im getting this combo along with some cobra 1.7 RRs, i was wondering would i be alright with egr passages and so i just need to use the studs from my stock intake, or would the stock TB and egr spacer bolt on....also can i port the stock TB and egr to 65mm?

 

Don't think they'd really port real well, there's the problem of the butterfly vavle, if you're not doing the whole thing it's probably not gonna be a big differance. You should be able to bolt your stock things back onto the new one. Don't think you need the studs.
