Brett’s Mazdaspeed 3 Build: Part 1, The Basic Beginnings

It all started in Phoenix AZ, back in 2014 when I was graduating tech school. I was finally working enough to buy a Mazdaspeed that I had wanted for a while. At this time, it probably would have been smart for me to just start saving, instead of taking on a hefty car payment. But, as a car enthusiast, I’m sure you understand the temptations we often face, and I went for it. Since then, I’ve never looked back.

Red 2013 Mazdaspeed 3

 

I found my 2013 Mazdaspeed3 in the fall. Completely spotless, 6k miles on it, and bone stock. It was truly a blank canvas. At that time I was barely making enough to own the car and pay for insurance. So, modding wasn’t an option at the time. So, as I saved and Saved, I was introduced to Nator Arizona by Thomas Graham, who later became a good friend of mine. He got me involved in the community, and on the right track for learning. From that point on, everything changed, and I loved it.

At the time, I was nothing more than a technician, fresh out of school and stuck on the lube rack for a bit. So, as you can imagine when I finally had enough to get my Accessport and Fuel Pump internals for the Mazdaspeed 3, I was STOKED. I caught the modding bug, and before I knew it, I had bigger aspirations for the car than ever thought I would have had. The next year was filled with countless Nator garage days, fun drives, Mexico pulls, and slowly adding parts when I could afford them.

By mid-2015, my time in AZ was coming to a close. At this point, I had all the basic bolt-ons offered for the Mazdaspeed 3. Rear motor mount, short ram intake, upgraded BPV,  upgraded TMIC, and turbo back exhaust. The car otherwise looked completely stock, just MUCH louder!  The icing on the cake was the pro-tune 320 WHP on Stock turbo with some e85. A couple of days later I departed AZ for my next chapter and got the MS3 on the trailer.

Funny looking back now, how I thought I was done with my Mazdaspeed, and that was enough power to keep me happy. Not even close! The next couple years would be the catalyst that started to shape my MS3 into what it looks like now. Stay tuned for Part 2!

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?

2007-2009 Mazdaspeed 3 Crash Bar

Mazdaspeed 3 FMIC

Want Big Power from your GEN1, but your Intercooler is holding you back?

This was the case for our Engineering Manager Barett and his Mazdaspeed3, so he created his crash bar for a big front mount intercooler; we liked his setup so much that we made it for everyone.

Introducing the CorkSport Mazdaspeed Crash Bar for 2007-2009 Mazdaspeed3; constructed of high-quality laser cut steel with a durable powder-coated finish, it can stand the test of time while giving you room for the big front mount you want.

2007-2009 Mazdaspeed 3 Crashbar

Now let me start off by saying this is not a typical CorkSport part. It is not an easy bolt-in install like most of our other parts.

There is no easy way to remove the OE crash bar without cutting it off. As a result, this install is extensive and more or less permanent. Don’t let all of that scare you off though; this is still a CorkSport part. That means the same great quality and customer service that you’ve all grown accustomed to.

We have made this as easy as we possibly can. Once the OE crash bar is cut off and some trimming done to the headlight surrounds, the bar is located in the correct position based on the OE hood latch support. Then holes are drilled in the OE crash bar support rails to securely mount the CorkSport Crash Bar. No welding required for install.

Now I know what all of you are asking, what about a big FMIC to fit the bar?

Well, we are offering the crash bar by itself and with our 23 ½” x 11” x 3” intercooler that’s been proven on a 550whp car. Since the CorkSport Mazdaspeed3 crash bar was designed to fit this FMIC, brackets come pre-welded in the correct locations to mount to the top of the FMIC.

Also, stainless steel side brackets are included to attach the IC’s lower mounting locations to existing holes on the radiator core support for added stability.

This entire package fits well behind the OE bumper with little to no trimming or modification. OE fog lights stay functional, and you even can utilize the OE toe hook location as it is retained with the CorkSport crash bar.

New Year, New Gains

As the New Year rolls around, most people are looking for a change for the better in their lives.

At CorkSport we think one of the best changes you can make is more power for your Mazdaspeed. We have all the parts you need to liven up your Mazdaspeed3 or Mazdaspeed6 in the New Year.

Safety First

One of the first things to consider when modifying your Speed is the health of its engine. Performing maintenance is very important but it only gets you so far. When adding power, one of the first modifications on your list should be the CorkSport Max Flow Fuel Pump Internals.

These pump internals allow you to maximize your stock fuel system for optimum power capabilities and safer than OE A/R ratios. This means you can add the power you want and have peace of mind that your engine will get the fuel it needs.

Put the Power Down

Like the CS fuel pump internals, the CorkSport Stage 2 RMM for Mazdaspeed 3 will not directly increase the power levels of your car; however, it helps you put all that hard-earned power down. By decreasing the amount the engine can rotate, the Rear Motor Mount allows for reduced wheel hop and torque steer while providing faster throttle response and crisper shift feel.

Even we are surprised how much this engine mount changes how a Mazdaspeed 3 feels. Don’t worry Mazdaspeed 6 guys and gals, we have an RMM for you too.

Improving Airflow

Engines in an extremely simple sense are air pumps; so the faster you can get air in and out of the system, the better. That being said, some of the simplest and easiest power gains you can get from your Mazdaspeed are from upgrading the intake and exhaust. We have seen peak gains of 25ft-lbs and 33WHP from only the CorkSport Stage 2 Intake and a CorkSport Racepipe.

Checkout the dyno sheet below.

Power and torque levels will be further increased if you install a full CorkSport Turbo Back Exhaust instead of just the race pipe section.

The catback exhaust section has proven to gain up to 14WHP while the downpipe section alone has proven to gain up to 21WHP. In the dyno graph below, the downpipe car had a CorkSport Intake installed at the same time as the downpipe (hence the 50hp gain).

If that wasn’t enough flow for you, we also offer 3” and 3.5” intakes for even more airflow into your turbo. Keep in mind though, once you get into those you will need to use a new tune to ensure your car runs optimally. But check out the extra flow you get!

Turbo Upgrade

The CorkSport Drop-In Turbo is a fantastic upgrade to the stock K04 turbo that allows your car to make more power on an equivalent boost pressure. It will work with any mods you already had on your OE Mazdaspeed turbo as the CS turbo is truly a drop in upgrade. With supplemental tuning, fueling, and supporting parts, you can push your Speed to its limits.

The Next Level

CorkSport also manufactures parts that can take your Speed beyond the parts discussed above. A short list of the parts with the best power gains can be seen below:

  • CorkSport Intake Manifold: A higher flowing IM can support much more power than the relatively restrictive OE unit. Best when paired with a larger throttle body.

  • CorkSport Camshafts: Replacement cams with extra lift to provide increased power and torque across the entire RPM range.

  • Bigger CorkSport Turbo? Yes, there is one in development. See this blog post for details.

No matter what your goals are for this year, CorkSport is here to help you achieve them. Whether you just picked up a Mazdaspeed and are unsure where to start, or have been driving one for years and want the excitement you once had back, CorkSport has a part for you.

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.
