take a looksky at that, and tell me what you think...? i was kinda confused on the logic but idk, makes me want to get a MBC if thats the case....

 

dont get the ebay ones they may be 13$ but they are garbage.. get a good one from Forge or TurboXS if you do get one

 

if you are staying with a stock or small turbo with no real lag, you will also want a bleed style mbc. Ball and springs like in the link cause major spikes and make DD a little harsh. Your only alternative is adding 40 vac connections like in that link and its just a cluster &*#_ where a bleed or combo bleed and B&S will work smoothly w/o the n75
