daaaaaamn son

[@WannabeTuners]

yeeaahh buddy!

[@NewDemons666]

Ughhhh I can't wait! Finally came back to watch this video again after a while. My SP63 stage 1 long block should be done soon and I have almost all of my bolt ons! 😊

[@WannabeTuners]

Beauty! It's gonna be blast

[@knappe3223]

Im doing the same install right now, with a few different mods, thanks for the video, im going to be posting mine too so I can compare builds.

[@WannabeTuners]

Awesome man! This turbo rocks.

[@corderomccargo4500]

Was going to stop watching when you just jumped to taking out the turbo. Love your sense of humor. #subscribed

[@WannabeTuners]

sasuke uchiha haha thanks buddy. We're kind of weird😊

[@corderomccargo4500]

Wannabe Tuners it's awesome. Me and my buddy are the same. Buying a ms3 next month. Any advice?

[@WannabeTuners]

sasuke uchiha Awesome! It really depends. Is the car stock? I would say read as much as you can on the mazdaspeed forums and always run the highest octane from reputable gas stations. Also don't floor it below 3000 rpm's. And if you tune it, make sure to upgrade the high pressure fuel pump internals.

[@corderomccargo4500]

Wannabe Tuners it is stock. Not even a intake. So I'll be starting from scratch. It'll be a daily driver so 320WTQ is good for me. Nothing too crazy.

[@WannabeTuners]

Nice, I'd recommend upgrading HPFP internals first, then get an Accessport. If you want to save money, have a HP goal and buy the right parts the first time. I'm on my third intake, and my upgraded TMIC is getting replaced with a FMIC. There are so many things that I bought and ended up getting rid of. I could have saved thousands!

[@grysx4160]

I've got a gen won and I have FBO and had a BNR S4 but just bought a GTX3076 and custom made a dump pipe with a 38mm purge valve. I run 91oct on the street, I have a tune with E30, and a tune with full e85 and meth for the track. You can up the boost on the S4 of you want to I was running 28 PSI on mine. Loved the video man!

[@WannabeTuners]

Oh man that's awesome! Are you using meth injection for aux fueling? Thanks for watching, we appreciate it!

[@grysx4160]

Wannabe Tuners ya it's on a valve so I won't feed 24/7 when I'm wot lol.

[@BruteCo]

Man you guys make it looks so easy, I’m stuck removing my exhaust manifold the bolt by the alternator is giving me trouble, and one of the manifold to turbo bolts fricken rounded so I just don’t know what to do anymore gotta love Mazdas

[@WannabeTuners]

Oh man, might have to hammer on a smaller socket to take that nut off. The alternator shield might not need to be taken out. From what I remember, the oil feed line is actually bolted to the exhaust manifold underneath it making it hard to take out.

[@Reconbeatz509]

I took out all of my heat shielding. Kept getting in the way

[@johnkearns2265]

I'm debating on this turbo upgrade or corksports cst4. Love the vids you guys are hilarious, but I cant wait to see your newly built engine after blowing this one because I recently did the same and upgraded to overspeed motorsports stage 0 longblock... much needed buy lol

[@WannabeTuners]

Good stuff man! Both the BNR S4 and CST4 are good choices

[@solomonhauraki2600]

I did the same thing for the oilfeed line too😂

[@AJPanda24]

Great vid. Loving the white too. Keep it up. I just subscribed. Looking to see more vids.

[@WannabeTuners]

Thanks man! We will:)

[@raychu7472]

keep up the good work! 👍

[@ledoubleagent96]

Did you guys directly swap the coolant feed line over from the ko4 or did you use the one that came with the bnr? i bought a second hand bnr s4 and i don’t think i got the coolant feed line with it but i’ll have to check.

[@WannabeTuners]

If I recall correctly the BNR S4 came with a coolant line. I think calling BNR might be a good idea to be 100% sure

[@solomonhauraki2600]

To change my manifold i just bent the heat shield and took the bracket off then bent it back to put the heatshield back on😂😂

[@WannabeTuners]

That's one way to do it haha

[@joshmac7245]

lol i think i was driving that silver/blue-ish caravan at the end there

[@WannabeTuners]

Josh Mac Oh no way, you recognize the plate?

[@joshmac7245]

yea it looks right and the color and where we were makes sense but that van died a few months back now. also ive seen you MS3 before but couldnt figure out where until i saw that part...keep up the good work guys

[@krimnoodle]

Im installing a bnr stage 1 and i was wonder what I torque the 9 studs on the turbo to?

[@WannabeTuners]

Unfortunately I don't know what the torque specs are off the top of my head, but I'm sure that info could be found online. I've always just tightened them by feel in an even tightening sequence.

[@mjl6425]

With this turbo do you always have to get the revs up and then punch it? Or can you punch it when you hit 3000 RPM?

[@WannabeTuners]

It doesn't spool until about 35k rpm. Anything past that and your laughing. Flooring it at 3k rpm isn't going to impress very much :) By shifting the power curve to the right, it's much safer for the stock rods. As always a good tune is very important.

[@mjl6425]

Yeah definitely looks like a lot of fun anticipating the sudden rush of power, that’s what I love about turbo cars. But what about once the car is rolling and I need to make an instant pass? I can’t be waiting for it to spool up while I pass the Prius driver.

[@WannabeTuners]

@@mjl6425LOL u just downshift ! It's not a complete dog at 3k rpm. The Bnr s4 is pretty darn responsive for the amount of power it can deliver. I think it delivers power in a smoother fashion than the k04

[@mjl6425]

That’s the answer I was looking for lol! What about normal drivability under 3500 rpm? Like stop and go traffic, does it feel bogged down at all since the power band is higher?

[@mjl6425]

Of course that’s what I had in mind lol. Does it come with everything you need like the Corksport turbo kit?

[@tylerallen4469]

So CS now makes a 3.5 bar map sensor that is a direct plug and play. I bout that one and didnt realize I wouldn't need the bitwise harness... so now I have an extra one I guess. I kinda like that it is a direct replacement tho ya know.

[@WannabeTuners]

That's really good to know man thanks! :D

[@corporalmcna5ty734]

Can a turbo and intercooler fit into a 2010 2.5l NON TURBO car?

[@WannabeTuners]

Sure can, however I think it involves a lot of custom work, as turbocharging the NA version isn't very common

[@mjl6425]

I’m torn between the Cobb boost controller and Grimmspeed. How are you liking yours? Would you say one is better than the other?

[@WannabeTuners]

Nope they are both great!

[@mjl6425]

Thanks I think I’m gonna go with the Cobb because I like how it mounts in the stock location.

[@WannabeTuners]

@@mjl6425 Awesome man, yeah can't go wrong with the Cobb 3 port boost control solenoid. I've had zero issues with it!

[@LikquidDutch]

I have a s3 and I'm feeling like I want a s4 but don't know if I wanna go through all that again I know the s4 flows 5lbs more than the s3

[@WannabeTuners]

That would depend on your final goal. From what I've read the S3 spools faster then the S4 and has been taken up to 400 whp on an Ms3, maxing out the stock fuel system:)

[@fsflip3111]

how long did it take to complete? 15+/- hrs?

[@WannabeTuners]

If it's your first time doing it, definitely give yourself a whole weekend. It took us probably about 12-15 hours :)

[@seanknutson2799]

Did you need the wire harness for the map or will it work with the stcok one ?

[@WannabeTuners]

We went with the Bitwise map sensor harness for the Bosch 3 bar map sensor. Your tuner will also need to update the tune :)

[@Specer_G]

About to my own first turbo install on my speed. Is it necessary to disconnect the DP to CB? Or just DP to turbo housing? Thanks!

[@WannabeTuners]

Spencer GALE Taking the downpipe out would give you more room. Our downpipe had the flex portion on it which gave us more room. I'm not sure how much room you'd have without a flexible portion. You could try it and worse case take it out completely.

[@JohnLumapaskeith]

Ey you guys are from Mississauga? :D

[@965Ferrari]

Do the exhaust manifold bolts need to be bolted on to a certain torque spec?

[@WannabeTuners]

Every bolt on every car has a recommended torque spec that u could probably find online, but if u tighten the manifold down evenly, from inside to outside, u won't have any issues. You know the saying...go by feel ;)

[@965Ferrari]

@@WannabeTuners Dude i can't even get the damn bolts loose lol I dowsed them in PB blaster but the bitch ain't cooperating

[@AtticAZ]

Get Damond Motorsports mounts. You won't regret it.

[@WannabeTuners]

I've heard great things about those but have already installed the JBR trilogy. The NVH was higher at first, but over time the vibes got more tame. The mounts just needed to work themselves in, and now it's great.

[@Thunderstorm9667]

Installed all 3 Damond mounts and it feels insane, like a track car haha

[@geoff0707]

Hey bro so just bought a speed 3. I wanna get a bigger turbo. My car already has full bolt ons. I'm concerned about the fuel. I can't find bigger injectors for this car. How much whp will the fuel max out at with just a hpfp? Is a hpfp all I need? My goal is 400 to 450whp

[@WannabeTuners]

From what I've read, the stock fuel system with upgraded hpfp internals on the Mazdaspeed 3's will max out around 370-380 whp. An ethanol mix may be required at this power level to keep knock under control and it also eats up fueling headroom, so going with a low ethanol mix is what most guys do. Unfortunately there are no upgraded injectors for our platform. The only way to get more fuel is with an AUX fuel setup. Either meth injection, port injection, or 5th/6th port injection.

[@williamgilman7427]

get a 3.5" intake

[@darkphantom881]

Hey I have the same car as you and I have the bnrs4 as well i was wondering is it possible that I can turn the bnrs4 from internal to external wastegate at all ?

[@WannabeTuners]

You sure can! You would just need to run an exhaust manifold that can incorporate an EWG

[@WannabeTuners]

You would also need to weld the IWG flap closed, or run Cobb's IWG bracket

[@darkphantom881]

@@WannabeTuners thanks i have the cobb iwg bracket

[@seb42]

At 18:45, why do you say OCC not worth it?

[@WannabeTuners]

Lack of knowledge at the time, but I still had my EGR connected, so the valves were still getting dirty. OCC's are a must on these cars! The amount of oil that goes into the intake manifold without one is insane. I'm not sure if an OCC completely eliminates dirty valves but it definitely helps, based on all the oil that drains out of it:)

[@seb42]

Ah that makes sense. So optimally you'd want an OCC as well as a EGR block off plate

[@MRDRWIGGLE]

How did you move the coolant hose for the intake?

[@WannabeTuners]

The coolant hose needed to be extended with a heater hose extension

[@fsflip3111]

how long did it take to get the turbo put in?

[@WannabeTuners]

The job by it self would probably run a full day. Depends on experience, we found our selves scratching our heads here and there which wasted a bit of time. Maybe ~10 hours more or less if I had to guess (took us alot longer because we filmed and hadn't done it before), but we ran into stuck bolts and little annoyances

[@fsflip3111]

thanks for reply.. keep the vids coming

[@fsflip3111]

so overall comparason between s4 vs k04 with e85?? is it worth the hassel?

[@WannabeTuners]

Absolutely! It's safer for your rods because it can't generate excessive boost at low rpm's, and it pulls like a monster above 4000 rpm. It also sound splendid! Obviously the tune is most important. The stock fuel system should be able to take the car up to around 370 - 380 whp on an e85 mix, without the BNR S4 even breaking a sweat. This turbo has been taken up to about 450 whp with auxiliary fueling such as meth injection. We're still running a base map until we can get the Guardian Angel up and running.

[@fsflip3111]

man, i was looking into either e85 or meth just on the stock k04.. but i could just do pump 93 and go bnrs4 its sounds like that is the better option.. .. was the meth kit hard to install /maintain?

[@nickpasowicz5203]

i thought the v2 was a ball bearing turbo?

[@WannabeTuners]

From what I am aware of, the only difference between the V1 and V2 is the compressor housing. Either way, this things rocks so far! And the price is right also:)

[@Ericnegroo]

Is there a break In period on a new bnr s4?

[@WannabeTuners]

eric negron I called Bryan at BNR and asked the same question and he told me "No sir, just drive it like you stole it" lol. One thing I do recommend is to make sure your crankcase pressures are vented properly as it is a journal bearing and if oil cannot drain back efficiently is can seep past the rings/seals and get into the exhaust causing smoking and oil consumption☺

[@Ericnegroo]

Wannabe Tuners okay got it ! What’s recommended a vented or sealed occ?

[@WannabeTuners]

eric negron From what I've read a vented oil catch can should work great. I personally have a jbr sealed OCC with check valve (to prevent pressurizing the can with boost) and I'm going to install a Gen 2 valve cover paired with an sp63 oil breather cap to vent the pressure. I tried teeing off a second check valve with debris filter along the hose from the intake manifold to the can, but I don't think it was enough as I still get smoke at WOT and oil consumption. I'm hoping the Gen 2 VC and breather cap along with the jbr oil restrictor bolt will solve the issue.

[@Ericnegroo]

Wannabe Tuners thanks for the info ! I’ll be doing a similar set up. How’s the bnr running ?

[@WannabeTuners]

eric negron Aside from the smoking at WOT it's running great. I'll be taking it easy on the car until we install a whole bunch of performance parts and dial in a nice solid tune.

[@visionarydreamz8957]

My jbr Intake won’t let me put my oem battery tray and the intake won’t fit properly for the bnr s4 any tips?

[@WannabeTuners]

What size intake is it? U will most likely need to relocate the ECU, usually onto the fuse box

[@visionarydreamz8957]

3.5 jbr intake

[@WannabeTuners]

@@visionarydreamz8957 Yeah u can always run a T51R battery box, but cutting / modifying the stock battery box and relocating the ECU onto the fuse box will work

[@visionarydreamz8957]

My car won’t turn over, after bnr s4, FMIC, jbr 3.5” intake, egr delete, 3”map sensor. It’s at my tuner and they told me it won’t turn over

[@WannabeTuners]

@@visionarydreamz8957 Has the tune been updated to accommodate the larger intake and 3 bar map sensor?

[@vickarious808]

Girls: boys only want one thing and its disgusting Boys: BNR S4 Turbo

[@trattgarage7973]

Get off that base tune asap bro. Protune will wake the car up are run much safer. I have a video from getting my PDtune and logs.

[@trattgarage7973]

You also gota delete that VTCS and EGR!! More power bros!!

[@WannabeTuners]

I've heard great things about PD Tuning, I may end up going with an E-tune at some point, but self tuning is a good learning experience! EGR was unplugged recently, and Idk about deleting the VTCS because of emission laws. I am already able to flow more air than the stock injectors can handle on completely stock manifolds, but I know what you mean man!

[@WannabeTuners]

Thanks I've heard good things about him also:)
