Parts commonality - Starion & other cars

[Paradoxx]

The aerial in the pillar is replaceable with a magna one... identical fitting although it is a little tight towards the bottom when pushing it all the way in.

Cordia diffs swap straight in

Can this be true?

Are ratio changes due to the interchangeability of this part
possible?

I got a Cylinder head out of a 2.0 N/A spacewagon and it was a easy swap for my cracked cylinder head
Just the combustion chambers are a bit different. but it runs fine.

That makes two of us who have a head of a spacevagon but dose´nt it have smaller combustion chambers = Higer compression = some exta power

I'm not su sure the combustion chambers are smaller.. I tought the same but when i put it down i tested how much water each bowl would hold

it was the same as the original head.
The Spacewagon head just has a rounded combustion chamber (no edges)
and some king of dent in it opposite of the sparkplug opening..
