I recall reading an article stating that Subaru was making a hybrid engine that would be able to placed in even their older model cars. I also seem to remember hearing that you could possibly do it with hondas. Ive looked around for information on honda hybrid engines for older year civics but I havent found any great resources. I need a cheap alternative to buying a new car and I like a good project. I think if people could do an engine swap in their older year vehicles than perhaps hybrid engines would see a higher demand, not everybody that wants to help the enviroment and save money can afford a 20,000 dollar car. What do you guys know about this? any good resources or even buying options?
