86 Nissan D21 Vacuum Hose Delete, and other stuff
HTML-код
- Опубликовано: 8 сен 2024
- Just a quick walkthrough of all the emission components and vacuum hoses I've removed from my Nissan D21.
She runs quite well considering the mileage (200,000+), actually runs better after the removal of the Vac Hoses (before that the engine would surge a bit then idle down, continuously while at a stop light or stop sign.)
Yeah i did the same thing with the vac hoses. I just traced where they went and if it was non essential i capped or removed. And some rust did some removing of components for me as well. i took about 20 feet of vac lines out that were just going nowhere but back on themselves lmao. Truck runs great now besides a bad fuel injector that I'm about to replace. Oh and lifters are noisy I might go in and adjust the lash. Eventually I want to get a standalone fuel injection 2 or 4 barrel system and build an intake for it. Or if i get a chance just swap a 2.3 ecoboost in it.
Mr Woody that's awesome, man! Glad it worked out for you! :)
I'm glad deleting all those hoses worked out for you! It sure does clean up all that unnecessary clutter! Lol
Good work Ralph. ❤❤❤
I did all that on my nissan 86 d21 did not pass the smog i have to put everything back and my gas millage was terrible 😢
Sorry too hear that. The egr delete is mostly done in states that don't have emissions. I live in florida. They don't have emissions here.
Im looking for the plastic cap that holds down the throttle body air filter - anyone have a spare ? Its an 87 D-21
What car did u get that Intake hose off of? And what size air filter cone is that?
Sorry. I don't remember what car I got the hose from. This was a few years back. The filter I'd gotten from auto parts store. Don't recall the size. I've since removed the throttle body and installed a Weber carburetor. So the setup isn't the same anymore!
It came from an 86 Nissan 200 sx
I have wires hanging from a lil behind my manifold idk what they r
Nice video mate. Does this affect the idle ? Like higher revs at idle? Should this give better gas mileage?
I honestly don't remember! It's been a long while since I deleted the vacume hoses! I want to say the Idle did improve! It used too surge up and down at idle, but would normalize when accelerating!
I can def say installing NGK wires, NGK ignition coils and iridium spark plugs greatly improved overall performance and especially gas mileage! I think the truck used to get around 16 miles to the gallon or less?!...after the ignition upgrades, it jumped up to between 27-30 miles to the gallon?!!
That's the anti back fire valve and is very necessary
That's exactly what happens the manufacturer put it there for a reason. Example if everything he took off. Cust 100.00 dollar and Nissan made one million trucks would they spend 100.00 million dollars if if the truck didn't need it. Well that's what they told me at Nissan school.
Can u make a video without the air filter off . im trying this set up on my 87 niss pickup
Dee Bernal sorry, I'm not quite understanding your question! If you could rephrase it, I'll be more than happy to upload a video of your request! Sorry for my lack of understanding!

Where u locate bro I need to do this for my truck I can pay to u
@@adrianmejia4997 I'm in Florida! Where do you live?
@@almagam2099
Oops I'm in California well appreciate u reply bro just one more ques??? How is Florida with the emissions laws please let me know
@@adrianmejia4997 no worries! Yeah, there's no emissions down here!
Is this the fuel injection carb z24i
Yes. At this point she still had the fuel injected throttle body. I've since installed a Weber carburetor.
Was it worth it?
@@samwhite1345 yes. When I was first removing the throttle body, most of it's components were very brittle. Parts were crumbling apart as I was removing them.
It was the same with all the emissions stuff. The Weber helped do away with all that. Plus it helped open up the engine up a bit. I'm not winning any races, but at least now...she's only slow. And not slow as molasses. 😆
That's awesome I wasn't aware that you could convert the EFI to the Weber I have a 720 z24 that I'm trying to find a conversion for and it's been a pain
@@samwhite1345 yeah. It's a great alternative too the stock throttle body. Plus the Weber doesn't need any of the tbi sensors or vacuum lines too work
Lol. This is hysterical.
Any problems come from doing that yet?
Thankfully, she's still running good! I actually had found a forum where they went into great detail about removing all the nonessential Vac Hoses! It was incredibly helpful! I'll try and find it again and I'll post a link to it here!
I still need to look for or somehow fabricate a smaller air-box as the stock one has a port at the bottom for a vacuum hose that I removed! I'm not sure, but I think that open port would have the same effect as a vacuum leak?! also that air intake hose I added to the air-box isn't air tight! It's on there very snug, but it's essentially another spot with a vacuum leak! Other than that, removing all those Vac hoses really improved the overall performance of the truck, plus I also did your basic tune-up! The only thing I haven't done, is replace the old spark plug wires!
@@almagam2099 , did you find that forum?
@@ericjackson478 this is all I've been able to find! But I'll keep looking! www.infamousnissan.com/forum/showthread.php?t=17480
@@ericjackson478 most of the forums I've looked at, at least the ones with photos, the photos are no longer there!
I have an 86 and a half Nissan longbed... Im interested in selling if anyone is interested 299.999miles sits as non op fires up and runs.. Email me at cockedoutclothing@yahoo.com
Would doing this still allow it to pass smog in California?
Sorry, but no! I don't think it would!
What about the pcv did you delete that also
Benji Hunter sorry no, i haven't done that! Would it be better to delete it or replace it with a new one?
Benji Hunter I ended up taking off the pcv valve after work yesterday! It was fairly dirty and grimy, but otherwise it was in really good condition! I cleaned it really good and reinstalled it! So far the trucks running good!
Thank you. I thought I could run my '87 Pathfinder without all that vacuum hose. I tried pulling them off which ran bad. Looks like capping the ports is the important thing. Big difference in '86 to '87 motor types, or there's a chance mine may be a "90s motor.
Yeah I learn't the hard way there's a big difference between the 80's and 90's motors! I'd started removing hoses on my 93 Nissan (big mistake)! It's fuel injected whereas the 86 is carburated! I had to put all the hoses back!
@@almagam2099 its not carbureted its throttle body injection
Want to Delete all unneeded Vacuum lines, canisters smog do-hickeys!? But, if the video can't identify a(Air cleaner canister) EGRs, the thing that was there now on the ground how can I know makes sense of what I'm removing or not ? I came to the site for info! On deleting ?? That thing on the ground that you took off the drivers side looks like a Brake Vacuum? Is it smog ? And that hose U removed but put back on because it ran bad?A lot of mis informed & I'm already that.
I'll try my best to find the forum I was on where I first learned about this topic! It was very informative with photos and description! I do know that it's far easier deleting the vacume hoses on a carbureted vehicle than it is on a fuel injected one! I was merely showing that it can be done!
The round one is a valve that takes exhaust and puts it into throttle body for some reason. I saw the anti backfire thingy that usually sets on a mount with it in the dirt. the tall black one you capped off is a canister of charcoal that's not "needed" also has a filter in the bottom should be serviced 15k miles wasn't in the manual. it will leak on stuff I have heard.
Hey it’s me again any chance I could ask a series of questions tomorrow about this😅 I ran into an issue I think
Sure thing! 👍
Will it still pass emissions testing???
Sorry! No it won't pass emissions testing!
@@almagam2099 I have the same truck and here in California if I want to continue to drive it on public streets I can’t do any of those modifications you did.
Man, that's a bummer! Sorry too hear that!
Why is this necessary?
Is and isn't! On this particular model "carbureted engine" most if not all the vacume hoses are obsolete! The main reason I did it, was when I got it from the previous owner, pretty much everything the hoses connected too, were in really bad shape and crumbling too the touch! After a bit of research I found a forum on the subject for my year, make and model truck! I've tried searching for that exact forum as it was incredibly helpful and detailed with photos and explanations on the entire process! But no such luck!
@@almagam2099
Could you post the link for that forum? I have the exact same engine and want to delete the same part, but I'm not sure how to do it and what I can touch and what I can't.
@@oswaldorodriguez5728 I'll try my best too find it!
@@oswaldorodriguez5728 I've never been able too find the exact forum for the egr delete! But here's one that does have photos and explanations on all the vacume hoses and where they go! Hope it helps!

Man, thanks a lot. I appreciate it.
I'll check rn and post back any issue or improvement I notice.
Again, thanks a lot! 🙏🏼
🤔
I guess it wont pass smog test now.
Prob not! Before I installed a new oxygen sensor, the smell of exhaust was really strong! But now it's barely, if at all noticeble!
