Long in development, the Turbo Kit for the 3rd Generation Mazda 3 is finally here. Currently designed for the 2.5L MT equipped vehicles, you can transform your Mazda 3 from a boring 160whp commuter to a (approximate) 280whp “Mazdaspeed” that Mazda never gave us.
Years of development and testing both on the street with our dedicated street car and on the track racing in the SRO TC class with our dedicated, homologated, racecar. We have thousands of track and street driven miles on the turbo kit, proving both its reliability and performance.
This is the only 100% turnkey turbocharger kit for your 2014-2018 Mazda 3 from air filter to downpipe, this kit includes everything to take a stock Mazda 3 from boring to boosted. Not only does this include ALL the physical “turbo kit” parts, but also includes a boost gauge, boost control system, battery, and pre-setup tune for your vehicle to operate on premium gasoline fuel.
The only turnkey turbo kit for the Mazda 3. 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.
Imagine adding 115-125 wheel horsepower and 80-90 wheel torque to your Mazda 3…now image getting to enjoy that added power every time you drive your Mazda 3. 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 Mazda 3.
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 Mazda 3.
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.
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.
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.
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.
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 10000 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.
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.
A custom fitment intercooler was designed for the Mazda 3 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.
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.
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.
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.
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.
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. (NOTE: Overseas customers will need to source an equivalent battery locally. Specifications are provided in the instructions.)
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 3 you get to be a part of the Unicorn Project with a unique shirt, hat, and stickers!
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.
