SR/KA "Shorty" Hybrid Trans Build | D21 Drift Truck - Ep. 8
HTML-код
- Опубликовано: 15 авг 2024
- In this episode I will be configuring the D21 KA24E factory 5W71C "short" transmission to accommodate the SR20DET engine using the SR bellhousing and SR shifter link extension. I will show that you can adapt an SR/KA/CA/RB20 short throw shifter to the rear section of the D21 transmission. Episode 9 will be the mounting of the SR.

Wow! Really informative and great video! ik im late to watch it but great info for future CA18 D21/ KA24 200SX :))
Nice! Using this info for my sr20det to ae86 build. Thanks man!
Good job man, I wish I had your knowledge!! Im looking forward to next video! Thanks
Quality videos as always!👌
Holy shit. Thats very simple. Not bad at all
Thank you for the "Knowledge Bombs". Coming along nicely.
Thats a crazy build bro😎👌🏼

Hi, I'm searching stronger and cheap gearbox for my worn gearbox in my SR20det (about 320hp). Friend of mine told that somehow is possible to use this d21 gearbox. And do you have any knowlege about it? I see that the gearbox from d21 is shorter, but the front should fit well with SR20 gearbox bell housing. But how about rear end, or it's reallly just swap front section and put to sr20det housing? Thanks in advance for any advise :)
is it possible to swap the ka24 bell on to the sr20 bell for a sr20 transmission
Would a isr 240sx shifter work in a d22? It looks the same and you don’t have a bolt in the same spot I wouldn’t 🧐🧐
I've got a 1985 Nissan hardbody 3.0v6 5 speed I got 1st 3rd 5 the no 2 nd 4 th or reverse got any ideas thnkx
What is the part called that allows the short shifter to work called?
The selector bracket, as I called it, is actually called "Arm Control; Striking Rod" by Nissan, and the part number is: 32844-V5002
However, it is discontinued. Even the supersessions are discontinued. The best bet is just to source a blown s-chassis transmission being sold for parts.
@@Inner_Sanctum thank you! I was looking for selector bracket and was pulling my hair out trying to find it.
how mutch shorter is D21 trans Tail than 240sx ....and .....can you run D21 trans in 240sx ?....
what is manual shifter deal ??....
Great video bro. I’ve just picked up a ‘94 D21 Hardbody. Runs like a clock, but there’s a ton of play in the shifter. The inner silicone boot/dust cover is broken too. I’m struggling to find part names and numbers. I’m wondering if you’ve found an upgrade kit with maybe leather/leatherette boot covers for the 4 wheel drive and 5 speed shifters? Also do you have a reference for the names of the bushings or a manual with a breakdown technical diagram of the parts with the names and part numbers. Thanks in advance to anyone who can help. Cheers from the west coast of Canada! 🙏🏼🇨🇦⚓️
Wow, so doing this you didn't have to mess with the drive shaft right? I blew the trans in my truck and have an extra 240trs and was wondering if I could just rip them apart and swap parts over to keep the stock D21 case.
Yes you can do this without having to mess with the driveshaft.
This video is for people that want to drop an SR20 into their D21 without having to mess with the factory trans mounting or driveshaft.
You can swap some parts around between D21 and 240sx transmissions. The internals are almost identical except for the input/output shaft lengths and gear ratios. The D21 transmission and rear case are physically shorter than a 240sx trans and rear case; the internal shafts reflect that.
The transmission in this video is a D21 transmission and rear transmission case with an SR20DET bellhousing swapped to it.
You CANNOT swap the 240sx transmission into the D21 case. It will not work. All you can do is swap bellhousings and internal parts around.
The rear case has to match the transmission. The bellhousing is the only case part that is interchangeable.
Hope this helps.
nice!
Hi, I used a gear shifter off a RB20E gearbox for my short shifter, bolted straight on, didn’t need to change any
gearbox internals.
I have added a very quick video for to see it.
Nice work! Good to know there are other solutions out there that save some time.
RB20 transmissions are the same as the KA/SR/CA trannies
Bit of a long shot but do you by any chance have the part number for the sr20 gear shifter bracket that you swapped out, I'm in the process of doing a floor shift conversion on my td27 d21 using a ka24de gearbox however the box didn't come with the bracket that is required, I'm using a sr20 short shifter for the gear selector side of things so I believe I need the longer of the two brackets 🤔
By the way, absolutely love the channel and the build, so much valuable information on here, has really really helped a lot 🙂
@@johanneskloppers8937 Nissan calls the part an "arm striking rod" or "arm control striking rod". The Nissan general index code is: 32844M The specific Nissan part number is: 32844-V5002.
Hope this helps! 😎
@@Inner_Sanctum oh you absolutely legend! That is exactly what I was after. I really appreciate the help.
In case you're curious on the build too, I'm Currently running a holset he200wg on a na td27 with a compensated pump, a forward facing intake manifold from a forklift and a Ali express intercooler lol, in the process off swapping the ring and pinion from a z32 r200 diff too for better highway gear ratios 😄
Seriously I cannot emphasize how helpful your channel is to fell hardbody owners around the world haha. Big community of us here in nz and we all follow your channel for the knowledge you share!
@@johanneskloppers8937 that sounds like a really fun build. We were not fortunate enough to receive many Nissan or Toyota diesels over here. The ones we did get mainly live in warehouse forklifts.
I had a TD diesel in my Nissan Laurel Medalist that I imported, and it was rock solid. Loved that car.
I’m glad I could help. That’s the reason I make these videos. Hit me up if you have any other questions.
Cheers dude!
Ok so can you elaborate which parts are needed to swap in order to do the short shifter? I get the selector bracket part but is that it? I have a short shifter and was planning on just swapping it assuming it would works. Glad I watch your videos religiously lol.
To clarify:
This is only for SR/240sx KA short throw shifters with the integrated bases like the GKTech, B&M, ISR, and so on. You can install a different style short throw shifter on the D21 by using the simple lever style kit like the P2M or Megan Racing ones and toss all the rest of the bits in the trash. That's the way most people do it in their D21's. Most people just run the modified lever and that's it.
How I did it:
You will need to remove the tail section [rear case] of your transmission to get the old D21 [short] bracket out and new SR/240sx KA [long] bracket in. Unfortunately, that's the only way to remove and install the bracket. Even if you remove the shifter return springs and the two roll pins and try to spin the bracket out, it will hit the inner raised edge of the tail section. So after you have the tail section pulled back, you will be able to remove the two roll pins with punches. I put a rag under them and had a magnet rested to catch them when they fell. From there you can remove the old bracket and install the longer unit. Then reinstall the two roll pins. Hit the larger one in about a 1/4 of the way, then start installing the second smaller roll pin and drive them both flush. After that, I used the longer SR spring that goes in the hole to hold down the ball detent for the shifter return mechanism. Then I used some gray RTV and bolted the plate down finger tight, waited for partial cure, then torqued the shifter plate down.
Hope that helps!
Inner Sanctum clear as day. Thanks for that. I have the same style short shifter, and will, like you, be doing the KA D21 trans to keep the stock mounting location and stock driveshaft.
Can I buy aftermarket springs to put in after I do the bracket?
Is the D21 bell housing universal with S13 /s14 KA?
Yes. You can swap the bellhousing onto them.
Using redline trans fluid ?

@@Inner_Sanctum isn’ it gl4 only ?
@@Anthony_Torres209 people have been going back and forth between GL-4 and GL-5 for years because the FSM explicitly states GL-4 and there's the whole "brass synchro myth" about it.
Honestly, I just tell anyone to run whatever they are comfortable with. Gear oils today are WAY more advanced and can be used in a wide array of vehicles without issues.
There's nothing wrong with MT-90. Nothing wrong with running a standard GL-4 gear oil either. Honestly, it's preferential.
Short shifter nice!!. can you share how To find the short shifter
Yep, it's a GKTech short throw shifter for KA24/SR20. Just make sure you watch the video and understand what needs to be done to make it work.
Yeah for sure thank for you help man
How do you like the gktech short throw with the stiffer springs?
So, I have run B&M shifters for the better part of 10 years in all my S-Chassis and R-Chassis cars. I was a bit skeptical about the GKTech shifter. However, I installed one for my friend in his 240sx and it felt decent enough. It was time to buy another shifter, so I decided to get the GKTech shifter and springs since I had good luck with a few of their other products on my cars. Honestly, I can barely tell a difference between the GKTech and my beloved $300 B&M. They both have a similar throw, both have that notchy engagement with the smooth feel. Neither rattle, and dare I say... the GKTech is quieter. As far as the springs go, I'm running the medium spring configuration and it barely makes a difference. I tried multiple configurations to see if there's a difference, and it's negligible. If anything, it would probably make the shifter pop out of gear easier if your synchros are worn. Speaking from personal experience, the springs are just not worth spending money on. The caps look cool though. haha
@@Inner_Sanctum thanks man 👍, I think I'm just going to keep the stock shifter then. i dont really care for the notchy feel haha
@@NISMOntoya Word. It's definitely takes some getting used to.
I have a question I want to do this shifter in my truck and I already have the gktech short throw but having a problem finding the sr20 inner selector and the ball with spring
I can link the ball and spring later today when I get some time. The selector is a bit trickier to find outside of having an SR trans to spare.
Inner Sanctum another question do I need to do that if I’m not putting a sr trans like the way u did it ? I can’t just bolt up the short shifter in the stock D21 trans
@@smokey__9468 okay, so this video shows me using the D21 transmission [D21 transmission and D21 tail section] with the SR bellhousing only. So regardless of what bellhousing you are running, if you want to put the GKTech short shifter on the D21 KA transmission, you have to follow the steps shown in the video. You will still need to remove the cases to allow you to swap out the D21 KA [short] selector arm bracket for an SR or 240sx KA [long] selector arm bracket.
Inner Sanctum okay that’s the part I didn’t get let me see is some one local in San Antonio has a spare sr20 trans that they can part ways with
You can also skip all these steps, sell the GKTech shifter and buy an RB20E short throw shifter and it bolts up like factory.
