I'm in the process of removing the "rats nest" and want to know exactly what needs to be done. If anyone has a picture of there motor minus the upper intake that would be great. Thanx

Chris

 

You have the twin scroll still?

 

i don't have a picture but i did this on my TII. basically you unbolt the whole thing. your gonna need to cap the vacuum lines on the throttle body and get some extra fuel line to run from the hard lines to the fuel rails, i also removed my charcoal canister and capped the hard line going to the tank. i don't have a pic of it on my car but its VERY straight forward. you should only have about 4 vacuum lines when your done

 

Nope Felix I got rid of it. Alright vosko thanx, I already took the nest out, but don't know where to start in getting it back together, what about the line that runs to the oil fill and what about all the fuel lines, I'm gonna go try and get a picture and then ask from the pictures.

Chris

 

Buy some fuel injection fuel line and run it from the hard lines to the fuel rails. Get some vacuum caps and cap off any exposed fittings. Hook the fuel pressure regulator to a nipple that gets vacuum and boost. Leave the oil fill line on the bottom open (put a breather filter on it if you so desire), and cap the one on top. I have a picture, but its incredibly crappy.

 

you basically CAP everything. i went to pep boys and bought a vacuum cap kit with various sizes. the only thing is when you start the car now when cold your gonna have to hold the gas a little then it will idle on its own

 

Alright thanx, I just took some pictures, working on getting them uploaded, the cold start is no big deal, could you go ahead and post the picture anyways Felix thatd be cool.

Chris

 

i should have taken pictures when i did that. oh well i was too damn lazy

 

Number 1

 

Number 2

 

Number 3

 

i have no clue WTF pic one is. i don't have that on my 89 LIM. pic two is your secondary fuel rail. like felix said just run that vacuum hose to a boost/vacuum source

 

Number 4

 

Number 5

 

Number 6

 

1 is the cold start ****.
2 is the FPR
3 is the primary fuel rail. Feed it the line from the fuel filter.

 

Alright pic one is something to do with OMP i think, not sure though, thats why I'm asking you guys. So just run the fuel line to the TB? Thanx again.

Chris

 

So what do i do with the thing in pic 1? Cap all three off and call it good?

Chris

 

Sorry to be a bother but thanx so much, I haven't ever done this and wanna do it right.

Chris

 

Leave 4 alone. If you cap it, the car will smoke like hell.
I cant tell what 5 is.
6 is the fuel lines. Remove them at the hard lines on the frame rail, and run new rubber line. The one from the fuel filter goes to pic 3, the other one is the return from the secondary rail in pic 2.

 

That will work, I took it off and made a plate for it.

Also, ther eis a vac nipple thats nearly hidden on the lower intake. Look between the primary injectors, its sticking straight up, and its really hard to see.

 

Alright thanx Felix, so don't do anything at all to pic 4? And pic 5 is the thing that comes off the oil fill tube. I dont know what it does or what to do with it. thanx soo much again. And thats it right? I don't need to do anything else to the block vaccum wise right?

Cap this?

Chris

 

4 and 5 do about the same thing. You can cap one or the other, just not both of them. If you cap them both, the car will smoke like a bitch. I found that out the hard way.

 

Yes. The only vacuum lines under the intake will be for the oil injectors and the FPR line will be on the backside.
