What is the cubic inch size of the engine?

Answer

Probably 1.3 Liter.

in cubic inches would be between 70 and 100. I'm sorry,i don't know the exact number.

1.3 liter festiva engine is 81 CID

the e250 if a straight six is a 300ci 4.9 litre

Multiply the cc's times .06 . This is not exact, but it is really close. For example: 1450 cc's will show 87 c.i. When it is actually an 88 cubic inch.
