Best Turbo for Replacement any Suggestions?

[SharkZilla84]

Just to keep it simple and quick not to lead off topic.

I have a 2011 Ms3 with 50k miles still have warrenty on everything BUT the turbo :/....

I've been doing so much research to replaced my turbo(oil smell, white clouds and burning oil pretty quick). So Please don't ask me to! lol

Either a Corksport Turbo or a BNR stage 1 or 2.

I know i will have to get a HPFP and Accessport if i go either or on the upgrade but those will

have to come later within the month.

I am not expecting to get a lot of power since this is a daily but would love to get to 350 later in the future.

So what is the best possible route? as of right now I have the money to get either or.

thanks for the suggestions in advance and if im in the wrong thread.... My bad

I'm not sure a thread is needed for this decision. There's already so much info out there on bt's.

Having said that, you said you're thinking about the cs turbo, or s1/s2 but I'm pretty sure the cs is comparable to an s3. An s1 is just a better built k04 and the s2 is hardly on upgrade and will probably leave you wanting more rather soon.

Recently ppl have been having issues with their cs turbos. I wouldn't pick one up until those issues are resolved.

I say get an s3, it'll be great for a daily.

[SharkZilla84]

one of the main answers i been looking for...
Yea i have been reading threads on info for 2 weeks a lot of old threads though(mainly from 2008 to 2010) looking for the right answer up to date of 2016 before i make my purchase.

GTX2867 also good daily turbo. Falls in same category as cs and s3.

Noob question is it a bolt up?

One more question? What is the power difference in a BNR S1 an S2? would love to go with S3 but im not trying to get up there to race Corvettes lol
I live in Houston traffic is Hell better off with Torque than HP lol

[robbspeed]

One day when you have more bolt ons and you're ready to turn up the boost, 350 whp should be no problem.

For the forseeable future, an s3, hpfp, intake, test pipe, and tune(AP or versatune) would make for an awesome dd.

[OCspeed]

You're a long ways away from going bigger turbo if you are all stock. Get the necessary supporting mods first and then I say a BNR S3 will do the job

Yup you can get the gtx2867 as a bolt on kit from Edgeautosports.
I don't know much about s1 or s2 except that if you got one of them you will wish you had of gone bigger lol. GTX2867 and s3 will get you around 330-380 ish depending on fuel and tune. I would suggest getting in contact with someone from Edgeautosports and have them quote you a few different options including all necessary parts needed to safely go bt

yes a very long way actually only had the car for a year so it is ALL stock..i was gonna just go with the S2 and wait for a few weeks to get the HPFP and etc. not expecting high numbers just my daily with small upgrades you know lol

The bnr's and cs turbo are all drop in as far as I know. I think the garret's might require some minor mods to install and they are more expensive.

The s1 will achieve the same hp/tq as the k04. The s2 flows like another 2 lbs/air per minute. Like i said before, it's hardly an upgrade.

You don't even have to be fully bolted for an s3 or something comparable unless you're looking to really push it.

Definitely thanks for the info on that, you are right for the S1 and S2, im more an likely just to grab the S2... im in my 30s loving his Ms3 a little more power is just fine, dont think my daughter would like godzilla in my engine bay lol

GTX was a drop in for me. I added a new dp during instal, but would have worked with oem.

[SharkZilla84]

when you mean i dont have to be fully bolt on...you mean just like a HPFP and ACP is just fine right?

I also made this thread for pple who are stock in this situation in 2016 lol

[robbspeed]

OK just know your gunna need a tune right after the install, so be thinking about an etuner also.

Yes, hpfp and AP/versatune are a definite. You can get away with just an intake and a test pipe as your primary flow mods. The car will be fast as shit compared to stock.

Thanks, thought I remembered reading they weren't quite a drop in replacement. It is the better turbo if performance is the most important factor and money isn't an issue.

[Polish_Eagle]

I have a GTX3067R and it was a drop in turbo. I personally love the performance of it as it has room in the upper power band but still spools decently fast.

[Omega]

If you're looking for 350whp later why not just buy another low mileage k04 if you're happy? Even if you had 4 more K04's used it'd be cheaper than any new turbo options and get you pretty darn close on E.

If you're going to upgrade at least go for a bnrs3 with supporting mods.

[MSP6]

BNR Stage 1 = a K04 in terms of power, but it won;t smoke or shit the bed

BNR Stage 2 will give you a small bump in power, but you might still get your ass handed to you by a speed running E85

BNR Stage 3 will give you good power, is time tested and only costs a little bit more than an S1 or S2. Drive ability will be the same, reliability will be the same but IF you decide you want more power later it will be achievable

GT or GTX 28 will put you in the same place both power and drive ability wise as the S3 but will cost you a LOT more.

Corksport is the same place as well in terms of drive ability, response and power as the S3 and GT/GTX 28 but they have had some reliability issues that are still being addressed.


I really so no benefit to going anything other than the S3, in my opinion. Its the best combination of response, reliability, power etc.

The BNR S3, CS Turbo and GTX28 turbos are all comparable. Each one of those turbos are drop ins, proven to work well with the DISI motor and can hit 350HP. The real difference is most likely price and even that they're probably similar.

If you're asking what we mean by fully bolted, I think you have a little more research to do because there is no way you've been reading build threads and think by simply throwing on one of those turbos with just internals and a tune is going to net you 350HP. At the very least I would get an larger than stock intake and intercooler upgrade. Add a RMM and TP/RP/DP in there as well. OCC and/or EGR delete wouldn't hurt. Aux fueling, whether it be meth or corn, is a decent consideration as well provided corn is accessible or if you want to go the meth kit route. So again, if your expectation was that you could just upgrade the turbo, get internals and a tune and expect to magically make 350HP, you're going to be disappointed.

It's good that you decided on a goal in terms of power which helps narrow the turbo field down but it sounds like you still have a little more to consider than just the turbo.

[Jeff23spl]

Looking for S1 or S2, you can also look at replacement CHRA for the K04 too. If the goal is only stopping smoke, the latest can be a better cost effective option.

But going slightly bigger is to my opinion the best option. You would need the AP and HPFP at time of the turbo install. (not later) i may be wrong but ''bolt on'' means you can bolt it right there without much changes but i don't think any of them would work fine with a stock tune. Especially if the stock tune make it pass over the stock parameters, you would need pump internal more than anyone else.
Usually peoples climb the stages with the k04 and have most of the supporting mods before changing the turbo.

Larger turbo will spin slower for the same flow, bearing/bushing will last longer
Larger turbo with larger hotside makes the same HP at lower boost and lower BAT(better for the engine)
Upgraded turbo with special comp wheel could be more efficient and just work better (I don't know about S3 but all GTX...)
Larger turbo will spool later, it may sound bad but one thing hurting our engine is the low rpm overboost...Having one that spool slightly later just save it by itself. The lag of a really large turbo may be bad but a 67/71mm comp wheel isn't that bad...

Downside: It is hard to keep a larger turbo from making more power....you can tune it down but soon or later you will want it to make more and it start to get heavier on everything.

You can't use garrett as direct bolt on because of mazda special mounting flange but some sell ATP kit with a Mazdaspeed designed hotside to make them ''bolt on'' like Edge. It comes with coolant and oil return fitting to bolt it up easily but you would need to check for inlet pipe size. You will need a new TIH with it and a longer silicone hose between turbo and IC...(Don't remember if the silicone coupler comes in the kit or not)
CS will work with stock piping instead but it pack larger wheel inside a very small package so i wonder about the A/R vs high rpm efficiency...Same for the S3 turbine on the stock hosing but i don't know if the 71mm cold side need a larger TIH for it or not?

Lol i am not trying to race anybody, doesn't matter what HP you are pushing... there is always someone that just going dominate lol..
I am working on my career goals so i am always at work, free on the weekends though
just need something at the moment so i can get back and forth for work... Im buying the turbo monday and 2 weeks later the rest of the stuff comes along...

[MSP6]

If you are being honest, and aren't a dummy, you can install any of these turbos and drive as normal with no tune until your AP and internals arrive IF you drive like a normal damn person and stay away from full throttle etc.

BNR S3 and be done with it.

sarcasm?

that's like a chick getting her boobs done and then not titty fucking me with those DDs. No way you pull a turbo to put a bigger(ish) turbo in and just drive around at half throttle.

i had a BNR S2 it was a pretty damn good turbo i made close to 370hp on a fully built ported maxed out tune.

Not sarcasm. Directed towards his comment of "I'm buying the turbo monday and 2 weeks later the rest of the stuff comes along..."

Absolutely no reason you can't install a BNR S1, 2, 3, Corkport, GT/GTx 28 and put-put around for 2 weeks or so until your tuning solution and internals arrive in the mail. Other post edited to clarify for future readers.

Wasnt going to install the turbo until the rest of the package arrive dont like driving my girls car to work but if its a have to then ill definitely wait....i know the HPFP and ACPort is a must..so ill install the turbo when that arrives...

ah, why do double the work when you can just wait 2 more weeks and do it all at once and not have to worry about blowing the car up while you wait? But I get what you're saying

[SHADY1]

You have many good choices at this point just as why? Bone stock!!! just get a rebuilt k04, have the turbine housing ported, and put Billet compressor wheel on it. Put the reset of the money you save and do supporting mods like AP, intake, cat back, downpipe, HPFP and Internals.

And at that point you will be ready to get away from small frame turbos. I'm not saying BNR or the GT28xx series turbos are junk because they are not.

Just do the research and be smart about the mode path you take. Zoom Zoom Boom is not a nice path to take, nor is doing twice!

You are right actually could get it rebuild and get the HPFP and AcPort faster...
As the Mazda dealer was saying I have a leak (barely had any oil in the car) but I don't see jack squat dripping....just came from outside... 3rd Coast turbo said just to get a Oil catch can but I read its just a hit or miss...if y'all have any insight which I know y'all do cause this is the best forum I've seen

[SHADY1]

Catch Can will always be a plus for you daily driver. Oil consumption on the other hand will not be corrected with a Catch Can. Looking for drips in the driveway is a good first start however oil could be pooling in the bottom engine cover, so jack you car up and pull it off to verify.

Note that the K04 is a busing turbo, generally speaking 50k between rebuilds are needed and can expiain oil usage. These are relatively good turbos and you should be able to find one on ebay cheap. when I had my stocker I had a rebuild on the shelf for quick exchange.

Note that faulty PCV or EGR could also explain oil usage but normally you will throw a code at some point if these are going bad.

[SharkZilla84]

Yeah I was thinking if it was in the exhaust internals...I don't get any oil drips nothing at all....yeah so speaking about the 50k mileage rebuild...my car is exactly at 50k miles

[SHADY1]

Yea , pull you TIH and see if you have shaft play at you turbo (which you will). Ten pull you TMIC and see if you have oil at Turbo inlet. White smoke will be an indicator when you are getting into the throttle. Have one of your friends follow you with and take a video of you getting into the boost.

Note that someone may of already done a turbo rebuild on this car. If so the oil return pipe is a problematic area and most newbs will not get this area seal tight. The issue with this is that you may not see drips under the card as it will pool in the lower engine cover. When you drive the car oil will spill over and get on you exhaust and car under carriage. The only way to tell for sure is pull the lower cover and take a look. Sometimes you will be able to smell faint oil burn off when you get out or when AC is in rec mode.

I have not been on this forum much or posted a bunch. I'm more of a troll in that regard. I am going to become a VIP today and I have a kit you may want to try. (Stk K04 newly rebuild, Ported exhaust Housing, and billet compressor wheel, CS TIH, Injen CAI, and all rubber needed. I have it posted on ebay also.

This will not get you to the magic ooh my god this car is fast feeling most of us want. But with turbo back exhaust and HPFP upgrade I got 320 whp at 400'ish ft-lb in optimal driving condition 80 degrees or so.

[Polish_Eagle]

I personally love the GTX3067R as it has lots of room up top and spools pretty damn fast!

[rocknrolla47]

What about a bnrs4 ? Have you thought about that turbo ?

[Puman_chu]

Whatever bt you get just don't be a retard and not get brakes to go with it.

Has anyone installed a mamba turbo gtx 2976R
I heard some good reviews from the skyline and wrx forums.
Apparently they use this turbos in Japan to drift....
