well to start of you need a 521 1969.5-1972. that came with the l series for this write up to help you out.
if you have a j series.....ehhhhh you're shit outta luck but this may still help.

second you'll need a 1991-1998 nissan 240sx ka24de engine set mated to a 240sx 5 speed transmission.

no the frontier ka24de engine will not work as easily. it is a rear sump oil pan and it is not interchangeable with the 240sx pan and pickup tube.

no i don't know if any other trans will work with the info im giving.

no you don't need to cut into the trans tunnel for it to fit.

no there is no fabricating to make it fit.

yes it will drop in with the trans mated to the engine but you will need to remove the crank pulley, alt and water pump.

to avoid any hassle sitting the transmission in its place undo your torsion bolts as far back as you can then set back in after your done.

so parts list.

ka24de 240sx motor set

engine bracket kit from blackmarkit; http://www.blackmarkitinnovations.com/
oem 521 engine mounts will be reused.

TIP!!! when dropping in bolt the motor mounts to the engine gives another inch of
clearance when setting in place then carefully bolt it into its place.

to fit oem radiator you need upper hose part #d71236

38867071571_ff5e3f0fb2.jpgKonig209 521 KA24DE Swap 012 by Carlos Ortiz, on Flickr

lower hose is oem.


I recommend a aluminum radiator upgrade to help with cooling. ebay ones work great.
521 shares radiators with the 510 to make it easier.

also recommend an aftermarket temp gauge. "i don't trust oem temp gauge never have."
buy a autometer temp gauge and a mishimoto water temp adapter part # mmwhs-38-bk ******don't forget to ground it.*****

38836875672_7723d467df.jpgKonig209 521 KA24DE Swap 008 by Carlos Ortiz, on Flickr


you can go my way and get a custom radiator built 24.5" wide 16" tall 3 row cross flow design
with both hose in and out on the passenger side and use the stock 240sx hoses to fit.

a custom 1 piece driveshaft needs to be measured to fit your truck. average is about 51" inches.
"some trucks depending on height or suspension setup will affect this."


38837472592_ccfff483c2_b.jpg2017-12-06_12-17-16 by Carlos Ortiz, on Flickr

wiring; icehouse member on here makes a great product to make it a almost plug and play setup with his canam box. comes with full how to tie it in to the harness.

SECOND METHOD OF WIRING
Custom wiring done by
"J's wire technologies"
Located in modesto ca.

$300 for regular loom
$350 for higher grade mesh loom. Looks much nicer like pictured.

buy 1 or 2 12" fans and place them where you like. pull push your choice.

24002187237_290c177a13_z.jpgKonig209 521 KA24DE Swap 011 by Carlos Ortiz, on Flickr


to do a single belt setup.
use a single cam ka water pump pulley, alt bracket, thermostat water neck housing, (and belt to fit will update later with part #.)

24002186407_4ce67f959b_b.jpgKonig209 521 KA24DE Swap 014 by Carlos Ortiz, on Flickr

for the intake you'll need 2 3" 90 degree elbows from autozone

37980507775_d923ce2150.jpgKonig209 521 KA24DE Swap 018 by Carlos Ortiz, on Flickr


2 pieces of 3" piping for the intake and a filter of your choice.
don't forget to connect the hose from the throttle body to the intake or it wont idle

38836873632_abcece1593_b.jpgKonig209 521 KA24DE Swap 020 by Carlos Ortiz, on Flickr

remove all but 1 vacuum to the fuel pressure regulator.

use a walboro 255 in line fuel pump it works or a 280zx fuel pump works to "i think"

water routing will be your deal i ran almost none no heater nothing so i got no tips.

there is an orange wire that ties into the starter signal.....dont forget to wire it in lol.

for exhaust you can use the stock manifold you can get a manifold flange collector made by erich paul
at japan automotive engineering and take it to put on at a shop to be routed around the e-bake and torsion bars

38836873022_d1af16a16a_b.jpgKonig209 521 KA24DE Swap 021 by Carlos Ortiz, on Flickr



for the alt wiring unplug your voltage regulator and make 2 jumpers.
jump white to yellow and red/white to white black

http://community.rat...ur-drive/page-4

i will update as needed.

now do it and go roast some tires!!!!

Z trans sits same as zx trans and u do have to put trans in place before motor. driveline should b measured and made to each truck. cause there r slight differences from truck to truck.

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.

You're going to skin a few knuckles, stand up too fast and bump your head, hunt around the floor for the nuts and bolts you dropped, invent a few new cuss words and when you're finished you'll say "That wasn't so hard after all!"

Z series/KA transmissions do not sit the same as a ZX/L series trans.

They lean opposite directions.

Dont even know who redeye is nor that he made a kit. Mark is local to me and in all honesty if i had the money to afford his time and labor i would have him build my truck for me. His work is simply amazing. So far not a miss with his kits.

So how quick will this truck be when it is all said and done??

 

Thanks for sharing on here...

Me lol.

 

My 521 kits are just finished, wasn't able to get a test subject until recently. Still need to order plates for my first production run and develop a transmission mount for the longer 240sx trans.   :)

Nice writeup,
Would like to add that the 38 mm sensor adapter from mishimoto is a very tight fit, but it works, but 36 mm would be better, heres how it looks installed
20161216_083854_zpshqcf1psf.jpg

Also, these ears lay right in between the torsion bar bolts, CUT THEM OFF, they are useless and are the only things u will put up a fight with when installing trans, unless u remove torsion bolts and put back after trasnmission is installed, but either way its a bit of a tight fit and life is better without those tranny ears.
20161216_083827_zps2oyhoxpy.jpg

It should also be added the cost, all the little stuff really add up. I can make a price list later

Well my truck has been taken down to 2040lbs with me in there. Its fast. Ive left astovk evo 8 behind diesel trucks. Few v8s. I was toying with a new camaro ss the other day. Kept side to side with him up to the top of 4th about 104mph. Hit 5th and was left it lacks the umpff after that but i am impressed on how fast it is.
