datman55,
How has that system been working for you? I see that you installed it in 2004 to early 05. Does the production pump work out ok?
I am considering a similar system on my SR20DE.
What type of restrictor are you required to run. In the States we have some cars restricted by a single inlet restrictor similar to the FIA GT style restrictors.
Edit: I did some more looking at your pctures and I see that you have to affix the 36mm restrictor to the front of the Turbo inlet. Sorry for that. But at least you get to run a Turbo.

Cheers
