I am currently in the process of removing everyting in the engine bay that isnt needed. Installing Haltech, T04e, FMIC, did the TB mod and blockoff plates. I know there is like 4-5 vacume lines that need to stay. Can someone list them out just so i dont forget any?

Thanks

fuel pressure regulator, boost sensor, blowoff valve trigger, boost gage if you have an aftermarket one, and assuming everythign else is gone, plug all the extra holes. You can do so ont he throttle body,, by flipping the black spacer plate backwards. IT blocks off all holes except one; backside, bottom nipple, remians open and must get blocked off.
Oh, and leave one or both of your oil fill neck vent nipples open...it might spill out a little oil over a long time, but its a lot better than causing smoke and pressure from capping them off.

And filtered air lines for oil injector tops and injector airbleed sockets, right? Its 3.5/4mm size "vacuum" tubing as well.

And of course, you probably want to keep your vacuum boosted brakes :-) so the big line and checkvalve for that stays.

Maybe vent the fuel tank to charcoal cannister metal line to outside of the engine bay w/ some "vacuum" tubing as well?

I'm in the midst of the same deal. I'm using silicone tube w/ stainless steel zip ties (won't get soft and loose the spring tesion when they get hot unlike the nylon ones). Once I have the lengths figured out I might go w/ some better tube like Viton.

UH, maybe I ve misunderstood you here, but this sounds like it'd creat a lot of vacuum leaks.

Each of the nipples you describe would expose engine vacuum to atmosphere, otherwise known as a vacuum leak, filter or no.
I took my oil injectors off, and put bolts in their place. IF you are running strictly premix, you should do the same. IF you are running hte OMP, then leave the 4 way splitter, and the master vacuum line, and hook it up somewhere. From what I understood he(and you) were going premix only.

My car without emissions has the vac hose that goes to the oil inj, the FPR, the pressure sensor, and one more that im too drunk to remember

anyone know which are needed for an N/A? No belt-driven crap except the Alternator.

Pressure sensor and FPR. unless youre runnign stock OMP, then you need those lines too. oh, cruise and automatic require vacuum lines too on NA's but who runs that stuff?

The hoses on the oil injector tops and injector air bleeds do not get vacuum. This is precisely why the FSM calls them "air hoses" instead of vacuum hoses- as in chapter 1, assemby "Install the air hose assembly and connect the hoses to the oil nozzles." and a neat little picture of the 4 into 1 "vacuum" splitter being installed onto oil injectors.

They attach to the throttle body on a nipple that is fed not by a vacuum port perpendicular to airflow, but by an orfice open to airflow w/ no Bernulli affect- as in roughly parallel to airflow.

does it works both on NA and TII ? i mean blocking nipples by turning spacer backwards....

could someone post picture where will be shown which nipples will be blocked doing it and which will stay open ?

I just went to pick up the bolts to fill the oil injector holes....And the fittings to make the turbo oiling lines...Getting ready to unhook the entire harness in the car in a few and going from there....

Thanks for all the help guys
