I have been working on this for a while now with the help of Jonah and his dad. They had a 521 and a KA24DE that needed a home. 

 

We started out trying to fit it with a 240sx transmission, but we found that you would have to cut the floor and maybe the torsion bar adjusting bolts to get it to fit. Thankfully they also happened to have  a 720 transmission and that makes it a complete bolt in affair.  

 

I still need to work up the rear mount as it will also need to be fabricated but I thought I would share the progress now that we are seeing results. :)

Hood closed, hood is pretty beat though so it would be nice to check with a good hood.

Where the custom mount needs to be located in the rear.

Will be working up the rear mount this week if I get time. :)

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!"

This might be a dumb question, but is that a 240sx front sump or D22 rear sump KADE?

 

I've never messed with anything older than 720, so I have no idea if the older trucks are front sump from the factory.

 

 

Must add, that is some great work on the mounts and fit up.

It's a 240sx front sump motor.

 

The 521 is much better suited to this swap than the 620. The 620 is a very tight fit in the engine bay.  

 

Thanks, it's taking a bit of time to get things done without having a truck to do the swap at my house. Jonah and his dad have been super helpful though. :)

Interesting.

This might not need to be asked, bit the I go will be here...works for KA-E also, right?


Also...was that a 31" or 26" 720 trans?

Yes, will work with the E both 240sx and truck versions.

31" transmission is being used.

26" mount can be designed, I can get measurements for the shorter trans next time I'm at their shop.

Looking at the pictures, it looks like the 26" would fall almost dead nuts in the factory position. Not that it would have a speedometer pinion, which sucks.

Very nice work Redeye.

It would probably fit really well in the truck. I'll get measurements so I can offer it as an option. :)

Long bed 720s have 31" trans.
2wd trannies have speedo in tail housing.

That 2wd tail housing can be swapped on to the 4wd trans.

How different are the two mounts you made from each other? 620, 521.

The 620 mounts are 3/4" shorter vertically than the 240sx mounts. 

 

The 521 mounts are 3/8" taller vertically than the 240sx mounts.

 

I'll get a side by side picture tonight. 

 

 

 

Both of my mount sets use 620 L20B isolators. 

 

 

Another thing I hope to be working on soon is SR mounts for both trucks. I have someone sending me stock SR mounts and willing to test fit them in his 521. :)

If the sr is a Direct swap in a 240sx with its mounts it would kinda seem like it wouldn't be very different. but idk.
Awesome stuffs!

Everything I've heard says it is a direct swap. The only difference between the two is the block side pattern and location. Hopefully it all works out easily enough. :)

Will be working up the rear mount this week if I get time. :)

521%20Transmission%20Mount%20Bracket%20M

 

The mount I have pictured is the early 521 transmission rubber mount and the cross member mounting bracket.  Be sure to use all 4 transmission mount  bracket mounting holes on the cross member.

 

I would change the transmission mount to the newer type and build the rear mount to fit.  This is Anchor Part # 2742 or DEA Part# A2742

 

The reason I suggest this mount is it will fit 4 speeds, 5 speeds and automatics.

 

Fits this range of trucks.

NISSAN 521 PICKUP        1972

NISSAN 620 PICKUP        1972-1979

NISSAN 720 PICKUP        1980-1986

 

The Anchor and DEA mounts are from 72 to 86.  I know the 620 used this mount but have not seen it used stock on a 521

Yep, the plan is to use the factory 521 cross member mount configuration along with a 620 transmission mount.

I'll post some captures of where I am in the design process after work.

Transmission mount for the 31" transmission and a 620 isolator is looking something like this.
