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.

Now the question is do you want to make it go fast and harness the power that this turbo is built for? Keep reading and we’ll provide some other awesome upgrades that are the next step once you have your turbo installed and running. Oh, and if you are looking for a proven path to make 400WHP, check out our Chasing 400 WHP Blog here!

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!

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!

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)

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. Our techs are available for any questions you have and are ready to assist with planning your Mazdaspeed build path!

3 Turbos and a Supercharger for Mazda

A year ago we were all complaining at Mazda saying “where is the forced induction?” and it looks like Mazda was listening.

First up is the Mazda 6 turbo which Mazda has priced to sell as you can get into a GT Mazda 6 turbo pretty affordably. Granted there is no manual gearbox but I can say first hand they are fun to drive and the torque from the boost is really addictive. I find it hard not to want to screw with people in the 6 since it has no visible exterior queues that it has a turbo. I will say we have already been tweaking on the car and found that it does respond well to modifications.

Second up is the SkyactivX which Mazda says will be available later this year. This engine is supercharged to allow it to be an HCCI engine, aka compression gas motor. The forced induction setup is pretty tricky and the initial look I have done with it I get we can crank it up a bit more to improve the efficiency of the intercooler to give it more heat capacity to allow you to use the boost longer in the car for high-performance driving. Until it shows up we won’t know for sure but we are looking forward to trying it out.

Third is the Mazda 6 diesel which uses 2 turbos. Mazda tried to release the 6 in the past but when they couldn’t match what VW was doing they declined to just “Send It” as the car didn’t perform as they needed it to and still hit the emissions targets without urea injection. Later we all found out VW was a cheating bastard which kept us from having the Skyactiv diesel engine here to crank up the boost on. About every publication in the planet has posted up about the 2018 Mazda 6 diesel being seen in the EPA parking lot for testing along with a pile of other diesel models. This is a good sign if Mazda says it will pass the US emissions and handed one over to the EPA we can expect a Mazda 6 turbo soon.

I am going out on a limb here and saying that besides the announced Mazda 3 Skyactiv we are going to get something fun in the new Mazda 3 ~ a year after the initial release. If you are reading this Mazda, please give us a Mazda 3 GT with a turbo motor.

Mazda 3 TCR

An interesting article popped up a few days ago in which John Dagy, a journalist with Sportscar365, was discussing the TCR class of cars with John Doonan, the head of Mazda Motorsports program.

I have been following the TCR series for a while now with some interest in it as the car Mazda offers that fits best is the Mazda 3, and I enjoy the time I have had racing CorkSport’s Gen3 Mazda 3.

What is nice about the series is that it is meant to race four-door saloons, all with a 2.0 turbo motor and a price-capped ceiling of 135,000. Most people would freak out a bit with that price but what you are getting is a fully developed car with a spec sheet. Each manufacturer designates a builder, whether themselves or a shop, to assemble the cars and provide support.

Mazda is in an interesting spot; they have their successful Global MX5 cup series and the IMSA Prototypes with Joest, but there is a middle-ground hole that has been filled with the older NC Miatas. With the NCs not being a current production model, it makes sense to get something in there to fill in the blanks.

In the past, Mazda had used the Mazdaspeed 3 as the basis, and it did well capturing the championships in PWC and IMSA ST class, but the lack of a turbo model makes this a challenge.

One option out there would be to use one of our upcoming 2.5 Skyactiv Mazda 3 turbo kits and bridge the gap so to speak to have a powerplant. Granted the turbo kit is for the 2.5 but with enough encouragement and feedback from people, the 2.0 kit is looking likely.

Work on some aero and really good suspension, and you would be set. Maybe I am just daydreaming too much at work again….
