CGA vs CG

[h701micra]

Ive heard a bit about the cg engine and the cga.
Not seen a thread on the differences. So just out of curiosity I thought I'd ask.
Aside from 1.3 and 1.4 what is actually different? And what is the same/interchangeable?

Hope I get this right :

CG / CGA crank is the same

CGA3 pistons are 1mm larger in diameter with different rods

CGA block water galleries are a slightly different shape (triangular?)

Ancillaries are cross compatable (flywheel, alternator, ware pump etc)

CGA3 pistons had thinner ring lands than the CG13 pistons

I think the cranks are different

The cranks are different, CG13 = 80.5mm - CGA3 = 82.8mm stroke. They share the same conrod too.

Now I have to tackle them again in more detail...
If I understand correctly, the CGa3 is the better CG13.
Manifold/ transmission and other CG13 engine-mounted parts are equal and thus fit plug'n'play
Is that correct?
At times to stay at the elbow,
so an original Nissan Cube Z10 manifold would fit in there because,same engine CG13

the CGA3 is coil-over-plug ignition stadik (and the post 2000 1.0) so there are many differences.
the exhaust mani,s fit the head ok tho

Okay,Manifold + exhaust plug'n'play...alright!
...but the rest is somewhat different.
When I read the specs so it hear that the cga3 is the better cg13

I thought the CGA flywheel had a crank position sensor and CG's didnt, so cant easily use the CG fly on the CGA. frank may be a better help on this one
