Figured this was a better place then the FI section while the car is beinmg boosted I do need some help getting this intake mani set up.


1:IACV I have no idea where or how this even can connect to the I/M
2:water outlets I circled them the stock has 2 my S2 doesn't have anything just a 1 hole.

If you have one it would be a huge help if you could posta pic of how you have the IACV hocked up and what you did with the water outlets.

Car is a 98 integra with a 98+ JDM b18CR in it.

 

i believe the s2 has one big one.. but with a fitting perpendicular to it for that smaller one
so the flange itself has one hole

although thats odd as the s2 ive seen are universal for gsr and b16a so it has more than one hole

why not post an actual picture of ur s2 ultra street IM ?

 

Maybe this helps: https://honda-tech.com/all-motor-nat...es-im-3157724/

Easiest way is just delete valvecover vent/ throttlebody/ IACV heating circuit (because of flipped tb and relocated IACV). With EK4's water outlets, I routed hose from behind waterpump outlet pipe, straight to the cylinderhead. EK4's stock intake manifold don't have that smaller water outlet either, it is in cylinderheads radiator outlet.

 

Thank you very much!, I missed the bag of fittings for the water outlets, ya just going to block the lower one. I see you just have to use a nut/bolt combo to holt the IACV down. Thanks again man I tried typing in S2 ultra street install nothing came up with what I was looking for. Going to ditch the PCV system anyways.
