Mazdaspeed 3 - Clocking the BNR S4 Turbo & JBR Under Route Piping Kit Install

In this video we clock the BNR S4 v2 turbo and install JBR's under route piping kit. This provides a shorter airflow path and reduces the amount of heat soak into the intercooler piping that would normally be positioned on top of the engine and behind the radiator. Enjoy the video!

Wrap the ex-manifold. It will spare you from a lot of heat in the cabin as well as all those plastic wraps of the engine harness, sensors, all kinds of hoses and so on. I have a catted downpipe and stock ex-mani (so all the heat shields in place except the turbo heat shields) and I couldn't believe hot much of a difference it made to wrap the DP. Once I moved to a catted TP I wrapped that as well. As a bonus I've got a bit of sound deadening as well.

[@WannabeTuners]

Yea header wrap should take care of the heat. This tubular manifold radiates a tonne of heat into the engine bay, especially mid summer. I imagine that a catted setup would be even hotter.

[@NewOrleansSpeed]

Yesss i was waiting for someone to make a video on these products! Thank you!

Thanks dude!

[@robwag2656]

Crazy to say I had low oil psi after driving full temp on engine for a while it scared me new built engine, well I found a crack in my resivor tank replaced it and oil pressure is perfect now! Only thing I can think about is it was running a bit hotter and the oil cooler is cooled my coolent caused oil temps to go up thinning the oil. I run rotella t6 always

[@gabrielromero756]

By any chance do u know the part number for the relocate wastegate actuator?

[@CorruptInfinityOfficial]

Wrap those headers and the turbo dude, absolutely more than helpful, people on the speed forums will likely attest to this as well and I know ur not running a stupid big turbo but the aftermarket heat shields for turbos(turbo blankets or whatever you prefer to call them) help hold that heat in the turbo which means less radiating heat to engine components, you are likely having a combination of smaller problems and not one big one for the heat soak

[@adamnyuzo2188]

I have the same full race exhaust manifold. It produces LOTS of heat, you might want to ceramic coat it AND wrap it.

[@WannabeTuners]

Yeah for sure man. It was pretty bad during the summer. Had to leave the hood open for a few minutes after engine shutdown lol

[@MikeT1551]

Hey Guys, love your videos! I've learned so much! I've been progressively modding my MS3 Gen 1 and am curious about what you're doing in the 12th minute... I have a TR8 and the under route piping kit and a BNRS4 that I have yet to install. Why do you have to re-locate the waste gate actuator? I'm assuming it's because of the way the under route kit is made? Curious if I will have to go through all of this? Any helps appreciated, thanks!

[@WannabeTuners]

The reason is that when rotating the turbo, the compressor housing is larger on that side, causing the actuator to contact it. The larger bracket provided by BNR allows the actuator to clear the compressor housing. Just give Bryan at BNR a call :)

[@MattA-fi5qe]

[@phantograms]

Awesome videos brutha! They've been very helpful and inspirational. I'm considering the JBR undermount intercooler piping and wondering if yours is running good so far without any issues? Thanks in advance! Looking forward to your next vid.

[@WannabeTuners]

Awesome man, glad to hear. The JBR under route piping has been very good. It has a lot of adjustability to ensure things don't rub. I had some issues with contact at the passenger side driveshaft and subframe, but since zipties come in handy and with all the adjustability, that wasn't a problem for very long. Just keep an eye on rub points and adjust as needed :)

[@JackBurton871]

Wastegate arm should have a little bit of pre-load. At least enough that you have to pull the arm a tiny but to get it on the flapper. This keeps the wastegate seated so you are not leaking air that could help with spool. I know you are creeping and this won't help that any but in the summer time you are just wasting air that could be spooling that turbo as the wg is letting air bypass before it has done its job with a loose flapper. The only way you are going to get rid of creep at this point is with an external wg and either dump of recirc it. Keep up the good content.

[@WannabeTuners]

Yeah man I learned that the hard way when my flapper would rattle. After a few preload adjustments it's nice and tight now :) If I ever build the block I may go with a BNR S5 which has the ewg on the turbine housing

[@JackBurton871]

@@WannabeTuners s5 is pretty sexy. I am going built now and looking at PTE 5862 but for stock ease s5 looks really good. My goal is 550 whp should not bee too hard with 5862. CS new turbo and mani are very tempting as well.....if they ever release them.

[@WannabeTuners]

@@JackBurton871 Oh yeah tonnes of ways to go. I figure S5 because then I could retain my EM and DP, and I can't see myself wanting more than an S5 could deliver lol

That is alot of work you guys. Really nice build , but I'm still skeptical about that driveahaft getting hit by that piping. So I might just go with top piping. Even though , Big respect to you guys Awesome build.

[@WannabeTuners]

It takes a little bit of adjusting with the clamps and pipes. But tbh there is a lot of adjustability so its really nothing to worry about :)

[@blazonemore2]

i run under routed with no issues. jbr kit works good. my hot and cold pipes are 1 piece aluminum custom hot and cold pipes

[@Mazdaspeedgarage]

How is to performance on the Corksport Intake manifold

[@WannabeTuners]

Absolutely amazing! The stock intake manifold seems to choke the engine out below 3500 rpm

[@keithiscupcakefury]

When u clocked the turbo did you have to seal those bolts?

[@WannabeTuners]

They did already have some sealant on them, so we just put them back in without any noticeable issues, however it can't hurt to add some thread sealant on them just to be 100% sure that there won't be any minor boost leaks ;)

[@seanknutson2799]

I have a 2ed gen how do know how much to clock the turbo

[@WannabeTuners]

Basically u want to start by clocking it 180 degrees pointing down. Then once it's installed in the car, u can make final adjustments in relation to the under route piping, and then tighten the compressor housing fully down evenly. It takes quite a bit of patience to ensure everything is done properly and to your liking :)

[@JackBurton871]

Do you guys know what size the bolts are on the housing? A friend of mine lost a bolt and was looking for sizing, BNR has not replied yet and thought you might know.

[@WannabeTuners]

Unfortunately we don't know. Maybe try taking one to home depot to find a match?

[@JackBurton871]

@@WannabeTuners He just got the info m8 1.25 10 or 15mm, thanks though

[@bananahammock789]

Time to upgrade to an AP V3! Gotta keep an eye on more than one thing. But these S4s and the creep is bad. Going EWG on my setup to get rid of it. It's so bad, even with my actuator maxed out. Also, I recommend using a short 14mm socket with a swivel extension for the downpipe. You'll be able to get all of the nuts from up top without having to go under the car. Takes me less than 10 minutes to remove my ATP catless downpipe. PS: Never shave again. Please.

[@blazonemore2]

i will never iwg again. next setup will be EWG. iwg caused me and my tuner a lot of wasted time.

[@WannabeTuners]

FYI boost creep happens when the IWG cannot bypass enough exhaust gasses to limit the speed of the turbine wheel. Increasing the preload on the wastegate actuator will in fact help the turbo spool up if it was previously opening at too low of a boost pressure, but having the actuator set with too much preload may limit it's travel making the turbo creep even worse in the mid to high rpm range :)

[@mjl6425]

So using those tools you could take the turbo off the car without going underneath?

[@bananahammock789]

@@mjl6425 No, the downpipe. Not the turbo.

[@gimmethecarkeys]

@@WannabeTuners as long as it works thats whats important. I have seen 1 other jbr underroute kit. Personally I only use his crash bar. Not a fan of the all silicone couplers. I understand the benefit it offers. But if a kit is built right it should fit right. My htp fmic kit fits way different than yours. I have clearance everywhere and it looks cleaner.

[@WannabeTuners]

@@gimmethecarkeys Awesome man! Definitely something to consider for those interested in going this route. My only concern is if there is as much adjustability with the HTP kit with different sized compressor housings and turbos. I know the JBR kit can be manipulated quite a bit with all the couplers and what not :)

[@angelofdarkness8012]

I ran into an issue when clocking the BNR S4. I have a coolant line smashed up against the turbo outlet. Did you guys experience that? I can send a picture if you have a place for me to send it.

[@WannabeTuners]

Yep we had the same issue. It prevented the turbo from being clocked further to the back, so all we did what get it as close as we could without putting too much pressure against the coolant hose, or the nipple on the metal pipe that the coolant hose attaches to. Then we made adjustments to the under route piping and tightened everything down. It's inconvenient that that coolant hose is in the way, but it still works :)

[@alexalvarado2972]

[@WannabeTuners]

@@davidmedina4173 The JBR under route piping can be manipulated quite a bit, so I don't see it being an issue. I would ask around on the forums to be sure. The only potential issue might be that coolant return hose being a bit tight around the 3071's comp housing, but maybe there is a way to route it differently. We show the return hose near the end of the video :)

[@o.rgarage9660]

Idk if you guys will see this but if you do, I have a question, I’d you have stock ko4 do you need to clock it for the piping?

[@WannabeTuners]

Yes if you plan on running under route piping, the compressor housing on the stock turbo will need to be clocked. It may be difficult though because the hoses going to the turbo and the boost control solenoid may need to be relocated.

@@WannabeTuners UGH it’s so hard to have a clean engine bay😭 also where did you get that air duck thingy idk what it’s called but where the hood latch goes? And do you know if there’s one in carbon? I’ve been looking for something like that for my gen 1

[@kwbalance108]

Why does the BGM sound like it's from P rince of Persia lol

[@blazonemore2]

You need a lot of preload pressure on that waste gate.!

[@WannabeTuners]

This BNR S4 wastegate is rated to 18 psi and my car creeps up to about 23 psi with this high flowing setup at 0% wgdc in cold weather. I think u are talking about the S3 actuator right?

[@blazonemore2]

@@WannabeTuners Yes the actuator arm. needs to have a bunch of preload holding the gate closed. you did a good job fitting /bending the arm to go on smoothly. but you did not show adjusting the prelaod it needs to hold it closed under boost. that will cause slow spool and boost creep issues. the actuator needs a bunch of prelaod to get all the boost you want. it is a lot easier to set it now before you have it all back together. i had this issue on my car under route set up with a gtx turbo. had to go back and add more prelaod 3 times to get it right.

[@blazonemore2]

with too little of preload my wastegate would start to open at 8psi and would spool slow. i could also barely get over 22psi. after adding a bunch of prelaod may car spools fast and i hit 30psi easy.

[@WannabeTuners]

@@blazonemore2 I hear ya man. The wg actuator that comes with the S4 is pretty stiff and doesn't have any issues with spool. This turbo suffers from boost creep, mainly in cooler weather, but it's nothing tuning can't solve ;) When fitting the wg actuator rod to the arm, I found it's a good idea to adjust the rod length slightly shorter than it needs to be, so that it applies slight pressure on the wg flap in the closed position to prevent it from rattling at idle. In the video you can see that the rod is pretty loose sliding onto the arm, which caused the wg flap to rattle at idle. I had to remove the actuator several times to get the rod length just right so that it would apply slight pressure to the wg flap in the closed position :)

[@blazonemore2]

@@WannabeTuners slight pressure will work. but if you really crank it down so its maxed out. you will wake up you spool and boost by a lot. and your boost creep will pretty much go away. just my opinion tho. i did what my tuner nishan told me to do and now may car runs a lot better. 22 psi vs 30 psi. light pressure vs max. turbo spools at 20psi at 3k now. before it hit 20psi at 5500rpm.
