They are prone to fail, especially when you start shoving that extra air through it. A common question is, “My Mazdaspeed is smoking, is my turbo bad?”

First things first. There is a BIG difference between replacing a bad turbo and upgrading Mazdaspeed K04 to a more efficient one for more power. If you want to replace it, go with OEM and just plug and play, you’re good to go, wash your hands, and get on with your life. This will have your car up and running pretty quickly. However, your maximum power output will be limited and you will eventually have the same problem – the Mazdaspeed KO4 turbo will fail.

If you are saying to yourself, “It’s time to upgrade…I NEED more power in my life!” Then this blog is for you. Below, we lay out the basics needed to successfully install a CorkSport Mazdaspeed Turbo, highlighting the required supporting modifications to keep your Mazdaspeed safe. As a bonus, we keep our installation instructions on each of our product pages, so you can preview how easy the installation will be for your experience level.

Mazdaspeed Turbo Upgrade for the K04 BNR

Here it is, the list is comprised of the BARE essentials to run the 18G CorkSport turbo.

HPFP INTERNALS

Giving you 50% more efficiency with your fueling system, as well as, a strong base to build power for your Mazdaspeed. The CorkSport Max Flow Fuel Pump Internals are built to directly replace your stock fuel pump internals and perform with immediate improvements.

ACCESSPORT (or VERSATUNE if you have a CX-7)

The Cobb Accessport will give you the basis for tuning, and since this is required with the CorkSport turbo – you’ll want to make sure you have this in hand and ready for when you install your turbo.

These are the basic foundations of our Mazdaspeeds, without these two items you cannot operate your Mazda after installing an upgraded turbo.  You will need your Mazdaspeed tuned, and your tuner is going to say the same thing.

That’s it, that’s all you need to run the CorkSport Mazdaspeed turbo safely. With this proper foundation, you can put yourself in a position for efficiency, or more power.

CorkSport Upgraded 3.5” Intake

The CorkSport turbo is rated for up to 450WHP with the right set up. Unless you are going for the MOON and shooting for over 700WHP a 3.5” intake will be more than sufficient for this turbo. Giving you some extra airflow to increase your power range, and harness what your Mazdaspeed3 is capable of. Note: Will require additional tuning!

Mazdaspeed 3 Turbo Back Exhaust

CorkSport Mazdaspeed Downpipe

Doesn’t matter if you go with a high-flow catalyst or opt-in for one without, the choice is yours. However, if you want to utilize its flow you are going to have to upgrade to a bigger diameter. Our 80mm one does really well, plus it sounds GREAT.  Note: Will require additional tuning!

The CorkSport Cat Back Exhaust System gives your new 2016 Miata the power it needs without the annoying drone.

CorkSport Cat-Back Exhaust

It’s no secret that car engines are just big air pumps, the faster you can shove air into the engine and how fast you can expel it efficiently is what it takes to make more power. No need to run the stock 63.5mm exhaust when you can run our 80mm (like to wake up the neighbors every morning, go with our non-resonated, you can’t beat the cold start)

Top Mount intercooler or the Mazdaspeed

CorkSport Top Mount Intercooler

If your power goal is 450whp or less you can get away with just upgrading your TMIC and be on your way and they look great in your engine bay.  Note: Will require additional tuning!

If you have the 2nd gen you can really utilize that hood scoop from the factory.  Not only that but you can even see a noticeable performance gain with our larger hood scoop and a TMIC set up.

When it comes to your Mazdaspeed we know you want to create safe power and harness the true potential of your ride. Be sure to build upon the proper foundation and head in the right direction for your build.

Intake Valve Cleaning – A Dirty Job Made Easy

Introducing the CorkSport Intake Valve Cleaning Kit. While designed specifically for the DISI MZR engine found in the Mazdaspeed 3, 6, and Mazda CX-7 turbo. Our kit is versatile enough to be used in a variety of direct injected (DI) applications and alleviates many of the pain points associated with cleaning your intake valves. For an explanation on why DI engines need their valves cleaned, check out our blog on cleaning Mazdaspeed intake valves. Read on as the CorkSport Valve Cleaning Kit could make your next maintenance job much easier.

Despite its interesting appearance the CorkSport Valve Cleaning tool was carefully designed for ease of use. Starting at the large end, the cone shape was selected to accommodate a wide variety of vacuum hose sizes (1.50-2.5- inch OD) – it even works with the oblong-shaped hose we have in the CS shop! A clamp is included to keep the tool secure on the vacuum. Due to the slightly flexible nature of multi-layer silicone, clamping the hose creates a seal useful to get great suction from the vacuum.

To provide the best fit for both the large and small intake ports of the DISI MZR, the opposite end of the valve cleaning tool also is flared. When in use, this flare compresses slightly, making for another great seal. This keeps the cleaning chemicals, media, and any carbon deposits from getting all over you and your engine bay.

Last but not least is the small diameter offshoot on the side of the CorkSport Intake Valve Cleaning Tool. This is the port for a media blaster that helps make quick work of dirty valves. It is positioned for easy use, where one hand holds the CS valve cleaning tool while the other operates the media blaster. An abrasion resistant hose is included to fit on the end of your media blaster and travel down into your intake ports for direct blasting. Unlike doing this without the tool, you do not have to permanently modify your vacuum just to do valve maintenance.

There you have it, folks, quite possibly the weirdest looking CS product ever created but it’s quite useful!  Check out the listing for more details and to see the CorkSport Intake Valve Cleaning Tool in use.

Understanding Intake Systems for Mazdas

The CorkSport Cold Air Box pairs perfectly with the CorkSport Short Ram Intake.

When it comes to the breathability of your Mazda, a short ram intake is the best place to start. The benefits are immediate, the installation is quite simple and it’s genuinely the best first step to getting some power and fun out of your Mazda or Mazdaspeed.

Bringing more air into the intake chamber, the intake system allows you to increase horsepower and torque for your Mazdaspeed. Each is designed to maintain optimal flow and generate ideal performance for your Mazda, with exacting tolerances and using the latest in computer-aided manufacturing techniques to bring you the highest quality and best-performing part for your money. You can expect to gain up to 30+ HP from this simple-to-install short ram intake system.

The CorkSport Cold Air Box pairs perfectly with the CorkSport Short Ram Intake.

Types of Air Intake Systems

Short ram air intakes suck in large amounts of heated air within the engine to help in efficient combustion. These are short and wide pipes because it uses a shorter pipe than the cold air intake, it only has access to warm air near the engine. To make up for this, it sucks in more air than cold air intakes.

Cold air intakes are a type of ram air intake system that works by drawing in cool air from outside and into the Mazda’s engine. This type of intake often has minimal bends and has a long duct with access to cool air. With cooler air coursing through the engine, combustion requires less heat and fuel.

Why Replace Your Mazdaspeed or Mazda Air Intake System

More often than not, car enthusiasts and expert mechanics recommend that you purchase an air intake as soon as possible. Even vehicles of the latest make and models benefit from an aftermarket air intake system. Below are five of the reasons why an air intake system can improve your Mazda engine’s performance.

Get your 2014 Mazda 3 the cold air it needs with the CorkSport cold air box that goes perfectly with the CorkSport SRI.
Mazda 3 Short Ram Intake

Keep in mind, when an intake is paired with a cold air box or battery box, you create a great look for your engine bay and increase your overall Mazda performance. Also, when paired with fuel pump internals, you’ll be able to increase the efficiency, power and set yourself up for future modifications as well!

Why replace your intake system?

1. Increased Acceleration


With an upgraded intake, your Mazda can experience increased horsepower. Upgraded intakes can also increase your engine’s responsiveness when speedy acceleration is required. Because there is more air available and ready for combustion with aftermarket air intakes, your engine reaches the desired speed faster compared to the stock intake that comes with your Mazda. Those who enjoy racing, autocross, or drag strips with their Mazda or who if you just like quick acceleration as soon as the traffic light turns green, an aftermarket air intake can help you enjoy your get up and go a bit more.

2. Greater Fuel Economy


Engines rely on a mixture of fuel and air to create an explosion that powers your Mazdaspeed. When there is not enough air pumping through the engine, your Mazda consumes more gas to compensate for the lack of oxygen. Stock intakes that come with your Mazda are designed to be quiet instead of fuel efficient, and as a result, they tend to use more gasoline. Pumping in more air via an upgraded intake can reduce gas consumption and translate to savings on fuel expenses. For those who are concerned about fuel efficiency…we should note here: that the enhanced sound may cause you to have a heavier foot and decrease your fuel efficiency in exchange for spirited driving.

3. More Effective Filters


The stock air intakes that come with your Mazda normally have disposable paper filters to catch debris. While these filters do their job in trapping particles that may potentially wreak havoc on your engine, the filters eventually require replacement (often a great upsell item for your local technicians). Aftermarket intakes, on the other hand, are equipped with filters that typically have to be cleaned every 20,000 to 50,000 miles (just some soapy water and let it dry completely before reinstallation). This not only saves money but it also provides a more effective filtration method that not only keeps debris out but also lets a larger qty of air inside.

4. Enhanced Sound


Those who like the aggressive sound of a roaring Mazdaspeed engine should enjoy our upgraded intakes the most. Because more air enters through the intake to the engine, it produces a sound that our Mazda enthusiasts find thrilling.


5. Better Overall Performance


With the simple installation of an upgraded intake, you can increase the overall performance of your Mazda. Whether you decide to go for the short ram intake or the cold air intake, you increase your Mazda’s efficiency, speed, power, and sound.

CorkSport Balance Shaft Delete Kit for 2006-2013 DISI MZR

Looking to add some Extra Excitement to your Mazdaspeed?

What if we told you could add extra engine protection at the same time? Introducing the new CorkSport Balance Shaft Delete Kit for 2007-2013 Mazdaspeed 3, 2006-2007 Mazdaspeed 6, and 2007-2012 Mazda CX-7. It contains all the parts you need to safely remove the OE balance shaft from your MZR DISI engine and give it the extra rev-happiness that it needs.

The OE balance shaft is an 18-pound lump that lives in your oil pan to help balance out the natural vibration and harshness that are inherently present with an inline four-cylinder engine. It does this by connecting to a large gear on your crankshaft and using rotating mass to help cancel out the vibrations from the engine. By removing the balance shaft, your engine has less weight to turn and thus, can change RPM more rapidly. If this sounds familiar, it’s because lightweight flywheels do the same thing; remove some of the rotating mass of the engine to gain a faster revving engine and even a few bonus horsepower.

The OE balance shaft needs an oil supply to ensure that it stays well lubricated and does not lock up. The CorkSport BSD Kit uses a stainless steel plug and O-ring to seal this oil passage. The O-ring is not enough to seal and keep the plug in place, however, it is locked down by a securing plate which gets attached using one of the OE balance shaft mounting holes. We chose stainless for its strength over aluminum. By doing so allowed us to create a lower profile plug with a thicker O-ring for better sealing. We were also very careful to choose an O-ring that is safe for all types of oil and safe up to 400°F.

But you may be asking where does the engine protection come from?

Since the OE balance shaft lives in the oil pan, it takes up some volume that could otherwise be used for oil capacity. This means roughly a quart of extra oil can be used once the BSD kit is installed. Also, the CorkSport Balance Shaft Delete Kit comes with an oil pan baffle to help control your oil’s movement during aggressive driving.

While rapidly changing direction or during a long sweeper at high speed, the oil in your oil pan can move around a surprising amount. If the wrong set of circumstances happen, your engine can be starved of oil, which can easily damage vital engine components. The CorkSport Oil Baffle controls your oil’s movement, ensuring that your engine will have a good supply of oil no matter the driving situation.

We again choose stainless over aluminum for the oil baffle, so that it is rigid enough to control your oil and prevent any vibrations or rattles while your engine is running. The oil baffle is made from two laser cut pieces that are then attached using stainless steel rivets to eliminate any risk of corrosion or improper hole alignment.

Note: the CS BSD Kit comes fully assembled and ready for installation.

Since the CorkSport BSD Kit removes a stock component designed to make the car more comfortable, it will naturally have an increase in noise and vibration coming from the engine compartment. As such, we cannot in good conscience recommend this mod to everyone. That does not mean it is unbearable though, Barett at CorkSport still daily drives his fully mounted Mazdaspeed3 with a CS BSD Kit installed.

If you are looking for the next mod to get some more excitement from your Mazdaspeed, look no further than the CorkSport Balance Shaft Delete Kit. After all, how many mods come with some extra engine health as well?

The First and Only Performance Mazdaspeed Throttle Body with NO Sacrifices

Mazdaspeed3 intake manifold and throttle body installed

Many have tried, but few have succeeded to retrofit or modify an existing throttle body to work with the Mazdaspeed DISI MZR platform.

As you know, CorkSport does things a little differently, and as a result, we started from the ground up to create the best performance throttle body possible with no sacrifices to drivability or reliability. Introducing the CorkSport 72mm Throttle Body for 2007-2013 Mazdaspeed 3, 2006-2007 Mazdaspeed 6, and 2007-2012 Mazda CX-7.

Starting from the ground up means 100% brand new parts, no reworked or refurbished components anywhere.  

We start with an aluminum investment cast body that is made to our specific design specifications.

A flat faced throttle plate is added to gain a little bit of extra flow by avoiding the bump of a traditional round pivot shaft.

Finally, new electronics are added that are based upon OE logic to avoid any tuning and calibration issues.

To retain easy installation, we knew we had to keep the OE bolt pattern. With this, we wanted to maximize the throttle plate diameter for maximum flow. We ended up increasing from 60mm to 72mm. This may not sound like a huge increase, but the OE Throttle Body fits inside the CorkSport Throttle Body with plenty of room! The 72mm size also fits well with both 3” and 2.5” intercooler piping to fit almost any TMIC or FMIC setup. Finally, we did away with the OE gasket (which is too small anyway) and replaced it with a durable O-ring that will hold up to oil, gasoline, methanol, and other fueling options that it may come in contact with.


The CorkSport Throttle Body underwent extensive testing to ensure that it will not fail during daily use and to ensure it performs as well as we expect. The throttle plate underwent endurance testing to validate the D-shaped pivot can stand the test of time. During flow bench testing, we found that the CS flows about 150CFM (~33%) better than the OE throttle body when 75% open (accelerator pedal fully depressed).

Check out the graph below for the full data.
Mazdaspeed Throttle Bdy Graph for flowbench testing

In daily driving testing, we noticed better throttle response with no CEL or choppiness. In power testing with a midsized turbo (~GT30 size) we found the throttle body caused faster spool, but when we moved to a big turbo, things got interesting. With a GT35R, the CorkSport Throttle Body caused 100-200RPM faster spooling and an increase in power. Check out the dyno graph down below to see the difference between the CS Throttle body (blue) and the OE throttle body (green).

Dyno stats for the Mazdaspeed 3 Throttle Body

Each throttle body ships with fresh stainless steel mounting hardware, a 3” stainless t-bolt clamp, and your choice of silicone. We have options for FMIC, Mazdaspeed 3 TMIC (which also works for you CX-7 guys), and Mazdaspeed 6 TMIC.

If you’re looking to take your Mazdaspeed3, Mazdaspeed6, or CX-7 to the next level, or squeeze that last bit of power out of your big turbo build, the CorkSport Throttle Body can help you meet your goals.
