That was from Maddart when he built that car which I bought from him, he used hedmen block headers and built the pipe to the turbo flange. If you go to page 9 I believe on this section and look for the build thread you can see how he did it, my motor is being built srill so I can't really take pictures to show you how he did it.

But there are a lot of threads here for single turbo builds just go through them.
