http://www.tilbrook.com.au makes one hell of an intake manni. I am ordering mine from them for sure. The surge tank itself is a far superior design from the information I got from reading Mr. Corky Bell's book o turbo (aka the new testament)
Thought I would give you a different option than the GReddy or Uniques. They are a bunch of nice fellas, and do ship worldwide. Prices are pretty fair for everything else as well. A lot of the posts on skylinesdownunder.com seem to praise tilbrook's (aka sub-zero performance) work.
