Hello,
I'll make my presentation first.
Im Alex from portugal, and i have a 1200 4 door deluxe from 1974. I'm starting to think about a "new" engine to my baby.
I think (and correct me if i'm wrong) that i can put an A14 or A15 from Datsun/Nissan sunny (along whit gearbox, brakes, etc) straight in. Am I correct??

These later engines are a good choice, but from about 1974 [B210 model] they moved a few things about .
The altenator was moved from down low on the left, to up high on the right. To make room for it, the distributor was moved back to be near No.3 cylinder. To make this all work, the fuel pump was pushed back, & to make room, the right side engine mount was also moved back a little.
The left side was not touched.

To fit the later engine, you can either
A....Use a front crossmember from a 74 & later ute. [B120] These used the later type of engine, so the finished job would look "factory", or.....
B.... modify the right side mounting tower to pick up the new right side engine mount insulator [the rubber bit]

You will also need to modify the wiring to pick up the new altenator position.

It might be an idea to switch the thermostat housing from your original engine if the A15 one is not pointing in the right direction.
It's not a hard job, but it is a rewarding one.

My Datsun is from january 1974, i read that the 1200 from middle 73 and 74 had the changes.
I can put a picture os the engine bay to see if i can pop the other engine right in or if i need to make those little changes.

Thanks for your reply

I know the picture isn't too good but it's the only i got at the moment.

If the distributor is at the front, with the altenator on the left, then it is the early engine.

If the distributor is near No.3 cylinder & the altenator is on the right, then you have the later type engine. If you have this engine, then the A14/15 will fit right in.

Left & right is always taken to be as if you were in the drivers seat.

well in my experiance of putting in a newer A series in place of the old one in my 74 120Y all i needed to do was change the intake side engine mount, and it bolted up fine. all wiring reached and was not tight and everything went on okay. i put in an A14 and had no troubles i did the conversion in a day. that included putting on the booster and other items from a late 120Y. you make things a lot harder than they seem most of the time dodgeman i like your ways of looking at all things that could go wrong but you can scare people away from doing things with your exasperating indepth views. no need to make things harder than they are.....

Yep, no modification are needed to the body or crossmember.

Use a simple flat plate to adapt the motor mounts on one side, and a simple flat plate to bolt the newer transmission mount to the body.

Im starting to look for a donor.
L8r im thinking about a c18det conversion, that will be a little more difficult but i'm couting with your help to make it happen. And then i'll have the fastest and most furious 1200 in portugal

Kidding but probably is true

I remembered now, got just one more question to make.

What figures can i expect from the a14 and the a15 engine mounted on my 1200 ???

0-100 km/h @?? secs
Top speed
Hp
Nm
Etc

Thanks in advance

Top Speed: no change, as you'll hit the redline at the same speed. If you change gear ratios (or use overdrive), you can probably go a bit faster.

0-100 km/h @?? secs
This is about 21 secs with an A12, so I would guess 16 secs with a stock A14 (just a wild guess).

21 secs'???
I haven't measured yet but it certainly isn
