Do you feel like it's something you needed? And can you still hear the BOV or the original compressor surge still? I really appreciate your help!

Hey,
Yeah I used Greddy's Flange. I went through Evasive, and this is the only one they carry. So I do believe this is the one I used:
GReddy Blow-off Flange Kit (Aluminum) - Type R, RZ, RS, S
Should still fit. All their BOV should be the same fitment with FV.

Hey! The Greddy FV you ran on your turbo kit, did u use Greddys universal flange? It doesn't say for FV and I was wondering does it still fit! Any help will be greatly appreciated!
