Greddy Turbo Hose Routing
I just want to get some input on the 3 hoses that was supposed to be connected to the intake. The way greddy meant it was:
Airinx filter ===> Jet Air Fuel Mixing Hose
air intake pipe (nipple 1) ===> Oil Fill
air intake pipe (nipple 2) ===> Metering Oil Pump Hose
There is a complication in which the fitting that was supposed to connect to the Jet Air Fuel mixing hose to my airinx was lost....
---------------------------
This is how my hose setup is when it came from the installer:
air intake pipe (nipple 1) ===> catch can
catch can ==> tee
tee => oil fill
tee => another tee
2nd tee ==> Jet Air Fuel Mixing Hose, Metering Oil Pump Hose
air intake pipe (nipple 2) ===> Sealed off
Just want to know whether there is any negative effects by running this...
----------------------------
Coincidentally i tried rerouting the hoses a different way
air intake pipe (nipple 1) ===> catch can
catch can ==> oil fill
air intake pipe (nipple 2) ===> tee
tee => Metering Oil Pump Hose
tee => Jet Air Fuel Mixing Hose
This routing method produced a better response, but it blasted white smoke through the exhaust whenever the car idled for more than about 10 seconds..... So i put it back to what the installer put it at....
------------------------------------------
It is my intention to put it back to the way greddy meant it, just wanna get your opinions whether this is correct:
air intake pipe (nipple 1) ===> catch can
Catch can ==>oil fill
air intake pipe (nipple 2) ===> Metering Oil Pump Hose
Jet Air Fuel Mixing Hose ===> a breather
You think i will still get white smoke if i swap it to this route? Just want to get some input for fear of damaging my turbo...

Don't forget the check valve on the jet air fuel line.

Check Valve? I dont think there was a check valve... The hose is 9mm, i dont think i've seen a check valve that size...

Jet Air Fuel Mixing Hose ===> Pipe before throttle body (pressure side)
Link to instructions
EDIT: you don't need the check valve

So now i get a 10 nipple... and fit it in there?
Or do i stick with the breather...?
has anyone done this rerouting of the hose?
What about the intake manifold plate... has anyone done it?

I moved the jet air line to a breather... and out came the white smoke...
I am almost positive i took the right hose, what happens if it's the othery way round?
Should i just put it back to the way it was?

it would be nice if someone could provide a nice illustration of a hose routing diagram for turbocharging the 8. that would solve a lot of these "how and where to route hoses" questions
just my 2cents. im also having hose routing issues with my turbo setup.
thanks,
chris

There are only three hoses, so let's start with an easy one, like the oil fill spout:
This one obviously goes from the the oil fill spout to a catch can then out of the catch can to the pipe in between the air filter and the inlet of the turbo.
The next one is the metering oil line:
This line, when traced back....use your fingers to tug on the line to trace it.....this will lead you behind the plastic intake manifold. You might be able to put your hand between the firewall and intake manifold and reach down to grab this hose. Just pull on it and you'll know if you have the right hose. Once you find it, install this one anywhere between the air filter and inlet of the turbo.
Last is the jet air fuel mixing nozzle line:
You have two options....1. install it behind the airfilter and place a check valve inline ( to prevent boost leak) OR 2. route it to the 3" aluminum intercooling pipe, before the throttle body, where a BOV should be, and have some one weld a barb onto this pipe, it is fairly simple and you get to actually use the jet air nozzle hooked up this way.
What ever you do, make sure to run each hose seperately, don't tee all of them together.

Jet air fuel hose
With the breather = white smoke...
With the hose connected to an inlet in the pipe... = white smoke...
Attached is a picture of the setup i tred... I already put it back to what it was before, coz i need to drive the car....
Any idea what could be the cause?

Consider the functions of the pipes:
-the engine breather hose is taking any vapours out of the motor when they are above atmospheric pressure and so preventing pressure build up,
-the jet air pipe provides air at about atmospheric pressure to nozzles in the inlet port the purpose of which is to improve fuel atomisation at low engine speeds,
-the oil injection air provides air at atmospheric pressure to the inlet of the oil injector nozzles--the purpose being to prevent a vacuum getting to the oil supply.The reason being that if you do not break that vacuum you will suck oil into the combustion chambers.
My guess would be that you are not getting air to your oil injectors and so sucking oil into the combustion chambers.

Thanks for the links....
But unfortunately, it's hard for me to procure little items like this... I live in a tiny obscure country... Trying Mazsport now as he will be sending me an interceptor in a bit, so hopefully he can procure one for me....
