Newb question about BNR S3

[ddevil]

Ok, so I've spent hours searching trying to answer all of my questions and trying to figure out the right questions to ask. I'm having the Mazda dealer put in a new motor and rather than replace the turbo with the shitty K04 I decided to get the BNR S3. What I don't know is what else I need if I don't plan on tuning it yet. I did order a larger inlet but other than that everything else is stock. If I'm leaving the BNR at the stock 14 psi for now can I just stick with the stock EBCS for now? Do I really need the Angel at all or have to worry about overboost for now? Should it just bolt up and run fine or will it run like shit without out at least some kind of tune? If a tune is required I have my doubt's whether the dealership is going to be able to do that or what. Any responses are greatly appreciated as I've been trying to figure a this out for a week now. As a side note I'm thinking about getting a rear motor mount while I'm having all of this done. Anything to reduce the terrible wheel hop and torque steer.

No, you didn't spend hours searching.

Keep in mind I had no idea what any of these words meant a week ago. So yes I have spent hours just trying to go from 0% to like %10 knowing what I'm talking about.

[dereeek]

you need the whole fuel pump thingy.

start with basic mods, then as you progress on this platform with knowledge you should put the BNR on.

I went with the BNR because the only other option is another K04. I figured I might as well spend my money on something that I'll have less problems from.

Obviously if the op is having the dealer replace an engine he has limited knowledge. I will say that having them install the bnr s3 without tuning or supporting mods is going to make for another engine being needed in a hurry. What happened to your old engine?

Do you have fuel pump internals? Running a catless downpipe?

Nope, all stock. I haven't seen anything mentioned about the fuel pump in relation to the BNR. Now I'm really starting to think I should have just gotten the stage 1 or just another K04.

[He Hate Me]

The BNR is more efficient at 14 PSI than a K04 is at 14 PSI.

Get a tune, save your motor...

[ddevil]

Would the dealer be capable of a tune? I haven't gotten to the point of researching tuning yet since I didn't know if I'd need one. My concern is that they won't be able to but I don't have a K04 for them to put in it for now.

The only thing the dealer can do is flash the ecu with the factory tune, they can't do custom maps made for different than oe turbo

[He Hate Me]

There's quite a few tuners on this forum that know what they are doing.

To have a tune on your car you need a Cobb Accessport V2 or V3 doesn't matter. A dealer is not capable of a tune. You will need to contact one of the tuners on here for the best results. Stratified, Freektune, or Nishan to name a few. This will run you about $200 but the tune is tailored to your car.

[ddevil]

Sounds like I probably should have just went with the K04 again. If I really need to spend $600 for the Accessport then I don't think it's going to work out with the BNR.

[memin]

you can get a Accessport V2 for$ 250-300.you just have to look around on internet.

[biggman026]

The BNR S3 is the turbo this car should have come with from the factory

[nilashish]

you need at least an AP and fuel pump internals and a custom tune...have the dealer put in the K04. Do your research and then swap the turbo yourself.

[Thepedigree13]

Cobb AP is just the tip of the iceberg.....you would need HPFP internals $350, at least a downpipe $300 or more, and a tune $200.

Plus personally I would get at least the RMM as far as non-performance mods go....

Sheesh....good luck when the savages on the forum see your original post. Go ahead and start lubing your anus now.

[ddevil]

Yeah, I was really dreading making this post because I knew some of the replies I would get but I was having too hard of a time trying to figure things out on my own for the past week. I wish I would have made it sooner though because now I'm gonna have to pay to have the turbo and inlet shipped back on top of the original shipping costs. I'm definitely not ready to start tuning to this level and don't have the money for all the extra things I didn't know I'd need. I probably won't do much with it until the K04 I'm gonna have to get needs replaced again. Unless anyone has any other ideas that's what I'm gonna go with. I really appreciate the helpful replies because otherwise I probably would have made a big mistake just dropping the BNR in there.

[Code Monkey]

LOL, wtf, have a BNR installed, buy a used AP v2 on the cheap, an EBCS, swap the fuel pump internals, get a mild tune, and enjoy the car.

[ddevil]

Am I risking anything by having the BNR installed without a tune for a brief period of time before a tune? My main concern is that the dealer isn't going to be easy on it pre-tune. If I could get by with a V2, GS EBCS, and fuel pump then I might still do it. I was originally looking at the full cost of a fuel pump but the upgraded internals are about half the price. So I'd be looking at almost another $1000.

[Code Monkey]

Tell them not to boost the shit out of the turbo and granny the car until you get a proper base tune.

[mxlplx71]

Even with a k04, you need the rmm.
The accessport should be considered a should buy also.
The hpfp internals are needed when opening the flow up, ie.exhaust turbo ext.
The etune is just smart, to get a good safe tune for mods. No zzb
You can have a safe daily mid 13 second car.
With all that, a bnrS3 and downpipe= low 13 to mid 12s. Safely.

[ddevil]

My original goal was just to have a better more reliable turbo for now. I'm not worried about numbers at the moment. It basically sounds like about another $1000 than what I planned to stick with the BNR. I definitely won't be able to afford a downpipe for now though on top of everything else.

[mxlplx71]

Not required, eBay ones work and almost all those parts can be found used in the for sale section cheaper.

[ddevil]

Is a different EBCS required or would the stock be fine for now?

[mxlplx71]

I think it can be made to work. I didn't. I cant search while on my phone.

[Thepedigree13]

I'm confused. Did the new motor you're swapping in come with a k04? If so I would hold on to the bnr, and start your mods with AP, AT Internals, and RMM. Enjoy the car and slowly get all you're supporting mods as you can afford them.

Then when you have what you need you would have enjoyed the k04 and the progress you've made.

When your mods/funds permit you can then install the bnr that you held onto......and probably sensually caressed for several montes.

That's what I would do.

[Ozynigma]

Why don't you go for the BNR S1?

[Johnasaurus]

All those hours of searching and he still has basic questions.....

[SpeedRebirth]

Guys, you are looking at this the wrong way. His current goal is not increase in power. His goal is a non-smoking turbo! So he actually made the right choice with the turbo!
You can get it tuned to have just about the same power as a k04, which means you dont need HPFP upgrade FOR NOW!

Do this:
1) Buy a used AP V2 for $300 tops!
2) Buy a Freek OTS Plus Map for $75: Freektune - Mazdaspeed3/6 Freek OTS plus map
3) Install turbo
4) Drive out the dealers door, park it and install AP + flash the tune
5) Win win!


If you want to turn up the boost later you WILL need HPFP Internals. But with close to stock power it's not required!

Sidenote: You might need a small 2 - 2,5" coupler between intake and turbo since the BNR inlet in slightly bigger than stock.

I actually have a 2.5" inlet on the way. Would that map still be fine?

I had to pay $450 for a used AP because I don't really have time to wait for one to pop up for $300. I also order the JBR 88a RRM and already had a HTP 2.5" turbo inlet on the way. Since I'll now have the AP I'm debating whether to keep everything I already have or send the S3 and inlet back and just go with the S1. If I go with the S3 then I'll definitely want to try and get a map loaded before the dealer starts up the car. I think I can get by with the S1 and then load a map shortly after I get the car back.

[Turbo_Steve]

I wouldn't trust the mechanics at the dealer to stay out of boost. They are going to have to test drive it after the motor install. Those guys typically are just certified parts changers. Not many are competent when it comes to performance. If you go this route make sure you talk directly to the mechanic doing the install and tell him not to get into boost and why. Use words like "it needs to be tuned for the turbo or you will blow shit up"

[maddocx240]

Send the s3 back and get an s1. Your not looking for more power it seems, so you don't have to worry about all this other stuff with tuning and such. I think that's your best bet, cause you obviously were a little impulsive. That's just my advice to you. That way you can drive your car and go home, good luck.

When I installed my BNR, I had Lex at Stratified tune me. He recommended a Boost Dial with the stock ECBS vs. a 3-port. I don't know if it will be necessary at stock boost levels. I would suggest talking to a tuner directly to be sure.

I already had an intake/TIP, DP, and HPFP, TMIC, and AP when I put the BNR on. Of that list, the AP for monitoring and tweaking the tune is the only thing I would consider necessary for a safe install. You won't be able to use the turbo to it's full potential without full supporting mods, but if you're even considering going big in the future, you may as well do it now. The S3 is about the same price as a new K04. The only extra expense will be the AP, which you really need anyway, and, possibly, an ECBS or Boost Dial.

Do you mean a new TIP? As long as you keep the stock size MAF, you should be fine. If I had it to do over again, I would skip the stock size SRI/TIP and go straight to a 3" or larger. Keep the stock stuff for now, spend the money on an AP, then go big MAF after you get an upgraded HPFP

[ArmanRus]

You could have donated $25 to the site and snagged the one for sale right now for $330. And then have access to the shop manuals and many other good things. Good luck with everything.

Well shit, I didn't even think to look there.

[ddevil]

Justin at Freektune was really helpful. He doesn't think it's a good idea to do the S3 without the HPFP internals even with the tune. I'm just gonna go with the S1 on the stock map for now and then get the OTS map shortly after.

[torquemaniac]

I dont see why the S3 is not a good idea with a tune (without the HPFP upgrade)?

With a tune you can limit load and be safe...then when the cash comes in, buy the HPFP upgrade...

[stockms3]

How many miles on the current turbo?
Was it smoking?

Maybe you could just use that k04 for now? Once you want to mod and have the money start with fuel pump and accessport.

[igve2shtz]

To the OP: Congratulations on making it this far ...

I am in a similar boat as you, and have spent months (seriously) on this forum trying to determine everything required to run the BNRs3 safely. Keep reading. There is ALOT of information on this forum once you get past the trollers. It is a great place to be.

Congratulations on your first modifications, and welcome to the darkside. Good luck with the BNRs1. Any of the aforementioned E-tuners can help you out tremendously.
