i've been going through the pelican parts diagrams and i can't understand why i have to have that large ugly air cleaner and why i have to route the fan shroud to it and blah blah blah.

again i come from the vw bug world and hell we don't have any of this junk.
now i can understand the distributor vaccum line and the throttle body vaccum line. buy what the hell is all that other stuff?
i want to take the deceleration valve out and the air cleaner off. i pretty much just want a motor that is the bare basics of what i need. i just want injectors and a pod filter ontop of the intake system... is that so hard to do?

well if my car was already running i would just remove lines and plug stuff up. problems is i bought the car in pieces. so my injectors are being rebuilt, and i wanna get rid of all the un-necessary junk while the motor is out and on a bench. has no one already done this?

damn might just have to have bob johns look at this for me (IMG:style_emoticons/default/sad.gif) thats gonna cost a small fortune :\

The 2.0L D-jet relys heavily upon the vacum lines. Have the wrong one off and it won't start or run. Others will make it scream until you put it back on. This is a task you need to undertake with the motor running, or find someone else who has already done it to guide you in the right direction.

Lets see... (IMG:style_emoticons/default/idea.gif)

You need them all!

There is not one you can remove without it affecting something negatively - drivability, MPS life, gas fumes. Not one robs power either. I vote to live with them.

That big airbox with the filter...that will save you motor better than those K&Ns...

You can remove the Decel valve and both lines
You can remove the cold start AAR valve and both lines

Let me back up and make this easy.
There is one you must have. You must have the large vacuum line from the MPS to the intake plenum (not the air cleaner) in place.

All other lines are optional...honestly. (flame on boys...btdt)
I would suggest you leave the distributor advance line in place..
You can remove the distributor retard line and plug that port.

Some of the lines increase drivability, some make it easier to start, some make it easier on the MPS (though I dont see alot of real world evidence)
Some make it more emmissions friendly.


Depending upon where you live...the system may need to be completely setup as original to pass registration testing...
Its a pretty easy system to learn...

I run no decel valve, and no AAR unit...car runs fine.

I too passed thru the VW, aka Type I world. I remember reading Jake Raby's comments re: the Type I vs. the Type IV and think to myself "What a pompous prick"! Then I bought a 914 w the Type IV. What a difference. Jake was right.
I think that once you get that engine running you will stop worrying about appearance and begin thinking performance!

You want to eliminate important parts of a carefully designed system because it looks cluttered? You want to put a POS "bird stopper" sock air filter in place of one that actually works extremely well? You want to take the advice of "good old buddies in the porsche club" who think they remember doing this stuff in the "70's-80's" but they can't remember what they did. You sound like someone who spends way too much time reading so called "enthusiast magazines" and cruising the internet, believing what you read because, after all, it's on the web so it must be true. There are a number of real 914 experts here. I suggest you ask them about what you want to do, and listen to their answers.

I was eagerly awaiting the Cap'ns response on this and he came through in rare form!

Honestly there is stuff you could probably eliminate, but when the djet system is dialed in it works extremely well. If you don't understand why its there, I would focus on learning what does what in the system and why, instead of eliminating things you don't understand. That is kind of the tail wagging the dog after all. Make it operate correctly and you probably won't turn back.

Funny discourse, thanks!

Just an opinion, but if you play with bundling and routing you can have a good looking motor without all the negatives that removing vacuum lines will result in.

LEAVE THEM ON! (IMG:style_emoticons/default/first.gif)
