i have put on skunk2 manifold for the gsr and the b16 before.
and a friend wanted help putting on a skunk2 intake manifold onto a 92 integra
and the oem once has a bunch of lil vaccums around it and i dont think it will go
onto the aftermarket one.
the intake manifold is skunk2 pro series and its trying to go on 92 integra LS B18A

 

i ran a blox mani which is replicated from that skunk 2 and i know which vaccum lines your refuring to. honestly i dont remember exactly what had to be done if much at all becuz im pretty sure once you pull that old mani you will be able to delete most of those lines, if not all the extra lines. I had a full wire tuck in my old DA an was very... **** if you will lmao. but Im not the kind to just stick screws an **** in vaccum lines that no longer have purpose na mean.
soo if i were you Id just start the upgrade an with a vaccum line diagram you should honestly be just fine.

 

you could follow the vacuum diagram thats under the hood
