Hi guys...I've got a few days off so I have a little time to do some research on building a countach/(other kitcar?)

I saw some things about a countach kitcar (the body was made from scratch...it wasn't a kit) that was based on a Volkswagen Beetle. I now know how to build the body, and lowering the car and stuff won't be a problem...but what I'm a little worried about is the engine. It's in the rear (behind the rear wheels), so does it fit in the body?
If any of you has any info about changing a beetle in a countach, it would be greatly appreciated!!

(reason why I want to use one instead of a fiero is because:
1. they are CHEAPER
2. parts are much easier to find
3. easier to work on
4. lighter
5. wheelbase almost the same as countach's)
