That "cold air intake" you showed was really a hot air. The stock intakes pulls air from the fender well. I know the aftermarket ones look cool but stocks better.
Just a heads up on the headers mentioned for the hardbodys. 99% of the cheap headers out there are for the 4X4 variations of the D21. They will NOT fit the 2wd trucks without modifying the headers and smashing your firewall in so that the headers can clear. Im speaking from firsthand experience.
What about 240sx Headers? Same block different manifolds and heads I believe.
@@curtfox91 the flanges are the same, however the 240 headers are too long and will bump into the torsion bars as well on the d21’s. 240sx’ didn’t have torsion setups so you’ll have to chop, bend, and make em fit.
Yep only choice is to get the expensive 2wd header.
@@seanholmes8290 correct.
I just ran into this on mine I ordered the header and it was unspecified wether it was for a 4x4 or a 2wd and we put it on and it hit the cab and the torsion bar but we cut re angled and welded the header and now it clears everything and has room for the pipes and muffler
Also of you have the truck, get an intake from 240sx..power gains easy
Nice truck. I have a green 96 extended cab 4wd with a custom flatbed and 5 speed. I rebuilt the engine a couple years ago for a total of 1500. Thats including a slight overbore and a new crank. It's so fun to drive. Imo best mod to do first would be shocks and decent wheel/tire combo to match what you use it for.
Ive been meaning to put a flatbed on my 95. Did you use the original mount points? What did you do with the taillights?
44 thousand rpms… 44hunnid. But love any kae content.
Yea i know lol 😂 cant go back and fix it i heard it and laughed cause i knew someone would mention that part.
Hey if you do the timing chain. Make sure and get the auto adjustable tensioner
Or do what I did and just cut a 1/4 chunk of a m8 bolt and put it inside the chain tensioner ram/in front of the spring. Put the chain on first then bolt the tensioner on. If you can't bolt the tensioner on or the chain is too tight, then shorten the spacer/bolt that is inside the tensioner. Do this till its just right and it works great. This way it has a taught chain even with the engine off.
I actually bought the MR.Jim spacer for the chain. One day i will get an auto adjuster.
Heres an update on my truck. It's still running and I got the auto adjuster and installed it with the rubber plug on the timing cover. Copied what Mr Jim did in his install video without pulling the front cover by drilling a 1 1/2" hole where the tensioner is. Now I have a new issue that i thought was chain rattle, its a collapsed lifter and it ticks when its hot. Happened after shifting at redline and it backfired. Looking into getting the mechanical lifters and matching cam from O&J so I don't have to deal with the hydraulic ones that always fail eventually.
What is this music!? My god I never thought this level of cool was possible
Which timestamp? Id have to go look them up
4:13 Never understood that mod. You are going from the "Colder" side of the Motor, to all the way across the block "Hotter" side for "Cold Air" . Mine stays on the Left Side.."Coldest" side of the Motor.
Lol im so shocked people actually watched this 😂 . Yeah I leave my Intake stock from my experience my cars always felt slower.
Glad I found this channel and video. Just bought a '95 XE and was thinking about what mods I can do, as it is stock. One main issue I have is not the engine. I cannot seem to find a 6ft. tonneau cover for it. Any ideas?
four thousand four hundred or forty four hundred you added a extra zero I wish it spun 44k but great video just breaking your balls
2:17 I don’t think they’re cheap anymore I have a 94 Yota and was just looking around for 22RE’s and they go for like 2,000 now so I’m sure the KA24E is about the same
I dont think the KA24E will cost as much as the 22RE. But wow that’s insane. Overtime all of these trucks and Engines will be so rare to have
Stil can get a ka24 in New Zealand for $300 bucks and 22r for $500
@@curtfox91lol how this has aged
44,000 RPM. Nice!
Yeah yeah your not the first to say that
I don't have the D21 I have the 720. A swap may be in my future
Any recommendations for headers and a turbo kit, I got a 89 240sx that imma start modding
Obd2 plug ins don’t work as our obd2 ports don’t work, there a fake plugin and would still need to use a Nissan-2 diagnostic plug, as well as dyno tuning, these ecu’s can’t be altered only chipped so it can’t be changed on the fly. We usually go to Jim wolf technology for a chipped ecu or just stand alone from megasquirt. These engines do love turbos but hate nitrous oxide ka24 as in e and de tend to just fall on there face and blow up.
Also these trucks have a really bad timing chain rattle that develops in later mileage as the tensioner from these trucks greatly relies on oil pressure as the spring in the piston gets really weak. The remedy for this is a self adjustable tensioner, while your at it might as well get the adjustable cam sprocket because these trucks have bad low end torque the rpm these trucks start to move is around 4400rpm.
@@jessedigiovannantonio3656 I don’t know if you watch the video but I mention that in the Video.
I have a Z33 but I’m honestly tryna pick one of these up for a daily and when it blows up put a VQ35DE in it!
Til this day My D21 runs strong. Love it everyday
Best header recommendation?
@@angelpuente9335 which HBO do you have?
great vid
Bro ur funny as hell. Thanks for the guide. Any exhaust suggestions?
4:13 do NOT get a cold air intake just buy a snorkel it'll look a million times better, it'll be cheaper and you can wade through rivers.
It's cold air to start with since all 4WD's get air from the fenders.
We’re do we get the parts from
I have a question. . .
I have a Ka24E engine lying around. What will i need to get it running in another car? I heard a standalone ECU would be great but how would i connect it to the Rx7 Dash harness. Do i connect wires that correspond with one another. I do have the OEM ECU so if i can still use that, that would be great. But if necessary i will get a standalone
It ran before i swapped it for an SR20det so i'd like to use this engine in another Chassis (Rx7 FC, It's a cheap budget drift car. Nothing crazy just something for seat time to see if drifting is what i want to do later in the future.)
All i want to know what's needed to get the engine running when i turn the key. Thank you
I heard many bad things about the KA24E but i don't want to give up on it. Maybe i'll turbo it in the future . . . .
I have no Knowledge of Swapping the KA24E in another chassis besides the Hardbody or the 240sx. Many bad things like what? There’s more good then bad with these Engines there literally bulletproof. Dont take my word but i would assume all you need for a KA and another chassis is Correct Harness and ECU. Its such a simple engine but also these have alot of vaccum components to so i wouldn’t know about that aspect.
Lmk how it goes dont give up on it
@@curtfox91 thanks for your knowledge. I did a bit more research and it does seem like I need a standalone ECU to get it going. I know the motor runs so any problems I run into are mine and not the motors fault.
From what I was told they aren't good motors but that's because the people who owned them I guess didn't give it a chance or are owned by younger people who just want 1jz or other Japanese motor.
But from my research these motors are really good and can put a decent amount of HP.
I'll do more research and then start my swap soon. Again thanks
@@Alex-vz2jz yeaaa boiii 🙌 anything you need for the KA is very accessible. I know people with 500 plus K on theres without rebuilding
1:03 44,000 RPM? What is this a turbine engine?
Check out mine whenever you have the time I have beat the h*** out of it it is definitely bullet proof
Dude you got this thing looking so much better man. Looks good
I did an Egr/vacuum delete in my 97 Nissan Hardbody, after putting headers on it, in idle the RPM’s bounce from 1500-2k constantly .. it’s really embarrassing at stop lights 😅 it’s a Ka24e , any ideas?
Sounds like you have a vacuum leak, so maybe some of the lines you removed are needed for it to run right
Nice! My 91 d21 has a smell coming from under the front end. I swear it’s exhaust but my local muffler shop says there’s no leak. Any ideas?
Not sure. Maybe a catalytic converter is clogged. Could be bad air filter. Valve cover gasket leaking
@@curtfox91 Thanks for the ideas!
My KA engine won’t start, changed fuel pump, distributor, wires, spark plugs, fuel filter, flush coolant, battery, ign coil, cleaned Maf sensor, still not starting
Did you make your timing is on TDC??? It will not crank unless it is.
injectors?
subbed
do you know if you can put the dual fan from the altima
What types of turbos or turbo kits fit on a 1991 Nissan d21?
I dont know you’ll have to look that up yourself. Im sure they have that information on the Forums
none!! you got to piece one together. best thing to do is get a universal kit for intercooler and pipings, rev9 manifold, bigger injectors and a ebay turbo. and tuning would keep it alive so pick a ecu that your tuner is comfortable with
I think part of my timing chain guide broke, will that cause any issues?
If you have a Rattle that doesn’t go away that means your chain. Is to loose and can cause your chain to come off the crank if that happens you can lock your motor up. The best way you can fix is just redo the timing chain and install new guides the newer guides are stronger then those OEM ones.
MR.JIM also sells kits for this he is a D21 timing chain expert. Look up Timing Chain start up rattle.
Bruh there are soo many simple mods you left out for horsepower and torque gains..alot of horse and torque is restricted from the factory..once you open it up and let it breathe, its a whole different animal
This video was a Joke im surprised people watched it. My truck is auto not gonna se much gains in its life unless i get a manual or a 240
Do you work on Nissan Hard Body trucks?
1997 I need just a little more horses to pull Arizona mountain grades,& that's it. Just that
@@curtfox91you can still get plenty of gains with an auto..easiest would be to get an aftermarket ecu, tune, Fuel injectors, fuel pump, and swap the intake for a 240sx intake..easy power. Or throw a turbo kit on it and tune. Auto or not, turbo is fun lol
@@ferrotee2629try swapping the intake for 240sx intake. Should bolt right on, 97' had a ka24e i believe, same as an s13 240sx (1989-1990)..also all these cars have a sohc that you can pull parts from..

@@ferrotee2629and yes i am a mechanic and i work on all things nissan..i have a 240 myself with a ka24e. Most reliable motor i have ever owned..i can drive it to the track with tools, jack, spare rims and tires..beat on it all day, drive it home. And it starts up the next day no problemo. There is just a few things you have to do to make it bulletproof. It has weak points, like the timing chain, notorious chain slap because the guides go out or the tensioner fails, but you can shim the piston on the tension and never have chain slap again. Plus after i did that i noticed the motor was way more torquey and had more power. And the ka motors have tons of blowby, like most nissan motors do(even the hq motors have tons of blowby) so invest in an oil catch can for the pvc system, saves lifes lol
Is this the same on my 2002 frontier
No, Nissan changed it to a DOHC 16 valve four banger pretty similar to this one thiugh
difference of e and de?
Single Cam and Twin Cam
@@curtfox91 twin cam is dohc and single cam is sohc right?
I believe the e is 12 valve and the de is 16 valve also

I don’t think this is a very great instructional video 😂 sorry bud
Its not really a legit instructional video its more like a Parody of one. Just explaining what can be done to the KA24E in lamest terms. But thanks the information is valid and useful thats the main point
Pound feet of torque! Not foot pounds!
Im from Texas son we pronounce things half ass sometimes. Sorry to hurt your feelings
i don't think Nissan has ever or will ever put out an engine in a car or truck that will EVER handle 44,000 RPM.....
Yeah Yeah lol your late to that party
Nitrous is non flammable 🤨
Hey why dont you talk to Johnny Tran
that is not a KA24E motor .....that's a KA24i ....cause i designation is for TBI engines
Wtf
