<![CDATA[MPFI swap questions]]>Hey, so im doing this MPFI swap on my 90 civic hatch (dx w/ a d16a6) and I have some questions.

Actually if someone could come over and help me with this sometime this week GODDAMN that would be awesome! I can't promise to pay you or anything but some beers or something would be in order.

picture 1 and 2: I have these three hoses left which I think are for coolant. On the DPFI setup there was a tubing that looked like the second picture but it only had hoses connected to the small line and the big line wasnt connected to anything and was cut on the end. Where do these go, or can I tee these?

picture 3: This is how I have the hoses set up, I color coded them for clarity. Is this correct? The hose that I marked shows in the manual that it goes down back behind the manifold, but to where?

picture 4: lastly there is a nipple on the egr valve that I dont have a hose for. I also dont have a harness for the egr valve, am I supposed to?

I know this is probably newb honda stuff but I tried to be helpful with the pictures.

Any help is appreciated.

So i ditched that for a proper Si setup and everything went on like buttah. Im waiting for the washers and seals and shit for the fuel rail and then I'mma fire this bad boy up.

I'll give a call over there though. In the meantime, anyone else want to give me a hand?

edit: the EGR valve and fast idle thermal valve are both getting blocked off. fuck em. still need the rest of the lines checked tho.

If it does, I don't have one, it's not on the back or the intake runner where it should be. Do I even need that? Can I cap it off somehow? It's like $150 at the dealer.

I know someone here totally wants to come over and help me. I live in amber valley, one of you dudes that lives around here has to be a honda lover.
