My A12A is imported from Japan and it has oval ports head with manifolds similar to early 80

Yep, heads are aluminum. The A-engine is a very reliable engine, and might not even leak any oil ...

I am thinking about boring and using A14 pistons. The color of the engine block is blue and the head was silver in the picture. Do they paint the heads silver ? I'm use to British cars where they paint the engine and head the same color. Are Datsun heads alumunum(sp?)

I'm using this engine in a Lotus 7a replica (locost 7) that I'm making from scratch. I wanted to use a better engine than the MG Midget 1275 I was going to use.. On of the guys from down under said the 1275 was Pommy! So I don't want to use a Pommy engine in my replica!

and again I really thank you for all the help you have given me.

OK, with distributor under #3 cylinder and mark "A12" it is either an imported used non-US 1974-up A12, or it might be an A12A. But b310gx says the engine he saw was definitely marked A12A. So assume it's an non-US A12.

In either case you will need to modify the motor mounts to put this engine in your Datsun 1200.

I wouldn't worry whether it's A12 or A12A about this unless you are talking about racing or boring the cylinders.

Ok I just looked at the pictures in the best engine section and now see the valve cover orientation, the distributor is right under the #3 cylinder

I just received pictures, the distributor hole ( there is no distributor) seems to be right under #2, unless I'm confusing my front and back. Could I send (post?) the pictures to you, I'd like your opinion on it before I put the $$ up. It looks like a new engine!

The A12A is a larger displacement engine (about 60cc) and apparently the cylinder thickness is different. But the biggest difference is that the A12A does not bolt-in to a Datsun 1200 without some minor motor mount mods. It is more like an A14 than an A12. The US version has the small round-port head with low compression.

Note also that the A12 was never available in US model B210s.

See Datsun A12A engine and What's the best engine to put into a 1200?.

Quote:

There is no displacment changes between the A12 and A12A the last two numbers are the displacement eg A10 - 1litre / A12 - 1.2litre / A13 - 1.3lt etc etc.

A12A has higher compression due too differnt head the short block is exactly the same altough differnt dizzy location.

The Head has double valve springs.. tell her to take the rocker cover off to verify thats what i would do.

The salvage yard is e-mailing me pictures.
Unless the yard women read it wrong, the engine could have been marked from a B-210 (USA Spec) and is an A12.

Are there any other changes besides displacement on A12 vs. A12as?

thanks again for all the help on my uneducated questions.
