engine to put into my 1991 Eclipse GSX and in my car now it has turbo but the new engine doesn't. Is it possible to swith it from my old engine to my new engine without breaking anything or is a non-turbo engine supposed to stay that way? If it is o.k. for the engine, how difficult would it be to do?
