Tbh I wasn’t shocked reading that title…
Same
Who wasn’t
I’m not surprised after reading that title
😮😮😮
Donut inspires me.. My parents said if i get 50K followers They'd buy me a professional camera for recording..begging u guys , literally
Begging...
This makes me feel better about all the problems I have with my cars.
Mine needs an engine swap or rebuild, transmission also needs to also be swap or rebuilt, so I got that going for me, and a few dents and a fresh paint job,
@@Rizer1231 one step at a time. My car used to be where yours is but only needs an engine now. Taught myself to do bodywork and swapped the trans with some buddies one weekend. So progress is slow, but I'm building it the way I want and taking the time to do it right so im happy with where It's come with it so far.
@Aupexx I don't have the space for mine or experience, I can do small things, but engine and transmission, I'll have to leave to the shop the I trust. But yeah, slowly and overtime.
I couldn't imagine dumping $100K into a Nissan 350Z. I feel so much better about every financial mistake I have ever made in life.
Does it really though?
zach is definetly my favorite host, with jeremiah on a close second! love all the crazy sh*t donut does. keep on killing it!
Jeremiah is in a tie for first with Zach imo then everyone else is pretty far behind
@@DeltathegoldenretrieverThose two are my favorite as well
Same!
Have y’all thought about doing a long term update on how the parts across all of the hi/lo cars are doing? I feel like that longevity of what you put on also plays a big role in the price
"This is the last thing it needs, right?" Everyone who has ever had a project car felt that.
It's almost uttered like a curse upon your vehicle. And yet, we can't all help but say it aloud.
Only to a person who is working on their FIRST project car.
You learn quickly by #2.
And by 20+ you know a car is NEVER finished.
that actually hit me right in the feels! 🤣
@@beowulfbelmont2578 It's secretly subconscious self-sabotage. We don't want to finish them. We only want to work on them and seemingly complain about how annoying it is that things aren't working/fitting right, but we love it. Every bit of it. 🤣😭
Unfortunately I've not had the opportunity to work on project a car (would be epic though).
I do understand the pain of something that should work on paper though, and all the parts work elsewhere... But then there's always that ONE dang problem that makes it drag on. :P
I know you guys have a ton of projects going on, but we definitely will be needing a new hi/low here again soon. Watched the Tacoma series at least 3 times over and NEED MORE HI/LOW!!!
Tacoma was great. Z cars was great. Subaru hi low was toilet water
@@allenmichaud1605 AGREED 💯
@@allenmichaud1605because Subaru are crap cars
If they did Hondas it would’ve been fun
Definitely need more hi/low. I'd love if they did like mini trucks or old schools.
@@allenmichaud1605 toilet water is a great way to put it!😂 still, even if their season goes awfully, we still get good entertainment and I'm always learning something (typically the intricacies of different cars)
i love that donut is honest about the condition of all their project cars and what’s wrong. i love that they never give up either good job y’all🙏🏽
I love how you went from working out of your home garage to having a legit shop and even a lift for parking struggles because you have so many projects.
Bring back Bart’s Science Garage!!! You do some, but his quirky way was great!!
I love how the cheap junkyard Ls is 100 times better than the crate motor 😂
For real
Why is that?
I guess they don’t make ‘em like they used to
@@UberLummoxgave way less issues and iirc did better speeds
How is that the motors fault?😂
I remember a while ago y'all made a video on all the issues you guys had with all the project cars, would love to see more follow up videos like this of y'all fixing them and falling in love with the cars again.
I don’t really work on cars so bleeding the brakes gave me flashbacks to my dad yelling at me and wrenches flying when I was a kid😂
😂😂😂
Love the troubleshooting. Nice job guys.
There's a chance that the water pump is over-pumping. Typically the effective range is about 5000rpm, but if you're exceeding that, the water won't have enough time to cool before re-entering the engine. You can either change the pulley size or goto an electronic waterpump.
Going electric frees up HP for the engine, too.
@@Kinannwell supposedly, I think it won't change it much because the alternator will just be put under more load and in turn that results in more load on the engine from the alternator, I think it would free up some horsepower if the water pump ran completely independent from the alternator and rest of the system on a battery. But I think going to an electric water pump makes the pumping of the water more consistent because it doesn't rely on engine rpm anymore. Anyway I could be wrong but that's my first thoughts anyway.
@@JuniorJunisonit would increase efficiency a bit. There's less energy loss from electric motors
@@JuniorJunisonwhilst you are correct in saying going from a belt driven water pump to an electric water pump will put more load on the alternator. The parasitic hp loss from increased load on the alternator is much less than from a belt driven pulley.
@@JuniorJunison There's no longer parasitic belt loss when you remove the pulley. Agree, no such thing as free energy and you can't argue with Ohm's Law.
There are 2 different reluctors for LS's crank signal. The 24x and the 58x. Make sure your sensor matches your wheel in the engine and make sure both of those match the ECU. Thanks for the content!
They also completely neglected to think about the wheel itself. Too big of a gap or a defect in the wheel = no signal.
Came here to say this, or at least something similar. Gotta make sure the reluctor is correct as well as the distance between the two.
I swapped a 4.6 from an 09 F150 into an SN95 a few years ago and had constant cam position faults. Turned out the cam reluctor on the F150 had several more “teeth”.
You're both probably right, but the custom ECU will be far more tolerant of weak sensor outputs than stock. They can be tuned to be road compliant too, even having switchable maps
@@mandrakejakemight not be the right place to ask but what makes custom ones street illegal
@@Baseball4mnstarz tailpipe emmisions when tested. If you tune for performance, you'll likely emit too much unburnt fuel. You can have 2 maps on most ECUs though.
Every so often y'all make a perfect video. This is one of those times. Primo entertainment and even a plot development pace that keeps me engaged. I love this whole series 🤘
“No lube or nothing I knew you were different” 💀
this series has been going on forever but it is Great! lets see how long it will go for
I only learned of it a couple of weeks ago and love it. Gotta love the internet. So many gems out there still to discover.
i don’t think this is considered a part of the series lol
I don't know if Adam is more comfortable on camera now or just that in love with these cars, but he was great this episode, so nice to see these things ripping, I think we all love these Zs more than we probably should
i think it’s a bit of both. adam races and most donut videos don’t involve racing
Seeing high-low Z's made my day. I haven't been this excited for a donut video in a while
Hey just wanna say whoever is doing the editing is killing it, comedic timing was great this video. Keep it up and give them a raise!
I GOT CHILLS when you guys got the shot! Man it was cool to see James and Nolan just bro it up on the sidelines and commentate!
I love you guys for not giving up on these things.. I'm just sorry that y'all don't have the greatest luck with company projects 😢
it`s not only about luck you know...
It's a skill issue 😂
@@Reno420alex true. 100k and sh*t aint sh*tting. They got insane production quality but in terms of car builds…not in the top league fosho
It creates content. That's their whole business plan. Make content. Post on social media. Get views. Sell t-shirts. Make bank. Repeat.
@user-cw2tw1um8i yeah it nakes it fun that way
Like the use of the "Perfect" sample at the end there, that was a nice touch and a sick drift.
I miss the detailed videos even if they were longer or in more parts. I felt like I really learned more.
man the editing on these videos are really taking a step up. good comedic timing, great angles and cuts. keep it up boys!
Some notes when testing wiring integrity, multimeter leads can splay the terminals in the connector and prevent good contact. You can also have bad wiring that passes a continuity check, but doesn't carry current when loaded. If you wire in a lightbulb to load test the wiring, you will be able to basically 100% confirm good wiring. It would be really cool if you guys tried using an oscilloscope to view the crank sensor pattern since this will show you the waveform that the ECU sees and you can see if you have signal, bad exciter ring, etc
Also won't show a contact that is intermittent under vibration. Can't fully take it off the list without shaking the wiring from one side to the other. And I agree a cheap handheld oscilloscope is really useful for these type of sensor debugging. Also the built-in oscilloscope in the Haltech Elite series is great for figuring out what the ECU is really seeing.
Easy tiger, I think this is way too advanced for the Donut team. This a group of guys that damage seals during installation.
@@FG-418 Ya the Link also has a built in scope and makes it nice tracking down and trigger related issues.
Possible overheating issues:
Try filling your system with glycol or straight water. Using traditional antifreeze raises the freezing temperature but lowers the boiling point of the water it's mixed with. In your climate, there's no need to worry about freezing temperatures.
You have a small grill on that car. That will restrict air flow. Since you aren't pushing wind at highway speeds, you'll have to draw in more air. Try releasing more air toward the firewall (directly ahead of the door hinges or further back on the hood toward the windshield). That and having a more aggressive fan.
James' comment about "ya know, donut" honestly made me sad. It sucks to see them have so many problems because I, and I'm sure many others, love the stuff they put out.
I mean it prolly doesn’t help them with creating content’s especially if they need to fix but tbh that’s what makes it better, we get to see them build it, talk about the issues, pretty much a. Learning process for us if we do something similar
Everyone has problems when building cars. They're not unique that way.
@UberLummox that's not what I'm saying, dude.
@@devonburkhalter9840 What are you trying to say? The problems they have don't stop them from posting videos. Problem solving is content and arguable more useful than builds that go 100% smoothly.
@@devonburkhalter9840Ok sorry.
Loving all of the content with Zach getting his hands dirty!
4 piston calipers are great for track use but if u wanna lock up the rear u need less pistons cuz u exert less force to make all pistons fully extend and lockkk.
No idea how you guys are so awesome! Love watching this channel! I wish I had to talent for that!
So for the crank position sensor issue, I've heard that newer sensors are having an issue where there is too much gap between the tone ring and the sensor. Also car wizard just did a video about how alot of new parts he's gotten for customer cars are bad right out of the box.
This has me a little afraid to buy any newer car. After Covid I feel like quality on a lot of items, especially electronics, when down.
All the shortages during covid caused a lot of shady business practices to pump out supply. As a tech, I've seen the new parts being bad alot more recently too. Mostly parts that require electrical components.
Love these troubleshooting and fixing videos btw, keep them coming Donut crew!!
I think it just goes to show you can spend as much money as you want on a car but it really matters on the parts because some cheap parts are just as good if not better than some expensive and how well it's put together
Check in to underdrive pulleys for crank and water pump. You gotta slow the pulley down at hi rpm to cool the coolant down in the radiator
This has turned into one of my favorite series, from you guys.
Nissan and problems gotta be one of the most iconic duos at this point
Subaru and blown engine?
RX8 and compression issues
now that's a tandem!
Nothing problematic had anything to do with Nissan components.
@@focussportyeah, considering that car is pretty much built on everything but Nissan parts.
Lol the 11min mark "im waitin for something to break 🤷♂️ donut "
It makes me so happy every time I see those to cars together
Watching car TH-camrs you start to think your car quirks and issues are unqiue to you. Then you see legitimate car guys like Donut have issues whilst buying the best of the best and get a sigh of relief. It ain't me. ❤😂
They are just youtubers lol not pro mechanics..
Cars are pain.
they have pro mechanics lol, stuff will break on cars, expensive or cheap.
I can tell you're 9yrs old
@@jeffcarrington7411what I thought lol, he’s making it seem like not everyone can be a youtuber.
@@Patient_Lion_BS you didnt even understand the comment. Why are you calling someone else 9 yrs old when you yourself have the mental capacity of a toaster?
Oh boy am I excited for the Zs to be back.
I test drove one recently and it was pretty damn cool. And I just finished the Initial D battle with the Z and the fog and all that.
THIS is the content I'm here for! More hi /low ( specially the Z:eds ) please
good job Zack and Adam!
ps. to the guy who thinks of the description for the hosts real funny stuff!
I feel like a proud (poor) dad whenever watching the bois succeed. I love you too.
Guys, this video was awesome. The editing was ON POINT.
Good shit guys!!! The pure joy of getting it done finally 💪
They needed a veteran mechanic consultant with experience building drift cars from the very beginning. But having a broken car is great content, so it's a win win.
it always excites me seeing the hi-low Nissan Z's again!
Amazing! Also can we appreciate Nolan's 90s double t shirt fit?
In regards to the seal, what can happen is the garter spring that applies pressure to the lip of the seal can be dislodged when installing the shaft causing a leak.
I’ll take the JW kit seeing u don’t need it anymore... I’ve had my ‘04 350z since ‘06 when I was in college… long story but I bought it in memory of my dad, been doing what I can to make it true to the Z line but it’s just a dog compared to newer cars… anyways this whole series has really hit home for me. It told the story of: what I have wanted to do to mine, but could never have afforded to do… it has meant a lot and I appreciate it all immensely
Met James a while ago...he is in fact taller than me...much taller. Dude's like 6'5"
If anyone is looking for the song at 9:41 it's Heyson - B.O.D. :)
I plan on building a 350 daily in the near future and this series has been fun to watch
The trick to avoid overheating is
1. Remove thermostat i.e bypass it
2. Use a bigger radiator if it has space, but use aluminum one
3. Use a performance head gasket to avoid quick heating and it will improve your performance too.
4. Check all the clamps to avoid any leakage
Give it a try
1. Check for leaks and fix if applicable (use a tester kit)
2. Bleed
@@liamflynn6929 yes
first step
100% can not say how happy I am to see you swap over to the LINK ecu. I myself am a LINK customer (04 Subaru Forester XT pushing 425/400). Very happy with their customer service, how easy their software is to use, and just the overall ease of the product to install.
As to the "not street legal" thing, that is ONLY for CA. No other state has problems with aftermarket ECU's. I've had no issues at all with mine, and in fact am converting another car up from the OEM ECU to a LINK (2006 legacy GT wagon)
Last, the overheat problem: Ive had the same issue with a LS swap before. you may need to go to a 3 core radiator with a push fan setup (fans in front rather than behind it), and swap out the thermostat for a restrictor plate (smooth plate drilled with many holes to flow more, but still hold back enough to allow water pressure to be optimal). Going to a plate means having to retune some for your cold start, and having to sit 5-10 minutes with it idling to warm up. Add 5 min if on E85/e98
For the sake of not spending 100K for something you can't drive except on track, I do wonder why they didn't seem to just try a fresh factory ECU if the other one was just corrupted. There really need to be some less-out-of date emissions laws, though, cause especially the older stuff gets, factory isn't even better that way, especially if factory is *worn out.*
@@OllamhDrab CA smog laws/CARB is not about clean air. It is a money making scheme for the state, that also doubles as a way to control the populations actions.
If it was about smog/emissions then they would only judge a car on what comes out the tailpipe, not what equipment it has on it.
@@obiesunstreak2409 Given the difficulty of getting rational politics done, not to mention the polarization, of course what comes out suits the wealthy corporations and dealerships wanting to have a captive market and of course, keep people having to buy new cars when the maintenance gets too pricey. It's not about some 'thought police,' it's about who wins when things are made a tug-of war. (Yes, the money.)
@@obiesunstreak2409 *adds after market ecu to electric vehicle.
"Hey that's bad for the environment, oh wait..."
@@tbunreall EV's are not real cars in the first place, just glorified kids power wheels, toys that have no place on the road.
Watching crank/cam position sensors on an oscilloscope can be a lot more informative than a simple ohmmeter test. The scope can tell you if there is a clean signal or a noisy signal - which ECUs (stock or aftermarket) can't interpret.
Their ecu has a trigger scope built in. Very handy.

I'm not sure where to post this so I'll just post it here. Every time I watch a Donut video I always feel like I want more, like a longer cut. I think there's something to be said about these relatively short cuts; they definitely keep the energy high and keep the viewer engaged for the entire duration. The editing itself is great, the material is presented in a cohesive beginning-middle-end kind of way. But, it would be great to have an option for people who want a more extended cut that goes into more detail, especially on the troubleshooting parts.
Another example I can think of right now is the video a few weeks ago about the drive in the off-road camper that broke. That obviously took days to shoot but we only got to see like 15 minutes of the entire excursion, including the follow-up to rescue it from where it broke down. It was entertaining but there must have been a lot of content left out that I think a lot of people would be interested in seeing.
I don't know, maybe get on Nebula and put the longer format stuff there if you're worried about the impact longer videos will have on what the YT algorithm does with the channel.
Never gonna forget the joy i felt going home on a Friday on the 605 north to look to my left to see low car on the trailer going south stuck in traffic
Has to be the ECU because I have a MAP sensor code with my VQ and changed sensor twice.. but it doesn’t affect the engine performance at all surprisingly.
the problem is that it's $100,000
Your like the only person I've seen comment on this. No way they have rep wheels and it's a 100k car. Not that I care how much it costs or that they're on reps. But really? 100k and this is it?
I'm really confused on swapping of the rear calipers. With the increase in size, the fluid pressure should remain the same if installed correctly, right? Is there a proportioning valve within the big brake kit that needed adjusting or removal? Were the calipers defective? It also looks like you're using both hands still to throw that handle back.
Love the builds! Just very curious, and information other than "not the right brakes" would be appreciated!
I also thought this. That or the willwoods needed a good bleed and top up of fluid to work to their fullest. Who knows eh
Vroom squeak is usually a bad and scary noise, but today it was an awesome noise.
Hope you can figure out those overheating problems, awesome car.
Donut is just goals bro
imagine if after all this work, you guys crashed it
deadass
They get a DUI in it
Ahhh yes imagination
That steering wheel looks like it's been in a wreck or two
Don’t let James drive it.
james needs a pit bike for the track hes always on that bicycle
Should probably wrap the exhaust and the turbo and then even cut some holes in the engine tub that leads to the inside of the fenders that'll help with some air flow
I'm not even into cars personally, I don't know ANYTHING about them but loving these videos from Donut (and a few other channels) so much lately, it's just a whole bunch of friends having fun with cars and enjoying their time.
I just wish when they make build videos theyd give a retail price for things, so if somebody wanted to do any of the mods or mechanic visits themselves theyd have a rough estimate of what it might cost, which could be cool.
in the hi/low series they do
@@KompadoodleLEL yep do they, but I meant more in general for all videos, just like a on screen reference or something doesn't have to be a big point.
Yo, any time you guys shit the bed but then come back and accomplish what you wanted, i get goosebumps. Its amazing watching your videos 🎉
It must be nice to have a car and see the mods you want and actually go and buy them all at once. Especially nowadays I've been wanting to lower my car do a whole bunch of other stuff but things are so expensive that I just can't set aside money for it
I have been running a Nisstune chip in my 180SX since they first came out. It's an easy mod and can give me all I need as it's a street car but for sure if it was track I would go Haltech or a Link ECU.
another win for nolans low car❄️
Day 395 of asking James to do and Up to Speed on his Dad
yes comrade
Glad to see shop daddy Adam gettin some scenes. I know it’s pain, I know it’s pricey, but more more more of this content! Thanks Donut Ladies n Gents
You guys need to do a “car culture around the world” series!! I think people would love that
who dont love the nissans problems
A donut media build car is having problems?? 😱 😂 i would have never guessed...
Can't wait for the next episode of "why does high car overheat" and "will more money fix this overheating problem" love this series
The best part of this video is Jobe saying “Maybe we screwed up the rear main seal on install” while it split screens to a flash back of them definitely screwing up the rear main seal on install lol.🤣😭
Low team on top💪🏻
We need another season of Hi-Low! Do something with American Muscle! :,D
Zach is by far keeping me on donut! Real hands on and knowledge just makes him amazing haha not the idiotic acting the other guy does
You guys need to try vacuum filling the cooling system. Seems like you're having trouble bleeding all of the air out. Vacuum filling will make sure there is no air in there to begin with. The tools to do it are cheap and very much worth it
you guys out there keeping the ol fast and furious spirit going!
The Stocky cars are going to be most of what I give my nephews for Christmas. They absolutely love these cars…..so do I. My daughters have gifted me 3 of the Stocky cars, they are great Christmas gifts.
"I'm just waiting for something bad to happen, cus ya'know, donut" OOF I felt that James.
Yall extra with the background music at the end, but I love it 🤣
You must run the car with no hood foe over heating problem. Adding the biggest badest most fans you can fit on the radiator. It may even require holes in the bumper for more radiator air flow. That big V8 makes double the heat in that tiny engine bay I have seen these problems pulled my hair out then removed the hood. Love yall for real thanks for the content.
8:59 but you can try using one for a submersible... but I've heard that when it goes bad... it can be a crushing blow, makes you want to implode if I'm honest
Honestly, like 5 problems after such a time crunch for high low and especially the amount of parts thrown into the car so fast, any build is gonna have its quirks and takes time to iron them out. Hopefully get to see high car again! I love the trouble shooting vids
You can buy speed bleeder caliper screws that have a check valve. 1 person can bleed the brakes with them.
This was a cool watch thank you.
At around 15:09, make that a poster and sell it! Would look nice next to my Ken Block Gymkhana 3 where he's drifting vertical in that autodrome and I can't believe I'm unable to find an image example of that in Google. Might have to take a picture of it myself so that it lives on.

“No lube or nothing dude I knew you were different” 😭😭😭 5:57
you'll get more cooling efficiency in a car that never sees cold weather (like a track car in southern california) if you run distilled water with water wetter instead of antifreeze/coolant, which might help with the heat issues, but heat is pretty much always going to be a concern in a drift car
also suede steering wheels are for driving with suede grip gloves, if you drive them with bare hands they get chewed up like the one in hi car is
