Hello everyone I am new here and just thought I would chime in. I bought one of these kits about 2 months ago. I have not installed it yet as I am still waiting on my transmission and a couple other items. I will say this I had the same reservations about buying a cheap (EBAY) kit. I did some research and said the heck with it and I ordered it. I have always ran superchargers and wanted to try a turbo and this would allow me to do so without loosing a load of money if I wasn't thrilled with the way it performed. When the kit arrived I opened everything up inspected it and was blown away. The kit is a hell of a lot more than I expected. It does not appear cheap in any way and is very complete all the way down to the nuts and bolts. If it all works as good as it looks then I would say the kit is worth every penny. I will know soon enough as I expect to have the car finished in January. For the record it is an 87 to 93 kit.
How do the welds look? Could you take a few pictures of the welds on the inside and outside of the pipe maybe near one of the ends and post them before you install? I haven't seen one of these kits up close yet, but my past experience with stuff welded in China is that its typically welded with an incorrect heat range, its not back purged, and they pulse weld over the bad welds to give it a nice stacked dime appearance.
