I have done this. And i had all the leaks sorted upto the intake. I then made a blanking plate for that and tested it! It was all ok!!
Maybe its the turbo? But i did change some bits. a 90degree bend for a hard bend. I am hopping those new joints are the issue. I have new connectors and clamps and will be fitting them tonight. I am waiting to hear back from Compressor racing about wither a rebuild kit or sending them my turbo core. Once thats done it should be about done.
I have a friend of a friend of a friend!! Who has a really cool bit of kit i am hopping to borrow. It connects to the charge system then presurises it but with smoky air! So you can see and hear the leeks. I am hopping to talk him in to letting me use it!!
