Finally a video that isn't 20 years old and with the disassembly in view. With an explanation of what's being deleted and how it's being done. hank you :)))
You're welcome!
One thing I've learned over the last 25 years working on cars, if it feels excessively difficult to do a job, you're not using the correct tool. There are tools for every type of job to make it easier, sometimes you just need to take a step back and evaluate what the proper tool is that the job requires. Keep up the good work!
Excellent content guys, love the team spirit, working in a single garage,
Humble beginnings
I am proud of myself. I did an egr delete on my 300zx with the motor in the car. Thank you guys for the instructions and steps on removing it!!!
Just got a 60k mile 96 phase2 , and you just made it a whole lot easier for me to do these mods in the right order. Thx mate
Love it and good luck!
You guys are killing me. I am literally going to attempt deleting my EGR with the engine in the car. You and Robbie basically walked me through what I need to do. Thank you so much -I needed this! Keep up the good work!
Love it! Good luck and take your time!
You guys rock. I just learned how to take off my plenum to fix an injector o ring. Love watching your videos, makes me want to learn to work on my car more and bring her back to life ! Thanks for being so inspiring !
Love it! Thanks for the support!
What did u use to cap the PCV delete at 13:07?
Feel SO much better about paying my Z mechanic $850 to do this very thing. Money well spent! Hats off to you guys for doing it and making this video.
no lie yur the best bro. Like.. can't even put into words how much uve helpd me in the last year
Thank you for the support!!
Couldn't have done it without you, I do appreciate it.
Well as you said, it can be done with the motor in. I just completed the EGR delete. Really was not that bad, it took several hours, but I didn't break anything and I am not bleeding, overall, I call that a win. One thing I did to make it easier to get the tube out of the exhaust manifold was to remove the master cylinder from the booster. Being careful not to bend the tubes too much, I moved it a little up and back toward the firewall. Access was easy after that. Also, I only removed one of the hard coolant lines, the one that is on the left if you are looking at the back of the motor. With all the other items out of the way, it should be fairly easy to reinstall. The one directly on the back of the motor, on the right side, was too difficult to reach, you cannot see the bolts, I suppose you could use a mirror if you wanted too, but that was going to be my last resort if I couldn't get the tube out. I would not recommend removing this one if you don't have to. I had to cut the hardline that connects to the bottom of the plenum on the passenger side to get the line out. After that, it slid right out. Also, the bolts that hold the EGR in are too long and must be left in to remove the unit, this was mentioned in the video.
Question: Is there another video of how to put it all back together? I am sure I could figure it out, but I love a good video. You may have one out there, I could have overlooked it.
Once again, appreciate it, I watched your video several time to get me thru it, overall, most excellent.

I bought a cheap ace hardware 22mm wrench and cut it in half to fit it under the brake master cylinder fore that exhaust pipe, worked like a charm
Good Job guys I have z31 not Z32 but its all good lot similar tho. You explain step by step which is great good work so far. Looking forward next video.
Thank you!
Very informative video thanks Z-Bruhz
Love the puppy print @12:50
Sorry to be comment 70 but your vids keep coming in handy for me and I really enjoy the thoroughness. I just wish z1 and the other z shops weren't still so expensive for these little seals and gaskets, I mean $6 for each of those tiny injectors seals seems high to me.
I feel you on that! But it definitely is a supply and demand type of thing
This is going to help me alot
Love it!
Wish I had friends like this !
I am super thankful for them and have the best in the business!🤣
nice vids man
Thank you for the support 🙏
I just got my motor back in after doing the same thing. My TT has been sitting for almost 6 years. I live in MA and we should meet up this summer.
For sure!
Are These the exact same steps for the tt?
Appreciate your video’s. Looking for advice. I did these deletes. Now the engine will start, sounds good and then idle drops,stalls and dies. Will start back up but repeats. Thoughts?
Your videos are great.. help me a lot to work in my 92 z tt.. quick question.. I’m on the middle of swapping my engine.. and im curios about deleting egr and cooling lines… can you tell me about it? Pros and cons ?
I have a question how do I go about plugging the exhaust valve covers can I just plug them with rubber caps or what’s best to plug them?
Z1 is expensive I like concept z
I live just up north from z1 so i have to gotta buy from them but i’ll start buy czp pretty soon
Currently doing this to mine, while the engines in the car.... Fun times
Good luck with the build!
@@ZBruhzchannel Thanks, I am more concerned about all the bleeps ill need to edit out in my video next week haha
EXCELLENT......
Hey I just delete everything and this video was very helpful I really appreciate, now I have a question, went I put back together I will have any check engine light?
I never had one and did it on two cars
video made on my birthday lmao and i own a z32
Great video. I found a TT sitting for 16 years. Doing same - just rebuild injectors and basic stuff. QU. Deleting the PCV system worth it? EGR going - too complex and emissions not such a big deal for a collectors, water lines gone, great info. TT bit different but ur vids are really good.
Thank you and we think personally that the pcv system is just a part that fails within time. By deleting it you will. Ever have to worry a out it again!
I have an NA I’m starin at in my garage rn fully stock if I delete coolant line and egr what are pros and cons thanks 🙏
Is there a available block off plate for the aac module on the back of the plenum because it’s pretty much useless with out the iac correct or am I wrong?
Your video was SUPER helpful and I pulled my VG30DE this Saturday. I am following along with your build carefully and am currently building my carts with Z1 and CZP. I am curious about why you opted to not move forward with the FULL Engine Gasket Kit or ge the Z1 silicone hoses. Trying to decide what to get while the engine is out and welcome your feedback here or via DM. Thanks!
I didn't do the full kit just because of money and time, I did the most cost effective and efficient kit that I thought would fit me best. Personally I wish I could have done it.
The gasket for the 2 heater pipes on the back side of the engine by the EGR…do you have a part number or do they have a specific name? Thanks.
Thanks for show where the egr thing goes on the headers but can you show us how to delete and cap prvr and aiv system
That will be coming up later this week! Stay tuned.
It’s awesome that you do the delete. I am in the process of doing the same on a ‘92 NA. By looking at the video you mentioned about cutting the coolant lines but then it seemed as if there was nothing there when you were done. Do you have an actual picture of what the engine looks like with everything deleted? Also once you are done we don’t see you do anything on the mounting as far as what needs to be deleted around the fire wall and the completion on the final installation. Is that on another video that I don’t know of. Thanks
If you watch our later videos there should be some bits and pieces where I show what we in fact did.
A very informative video! tho why wouldn't you just be able to plug the valve fitting on the exhaust manifold? and avoid taking the whole egr off
Egrs cause issues, and with the entire module there i believe I had a rats nest behind it so I wanted to clean all of that out and check my knock sensor out.
Man , I need a friend like robbie haha ! I have the parts to do all of this but having cold feet about digging into it . Do you have to do the pcv deletes with the egr? I was going to send my plenum to a shop that shaves and welds everything clean for the deletes .
When removing the egr, what are the sizes of the nut on the egr tube? You said 22mm for the driver's side manifold but what about the one by the egr itself? Im replacing mine on a 90 jdm tt. Thanks.
The bolts holding the egr to the engine are 12mm, the big nut is 22mm, and the coolant piping that is in the way is 10mm I do remember seeing someone saying they used a 1 1/8 in. Wrench for a different nut but were not specific about which one
So do we need to cap off the lines under the throttle body? This is a little hard to follow since I plan on keeping my PCV system
Lines under throttle bodies need to be capped off
Is there a way to just deactivate the EGR system but leave the valve and the piping in the car? I'm into my TT and I'm down to the valve covers. I'm going to do the coolant delete, the PCV delete and the EGR delete. The lines off the coolant tubes you were talking about cutting and welding shut are used in the TT for the cooling lines that run to and return from the turbos. I did the EGR with the engine in the car and the plenum off. I had to remove the exhaust pipe on the drivers side, the pipe from the turbo to the exhaust. That is how I got the 22mm exhaust tube out of the driver's side exhaust manifold. I had to remove the driver's side coolant tube from the back of the engine to get at the EGR. You will have to get the two bolts that holds the valve on and the two side pipes that run to the underside of the plenum. It was a pain, I think it took around three hours and I have a lift. Thanks for the great video.
I don't believe there is a way to just deactivate it unfortunately. Only thing I've ever seen is completely removing it
After seeing how unnecessarily complex the VG is (I got a Z32 TT), after doing the 120K service (in my garage), I'm going LS. I hope you guys do the same or go 2JZ. That VG is a pita! I'm in California too, where the motor swap and smog laws are stoooopid strict. But you guys are in a different part of the country where it's much easier to get by on.....Go LS. They're cheaper to build than VG's or VG30DETT's. 400 horses on the dyno with relatively little effort.
Definitely very true but up front cost can be from 5k-8k for a full swap. So for me until the motor blows up ill stay VG for a while haha, thank you for the input though!!
@@ZBruhzchannel True. Ride it till the wheels fall off.
friend I want to know if Mitsubishi camshaft sensor is compatible for Nissan 300z
Many have asked this and I do not know, I haven't had experience with swapping them out unfortunately
Was doing my clutch and never really gave much thought about deleting the EGR before. But when in Rome always delete your egr
Well now I’m scared xD might have to wait until I do my motor swap to do all this on the new engine rather than fiddling with it all now. I have a tendency to break stuff lol
Hahaha
So after doing all the deletes, Egr the aiv cc do I leave the sensors disconnected?
Harness should be disconnected and tucked away
is there a part number for that pcv pipe thats connected to the valve cover? i’ve been trying to find it but i havent been able to figure out an exact part number
if anyone could help me out that’d be great. i bent the pipe a little bit too much dont ask me how lol and i need a new one to replace it. need to know asap !!
Is their any cons with this..I'm gona be doing that to mine and I'm new to the whole scene
I haven't had any issues. It does depend on where you live and if you need to pass emissions. Besides that it's just simplifying the engine and removing things that commonly fail on our cars
What are the things in upper right on the video thumbnail?
Egr delete plates
Do you know if you can pass smog with coolant line delete in Cali?
Yes you can
So that cluster of hard lines that was stuck on with a bolt while you guys tried to yank it off doesn't even need to be there at all?
That us for the pcv delete, but only as long as you remove the ports on the drivers side exhaust valve cover then those lines can be deleted
Ok quick question. I bought some headers used from eBay and the part where the EGR threads in is capped off with some gnarly puddy inside as well. Can I just cut off that one pipe that goes Into the headers and cap it for now? I have the transmission out of the car and currently have access to the whole rear of the car EGR assembly. P.S. what a nightmare doing headers was with the engine in the car OMG 2/10 would not recommend
I would say if you have the transmission out I would try to do the complete job correctly. Just because if there is any vaccume leak the car will not run right at all. I always say do the job once and never worry about it again
Will any of the plenum deletes coolant wise effect the egr
No, coolant lines are for coolant not emissions
I would replace the Knock sensor and sub harness now while the engine is out. As they do fail. And replacing them in can is b...
Will do! Thank you for the insight!!
Bro do you have to take the plenum off for coolant line delete?? Cause my lines is squirting and it’s making my car over heat
Definitely pull the plenum man!
Hey guys , I was wondering if deleting the heating hoses will affect something in the ac system, I’m trying to learn here, currently I’m deleting mine but I was concerned since those hoses go into the firewall. Please advise, thanks in advance.
The heater core are the hoses that come through the firewall. If those are deleted, you will not have heat. The AC component is a separate system.
What's the purpose of removing the coolant lines for the plenum and the EGR?
The coolant lines tend to burst due to the age of the car. Many rot away, and the main purpose of them are to warm up the throttle bodies on cold days. By deleting the egr the car will be able to breathe a lot better. Over years the egr can clog and cause issues within the motor.
When deleting the egr , does the pcv system also need to be deleted?
No they are two separated deletes but mine as well do them both
I have a question I’m trying to do the egr delete this video has motivated to do it but my concern is by doing the egr delete will it trigger a check engine light?
No it will not
Awesome!
Your videos are great n detailed so many things I’m going to try on my Z!!
Thank you!
I’m wondering what’s the point in doing these deletes? What purpose does it serve. I just bought ‘95 300zx and I want it to last me as long as possible
Deletes make the car simplified aka less parts to fail down the road and some deletes like the egr and air allow the car to breathe easier
what are the reasons to delete EGR and plenum cooling, and what are the consequences ?
Deleting the egr is one to make the system simpler, along with helping the engine breathe better with not having to deal with excessive amounts of carbon build up
Buenas tardes Buenos días buenas noches amigo le estoy hablando de Acapulco Guerrero México lo cual yo tengo un problema con mi Nissan 300zx no puedo encontrar la bomba de aceite con el diametro de 44 mm en el engrane de montaje si hubiera una manera de que usted pudiera proporcionarme número de parte con esas dimensiones se lo agradecería mucho Gracias Enhorabuena
What's good
Quick question, when you remove the intake coolant lines, we’re you able to route your system so that you still had your heater? Or you completely deleted it?
?
When you remove the intake coolant lines you just cap them off, but you can leave the heater core lines the same as stock
Removing the coolant lines under the plenum does not affect the overall heater core. You just cap off whatever was running from the heater core to the deleted lines and good to go!
I have questions for my 91 TT what state are you located?
We are in MA
where are you guys from?
If you remove the 2 coolant hard lines, you mentioned resealing them. What do you use, just rtv?
Yep rtv is the best way, there is a new kit out from merlin machining I believe to where it's an adapter and you can use O rings instead
@@ZBruhzchannel thanks. I'm doing it as we speak with the motor in trans out so we'll see how it goes. Probably will be cutting a lot
Is that injector sale still going on from rock auto?
I do not know unfortunately
Where are you guys located? What headers did you get
Located in massachsetts, the headers were an off brand on amazon
How are you going to smog the car? After EGR delete
Massachusetts does not test for smog
@@ZBruhzchannel Cool
Why would you delete those coolant line from the throttle body and onward wouldn't that hurt the performance?
No this does not, engineers applied these lines to help with cold start ups to warm the plenum and throttle bodies. Good idea, but unfortunately for old cars things break and corrode and by deleting these before this happens save a future headache from happening
Ima get one so im farely new to this but whats the point in deleting it
The point of deleting the coolant lines is within time after all the heat they see iver the years they burst and it is a pain to get to anything else when they are still attached. To delete the egr this will help with having the car run more efficiently and give the ability for the motor to breathe. If it has never been done you will see some black sludge within the ports of the egr and that causes issues.
@@ZBruhzchannel thank you 🙏🏼ima probably do it then
@@ZBruhzchannel the one ima get is a 91 tt but the motor is out rn so i might as well do it
Do 1996 300zx’s have aiv? I deleted my EGR and I’m getting a rough idle now but it drives smooth. I have a brand new wiring harness made by wiring specialties, have new spark plugs and injectors installed by Z1. Cylinder 3 has been slightly misfiring at idle and I swapped COP from 3 to 2 (which is a working one) and it still misfired on 3. This leads me to believe that either it is something bottom end, which makes no sense because it drives fine, or it is MAF, or AIV not being fully deleted. I did not cap off the front like in this video only because I’m not sure if I have AIV’s. Thank you
Know it's late but on the 96 you can't delete it
@@lgrc11 actually you can just fine. mine just had a loose MAF and needed a new wiring harness custom made.
How much was the harness
@@lgrc11 $1200
@@lgrc11 the issue was actually a mixture of incorrect fuel injectors an incorrect hookup on coil packs to EFI. I ended up getting it sorted out finally.
How is the car attected when you delete egr and pcv?
Great. Never been better
@@ZBruhzchannel Nice! What about exhaust emissions, do they increase? I live in Sweden 😊
@@johanbergqvist5357 that I could not tell you, in Massachusetts we don't get emissions tested anything over 20 years old
Dude never go cheap on motor mounts you'll end up doing the work twice and paying twice might as well do it right the first time the reward will be peaceful mind and quality u won't get from cheap ebay motor mounts trust me been there
if you delete the egr do u have to delete the coolent lines?
No but if you ate already there mine as well
@@ZBruhzchannel thank u so much man. plz keep making videos lol u basically my only teacher
@@mahmoudlihmeidi4657 love it!
Where is episode one?
It is the nissan overhaul installment 😉
muy buenas noches o días para ti amigo hace un tiempo y a ustedes le pedí un asesoramiento y me lo hizo hablo de Acapulco Guerrero Tengo un Nissan 300zx Norman aspirado el punto es de que no me sirve la bomba del aceite compré una era totalmente igual ver el orificio para poderlas montar el cigüeñal no daba el resulta que era muy pequeño de trabajar un poco más grande no sé si usted fuera satelitalmente el número de pieza original brazo media exacta la que yo compré el orificio que embona en el cigüeñal es más pequeño Necesito que sea la que tienen el orificio más grande De antemano muchas gracias y le agradezco si podría apoyarme en este aspecto con el asesoramiento se lo agradeceré de todo corazón desde el bello puerto de Acapulco gracias joven y que pase un buen día
Bruh I was gonna comment.. why the fuck he using a line wrech on a bolt... lol then he says he couldn't find his box wrench lmfaoooo
I bought this stupid car as my first... And i live at a condo complex so i didn't have a garage. I had to delete all those lines and EGR in the car and now i feel like i can work on any car😭
