h22a swap

Hi, I was wondering how big of a job it is to swap an h22a into a del sol? Some one told me that doing to do the swap i have to tilt the engine back a little when it is usually tilted foreward and that causes the car to have a lot of over steer or somthing like that. Is he full of it or is it true and if it is true is there a way you can fix that?
