2018+ Mazda 6 Turbo Lowering Springs

2018 Mazda 6 on CorkSport Lowering Springs

We at CorkSport are happy to introduce the Sport Lowering Springs for 2018+ Mazda 6 equipped with the 2.5L turbocharged engine. We took a fresh approach to spring design to offer you the best combination of style, ride quality, and handling in a package that fits just like OEM. The new Mazda 6 looks great, but a functional drop gives it just what it needs to look even better. Combine this with the new handling characteristics and your MZ6 2.5T transforms from a fun grocery getter to something you can actually enjoy on backroads.

Ride Height

Let’s start off with the big one: ride height changes. These springs offer a conservative drop from the stock springs with about 1 inch lower in the front and about 0.75 inches lower in the rear. We chose this height as it offers a great new look without sacrificing any of the daily drivability of the Mazda6. This height clears the typical driveway with no issues, and retains plenty of suspension travel, even when fully loaded with 5 adults and weight in the trunk. Check out the image below for a direct comparison to a fully stock MZ6.

Handling

The height drop will be noticed when you’re outside the car, but the handling improvements will be apparent when driving. By lowering the center of gravity and stiffening the springs, body roll is reduced in corners, giving you extra confidence when attacking that backroad. In addition, we stiffened the rear springs more than the fronts, reducing understeer. By number, this meant 3.8K front springs (25% stiffer than OEM) and 7.3K rear springs (45% stiffer than OEM). Derrick, our resident racecar driver and MZ6T owner, loves the new setup.

While this may sound like a big jump, they ride similarly to the OEM springs. We used a natural frequency analysis to ensure we achieved comfortable characteristics over bumps. Read the last half of this blog for more info on what that means (it’s complicated but awesome). Part of the great ride is the OEM dampers (shocks and struts). The spring rates we chose fit well with the stock shocks and struts to prevent any bounciness, plus, the conservative drop ensures you are in the normal operating range of the dampers. This means no prematurely worn shocks/struts due to springs that are too low.

Material Quality

Last but not least, the CS Sport Lowering Springs are made from high tensile strength spring steel and come powder coated in an OEM style black for long-lasting quality and corrosion resistance. They install just like stock, reusing all your OEM components. The only permanent modification is trimming the bump stops to match OEM suspension travel.

Be sure to check out the product listing for more images, a product video with more comparisons to OEM, and pricing. Make your new Mazda 6 yours with just the right styling and handling boost from CorkSport.


That about does it for the Mazda 6 2.5T Sport Lowering Springs. Be sure to let us know if you have any questions-suspension is hard, even for us! Lastly, be sure to share your MZ6T with us by using #CorkSport.

CorkSport Injector Puller

For the Mazdaspeed 3, Mazdaspeed 6 & CX7

After years of popular requests, we have something that we are very excited to announce! The CorkSport Injector Puller is here, and ready to assist you with your DIY, or shop needs.

With great power, comes great responsibility! And owning a Mazdaspeed may have made you aware by now of how troublesome removing a GDI injector can be. We designed this to assist you.

YOU CAN NOW SAY GOODBYE TO:
  • Twisting a seized injector until it breaks loose
  • Rigging up some method to pull or pry out the injector
  • Beat up hands
  • Beat up injectors
  • Hours of lost time

Now, I know what you are thinking: we may be late to the party. We are aware that we are not the first ones to make such a tool, however, we wanted to ensure that we made one of the highest quality that can be used time and time again. We love that you guys buy our seals, and we wanted to help ease the installation as much as possible.

With its stainless construction, Nator can truly make use of this when it gets passed around, because it won’t deteriorate with use.

As the OE seals fail, carbon starts to built up around the injector and seal and really locks that sucker in there over time. Sometimes an injector has to be sacrificed as seen above. But, It’s amazing how much easier the proper tool can make the job.

Although it may resemble a shake weight a bit, its just your normal slide hammer style tool with a custom head designed to perfeclty fit the DISI Injector.

HOW TO USE:

  1. Take off O-Rings that will be on the tip of the Injector where it goes into the Fuel Rail. Be sure to store those in a safe place.
  2. Slide the head of the tool into position as shown.
  3. You will then put tension on the tool pulling backwards.
  4. Use your other hand to slide the hammer backwards until it hits the lock nut on the back. Repeat until the stubborn injector finally breaks free.

Mazda’s Game Changer

Recent news has been circulating about the new Mazda and Toyota joint production plant and what will be built there.  In a few news articles, Masamichi Kogai has been quoted saying Mazda will introduce a new and different type of CUV (crossover utility vehicle).

I have been thinking about that statement about a new and different type SUV. Looking in the marketplace, you have pretty much everything out there in size, shape, and quality.  I think there is something which is getting lost in the translation of this message.

My bet is it will be something totally new for Mazda.  

Back in 2015, Mazda showed off the Koeru concept which was hinting to future models of crossover SUVs.

Looking at the current styling and the concept cars Mazda has laid out at the Tokyo Auto Show with the Mazda 3 Kai concept this year.

The front end styling has been sharpened on this concept car, but it isn’t too far outside of what Mazda is currently offering. The changed roofline at the rear points is designed to maximize cargo space, but in a good-looking package.

I will go out on a limb and guess that Mazda is probably working on a new motor to power whatever the upcoming CUV is going to be.

The most powerful motor Mazda offers right now is the 2.5 Skyactiv turbo engine, which powers the Cx-9 and soon to be offered in the Mazda 6. This motor is based on the older Skyactiv tech though, and with Masamichi saying the new vehicle will something new, my guess is that we should expect to see another tech marvel being produced.

The last thought I have on this with Mazda is this:

If they’re coming out with something new, we may see a large-sized vehicle to go up against the truck-based SUVs from other manufacturers. It is a direction Mazda has not gone before and lines up with the statements they are giving us.

Time will tell!

New “Mazdaspeed” Finally Coming Down the Pipeline

In case you haven’t heard, Mazda officially announced on November 15th that they are bringing the turbocharged 2.5L CX-9 engine to the Mazda 6.

Now, this announcement did not come with a huge amount of information, but it got everyone here at CorkSport all sorts of stirred up. This fantastic news comes coupled with a new facelift, better quality interior, and a few extra options. Check out the teaser shot down below, in my opinion the CX-5 grill looks great on the 6.

While we do not know if this new turbocharged Mazda 6 will carry the Mazdaspeed badge, we do know it will sure feel like a Mazdaspeed.

The SkyActiv-G 2.5T produces 250hp and 310lb-ft while on premium fuel. That power and torque are more than enough to move around the big CX-9 so it will definitely be interesting in the Mazda 6 that weighs almost 1000lbs less. Two more factors remain for the new 6 to truly be a Mazdaspeed6: manual transmission and AWD.

Since the CX-9 and Mazda6 are based on the same platform and have similar chassis, carrying over the AWD system with the engine is a distinct possibility. Plus, Mazda already offers the 6 in AWD in the European and Japanese Markets. The big question remaining then is the manual transmission. While the manual mode on the CX-9 automatic is nice, it is just not the same as a full-bore manual gearbox. It’s not looking too good as the CX-9 only comes in auto and the teaser images just show an automatic but hopefully Mazda can surprise us with a manual transmission.

Since this 2.5T has been in the CX-9 for a few years now we at CorkSport have had a few opportunities to check out the engine, see how it’s packaged, and look for potential performance gains.

What follows are simply observations that we have made, don’t get too excited (yet):

  • The turbo inlet pipe gets quite small on its route from the airbox to the turbo. Enlarging this would definitely help the turbo breathe better.
  • The exhaust is fairly restrictive at about 2 3/8”.
  • There is a good amount of space where the turbo lives for a high-flow downpipe and even turbo upgrades.

Additionally, this engine was designed to fit in the same compartment as the naturally aspirated 2.5L so we may even get some Mazda 3 love down the road if the SkyActiv-X doesn’t steal every engine bay.

This new Mazda 6 may be coming sooner than you expect.

All Mazda models have gotten a 2018 model year, except the Mazda 6 which is currently at 2017.5 and the Miata that’s stuck all the way back in 2017. Hopefully this means the 2018 model year Mazda 6 has the turbo option. Maybe Mazda is even planning a 2018 Miata update but only time will tell.

Look for more info on the new “Mazdaspeed” 6 during its full unveiling at the L.A. Auto Show on November 29th. We’re just as excited as all of you and to be honest, if a manual option gets announced, one will likely find its way into the garage. Stay tuned to the CorkSport Blog, Instagram, and Facebook to make sure you don’t miss anything!

CorkSport BIG Turbo

Mazdaspeed 3 big turbo upgrade

Good day boosted enthusiast!

We wanted to take some time to give you all a quick update on one of the many projects we have brewing up here at CorkSport Headquarters.

The project I’m referencing, in general, is our 2nd turbocharger upgrade for the Mazdaspeed 3, Mazdaspeed 6 and CX-7. This unit is a substantial upgrade over our current 18G turbocharger. This Turbo will cater to those looking to take their performance and power goals to a higher level.

Not only will it be capable of putting you well into the 465whp range but this CorkSport Turbo upgrade will be able to do it without giving up on reliability and throttle response.  

It will be very beneficial to those who have mildly-built blocks and a supporting fuel system that will allow them to get higher in the HP range.

So, let’s talk about some of the features you can expect on the upgrade and why we decided to utilize them.

 

 

Let’s start at the heart of the Turbocharger.

The new CorkSport turbo will take full use of a GTX3076R center housing and rotating assembly (CHRA). The unit is equipped with a fully sealed ball bearing cartridge, which is a nice upgrade when compared to a standard journal bearing unit. We chose to go with a ball bearing unit for a few reasons.

  1. The enclosed design of a ball bearing system allows us to eliminate the need for a thrust bearing, which can account for about 40% of the bearing system drag on the turbos rotor assembly.
  2. Ball bearings reduce the viscous drag, which allows a ball bearing unit the ability to spool up about 15% faster than its journal bearing equivalent.

The next thing you will notice on the new Mazdaspeed Turbocharger upgrade is the holes that are drilled into the compressor cover. These little holes are known as anti-surge ports and are intended to expand the turbochargers compressor map. The ports function to move the surge line further left on the compressor map which gives the Mazdaspeed turbo some more headroom before it falls out of its efficiency island. Anti-surge ports are becoming increasingly more popular in modern performance turbochargers and with great reason. They offer some unique benefits as mentioned and will be fully integrated into our unit.

 

Last but not least, as with our CorkSport Turbo, this bigger Mazdaspeed Turbo will once-again be a true drop-in unit; minus the 4” compressor inlet.

There will be no cutting, modifying, sourcing oil and coolant lines, running to the store to buy couplers, etc. This unit will come with everything you need to have a trouble-free install. As with the current CorkSport 18G turbocharger, the new Garrett-based design will come with all studs, gaskets, washers, and knowledge that you need to have a nice weekend install.

So keep your eyes peeled as we get closer to delivering more performance for the Mazda community!
