Geo...

I have a 1995 Geo that I want to either do one of two things to.
One put a bigger engine in it, which I have no clue as how much that would cost and how they would do it. Two, second choice just build the hell out of the stock 1.6 liter motor. I want to put total about 3grand in the engine and about 3grand on cosmetics. I need to know if I can put like an 03 Cadillac engine in it and where I would take it to do something like that and if that’s a bad road to take what I should do to the stock engine. Help with any information thanks!

You can put the Caddie engine in, but only if you live in a trailer.

With $6k on hand, why not just buy a different car? If you just really want to modify the Geo, you might want to consider skipping the amateur stuff and get a jet engine and crush the jet bug (http://www.blogcdn.com/japanese.engadget.com/media/2006/03/VW_Rear_Dr_Open1_PScopy.jpg)

Try a silver or blacktop. Atleast those engines are almost a direct bolt in.
