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.

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!
