The First and Only Performance Mazdaspeed Throttle Body with NO Sacrifices

Mazdaspeed3 intake manifold and throttle body installed

Many have tried, but few have succeeded to retrofit or modify an existing throttle body to work with the Mazdaspeed DISI MZR platform.

As you know, CorkSport does things a little differently, and as a result, we started from the ground up to create the best performance throttle body possible with no sacrifices to drivability or reliability. Introducing the CorkSport 72mm Throttle Body for 2007-2013 Mazdaspeed 3, 2006-2007 Mazdaspeed 6, and 2007-2012 Mazda CX-7.

Starting from the ground up means 100% brand new parts, no reworked or refurbished components anywhere.  

We start with an aluminum investment cast body that is made to our specific design specifications.

A flat faced throttle plate is added to gain a little bit of extra flow by avoiding the bump of a traditional round pivot shaft.

Finally, new electronics are added that are based upon OE logic to avoid any tuning and calibration issues.

To retain easy installation, we knew we had to keep the OE bolt pattern. With this, we wanted to maximize the throttle plate diameter for maximum flow. We ended up increasing from 60mm to 72mm. This may not sound like a huge increase, but the OE Throttle Body fits inside the CorkSport Throttle Body with plenty of room! The 72mm size also fits well with both 3” and 2.5” intercooler piping to fit almost any TMIC or FMIC setup. Finally, we did away with the OE gasket (which is too small anyway) and replaced it with a durable O-ring that will hold up to oil, gasoline, methanol, and other fueling options that it may come in contact with.


The CorkSport Throttle Body underwent extensive testing to ensure that it will not fail during daily use and to ensure it performs as well as we expect. The throttle plate underwent endurance testing to validate the D-shaped pivot can stand the test of time. During flow bench testing, we found that the CS flows about 150CFM (~33%) better than the OE throttle body when 75% open (accelerator pedal fully depressed).

Check out the graph below for the full data.

In daily driving testing, we noticed better throttle response with no CEL or choppiness. In power testing with a midsized turbo (~GT30 size) we found the throttle body caused faster spool, but when we moved to a big turbo, things got interesting. With a GT35R, the CorkSport Throttle Body caused 100-200RPM faster spooling and an increase in power. Check out the dyno graph down below to see the difference between the CS Throttle body (blue) and the OE throttle body (green).

Dyno stats for the Mazdaspeed 3 Throttle Body

Each throttle body ships with fresh stainless steel mounting hardware, a 3” stainless t-bolt clamp, and your choice of silicone. We have options for FMIC, Mazdaspeed 3 TMIC (which also works for you CX-7 guys), and Mazdaspeed 6 TMIC.

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! 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.

CorkSport Mazdaspeed Injector Seals
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 injector 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 build up around the injector and seal and really locks that sucker in there over time. Sometimes, a Mazdaspeed injector has to be sacrificed, as seen above. But, It’s amazing how much easier the proper tool can make the job.

Stainless steel Injector Seal

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

HOW TO USE:

  1. Take off the O-Rings 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 it backwards.
  4. Use your other hand to slide the hammer backward until it hits the lock nut on the back. Repeat until the stubborn injector finally breaks free.

Dear Mazda, I have a Wish List

Dear Mazda,

I want to let you know what’s on my wish-list so that if you ever happen to stumble upon our wonderful little world of CorkSport, you’ll see everything I’ve been dreaming of.

1.      New Mazdaspeed

While I personally prefer the Mazdaspeed3 hatchback look, I’d even be ok with a Mazdaspeed6 iteration. I like to have fun; I like to be pushed back in my seat by power and performance, and realistically I LIKE TO GO FAST. The newest generations of Mazda are missing some of these aspects, and I’ve been dreaming of their return!!

Now, don’t get me wrong, I like the Gen3 Mazda3. It’s a smooth ride, and we’re pretty stoked about what it can offer. However, our customers like to make power, N/A leaves us begging for more despite what HP we can squeeze out of the Mazda3.

So, Dear Mazda, Please bring back the Mazdaspeed!

2.      Mazda CX-3 with a turbo

Genuinely, I like the look of the CX3, I enjoy the size of the CX-3 and even find that it suits my ever changing lifestyle being a little higher off the ground. (For those who don’t, check out CorkSport’s lowering springs for the CX-3). It’s just flat out missing the power that comes with a turbo. It’s “get up and go” is … well… slow. This could, with the right improvements, be a great replacement for the Mazdaspeed3 for those of us waiting for the newest generation. Just please, please, can we get some more POWER?!

3.     Turbo Diesel Mazda 6

You gave it to everyone else!!! Why in the world would you leave us out?! You have to do ZERO redesigns; just getting it to the states is all I’m asking. The clean look of the Gen3 Mazda6 is something we like, but the power and improvements that come with the Turbo Diesel, I mean COME ON?! Just let us have a chance at it!

Heck, make that an AWD Mazda 6.

If you’re feeling generous, you could make it an AWD Turbo Diesel Mazda 6.

If we’re going THAT far, make it an AWD Turbo Diesel Mazda 6 wagon, because “I love me some hatchback!” that big booty look, and being able to fit all of the things… What’s not to love?!

It’s not a long list, and I realize that it’s selfish of me to ask, but I’m pretty sure I’m not the only one you would be making happy if you would just deliver on even ONE of these items.

Hopefully yours,

Kim@CorkSport

 

P.S Apple Carplay, and Android Auto… have been in the works for about 3 years, and you probably could have just hired a coder and completed a custom code in half the time… so we’re still waiting for that one too.

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!
