Engine Turbo vacuum connections

Turbo vacuum connections

can anyone give me a quick explanation on how to connect all the vacuum hoses on a turbo kit from those who has sf kit thanks

There is a Vac line that goes from the Vac manifold to the VSV (if you look at the vac routing diagram under the hood you can find it) You need to cut that and insert the plastic "T" into that.

The "T" should have 3 nipples" One goes to the top of the FMU, one goes to the top of the BOV, and the other goes to a boost controller, but you can cap it off if you don't have one yet.

The fresh air soure for the EVAP line is the line that is connected to the stock air box or you CAI...that can just be removed and the nipple it's connected to left open.


Also, make sure that you disconnect the larger hose that goes from the front of the valve cover to the throttlebody area. Cap it on the throttlebody side and vent the other side to atmosphere. If you don’t, the car will probably burn oil.

Sorry if it's unclear....I'll try to help out the best I can....I had SO MUCH trouble with the vac line at first.....mainly beacuse mine were screwed up from the factory....so they weren't right when people were trying to explain it to me. But now they super easy to mess with for me.

how did you run the oil lines??? taped into the oil pan?
also know fo any good places to get a manifold and downpipe for a TDO4E T3/T4 turbo?

I don't know if it's normal...but that's exactly what mine reads....lol at least at idle.

And yeah I ran the return line to the oli pan. I tapped 3 holes for the 3 hole flange......bolted the flange to it..then JB welded it added protection...it's not going anywhere.

I am going to have my car tuned on wednesdday let you know if that is normal
any problems with your kit so far i know you had it for a while now any upgrades?

yeah...it cuts off ocasionally when I'm almost at a stop. I think it's an air/fuel thing.

hrmmm, wonder why my boost guage never reads anything but boost....sits at 0 on idle Anyway, i can vouch for the burning oil thing...its a bitch if you put those things in wrong. Also, do you know where i can pick up an FUM? will any old one do?

i dunno if we installed everything wrong but we both read 20 on boost car is running fine for now but i dunno in the long run lol! tell me how you installed your set up may be i installed it worng thanks

so that thing basically acts as a pump to raise pressure?

right....it raise the fuel pressure depending on how much boost/vac you're running. So if you're set at 8psi then when taking off......at you start move up to 8 psi it will give more fuel depending on what boost level you're at all the way up to 8psi

Thanks a lot, i think all connections are fine. I have the vac/boost gauge. I am only running 5 psi on mine. I like my kit so far. Do you have any idea how to install a apexi turbo timer?

Are you sure it's a vac/ boost guage and not just a boost guage?...lol You're definantely not at 0 vacuum at idle. You can pick up a rising rate ecu at Stafford, theirs are kind of pricey, you can also get one for vortech.

i think i hooked it up in front of the pcv valve and thats why..or something, i'm not really sure where he installed it... not a big deal. So any old FMU from vortech will work? I know the theory behind that, but how do you hoook it up? I'm assuming you need a vacuume line running to it, but where does it connect to the fuel system to boost pressure?

it should not read zero at idle...20 vac is normal..

The one in the picture would work perfect...the nipple on top you would run a vacuum to. the 2 other nozzles are fuel in and fuel out.......all you have to do is tap into the fuel line that goes into the fuel rail...there is only one line so it's not hard.....the only problem is it's a hard line...so you'll have to cut the hard line and hook up a fuel line to both sides of where you cut the hard line the run the 2 newfuel lines you have now to the in and out of the fmu. MAKE SURE ALL CONNETIONS ARE TIGHT. You would be better off getting a new fuelrail at the same time so you could do away with as much of this hard line as possible....but that's up to you...SF has them, if you want to take the chance of buying from them....you probably won't have a problem if it's just a fuelrail.

The one's that SF have have a fuel pump attached to it.....the vortech ones don't....hrmm..wonder why.

no...but I NEED a turbo timer bad.....lol I strongly recommed a vacuum manifold like I have to replace the plactic T you're probably using.....My car runs so much smoother since I put it on....It's awesome.

Yeah i am thinking of getting one of those brass eagle t , i dunno if i said it right.

goldeneagle? that's what I have....they're awesome Here are some shots of my set-up......I've posted these same ones earlier...but o-well

Bear with me...these pics were taken with my camera phone.....


Here is where I mounted my boost gauge...




Here is a shitty shot of my engine bay...



Here is the golden eagle vacuum manifold...



Here is my TurboXS RFL BOV...



Here is the turbo w/ the heat shield they finally sent me...



Here are some not so good shots of the car...

DAMN that T3 is a tight squeese back there. My T-25 has plenty of breathing room. I find it cool they can run the pipes straight over the belts... if youve sen my setup, i put all the IC piping on the driver side and had an intercooler with both outlets on the same side...just different setups i guess

The MFR is the cheapest pkace to get it

it will run you $45 yor the manifold and the brass fitting kit. It comes with anylon "T" but you don't need to use it, since the whole point of getting the vac manifold is to eliminate the "T" . Just take the line that you spliced....take end that come from the intake manifold/TB are and plg that into the big nipple on the side of the vac mainfold....then the other half of the spliced line that goes to the VSV can just gplg into one of the 6 ports off the vac manifold. If you order it make sure to go online and order a lot of silicone vacuum hose. so you can make it a nice neat project. You can go to http://www.hosetechniques.com/catal...by%20the%20foot and order 10 ft of 4mm and 10 ft of 6mm and that will work out great...the 6mm will be a little tight on the big nipple on the vac manifold side but it will work, if you go any bigger....it won't fit on the other port you need to hook it to....lol BTW I ordered the same products from both these websites and had absolutley NO problems

Yeah the pipes are about a 1/4 inch away from the bels.....it worries me some times...but I haven't had any problems so far. So the T-25 is that much smaller huh. Maybe I should have gone with that, because my turbo takes a while to get to full boost...Not reallong, but longer than I'd like it to. Like it's hard for me to set my boost controller because I can't get on it for long periods of time because of all the cops.....so I'd like it to reach full boost sooner, so I would have to be full throttle so long to see what the psi maxes out at. And yes it's CRAMED in there.....I had to break the seal on the firewall and strut tower to get it in there......plus the engine cover doesn't really fit on there to good any more...it hit's the turbo......plus the turbo has melted it right there....lol I think I'll just get one of the supercharger ones.
