Ah, jay is right about the intakes without a 90 degree in it already. Ones that come to mind are the bomz and aem cai, and the mac shorty intake. I totally forgot the aem and bomz don't have the bend.
Ok, I just tried it with a 2.5" silicone coupler I have from my turbo parts and it fit on the stock tb with a t-bolt clamp. Just makes it. To go from a standard intake like the iceman with a bend already in it all you need is a 2.5-3" straight reducer, I bought one from extrememotorsports.com for 18+shipping. They also have the bend for $45 (cheapest I could find after a quick search)which is alot but if you get a bomz and the bend it comes to about $100 total for the cai and the bend which ain't bad if you can't afford to get a tb too at this time. The bomz and aem cai have 2.5" piping so all you would need is a 2.5' 90 degree bend.
I would contact lance at jgs precision turbo first to see how much he can get those silicone bends for. They are not on his site but I belive he can get that stuff too.
if he don't have it then these guys have some good prices.
