1.3 and 1.5 Festivas (Aspires)

[BrianFestiva]

Hey guys got a few questions to throw at yas!
First off I have 2 WB Festivas (Aspires) both manual 1 is 5 door the other is a trio.
1: How do you check what size engine you have?
2: Are the heads from a 1.3 and 1.5 comptable?
3: If they are does anyone know if it would be good to put a 1.5 head and injection system on a 1.3? Would it make it better? Would I have to change the computer?

Thanx guys!

I believe, these questions have been answered before. As I recall, the heads are NOT interchangeable. Basically, any engine changes would require the right computer. Do a search "engine ID" for info about id of engines.
