I am selling this kit because I have several different turbo kits from japan. I don't plan to use it so I put it up for sale. I have test fitted it on my z and it fits, but I think fabricating the down pipe will be the greatest task. Remeber several styles of these kits were manufactured in Japan, yes this is an orginal. Some will not fit, due to the lenght of the runners or other reasons, however this one can. I have several books that provide information about these kits, so knowledge in hand is better than speculating. Well, I hope this will clear up the rumor. Thanks Guys
