The CorkSport Advantage
Turnkey Kit:
The only turnkey turbo kit for the Mazda 3/Mazda 6. By turnkey we mean EVERYTHING, which means you do not have to hunt for or DIY anything to convert your Mazda to a boosted setup. We have done all the work to make this the most complete kit available today. From air filter to downpipe, and everything in-between. This also includes the electronics to properly control the ECU and boost. Heck, we even threw in an exclusive “unicorn” swag pack with stickers, shirt, and hat.
Power:
Imagine adding 115-125 wheel horsepower and 80-90 wheel torque to your Mazda 3/6…now image getting to enjoy that added power every time you drive your Mazda. That’s what you get with the CorkSport Turbo Kit. A 75% increase in power output at your fingertips. This is the most cost effective power gains you will ever have for your 3rd Gen Mazda 3 and Mazda 6.
Design:
The entire kit is designed to work as a complete system, that’s how we have developed a turnkey kit without compromise. Everything started from scratch and thought through to achieve the best possible result for your Mazda6 and Mazda3.
Turbocharger:
A custom spec twin-scroll turbo is utilized for fast turbo response and the internally waste gated housing provided boost control that is quite and cost effective. Don’t be mistaken however, this turbo loves to make “turbo noises" that you can clearly hear from the cabin. Check out the videos to see what we are talking about.
Based on a MHI turbocharger, the CHRA is liquid cooled and oil-lubricated for long lasting durability. The compressor housing is finished in a black textured powder coat and the turbo comes to your door with the studs installed and the wastegate set to the proper spring pressure.
Cast SS Manifold:
A cast manifold may not seem like the obvious manufacturing choice, but when it comes to durability, reliability, and performance a properly designed cast manifold will always outperform and outlive a fabricated manifold. That’s why we invested in a 304 stainless steel cast design.
Fitment:
Nobody wants a turbo kit that looks out of place in their engine bay… The CorkSport Turbo Kit delivers with a feel and look that is just “racecar” enough but could be overlooked as OEM with some simple black powder coated pipes. The simplicity and clean routing of the kit keeps your engine bay clean and tidy but will standout at the shows.
Track Tested:
We’ve spent thousands of miles on various closed circuit tracks around the country with our 2015 Mazda 3 Racecar. Fully caged and fully sent, this is the original test mule for the CorkSport Turbo Kit.
Street Proven:
While the Racecar is fun, it can’t be driven on the street legally, so we picked up this 2018 Mazda 3 GT to complete all of our street driven testing. With more than 21000 miles of street testing, we have been able to work out the daily driving feel and power delivery for you. The goal was a boosted Mazda 3 that can hit the track and take you to work every day without issue. That’s exactly what we’ve achieved.
Electronic Boost Control:
Unlike other incomplete turbo options, CorkSport’s turbo kit includes a TurboSmart E-Boost electronic boost control system for superior boost control and boost curve to optimize power and torque delivery of your Mazda 3. This is important for a powerful and reliable car with the added boost. You can also monitor boost with the controller and the included boost gauge.
Stealth Intercooler:
A custom fitment intercooler was designed for the Mazda 3 and Mazda 6 to fit like OEM and support up to 400hp worth of power. No major trimming/cutting is required and it fits behind the OEM bumper shell. The black finish hides the intercooler without sacrificing performance.
Pre-Setup Oil Pan:
Turbochargers require an oil feed and oil drain for proper operation. The only routing possible for the oil drain was a custom stainless fitting that must be inserted into the OEM oil pan. To keep things as simple as possible for you, an OEM oil pan is supplied with the custom drain fitting already installed and ready to use. You only need to swap the oil pan onto your Mazda.
Simple Plumbing:
Simplicity is key when we are talking about a complete turnkey turbo kit for a normally non-boosted vehicle. We took that to heart with the design of the charge piping. Only two pieces of piping and four pieces of silicone complete the boosted plumbing. This keeps the install simple and the chance for boost leaks low.
High quality 4-ply silicone couplers and thick wall precision bent aluminum piping is used for reliability and performance.
Complete Hardware:
Avoid the trips to the hardware store with CorkSport’s complete turnkey kit. All the needed hardware, small clamps, and accessories to get your Mazda boosted are included.
Quality Clamping:
T-bolt clamps are used for all boosted and larger diameter connections for their superior clamping performance and durability. Small diameter connections use stainless worm gear clamps.
Included Battery and Tray:
In order to route the intake system behind the battery, we had to change the battery. The included battery has been proven to handle street and track abuse along with the cold PNW winters. 550CA/450CCA make this compact AGM battery a great choice for your boosted Mazda. Stainless steel battery tray and ECU relocation bracket hold everything in place. If you are located outside of North America you will need to source a battery locally. Contact our sales team so we can get you specifics and also lower the shipping cost as it will go out sans battery.
Unicorn Power:
This might seem silly…well actually it is, but that’s what makes it fun. We dubbed this the “Unicorn” project given its challenges to finally happen. One of the owners daughters drew a unicorn for the Mazda 3 Racecar and its stuck ever since. Now, when you boost your Mazda you get to be a part of the Unicorn Project with a unique shirt, hat, and stickers!
Exhaust Size Matter:
On turbocharger engines the exhaust size can have a significant effect on the overall power output. In the below graph you can see the result of using different size exhaust systems. We highly recommend upgrading to an 80mm cat-back exhaust for optimal performance. *OEM & 60mm Dynos were updated 5/18/2022 after optimizing boost targets for each specific exhaust setup.

I’ve had this turbo kit installed since around October of 2023, so I’ve had ample time to mess around with the setup and learn about it. Prior to boosting this car, I already had basically the entire catalog thrown at it - but this elevated my car to the next level. Let me just start by saying that if you know what it costs to build a boosted car, then you KNOW that this price is insanely affordable given what is included in here. What kind of turbo kit can you find that included cast 304 stainless manifold, downpipe, charge piping, boost controller, boost gauge, intercooler, tune, AND a beautiful MHI based 64mm ceramic ball bearing turbo. The kit is 100% comprehensive - includes everything you need to get from start to finish down to the nuts and bolts. The install can be intimidating but everything is pretty straightforward aside from some wiring portions. Having some friends along for the ride will definitely help the install go much faster, especially when fitting in the downpipe. The driving experience is wild compared to stock - boost hits like a truck on this car. When you want to put around town like an NPC, you can still do that… but as soon as you wanna hit the beans you have a LOT of power on tap. The car is smooth and responsive with the turbo kit, and quite frankly the gas mileage is just as good if not better than when I was NA ironically. I just drove down to Virginia and averaged 32mpg all the way from Chicago. I really cannot emphasize enough how much the driving experience is improved with the addition of a turbo on this car - it’s like the car was meant for this, a modern day Speed3 that we never got to see from the factory. CorkSport is also constantly improving this kit, and sending updates as they become available… for instance they recently developed new intake piping that brings the intake from the firewall back up front to a more OEM location. They sent this updated piping to every existing turbo kit owner free of charge. I love a company that will stand by their product and continuously push for improvement! If you are on the fence about the kit, just DO IT!

When I got my M3 I already started modifying it only after a week of owning it. I bought a lot of mods from corksport and made it a very fun car. The only thing that was missing was the power. The price is a lot and I held off for awhile not buying it. I just couldn't justify that kind of money. I still wanted more power. So I bought the Turbo Kit. The kit wakes up the car so much and gives it character. After 5.5k miles I have never once regretted my purchase and still love driving it every time I start the engine. You can do all the work by yourself. I did it in a basement with a couple long nights. Great company they know what they are doing. Have loved every purchase I have made. (Still want to see a MS style wing for the hatchback and would buy it immediately of course)

Welp. I've had this thing installed for 9 months now. Nine. Thats enough time for some things to uh develop. In this last 9 months, I have managed to put on a whopping 5000 miles on my 2018 Mazda 3 2.5 Automatic. Yeah.. I know. Automatic. Bleh. Alright lets get from the very start. Packaging. 10/9. Eggcellent. Everything was TIGHT. Got some merch and rice crispies from the team. Few months past, My buddies Josh and Dimitri came up to Ohio (gross), and helped me knock this thing out. We Spent a good 3 full days installing this kit, everything went smoothly, the instructions are very well laid out. Drove the car for a few months, and it has been doing great. The Cold starts each morning are insane, it sounds like a jet is starting up. The only issue I've had which did affect the turbo kits performance was.. my plugs were fouling out. Luckily this was a $40 fix and it was just the rear o2 Sensor was just bad. Replaced with OEM and the car has been doing perfect since! It is currently averaging 50 degree weather here, and man, this turbo kit is loving it. It feels stupid quick. its incredible to drive. If you're looking to adding power to your 3rd Gen 3 or 6. I would highly recommend this turbo kit. Install can be done by someone who has worked on cars, and can do some simple wiring, or it can easily be completed by someone at a shop.

Quick review of the CorkSport 3rd gen turbo kit. Kit has around 15k miles on it. The car has 30k on it. First thing I noticed is that if you want to have fun with this car do yourself a favor pick up that RSB and upgrade that clutch. Supporting mods are almost more important when achieving a jump in power like this. No dyno numbers yet on my build but I estimate that this kit gives very close if not 300whp. As they said results will vary. This is 100% a setup meant for roll races. When you’re in boost it smacks you back slightly then gives you a second hit as soon as 6+psi and 4K rpm hits. This is the most fun I’ve had in a car like this. It makes you want to drive and enjoy every second of it. The turbo noises keep you engaged and beg you to waste more gas. Hopefully we see a fueling solution soon to get some more power out of good ol' reliable 3rd gens. Let’s get to some issues I’ve had. Cylinder 1 misfires are common for me after a redline pull in 3rd or 4th. This is due to my plugs they need more frequent replacing after seeing how hard I beat on this car. All other aspects are perfectly engineered and work flawlessly with the current systems in the car. Some may not see the worth in a 6k turbo kit, but this kit has absolutely everything and super clear instructions. Trust me I’ve never done anything beyond oil changes before installing the kit myself. The support of the CorkSport crew is amazing and they really have your back in unsure times. This is my 6 month update on the kit. feel free to have your own opinion but this is the best 6k I have ever spent. Thanks Corksport!

The loss of the MazdaSpeed 3 after the 2013 model year left many enthusiasts wanting after Mazda had to take the company in a brand new direction. The third generation Mazda 3, while a fun and capable platform for what it is, has long been limited to simple bolt-ons and tunes. Today, this ends with the introduction of CorkSport’s long-awaited turbo kit. To begin, as a part of CorkSport’s sponsored driver program I have been incredibly fortunate and grateful to be a part of the kits beta testing and abuse process. We found out quickly that my stock clutch was not up to the task of the added power. This was not the kits fault as my stock part had very little life left in it due to learning manual on the car and having been given nearly 40,000 harsh miles of spirited driving and autocross/track events. All of CorkSport’s in house cars have been using the stock clutch for the entire project, but higher mile or more abused vehicles may need a replacement or upgrade. I have been running an upgraded clutch for a while now without any issues, and over the past year of testing the car has been rock solid. Upon receiving your kit there will be a lot to unpack, both physically and mentally. There are a lot of steps and parts involved but everything you will need is included, no exceptions. Be prepared to have your vehicle down for a few days as you work your way through the instructions page by page, but the kit will then come together perfectly upon completion and reward you with an exciting first start up. It is entirely possible to do this in your driveway but you may want an extra set of hands for some steps. If you have not already, I would consider getting an oil catch can just as a preventative maintenance measure and while the car is apart. After installation I immediately embarked on a 600 mile road trip, attended multiple autocross events, a track day, and another road trip putting on an additional 1000 miles in a weekend all within the first four months. I have since put over 10,000 total miles on in under a year and counting. This kit and vehicle have much more to give and there are no signs of wanting to give up. This brings me to maintenance; there has been no oil or coolant burn, no excessive darkening of fluids, and no excessive oil catch can deposits. You can run the car like you normally would and give it much more without worrying about what will break. This engine is more robust than some have expected, and between CorkSport’s dedicated track car, and the two street cars running the kit there are tens of thousands of miles under boost and severe conditions without issue. This kit has been very well thought out and has been tested rigorously in all potential aspects. Fuel economy is identical to being naturally aspirated due to the vehicle not constantly being under boost therefore not requiring more fuel. Typical driving behavior is even better than NA with the included tune. When not in boost the car is compliant and unassuming, when you downshift and step on it your vehicle will take on a whole new personality as the turbo lights up and produces the much appreciated noises and thrust you have yearned for. Power delivery is smooth and consistent well past triple digit speedometer readouts where the stock counterparts are lacking past interstate speeds. Shifting from 1st through to 6th has impressive consistency, downshifting and rev matching is incredibly crisp and keeps the power available. It just works. This platform has always been a great handling and capable one but adding boost will elevate it to the next level. The more you beat on it the more it seems to want it, this is what the third gen mazdaspeed could and should have been. Combined with coilovers, proper tires, a big brake kit and rear sway bar your third gen mazda 3 will become a whole new beast. Coming out of corners you will have the missing thrust you have always wanted. When passing on the interstate or merging you will have power on tap, when bombing down back roads you will be greeted by turbo noises and the occasional exhaust pop encouraging you to push further. If you are looking to get the most of your third generation Mazda 3, then this is the ultimate all-inclusive solution you are looking for. I would recommend suspension, brake, exhaust, and engine mount upgrades to get the most out of the additional power. When modified to this extent the car becomes an entirely different experience and everything you could hope for from a vehicle that was never intended to perform at this level. Be prepared to fall in love all over again and experience the anticipation of the next chance you get to take it out for a drive. I cannot express enough, my deep satisfaction with what this vehicle has become and am excited to see how far it can actually go in the future.

What stands out to me is how complete this kit is. You literally get everything you need, without having to go elsewhere, all in one order. Complete from bolt on, to being tuned, without having to spend any more on a tuning solution or dyno time. The quality and fitment is bar none. From how everything fits, lines up, included tapped oil pan, etc. Yes, it's a bit inclusive for the install, but this kit makes installing a turbo kit on a naturally aspirated car, as easy as it can be, especially with the instructions and videos provided. The CorkSport Turbo Kit turns the mild mannered commuter car into something that makes driving the car very enjoyable! I call it the K04 killer, because it is. A stock turbo Mazdaspeed will have a hard time with this, and in my opinion, how the car should have come stock from Mazda. It's very controllable and predictable and drives like a stock car when you want it to, while having the extra power ready when you need it. Whether you are racing grandma in her corolla, enjoying your favorite on ramp, or heading out to your local drag strip or autocross course. I had the pleasure of spending several months with the CorkSport R&D car, while tuning the car and getting it dialed in. A lot of the quirks I hated about the stock mapping of a stock car are now a thing of the past. I highly recommend the kit due to the high quality and reliability of the kit and tuning.
