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! 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.

CorkSport BIG Turbo for the Mazdaspeed & CX-7

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 Mazdaspeed 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 turbo 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 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!

Top 5 Tips for Family Roadtrips in your Mazda

Dear Car Guy,

Hope this finds you well and enjoying the switch in seasons.

Wanted to give a shout-out to all of you Car Guy’s that are also Family Guy’s! You’re THAT guy that keeps his car clean regardless of the amount of french fries and jelly belly’s that are left on the seat after you’ve removed the car seat. You’re also the guy that gets to load everyone in your AWESOME ride because it’s highly likely that your wife hasn’t cleaned out her car in what seems like decades. So the dog, the kids and the luggage all get to replace your sound system in the back for the weekend as you go off to visit family for the upcoming holidays.

Here are some tips, since I know you’re always into life-hacks that keep your car in pristine condition, and to make your extended car rides a little bit more tolerable with family!

#1. Lay down plastic. NoCar Wrap Kidding!

Grab some painter’s plastic and lay it over your seats with holes for the seatbelts, and you’re less likely for spills to stain and cause a permanent mess. Not to mention when you’re done with the trip, be it out trick-or-treating, or heading to be with family for the weekend, you can just scoop up the dirt, broken crayons, half eaten suckers and candy wrappers all at once. Better yet, if you can convince the screaming kids and wife, don’t let anyone eat in the car 😉 If you have to… Here’s an idea: https://diningwithalice.com/twin-cities-live/travel-snacks-for-kids/

Candy Organizer

#2. Travel the road less traveled.

Those winding twisting, exciting roads will rock the kids and screaming tots to sleep (if you’re lucky, the wife too!). Leaving You with nothing but the wheel, the road, and some thinking time. (Please be careful with these roads as the weather gets worse). I love this way, even if it takes 20 minutes longer, it’s worth it for the silence and fun.

#3. Use your coats (full sized adults) and zip them over the front seats.

Keeping the little feet from leaving foot prints and stains on the back of your seats. Or use something like this: Seatback Protector

Seat Cover

#4. Put a full size towel, in a plastic bag and leave it in the wheel well of your spare tire.

This would be perfect for the unexpected messes or dogs that run off into the lake. We all know that someone will have an accident, spill a drink, forget a favorite blanket, or will inevitably fall into the only mud puddle seen for miles. Be prepared for our furry friends it always seems like it was on purpose!

#5. Embrace the show tunes, it’s highly likely your kids are into some form of musical torture.

If you just embrace it and sing along they’re less likely to want to continue with that soundtrack. What better than the voice of Dad over the “Frozen” theme song to annoy the kids, or a great rendition of Miley Cyrus screamed in your best falsetto. Unless you’re into the same song on repeat….

HIMYM

Don’t worry, we’ve taken these ideas from the Dad’s here, and they really work. So find a way to “Let it go”, and yet still protect your favorite ‘baby’ from your beloved brood.

Stay Safe, Stay happy, and Enjoy the ride!!

Mazdaspeed 3 Coming in 2017 with AWD!

850084604902340741

UPDATE: Masahiro Moro, president of Mazda USA, called the Mazdaspeed 3 “childish” in execution. What does that mean for the future of the Mazdaspeed model? Find out.

According to Ryan Beene at Autonews.com the next Mazdaspeed is planned for 2017. At first glance we might assume that this is purely more rumors, but upon further inspection we see that there might be cause to believe him.

Why?

First of all, Ryan Beene has been vouched for by several other automotive sites and journalists. Over at thetruthaboutcars.com they state “Having known Beene for a number of years, I can say that his information is to be trusted more than the typical buff book “anonymous sources” accompanied by some fanciful colored pencil sketch or computer rendering.” Jalopnik.com also states: “Automotive News’ Ryan Beene, who has covered Mazda in depth, is rather reliable. This is a good thing.”

So apparently we should listen. We also see some of the first reasonable explanations for AWD and a Turbo. As we have discussed previously, the new Mazdaspeed will most likely share the AWD from the CX5 platform. See the article here: //corksport.com/blog/will-there-be-a-new-mazdaspeed-3-with-all-wheel-drive/ where we also happen to quote Takeo Mariuchi, the program deputy manager as saying “from a technical point of view it’s not difficult to install a four wheel drive system”. We also showed some interesting photos showing the rear of the CX5 and 2014 Mazda 3 that appeared as though it would be rather simple to add the AWD.

Nonetheless we put our stamp of approval on this statement.

The second thing that he brings up, that we can stand behind, is the fact that he believes the engine will be the same as the one used in the CX-9 launching that year. This would not surprise  us at all since it would help shave cost, and engineering work on Mazda’s behalf.

There is a lot more info in the article, so feel free to read the full article here: https://www.autonews.com/article/20140825/OEM04/308259975/mazda-making-big-changes-fast

 

I’ll summarize the rest of his interesting points here otherwise:

COrkSport-Chris-Childress-Mazdaspeed-3-Mazda3-Mazdaspeed3-Rumor-2017-Release

Mazda 2: Redesigned Mazda 2 production starts in November and he expects a sportier Mazda2 with a modified intake and exhaust as an option.

Mazda 5: This will get killed off by 2015 due to lack of interest.

Mazda 6: An interior redesign for 2016, new center console, smaller dash that sits lower. Similar to the Mazda3.

Mx-5 Miata: Debuts in one week. Will have a SkyActiv 2.0L liter engine (no word of a turbo). More exciting though is the news that Mazda is planning a fastback-style hardtop version.

Rotary RX-7 or Rx-9: They are still working on it, should be 2 seats, not 4. No word on when.

CX-3: This should go on sale next June. Built on the same platform as the Mazda2.

CX-5: Fresh interior for 2016 and new front and headlights.

CX-9: Redesign for 2017 with new KODO language. Turbo Engine 2.5L that will be the same as the Mazdaspeed 3.

 

Of course, Ryan still doesn’t quote any sources or give any proof, but we definitely are willing to believe all that he says!
