You left the neo cover on. There's your problem, removing the cover clears up a heap of space, should allow you to push the piping more into the silicon joiner and then allow you to bring it back a bit from the fans. Either that or a crap fmic kit. Or both.
I've got a GReddy M-Spec FMIC on my neo. I was told by some idiotic part providers that it wouldn't fit on a 25neo, only standard 25.
Sits about 3cm away from the fan, then clamped it to part of the engine so it doesn't budge at all. No fan cutting required. Hard to explain where it's clamped, meaning I dont know what part it's near lol, post a pic when I get home.
