hey guys i was planning on installing the hahn intake manifold but i dont have an instruction guide as to where and how all the hoses connect. can anyone share their wisdom and help me out on this.
i can figure out the taking off parts of the actual old manifold and bolting on the new just need the rest
thanks

Try contacting Hahn for information. Sorry, not much help here. What part of Dallas do you live. Got to see that car.

if yuu live closer i woudl of helped you out

thanks. ya im kinda in an area where there arent any cobalts. mostly just civics and integras

well i would have so see the manifold to be of any help, and i need to know the lines you have to connect, most of the lines are vacuum lines, one for boost gauge, one for wastegate actuator, and the others woudl be brake booster, and the other little plastic line

ah ok. i didnt know about the wastegate one or boost gauge. i see in the pics that it looks like the air flow sensor is on the far left. the brake booster in the middle and another senor of some kind on the right

it's easy
large middle hole, brake booster
passenger side - mount the MAP sensor
Driver side mount the scip sensor
and you need to run the PCV off the head flange on the new manifolds with a check valve, can be tee'd off where the brake booster line is, or run a adapter out of one of the 1.8 tappings, use the other for the BOV

ya the pic of it is in the appearance forum under show off your engine bay. page 13

thank you sooooo much for the info.

do u have pics of the manifold on here? because the ones i saw are kinda far away.

can i see the front of it, but i need to see the lines u want to connect...
so far the ones i know you need, dont know if they are done yet are

wastegate actuator(this oen can be fromt he charge piping or from the manifold, depends where u want it to read from)
boost gauge(can be T'd into the wastegate one, althought to be more accurate reading from a nipple on the manifold woudl be better)
brake booster line
BOV line(has to be from mani and can be T'd with the boost gauge)

those are the one i know you will need

i can draw up a diagram to follow but i need to know how many nipples you have to pick from, and where you want to read ur boost from, you can do

(a) wastegate read from manifold, thus you get thru boost cut at the wastegate set psi
(b) wastegate can read from chargepiping, thus cuts boost at set psi at that point of the piping, and you will experience pressure loss as the boost goes thru the piping and thru the IC, and bak into the manifold, so whle it cuts off at say 8psi, after soem pressure loss maybe onlly 7 make it inside the engine

(a) boost gauge, read it from the charge piping, in which it will rear the boost at that point
(b) read it from the manifold in which it will read the boost that actually made it inside the engine

reading from manifold is always best for the most bost, but might cause boost spike
