Dave they are the S400Sx's. He will know the complete line just off that naming system. Direct part # is 177101 for that particular unit. We keep them in stock with our Turbodiesels.net shop.
They are an awesome piece indeed. Very nice stuff, and they also make a 60psi and 120psi model as well. Though I doubt anyone here will need that much boost. :D
Turbosmart East is a stocking wholesaler. Also turbosmartonline.com as well.
Sick pictures.....that 98X is working well for him. He's making over 1000rwhp at only 20psi and a small 366 LS1 motor. It will be fun to watch when he's in the 30psi range.
Do you have the tag off the turbo. The TV7101 had multiple models. Ranging from the 4XXXXXX-0001 all the way up to 002X. I can narrow it down for you exactly if you have the #'s.
Yeah our BW turbos are just a blip on the map compared to the amount of Garrett's and Turbonetics we sell, but they are inching closer. We sell a ton of them to the diesel hot-rodders though.
