D21 HARDBODY 4X4 Engine swap KA24DE-T

[Nismoskyline350GT]

I am taking my d21 4x4 and putting the ka24de
93 240sx motor in it I've modified the oil pan and pick
Up tube the motor mount are going to be tricky.
Any one done this swap Ive got pictures on everything I've done
Actually hasn't been very hard to do. The4x4 trainy bolts up
Just fine. .......

[seang]

The truck motor has 134hp/152tq, and the 240sx motor has 155hp/160tq**; but numbers don't always tell the whole story. Is your truck noticeably more powerful now? Does it have similar low-end output?

If the low-end output is just as good as the truck motor, then my thought is that Nissan purposely made the truck motor less powerful so it wouldn't step on the toes of the 240sx. I have always suspected that to be a factor in the design differences.

**Note that I compared a SOHC truck KA to a DOHC 240sx KA, but even the DOHC Frontier KA had 12hp less than the DOHC 240sx version, and I don't want to split hairs.

Well the truck is no together yet . I'm also biulding a hydrogen project
Out of the ka its a strong motor easy.to tuneand parts at easyto come up with
I also plan to turbo it . To give it some more kick

HERE IS MY NEW VALVE COVER ---- NICE----

Let me know how things go with the change-over. I've got a 91 with a KA24E that isn't running right. Was toying with either sending it out to be rebuilt, or swapping for the KA24DE! Not sure what I want to do yet. Found a good DE for $450, but.....
Interested in knowing how difficult the swap is before buying.

[Nismoskyline350GT]

This is what I've figured out is the ka24de should bolt up to 87 4x4
manual 5 speed transmission.

Since we all know that the Ka24 came from the truck anyways I wasn't surprised

So far parts needed
1. new oil pan fab.
2. motor mounts.
3. mod brackets holding trans to engine
4. ecu and harness for Ka24de of engine useing
5. fuel pump.
6 mod exhaust. turbo or non-turbo
7. mod power steering hoses and location of reservoir
8. starter for ka24de



parts used from truck on motor
1. flywheel for truck used on ka24de


wiring that will have to be done
1.


Stores and locations for parts
1.sheet metal 16gage any hardware store(oil pan mod)
2.metal tube from LOWES (sump tube)
3.90 JIC fitting mod accordingly to sump mount and tube
4.
5.
6.ebay: most of the hard parts turbo,fuel pump,
7.

i own a 1991 d21, 2wd... thinking about doing the de swap. will the ka24e computer and 91 d21 engine wiring harness hook up to the ka24de engine? my truck is a 5-spd.

[Nismoskyline350GT]

no, I would use the doner engine harness and ecu for the swap this will
make sure things run correctly.

[Nismoskyline350GT]

I went and got some 93 d21 truck doors that were fully complete black at the junk yard dirt cheap and like no rust

HERE IS THE START OF THE PROJECT FITTING THE ENGINE IN


inside floor pans rusted but not too bad, I am going to fix and bed-liner the inside


OLD DASH NEEDS WORK

HERE IS A ROUGH

I AM GOING TO BE FIBER-GLASSING THIS DASH FOR GAGE PODS


these seats came out of a 93 pathfinder and will work for the old trucks


The dash I am going to pull out and make a fiberglass mold


Here is the stock gauges


I am going to have BLACKCATGAGES work on making me some white facegages to look like this

IF ANY ONE IS INTERESTED IN ORDERING CUSTOM WHITE FACE GAUGES
E-MAIL ME [email protected] --- a group buy will help cut the cost down--- for the initial making of the gauge inserts

NEW NEWS -------- I FIGURED OUT HOW TO MAKE MY OWN WHITE FACE GAGES---- SO FOR NOW I WILL MAKE MY OWN

[Nismoskyline350GT]

power steering lines will have to be made

[Nismoskyline350GT]

clearance with the motor mounts and fitting issues

[Nismoskyline350GT]

[Nismoskyline350GT]

I took the z24e motor that I had in it and looked at the oil pan and took measurements. I then took the 91 ka24de oil pan and cut it like 1-1/2"
all the way around. I cut out pieces and then welded them together.

[Nismoskyline350GT]

HERE IS A COMPARASONE OF OIL PANS THE Z24E AND THE NEW MODDED OIL PAN I MADE TO FIT


custom rear sump oil pan for KA24dE I made

93 240sx oil pan


I HAD TO CUT THE REAR ENGINE TO transmission BRACKETS

[Nismoskyline350GT]

it is tilted on a angle in this next pic you will see this is for clearance of the pan with the crank and binging mounted ..... I have to weld a mount to the tube not done with the sump tube yet

the bottom of the tube is from the 87 z24 engine. I also had to use a 90 JIC fiting by the front which had to be fabbed for such tight clearances

[osegundo]

I'm liking this thread!! Goodluck on your swap!!

[Nismoskyline350GT]

As you can see on the oil pan I put in Return line plugs for a engine cooler
and the turbo return line




I am going to use a already put together turbo kit so I can save money on other things for this project

definitely want a good top mount turbo manifold

SEEING HOW THE TURBO WILL SIT ON THE ENGINE

I hate to bring this thread back to life but I am trying to do the same thing and I am running into oil pan clearance issues (even with sump reversed). I would love to know if the original poster had figured that out. Any updates? Has anyone seen a KA24DE in a 4x4 hardbody?
