Was just wondering about using the engine from an impreza as a donor engine for other projects. Ive never really come across it happening but on a first impressions somewhat thinking out loud basis seems like a good idea. You can get imprezas nice and cheap as they are so common and their must be loads of crashed ones about you can get even cheaper and take the engine out of. Its a boxer engine so its small so wont be any worries about it fitting into what ever your intending on placing it into and it produces a lot of power. Its not hard to tune it more if you want or even detune by loosing the turbo. I guess their is the noise as well but thats a love or hate affair and not necessarily an appropriate noise for your car to make depending on where the engine will end up in. I was wondering if the problem lied somewhere with it being 4wd meaning getting a gearbox sorted for it or running it just as RWD is hard so hence why it isn't used in other projects?
