Thoughts on this LS1 Turbo kit
 

You get what you pay for.

Very true. Also, that does not come with the turbo, you are just getting the hardware to build a turbo kit.

I posted that on LS1tech today, they said it can be done but a pain in the ass to work with

lot of people on ls1tech have been using that kit with mixed results, yes you would have to piece together all the missing parts, and best idea to either get the hot side powdercoated or wrapped.

theres always the issue though, if the piping is stainless steel and the flanges are mild steel, then you have the issue with cracking due to the two metals that heat and cool at different temperatures.

Doesn't look like all that bad of a kit....coat it, wrap it, and send it!
