Ive had a stock turbo, gt3071r, upgraded stock turbo and now the BNR S4 I would say I like this turbo the best. It makes the car have this attitude I love it and crazy fast!!!!!!!
Very tempting upgrade. I think there maybe an S3 or S4 in my speeds future.
+everythingdiy Can't wait to watch the install! All of your videos have been super helpful!
+everythingdiy DO it! I just got my S4 for $900! I am installing a couple weeks!
Hey Alan! Very nice vid, thanks for supporting MS community not only with parts, but with cool how-to's!!!
Keep it doing great job, my appreciations!
Nice vid. I prefer to pull the 2x 10mm bolts from the primary EGR instead of removing the exhaust manifold, but both methods have their benefits.
Sounds like you have installed one of these. I have an S4 ready to install and rather not remove the manifold. Any advise is appreciated. Thank you.
+Sal Mafi If you remove the EGR valve and the battery tray, you can install the turbo from the driver's side without taking the manifold off. I suggest installing an EGR blockoff instead of putting the EGR valve back on but it's up to you.
I would like to do that but I live in California. Smog laws are so strict here. Would disconnecting the valve have the same effect?
Just wanted to come back and thank you for this video.
I used this video and Corksport's instructions together to do my S4 install. I chose to remove and install through the intake side, via Battery and EGR removal. It's work getting the k04 out and more work getting the S4 in that way. But, it's done. 👌
Awesome! You're welcome! Enjoy the turbo!
You made that look so easy. I wish the speed 6 was as easy to get to everything as the 3, because I would have already done this, since my K04 has seen better days and barely makes any boost.
I am installing actually a Corksport turbo in my 2008 speed 3. I’m having some trouble getting to the first five downpipe bolts on top. But my question is do you absolutely need to get underneath the car to unbolt the turbo?
LOVE my BNR S3 on my 2010 Genpu. How does this stack up in terms of ultimate power it'll support, boost threshold, and transient response? The S3 will support 380whp before needing supplemental fueling, and some have pushed it really hard to over 420. If I WOT @ 3,000, I'm at 20+psi by 3,250, and transient response is excellent.
You say the S4 is capable of 400whp, but so is the S3, which is also more responsive. With the GT3076 compressor wheel on the S4, it'll obviously have a higher max flow rate. So would this be good to 450whp? 475whp (with supporting mods, of course)? If someone only wants 400, the S3 could be viable...
Numinous lol 😂 I like how you definitely know your stuff, you definitely ha e more knowledge in this bnr turbo then myself but I was able to follow you just fine and I still find it funny how no response was Given to your comment. Basically in sort... you outsmarted them and pushed harder on earlier model when they say they can only push 4 with the next step😂. It’s funny to me.
thanks for the video man, helped me a lot
Is it okay to drive a BNR STAGE I without a tune?? Is it basically just a stock replacement?
Drew L no, if you decide on going big turbo contact a e-tuner for a custom tune but first you would need a cobb accessport or versatuner for tuning capabilities. A great choice of turbo though, I’m thinking about it for my speed6 but it’s a little more difficult of an install due to the awd set up/transfer case being in the way of the install from the bottom.
you dont prime the lines or the turbo for this install? Jus run it dry and let the oil feed system lube it up as it goes?
Is 400whp w this turbo possible on 93 pump w/o meth injection with the proper tune and supporting mods?
Not really, and even if it is, you're going to be too close to any limits of that fueling which is dangerous. Pump gas really wasn't made to make a lot of power and shouldn't be treated as such. If you don't want meth injection, I suggest using a mixture of about 25-30% ethanol in your tank and you can stretch the limits of the turbo much easier and safer.
Edge Autosport can u you run this turbo on 91 not trying to push lots of horsepower kind of my turbo seals are done and need to replace turbo but at the same time prep for the future what do u need my car is stock to the bone if u can provide a list from edge auto sport I would appreciate it
Nice install! You guys ever going to get the Focus ST engine tear down video?
+Caleb Lanehart (RougeAngel) Thanks! We should be getting that video done soon!
i will get this bnr s4 ...i currently have a htp 4in intake...what size coupler will i need to use it with this turbo?
I would unplug the negative battery terminal when doing stuff like this just my 2 cents. Otherwise great video Edge!
+JD Davis Ha! We figured someone would say something about this and the truth is, your 100% right. We ended up taking it off halfway through install and not showing it in the video because of that. But you couldn't be more right.
+Edge Autosport Hah yea i saw at the end of the video you had it disconnected. Great now i dont know if i want a s4 or a corksport turbo.
+JD Davis S4, of course!!! ;)
great video
Hey Alan, I was wondering what kind of BOV you have or recommend since I prefer fully vent to atmosphere. But I'm scared because when manufacturer make it recirculating to intake it's for a reason. I just don't want to mess with air fuel ratios or mess anything up. What would you recommend for long life of a semi abused 2013 ms3..Thanks!
It's completely fine to run an atmospheric blowoff valve on the MS3. You're right, there is a reason for recirculating but it's not a big enough reason to resist your urge for a vented BOV. Go for it. The HKS is a great one, we've used it on one of our build and it's a very high quality valve that you don't have to adjust or maintain. The Tial Q is also very popular, you need to pick the right spring based on your vacuum reading. We recently put on a Go Fast Bits SV50 on our Focus ST and I like that one a lot but there aren't any bolt on options for that. You'd have to get a pipe custom flanged for that with the flange that comes with the valve. Let us know if you have any other questions. All 3 of the valves I mentioned are available through the site!
Thanks!
Edge Autosport . I guess my last question to you would be if with the turbo,intake, exhaust and down pipe would you need to run upgraded fuel pump internals. Or with your exact setup what's the max we can push before needing more fuel? This would be for daily use 80% of the time. Again I thank you for your knowledge and experience.
You would 100% need fuel pump upgraded at that point. There is no exact setup for when you need them. If you want to make over 275whp, I'd plan the upgrade before you go past that.
do you need to buy a smaller battery for the battery tray?
Yes, the battery tray used on this car doesn't allow for a full size battery. You'll need a smaller one.
luckily my downpipe is v band so when i take it out it will be so much easyer
I saw the dyno videos that showed in excess of 400 wheel torque with 24psi on the S4. Isin't that beyond what the stock internals can take? Did the dyno Mazdaspeed had a build engine with forged internals?
It's not beyond what the factory engine can do, but it depends. If it's tuned safely enough and you don't abuse the car too much, it can last a while. But it typically doesn't last as long as a stock car would. Just like any modified vehicle though, there isn't one answer about what something can or can't do.
How much would a shop normally charge to do a turbo swap like this?
Unfortunately, I can't really speak for a shop on what they would charge. You would have to contact who you have in mind and get a quote from them.
is it safe to drive the s4 without a tune
Hey Robby, sorry for the delay. No it is not safe.
Helll nah hahaha you’ll kill your car :)
But I like coolant spraying all over my face.
What is the coupler size?
Any plans to open up a edgeautosport shop in phx. az??????
what size was the coupler that u guys used ? and did the stock coupler fit where the turbo and intercooler meet .?
+11ufcfighter This car had a 3.5" HTP Intake and the BNR has a 3" compressor inlet. So, the coupler here was a 3.5" to 3.0" reducer. Whatever you have it needs to be 3.0" to whatever intake tube size you have. For the turbo to intercooler coupler, yes, the stock one fits and we actually used it in this car in the video.
+Edge Autosport oh ok thank u! and what size clamps would u guys use for a coupler that's straight 3 inch for the turbo to the intake?
+11ufcfighter Clamps are obviously not one diameter, but you just need to get a clamp that's advertised to fit a 3" pipe or make sure that the range is equally above and below the range of 3" so that it has good coverage for clamping down and loosening up.
Thought this was possible to do without removing the manifold?
It is possible if you remove the battery and if you delete the EGR. I can't quite remember how tricky it is to get in in there but you're right, it can be done.
Edge Autosport, Awesome. Thanks for the FAST reply. 👍 Taking this on soon.
Is this CARB legal?
I know this is old but I need s1 help
The HTP 3.5 fits the BNR S4 as well as the K04?
+arcade16 Definitely! All you need to do is get the correct coupler to mate the 3.5" pipe to whatever turbo you're running. The intake will fit with all stock location turbos, as long as you're using the appropriate couplers. If you ever switch turbos, all you need is a different coupler.
Where I can get that complete kit.

Is this BNR S4 Turbo reliable on a MS3 with stock internals? How much mm is the Turbo and how much whp is it good for?
+Devonte Murray It CAN be reliable to a point. It depends on how hard you are on your car, because any car fails from constant abuse at some point. You also need a tune that will promote reliability. It's similar to a GT3076 which has a 76mm compressor wheel and a 58mm turbine wheel. I don't know the exact specs though. It's definitely good for around 400-425whp while staying mostly efficient.
Edge Autosport Is the BNR S3 good for stock internals? I'm curious to know cause I might consider a MS3 in the near future.
+Devonte Murray I would really answer that the same way I did on the S4. They are both fine on stock internals if tuned properly and the engine hasn't been abused previously. As with any upgraded turbo car though, nothing is guaranteed.
+Devonte Murray If you're referring to the HPFP internals, you'll want to upgrade it.
***** What's HPFP?
Seriously.. “stage 4” is all you had to say about the turbo? Pretty vague if you ask me.
The turbo itself is called the BNR S4 Turbo, or in other words, Stage 4. It's just the name of the turbo.
Would it be any easier in a RHD MS3?
We've never worked on a RHD but I can't imagine a turbo install would be much different.
is ot okay if you have a kosmic returnline on a oem ko4
If it fits I'm sure it fine but I'm not sure that it actually does fit.
Edge Autosport well i just ordered it today fingers crossed. i would think if you can still use the oem return line it would fit np Thank you
the coupler is what 3 inch to 3 1/2 inch ?
I can't quite remember what intake we used in this video but the BNR S4 is 3.5" inlet, yes.
This looks wayyyy too easy. What am I missing?
Easy to some, not easy to others. If you have experience working on cars, it's really not that crazy of an install. Usually a 4-5 hour process for someone that really knows what they're doing. 6-7 hours for a guy that doesn't have a ton of Mazdaspeed or modding experience. This video is pretty complete to be honest!

i will get this bnr s4 ...i currently have a htp 4in intake...what size coupler will i need to use it with this turbo?
+Oscar Barrera Edit: You'll need a 3"-4" coupler
hi there edge auto sport first of all great detailed video. just wondering how long this took you to do the whole job. my turbo stuffed and am wanting a rough guideline thanks
Hey Bradley! I would say it's about a 6 hour job at the most if nothing goes wrong. It can be done faster but if you're not familiar with the installation, you should take your time doing it right. Let us know if you have any specific questions.
I really like your video and the way yo did the install,what would you recommend on a 2008 Mazdaspeed 3 turbo install im starting having problems with mine and i think is time to put a new one one problem is i dont know any shops who do this kind of job here in Phoenix Az.
Hey Polo! Thanks for the comment! There are a handful of good turbos available that are easy to install, including this one. It really just depends on your goals and preferences. The Garrett turbos are ball bearing so they will spool well for how big they are and much air they can flow. The BNR S3 and S4 are great turbos for being able to spool quickly and still maintain a decent level of top end airflow. The choice is yours. The good news is, we only sell good turbos on our website so you can't be steered a wrong direction through us. :) Let us know if you have any other specific questions. You can call or email us too! edgeautosport.com
Bnr S3 or S4 are the best choices 👌🏼
any idea how much power this car made?
