I've never worked on cars before, but I just picked up a 1993 Integra GS from my sister for $500. The car runs good, but since it was cheap my wife believes anything I do to it has to be an improvement, so she has given me free reign to do whatever I want to it. I have great ideas for the cosmetic stuff, but I don't know what to do under the hood. I think I might want to swap out the Automatic for a Manual transmission, and I was thinking about an engine swap. Any advice on what to do and how to do it would be greatly appreciated.
