I have a guy on thepartstrader.com selling a greddy tdo5-16g turbo and manifold. He says the manifold was custom made by the performance factory in nyc...Also what should i offer him?? he says the turbo was 750 new and the manifold was 650...theyre both about a year old...it seems like this setup would be a really good starting point for a turbo assuming that the parts are good and stuff..is there anyway i can check the legitimacy of the parts and things? possibly call the performance factory and ask? im just a little weary since my friend nearly got ripped off from a guy in cali selling him a greddy turbo kit for his integ...anyway let me know soon i leave for cancun tommorow for a week!!!!
