remove TMIC..?
 

Un-done bolts 1,2 and 3. Loosened the pipe (4) around the throttle. What else? Is there a pipe to remove underneath? Is number 5 the dump-valve? Will this have to be removed?

There's the turbo to intercooler hose - have you disconnected that? (at the turbo end)
Least thats what I had to do on an MY01

probably that then...

The hose from the turbo can be a bitch to get off, but it will come free, just be patient and do lots of wiggling :)

Number 5 is the dump valve, the pipe (on the intercooler side) that it connects to also goes to the turbo, you need to loosen the big jubliee clip there.
