BNR stage2

[Jasper_3MPS]

so iam looking to get a BNR stage2 turbo but Bryan told me that i would have to remove my stock boost solenoid.

who has the stage 2 BNR and what solenoid do you guys use. i really want a bigger turbo that spools better but dont want to go whit ATP-2871

so the BNR is just what i need.

Any advice on this mater...

[jracer]

You only have to move it to the firewall I think.. Just move the location ...

[Jasper_3MPS]

think or know for sure cause the stage 2 actuator looks really different from the stage 1 actuator...

from what i understand from bryan is that i have to replace it...

[Jasper_3MPS]

Just ordered the Stage2 BNR from bryan it will have to the stock actuator on it so i can still use the stock boost solenoid so 1st and 2nd gear will still have less boost. so i will not be burning my tyres to smoke that much in 1st and 2nd

i will make a complete "How to" on the install of the turbo!

will still take a month for ill have the turbo in my hands cause the freaking customs waits so freaking long!

ill keep you guys updated

[CyA Sp33d]

Keep us updated! I'm looking to either upgrade to the BNR Stage 1 or the Stage 2 turbo. However I am not completely positive.

What was the issue with not getting a new boost controller? You could get the grimspeed that is plug and play or even a perrin. You are going to need a tune anyways so might was well get rid of the crappy stocker and get better turbo response.

I know a lot of guys are having issues tuning wth the Grimspeed Mazda EBC. I have a brand new one still in the box.

[xcoldricex]

why didn't you get the upgraded actuator? what's the point of upgrading a turbo if you don't want it to hold boost up top? the stock actuator has difficulty holding consistent boost above 15psi @ 5.5k and above...

there are many people running upgraded actuators with the stock solenoid... myself included.

[Jasper_3MPS]

for one it could hit the firewall because of the large compressor housing...

and second the stock one hooks up to the ECU and keeps the boost down in 1st and 2nd gear...

if you go whit an upgraded actuator you have to delete the solinoid and i just dont want to do that rather have the ECU help me to save my car and.

i dont have any upgrade internals on my engine so whit this turbo i can run lower boost and get more HP iam only looking for around 350HP at the crank and just a really smooth tune. not going for a top HP tune just a really good smooth ride that will keep my car zoomzoomPSHHHHHHH.

maybe this is more like a stage 1.5 and not a stage2

but the larger compresor house and the larger compressor intake will mean less heat from compresion at lower boost levels and more flow... and ofcourse NO SMOKE. Oil burn will also offset your O2 sensors in the exhaust so keeping oil out of your O2 sensor is also a nice thing when tuning the car no KR and strange AFR. the 3 MPS ECU does work different than the US Speed3.

but we will see what the car will do on the dyno iam getting a befor dyno and afterdyno

so... lets hope i can be the fastest 3 MPS in the netherlands and maybe even faster than the German 3 MPS

[xcoldricex]

i just told you that i was running an upgraded actuator with the stock boost solenoid. there are plenty of others that are as well. you DO NOT have to delete the solenoid. but you will have to tune your car. if you're going through the trouble of upgrading the turbo, you should get the upgraded actuator for reasons i stated above. if you're concerned about using the stock solenoid, then just pay the $100 or whatever it is for the perrin.

also, if you're tuning with the AP( not sure if it's supported over there) you can control boost in 1-2 with your tune. also i think the 1-2 boost cut is more for traction than saving your car from blowing up...

[DSIT995]

I think what bryan was saying was its easier to just disconnect the EBCS and run off the WG pressure b/c the actuator has a 17lbs spring in it. Kinda like the "BT" guys running just spring pressure off there EWG

Also I have to install mine (BNR 2) very soon, since my K04 has started smoking like a banshee. Definantly a seals prob

This is news to us. I know we've had a bunch of good feedback from our bcs and tuning. I know a couple guys that didnt have it hooked correct had some issues but once it was hooked up correctly the issues were solved.

beaner stage 2. Nah, thats my car

[xcoldricex]

i think the beaner stage 3 is the only worthwhile turbo to upgrade to.

I hope you're right as I'd love to use it (Since I've already bought it) lol

i thought a bunch of people in the GB thread had troubles with it. maybe it was just because they weren't hooked up correctly though. i know fobio had a lot of issues getting it to work with the upgraded wga, but i think he got it sorted out.

[Jasper_3MPS]

i got my BNR Stage2 turbo in! will wright a how to install when its installed. and what you need.

this is a stage2 BNR whit the standart wastedgate actuator. i wanted to keep the car to stock as much as possible so running of the stock boost solenoid.

[xcoldricex]

i still think it's stupid to run the stock wga. why upgrade the turbo in the first place if you're going to have trouble running 18-19psi with that shitty wga?

[Jasper_3MPS]

Originally Posted by xcoldricex i still think it's stupid to run the stock wga. why upgrade the turbo in the first place if you're going to have trouble running 18-19psi with that shitty wga?

cause i dont want to run over 18PSI cause this turbo flows more air so dont need that much boost and than i can always upgrade it later if it doesn't work that good but ill stick whit this setup for now...

[b00b00]

I can put that on my key chain

[cld12pk2go]

What makes you think the stock wga cannot hold over 18-19 PSI? It is holding 21-22 PSI for me with more backpressure than a BNR stage II will have.

[aaronc7]

im out the game at this point but Im curious to see what these will do!

[xcoldricex]

many people including myself cannot hold 18psi to redline with the stock wga, which is one reason why forge/ptp sell wga upgrades.

[Ms3speed]

So how would I hook this up? would I still run my Grimmspeed or not and I am running it in 2port mode now just like stock, would I have to switch it to 3 port or just take it out?

I hope you realize that the stage 2 doesnt really have much advantage over a stock turbo in the 15-18 psi range. I myself was leaning towards a stage 2 and emailed Bryan. I told him that Id like to make 320-340 whp...He told me I could certainly get there with stage2, but id be running 23-24 psi to do it. Theres quite few of us fully bolted running 16-18 psi stock turbo making 300 whp..and thats prabaly where your gonna be at with the stage2..maybe 5-10 more whp..but thats it..to make "more" power youll need to push that stage2 beyond the psi range you want, BUT it should run alittle cooler than the stocker, and not smoke on you, and honestly thats prabaly the main reason why you should buy it, Certainly not to make MORE power but not go over 18 psi..just not gonna happen.

True........and with my protune I still hold 16-17 psi to around 6300 or so..but ALOT of people do not hold boost very good the with stock wga, and I can totaly see where coldrice is coming from.

exactly, it's basically throwing $1200 at something that's built a bit better than the stock k04. this coupled with you not wanting to run the turbo over 16psi and not to redline... it seems like a total waste of time and money to me. i would've just bought a bunch of stock k04's - you could probably buy at least 6 used k04's for $1200.


jasper, are there any tuning solutions for your ecu?

well the EU ECU seems to work a bit different from the USDM ECU from the tuner that i talked to putting 300HP whit a stock turbo wouldent be a problem he has tuned around 20 Mazda 3 MPS.

he said runing 1.3bar boost wouldent be a problem but iam going to see what the car makes on the Dyno and than ill see what i want. cant say for sure now what the car would do.

iam not looking to make a tikking timebomb i want steady HP and no top HP and that is what the stage2 can do for me. just wait and see

@Ms3speed:

ill will be posting a complete Manual on how to install and what parts you would need and tools and stuff. cause you do need some new hoses to connect everthing up and you would need to move the stock boost solenoid but just wait for me to get it done and it will be just like putting a IKEA thing togheter

[zx2man]

Yes you can make 300 whp on stock turbo...I just said that in my previous post. But you not gonna make much more power with the stage2 bnr below 20 psi!!!!.

Look I made 291 whp on a mustang dyno @ 17 psi. Since then I installed a DNP turbo mani,fmic and turboxs catback.

The car felt more responsive and pulled harder once I put the turbo mani on!..butt dyno felt nice....combine that with the fmic which makes my car run alittle cooler and my boost is now 19 instead of 17..I bet when my car gets retuned @surgeline I think ill be around 315-320 whp on that same dyno, and prabaly 330-340 whp on a dynojet. Thats pretty much it for me,fully bolted-stock turbo-properly tuned.

@ the same psi I seriously doubt your gonna make more power with the bnr stage 2....like I isaid before..its a better built turbo, but is that worth 1200 bucks? I dont know..for peace of mind..maybe for some people.....each thier own..and I can REPESCT that. But not for power purposes...not untill you push that stage2 past 20 psi will you see alittle more power. Look forward to your dyno..and also what kind of dyno-...I will do the same in the next few weeks

[Jasper_3MPS]

its a dynostar google for more information

from what i have heard of dutch chiptuner he said that hitting 350Hp should be possible whit the setup that i have so iam going at his words. and than again we will see

i think ill be happy when my car doenst smoke any more and the smoke plumes stop comeing from my exhaust

i don't think it's any more complicated than replacing the stock turbo.

[cld12pk2go]

I tend to think it is more of a problem of flow limitations on the stock turbo (compressor running up against the choke line) instead of a mechanical limitation of the stock WGA.

One question though, are the people with this issue running an upgraded exhaust manifold? If not their pre-turbine pressure would likely be a good big higher than mine resulting in more pressure against the WGA for a similar massflow making them less capable of holding higher boost pressure.

I can get ~18PSI at redline and more earlier, but this is pretty much all the stock turbo has to offer above 5000 RPMs (WGDC at 100%):



I can easily run more boost below that by just targeting higher loads, and I am currently doing that. Moving closer to 22 PSI than to 21 PSI that was my target on that run.

[xcoldricex]

look at your log - you're maxing out your wastegate and you can't hold 19psi to redline. exactly like i said. if you want to hold 19psi+ to redline, you need to upgrade your wga. the stock turbo can do it if you upgrade your wastegate...

that's why i keep encouraging jasper to run the upgraded wastegate, he's going to have the exact same problem as you on his expensive new turbo that's supposed to give him gains.

One question though, are the people with this issue running an upgraded exhaust manifold?

no, most people are using stock manifolds i believe... but i can get 22 psi all throughout the powerband.

[cld12pk2go]

Do you have logs of people holding more than 19PSI on the stock turbo with the upgraded WGA? Do they actually make more power?

I am already spinning the stock turbo well off the right side of the compressor map.

Spinning the compressor at a higher RPM might yield higher pressure (PSI) but it is unlikely to be the result of more mass flow, it will be probably be due to higher discharge temp (not good).

i know having a upgrade wastegate actuator would give more room to tune the crap out of it but thats not what iam looking for. this stage2 also has a bigger compressor house so whit the same boost you get more flow. but than again we will see.

and the wright up is just for people who think that it is a complex job and than again you do need some other parts so also handy if you dont need to look up all those parts

[xcoldricex]

considering you're basically maxing your wastegate starting at about 5k, you have 1.5k of consistent boost you're missing. yes, you make more power.

someone did dynos, i don't remember who. but there was no gain in power going from 20 to 22psi up top. going from 18 to 20, yes. search for it.

since you're running meth, i feel like you have a bit more power to squeeze out of the stock turbo...

jasper, well you'll see. i doubt you'll net much more power not turning up your boost and just relying on the compressor housing. i've already told you on numerous occassions so, you'll just have to see for yourself.

[cld12pk2go]

No luck finding the dynos you speak of after 20min of searching...

[xcoldricex]

yeah me neither. it was someone doing multiple pulls and decided to go up to 22 to compare to 20.

[Lex]

Talk to Fobio - he was able to hold more boost up top.

[xcoldricex]

yeah, he is running an upgraded wga too...
