The OEM bolts are T30, and that obstructed bolt can be removed with a long shank T27. After assembling the new GFB+unit, hold it in place with some painters tape over the top to the turbo flange. Slide the solenoid with new spring and piston in from below, then tilting it forward to GFB. Once the solenoid ears get past the block, place a new bolt thru the solenoid ear on the top right. I held the solenoid with my left hand while using a pickup magnet to hold the bolt while I slid it thru that ear. You have to do that before moving the solenoid up and onto the GFB+. It's the only way to get that back bolt into place. If i did this job again, once the valve was removed, I'd Dremel the block flange that obscures that back bolt to open a channel for the long shank bits
Beware this is not as straight forward as you might think. Make sure you have the ball end bits and basically everything in the tools you might need in the link he attached. Get ready for your patience to be tested but take an hour, grab a beer, and then get back to it. Have fun!!! Also be care with the intake inlet, the plastic is fragile especially the bolt hole that connects the inlet to the turbo.
Brian you need to open up a shop here in San Diego California!!! Your so awesome sharing your automotive knowledge on bmw’s . Thanks again for another wonderful and awesome video 👍👍👍
Never has one little bolt befuddled me like this one did. 😂 Night time came and I shut everything down. Next day at work in the OR I came up with the bright idea to use a locking hemostat to grip the bolt and slide it into position. Also used a 25mm bolt instead of 30mm for the top right bolt. I’d rather get nagged by my wife than do that again. Good video. Gave me a good idea of the installation and what I was up against. My N26 block has some sort of flange on the block. Next time I’ll Dremel that piece enough to make room. Thanks
@@KiesMotorsports When you do that video, please do some before and afters of the throttle response. I'm FBO right now and the DV and Stage 2 LPFP are my next two mods! Keep rocking!
U talking bout that top right one right I couldn't get it at all left mine with only 2 bolts seemed tight enough but bothers me every time I think about it... We're u able to get it?
Ended up just wiggling and shoving mine in. Used a flat head to screw it all the way in. Will be getting a ball end hex and grinding it down even thinner to get it tight
RIP. I install the Intake. I have to uninstall to install the inlet. I install the inlet, I now have to uninstall to install the diverter. What a mess lol. I love these videos they are like gold but but I wish I knew which order to assemble!
@@TfromDaygo it ain’t. I already spent 2 days installing it. The t30 bolt on the top right (closest to the motor) is hard. The long ball just won’t grip on to take it off.

Those long hex ball 4mm tool stripped my torx bolts.. its a hit or miss. Its best to find one thats of good quality and is sharp on the edges in order to actually bite the bolt as you turn it. It doesnt matter if you strip the original bolts because the GFB kit comes with new Allan bolts. But still its something to consider when trying to remove these
I have a 2014 320i and I'm really thinking about getting BM3 stage 1. My car is a manual 6 speed and haven't seen any vids or reviews on a six speed. Just a bit skeptical but I'm wondering if it will perform like a 328i. Lmk if you think it will be safe on a six speed. Thanks bro!!
Just installed on a F20 N20 125i with an MST intake, charge pipes, vrsf stepped intercooler, custom 3" turbo back exhaust and bm3 stage 2. It definitely flutters, but not as much as the owner of this car shows on his channel and it also seems 'delayed'. Will be doing the MST inlet elbow as well but I doubt it would help with flutter. Tried loading it when stationary, high boost low rpm, etc. Nothing seems to work.
Dont know if youve jnstalled it yet but to answer your question it is good for holding boost better and it is way quieter than stock in most driving and since you have a stock intake it might be completely silent at times which can vary your opinion on it greatly.
This is totally not that simple on the F36 Grand Coupe as there is basically a wall stopping you from tightening that back screw it was a nightmare lol. nonetheless the tools you put on amazon was awesome andthe video helped a bit.
I have the same vehicle. Can't get the top right screw out on the diverter valve. Even with the long ball joint bits. It just spins inside and won't grab. Had to put it all back together. Thinking of calling a mobile mechanic to see if he could get it out fot me and install the valve.
Thanks for sharing. I bought and installed this go fast bits diverter on my 328i n20. Unfortunately I do not hear the turbo fluttering as expected. Only a higher pitched spool. Any idea the reason? I have stage1 and big sport intake besides. Thanks.
I installed this with the ball joint alen key and the alen key got stuck between the OEM diverter valve and the block, tried to pry it out ended up hitting one of my coolant hoses and now coolant is leaking. Don't try unless mechanical inclined
Yes! Here is the link to the Go Fast Bits DV for the N55! We're working on making a dedicated tutorial for it soon but you can check out our Pure turbo upgrade video where we explain how to do it on the N55! www.kiesmotorsports.com/products/go-fast-bits-dv-diverter-valve-t9356-f30-335i-f20-f21-m235i?variant=16919315513459?aff=14
Anyone else have the issue where their go fast bits dv didn’t sit flush into the bmw diverter housing. Mine wouldn’t sit flush at all i gotta repull it off and then dremel out some space for the spacer to sit in better
Yes, it is possible but we found this way works best and saves the most time, especially because you still have to take the waste gate off to reach the diverter valve!
Hello, could you help please, we installed DV+ on n20 with spring, we don’t hear any noise like whooosh, is it normal? or we did something wrong? Thanks in advance for answer
I have the same issue, installed dv+ with their spring and injen intake and no sound, although im unsure if the reason i cant hear it is because of how loud my exhaust is
Didn't either, instructions also didn't say that. He also made the installation harder for himself by taking it apart again and installing it with the entire thing loose, i installed it in 5 mins lol.
Hey man, I bought those smoked led sidemarkers from yall through Justins link and my left side keeps falling out. The right one is fine. Any chance yall can replace the left side marker?
@@KiesMotorsports hey thanx Brian. I just sent you guys an email with a foward from where i purchased them explaining whats going on. Thanks for the response!
How in the heck do you get the screws out? I bought the ball joint Neiko hex sockets that you recommended, but the 4mm just doesn’t grip well enough. I’m afraid to strip them. Did the hidden one first with a ratchet extension like you suggested... at least I thought I loosened it up. Moved on to the two top bolts before finishing that one, only to find that the ball joint hex doesn’t really grip well and actually spins in the head of the screw. Now I’m worried that the bottom screw was just spinning in the head since we obviously can’t see it. Used the recommended tools. What gives? Any suggestions?
Not sure if you ever figured it out. I just did mine and the screws ended up being T30, not the 4mm. My big problem is getting the top right screw back in. There isn’t enough room to get it in the hole.
Will I throw any codes installing this on my 15 320Xi N20? Dinan Stage 1, K&N filter and AWE exhaust (midpipe and catback). With the extra boost from the Stage 1 tune I just want to do some preventative maintenance on the DV so it doesn't lose pressure over time.
If you install it without the large spring you're good. If you do install the large spring for the "sport" feel it will send a drivetrain code and derate the engine. If you keep your rpms high, this can be avoided. Something to do with back pressure on the turbo.
Hey Brian, I have a question for you. I just recently as of today installed a GFB diverter valve on to my 535i n55 and I'm getting fluttering sounds as if there's turbo surge going on. I also have a code "122108 BOV seized closed". I was reading on the internet somewhere that the code "122108 BOV seized closed" -- ignore, tuner code due to the piston of the GFB DV snapping shut really quickly " progressively closing" that's producing the fluttering. I need alittle help with this, wasnt sure if you have heard anything like this or about this issue?
Hi. I think I'm getting the same thing. Are you gettingy it during wot or once releasing throttle? I'm getting it during on low rpm, which is worrying me.
Any benefit in upgrading this, also a 2012 528i upgrading the charge pipe and intercooler and installing a BOV and getting performance coils has anyone done this.
Idk if you found your answer elsewhere....but the factory one if I recall is plastic and prone to cracking over time. The gfb DV+ also has a better spring, as said in the vid, to help maintain better boost. Your doin it right so far for sure upgrading those parts. I would say the best “performance” mods are the turbo inlet, both sides charge pipes, diverter valve, and oil filter housing cap. Each has their own “failure” over time whether it’s cracking because it’s plastic or like the turbo inlet; prone to collapsing because it’s cheap rubber. Hope this helps😊
@@joshbeveridge9153 I actually don't know if you know this but I have one of these on my current n55 535i xDrive and it's producing a fluttering sound.. also known as turbo flutter or turbo surge.. you might as well throw a fistful of sand in your intake pipe as the car is revving up to 7000 RPM. I'm hopefully going to get this issue resolved tomorrow when I pull the whole unit off again but my original diaphragm was eating to shit had 1 massive hole in it. Either way I just may end up removing the mass of spring behind the Piston because apparently the valve still works without it

Just installed a diverter valve on f32 the screws are T30 not 4am hex makes a big difference getting that top back screw out

2016 328i F30 N26 here and the bolts on the stock diverter valve are actually TORX T30 not hex bolts. The gfb provided bolts are hex 5mm FYI

What is the difference between the diverter and blow off valve?
If I install this Diverter valve will it trigger an ECU code?
The diverted valve has t30 but you can use a 4mm hex it worked for me
Thanks again Bryan!
Of course! Thanks for your support!
