Build a 4" intake. For about $150 you can buy a silicone 90*, 45*, some 4" aluminum tube and new air filter. Then you have no worries of restriction. Since you are SD you can leave the MAF out if you haven't already to get a full 4" up to the throttle.

One way of building the intake would be to use some 4" aluminum 90s and straight silicone couplings. The Al. 90s are $35 each so it will work out a little cheaper than using silicone bends. You can cut 45s or whatever you need out of the 90s. If you have access to a tig welder you can weld the whole thing up.

IMO you don't want to go any smaller that your TB opening... So I would keep it at 85mm or larger... BTW I have a 2ft section of 4in Aluminum intake piping you can have for free if you pay the shipping (~$10). I accidently ordered it instead of steel and I don't need it cause I can't weld Aluminum....
