bullshit you say contributed to the fourm shutting down once already? Are you just that immature and don't have a life that you need to contradict everything that is questionable? Just keep your chilidish remarks to yourself. Who are you to know that the the materials in the later engines were not better. Just because you own a 90, you don't need to be sore about the subject. Are you a Nissan Engineer? Just shut up. Z Whore.
