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, wiring, ecu, and maf.

 

Update 4-19-19 in all honesty if you can get an s13 setup its better than an s14. S14 head has a part in the cast that blocks the throttl cable. Its a pain in the ass but easy to fix.

 

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.

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

 

Konig209 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 with a 10" fan.

 

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."

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

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 #.)

get an egr delete kit. usually cheap.

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

Konig209 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

 

Konig209 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.

 

use the oem down pipe and have it routed however you like.

 

for the alt wiring unplug your voltage regulator and make 2 jumpers.

jump white to yellow and red/white to white black

Update

[flatcat19]

Good info to have around here.

[kelowg]

Napz (z series)trans mate up to ka's as well. 

[konig209]

Keogh the issue with that information is this.

Will the driveline work with that trans.

Does it mount the same with marks kit for the ka trans i dont know the answers. I know others trans work. But i dont know if theyre longer or shorter

[kelowg]

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. 

[]2eDeYe]

Excellent thread :)

[mrbigtanker]

I will say good write up.

[Draker]

Thanks for posting this!

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

 

They lean opposite directions.

[konig209]

This post needs to get pinned

[Charlie69]

Nice writeup Konig. 

 

How is the quality of the Black Market Innovations mount kit?

 

I wold say ask Redeye to pin it but you did not buy his mounts.  LOL 

[konig209]

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.

[mikec4193]

Hey Konig

 

Wow I am impressed...nothing like that even left in the junkyards to pick parts from around here...

 

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

 

Thanks for sharing on here...

[kelowg]

Sits the same as zx front to back wise(trans mount wise)

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.   :)

[datson4life]

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

 

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.

 

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

[datson4life]

Oh and i also vouch for blackmarkit's mounts, i call them better than oem

Heres his whole kit with his plug and play box

[mrbigtanker]

Looks good one day I will be as cool. That kick panel plate looks good. Does it mount first and then you lay your kick panel over.

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.

Wow...104 mph in a Datsun truck...that is stupid fast for sure...can I assume the suspension isn't all stock anymore is it??....

Ive maxed it out at 134mph. Um it has coilovers on all 4 corners, 4 link ball joint disk brakes and plenty more.
