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.*****

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."

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 #.)

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

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


i will update as needed.

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