Important Notes

*Our Mazdaspeed replacement turbocharger requires supporting parts, fueling and tuning to reach 250-450 horsepower.

The CorkSport turbocharger does require the use of an aftermarket tune with Versatune or Cobb Accessport. Engine damage can occur without the proper tune and the installation of this turbo.

How To Install Your Mazdaspeed Turbo Upgrade

It will take you 4 hours (240 minutes) to install your turbo with our instructions.


Install time                  4/5 Difficulty               1-year warranty       No CEL

Replaced my K04 with thisturbo and so far so good im on my second revision of my custom tune and its already way faster than my maxed out k04 tune. Pulls till redline, sound really nice and is a direct replacement.


P.S. add 2 more hours to install time for MS6 owners because that car is just a cramped inconvenient nightmare to work on.
CorkSport definitely did their homework with this one. Swapped the K04 for this with a built bottom end. This unit is more than enough to max the stock fuel system with internal. I ran 24lbs on E30 mix all day long. Logged 390 grams / second on the big end. Has excellent spool and flows until you want to shift. Very very smooth unit with highly responsive wastegate. Would recommend the other supporting mods to get max potential. The venerable TD05H CHRA paired with the 18g billet wheel and 9cm^2 hotside is a wonderful combo on the MZR. Very very happy with my decision.
Amazing turbo!!!! The spool is quick and powerful! Install was direct replacement of the k04! I'm very happy with my purchase
The Corksport turbo is a great replacement choice for your k04 if you have suffered from a smoky or blown turbo, or just want more reliable power. My turbos blades had been damaged and were making a screaming noise so I needed to replace that.

Corksports turbo feels very much like the k04 but with more kick in the upper middle RPMs. On my fully bolted 2007 Speed3 I am pushing 23psi making 330whp and 350wtq on 94 pump gas. The turbo definitely has more to give and I can easily see it running more boost reliably.

The instructions provided by CS are very detailed with great pictures, and are my go to source for anytime I need to take something apart on my car. I attempted the install myself but had to take the car to my mechanic as the downpipe I have (cpe) had gotten the best of me. This turbo was actually his second CS turbo install that week!

So far I have put 2500km on the turbo and have had no issues. Of course that is not a long time for something to be on a car but it has definitely been an abusive 2500km. Thank you Corksport for the wonderful product and your great customer service!
Hi. I have a 09 mazda 6 mps completely bone stock. Im very interested in purchasing this turbo for my car. My q is, do i have to change internal components (pistons, conrods) to run this turbo effectively? Will this turbo kill the lifespan of my engine internals? Thanks
just installed the corksport turbo,3"intake,and corksport boost controller and just came back from tpg tuning in pa all i can say is wow!! I made 329whp and 352 torque on 20psi. (dont have the 3 bar maf sensor yet would of gone more) this turbo is so much smother than the junk k04 i am extremely happy with my purchase and would recommend this turbo to anyone
perfect alternative to the stock paper weight . dont let the size of this turbo fool you it builds to about 15 pounds really smooth then gets violent to 27 pounds fitment was perfect
I needed to change a smoking stock turbo and decided on this bad boy. I honestly chose it because it was a direct replacement and the price was perfect.

As others have stated, it spools for days and pulls like a pack of rabid dogs gunning for the finish line at the Iditarod.



Had this installed and dyno'd. Gotta say it is a top notch turbo and turned my car into a beast. It spools a bit later than the ko4 but the spool doesn't stop. Plus it whistles like a diesels turbo when spooling. Well worth the money especially since it really does drop right in with out issues. Time for a rear motor mount to get rid of the added torque steer.

I see in your white paper you take a fair amount of time to describe Compressor maps, Do you have available Compressor maps for the Stock turbo compared to your drop in turbo? I am sure more potential buyers than I would like to see them. Might be something to add to the white paper and point out the differences, both positive and if any negative, or compromises for the add volume of air. Thanks in advance

I've bought and installed this turbo on my car. I'm in the process of getting it tuned too. I've noticed that I have not been hitting the tuner's target psi. During the install me and a buddy got confused on if we needed to keep the restictor pill if I was going to use the greddy ebc(running bleed setup) and decided to replace the hose with the pill. Is that why I'm not seeing what I should and if so, how do I get a replacement?

With all things being equal whether it be a bone stock speed3 or a fully bolted speed3, what would be the actual power difference be, number or % wise between this turbo and the stock ko4? I havn't seen any dyno before and afters from anyone on any site yet regarding this turbo. I only ask because I am fixing to buy a turbo upgrade and right when I was fixing to make the purchase I heard of the CS turbo coming out. I personally am as fully bolted as can be with all parts being bought from yall =). I know if I buy this turbo which I will blindly most likely because I love yalls commitment to yalls costumers. I just want to know what to be expecting when i give yall my 1000$ =)
