Love for the Skyactiv

We're going to take apart and upgrade a brand new Mazda 3 with a SkyActiv manual transmission.

We have gotten some great response back from our customers who have the SkyActiv Mazda 3, 6, and CX-5s over the past few years with product suggestions and questions about power, technology, and more.

We're going to take apart and upgrade a brand new Mazda 3 with a SkyActiv manual transmission.

We decided to have an in-house example of Mazda’s current sport model of the Mazda 3, a 2015 2.5 liter SkyActiv manual transmission. As everyone’s favorite television series host has put it in the past: There is no better way to test the breed than motorsports. So that is exactly what we are going to do with this brand new Mazda 3. Strip the interior, outfit it with CorkSport parts, install some safety gear, and go racing.

Want some new Mazda 3 parts? We'll be selling off just about everything.

Yes. We are really going to take apart a perfectly good car to race on the track with a bunch of other people who suffer from the same mental disorder. We will be posting regular updates on the car as we proceed through the build, which will include time on our dyno and results on the races.

This also means there will be a garage sale on brand new parts from this car, interior, wheels, etc. It has every option so if you want something shoot us an email.

Stay tuned for updates.

Our White Paper for the Mazdaspeed Replacement Turbocharger

We’ve been gearing up for months for the release of our turbocharger for the Gen 1 and Gen 2 Mazdaspeed 3 and 2006-2007 Mazdaspeed 6, and on Wednesday the wait was over.

CorkSport Mazdaspeed 3 Replacement Turbocharger

After countless hours designing, testing, and adjusting, we released our drop-in turbo for the Mazdaspeed, and we’re very proud of it—and thrilled about the responses we’ve already received from our beta testers. (See the first reviews on the listing.)

Beta testers for the new Mazda turbocharger

Obviously, with a product this big, we wanted to inform our CorkSport customers as much as possible about the advantages of our turbo vs. the OEM and competitors, and how much power buyers could expect to gain.

Barett wrote a huge white paper on the turbocharger, detailing all of this. From the benefit of a drop-in (no new coolant lines, oil lines, or a intake system are required to install and operate it) to the details of a turbocharger’s anatomy, you can read all about what makes our turbo stand apart.

Our goal was to create a performance-driven turbocharger that wouldn’t break your bank or require a mechanical engineering degree to install. We’re happy to say we succeeded, but see for yourself.

Order your Mazdaspeed turbocharger here today, though be sure to read Barett’s white paper first. It’s long but good.

Cheers.

The New CorkSport Steering Wheel for 2007-2009 Mazdaspeed 3

Increase your Mazdaspeed's handling and style with this new leather steering wheel.

Looking to add a little style to the interior of your Genjuan? Or maybe you’re searching for another performance product to give you the edge? What if I told you I could give you both of those with one performance product?

Introducing the new CorkSport Performance Steering Wheel for 2007-2009 Mazdaspeed 3!

Increase your Mazdaspeed's handling and style with this new leather steering wheel.

No stitching is required! The CorkSport Performance Steering Wheel was designed to be a direct OEM replacement. It works flawlessly with the OEM steering column, covers, button panels, and airbag for a stress-free 30-minute installation. Check out the images below: On the left shows exactly what you would receive in the package. On the right is a fully assembled steering wheel with all the OEM components.

Installing Mazdaspeed 3 Steering Wheel

Now I have to admit, when this product idea (Big thanks to Brett Ross!) came across my desk, I was a bit skeptical. I’m not one to spend money on aesthetics on my Mazdaspeed 3. So we got a prototype manufactured, and I installed it in my car to begin the R&D process. Within minutes, I was sold—and not just by how good it looked in my 09’ MS3, but by how much more connected I felt with the car.

Mazdaspeed 3 Steering Wheel for Better Driving Experience

While driving I saw the value in a performance steering wheel—things like the hand-wrapped and stitched leather that has a slight texture and plush feel to it. The perforated leather in the high-use areas is a great addition so your hands won’t get clammy on spirited drives. The wheel diameter is the same, but the thickness of the wheel has been increased, which is much more comfortable for long drives and canyon carving. The flat bottom gives it a more aggressive feel and actually makes it easier to get in and out of the car since I’m 6’ 2” tall. All that said, probably the most exciting feature of the CorkSport Performance Steering Wheel are the aggressive thumb grooves. These help you lock your hands in place, giving you more confidence in the twisty roads and while fighting the lovely torque steer.

Why You Need a New Mazdaspeed 3 Steering Wheel

Trust me when I say, you need to try the CorkSport Performance Mazdaspeed 3 Steering Wheel. You will be pleasantly surprised.

Why You Need Injector Seals – Part 1

Why You Need Injector Seals Part 1 

 

If you’re a car enthusiast that wants performance, reliability, and of course cost effective upgrades, then injector seals should be on your wish list…wait doesn’t everybody want that for their Mazda? I think so; let me tell you why…

As car enthusiasts we all ultimately seek more power. It starts with an air intake, and then we need more fuel, which leads to the high flow pump internals, but that only scratches the surface. Oh then, Mr. Cobb finds himself plugged into your OBD II port and you’re running 20+ psi grinning ear-to-ear.  It’s OK, we are all guilty; some more than others, but something has to give and so it does. What that is that gives, well it’s easy to miss, because your car is smart and compensates for it, but it’s happening. You’ve got bad injector seals! Don’t believe me?  I’ll prove it!

You have probably run across injector seals while shopping for various other parts, but didn’t pay attention to them. Essentially, they are fancy little cups that fit over the nozzle of the injector.  Now for the real question: have you ever seen an OEM injector seal? Doubtful. They are tiny steel washers designed to crush and seal…the stock ones are pitiful.

What happens when a seal doesn’t seal? All of your hard earned power escapes around it, making a mess of the injector and fuel rail. Look below you’ll see that the injector ports in the cylinder head are filthy.

Seals-Rail-Intake-Manifold-CorkSport

Starting on the left, the injector port is clean and shiny like freshly machined aluminum.  Now look at the port farthest to right; black as night and a bit gritty.  That seal gave up before the rest and I have a sneaking suspicion that it has to do with the EGR going through mainly that cylinder, but we will save that for another day. Here is a close up of the dirty injector before and after a scotchbrite rub down.

Seals-Rail-Intake-Manifold-CorkSport-Injectors-Tokay-DISI Seals-Rail-Intake-Manifold-CorkSport-Injectors-Tokay-DISI-New Now that is a big difference huh! Do you believe me yet? Maybe? Let’s compare the seals…

Look at that picture below and let that sink in…

New Seals: Seals-Rail-Intake-Manifold-CorkSport-Berrylium-Copper-Tokay-Injector

 

OEM Seals: Seals-Rail-Intake-Manifold-CorkSport-Berrylium-Copper-Original-Injector-OEM-used

Are you flabbergasted like I am? Huge difference! So, why do the differences matter?  First off, it’s no longer just a washer with one sealing surface.  It’s a cup, so it seals in the OEM location AND along the side of the cup.  That’s not all! The secret is in the design (which is all thanks to @Tokay444; from MazdaSpeedForums.org).  Here is how it works. The lip at the bottom of the cup is flared just a bit so that it crushes down tight against the cylinder head, and as it crushes down it also crushes outward, pushing against the wall of the port much like an O-ring.

These four little beryllium copper cups are cheap and reliable, but how do they improve performance?  Let’s go back to our power hungry example running 20+ psi; with blow-by around the injector seal. That leak has now disappeared, which means if it’s not escaping there then it must be doing “something”.  That “something” is more power to your wheels and a happy MZR.  Our previous dyno testing with the OEM seals and 21psi were never consistent, declining with each consecutive run. Our new seals restore that decline, each dyno pull now falls on the previous line perfectly and that was in 90+ degree weather.

Have I convinced you yet? Stay tuned for part 2; we are going to put some hard miles on the MS3 and then inspect the seals.
