Hey guys,
i see these things on ebay a lot:
http://www.ebay.com....=item43b2bb31eb
i know the theory of it being better cause your using cooler oil from the filter housing instead of oil thats been up through the head first and all.
but are there other benifits or draw backs?
are there any effects of blocking the oil feed from the head when running this?

By blocking the head port you will have more oil in your head falling back to the sump. the oil from the housing well provide cleaner, cooler and higher pressure oil. Good for bearing journal turbos.

Turbo is fed before the cams in the stock setup. All you are doing is pinching oil from before the crank...
Doesn't make that big a difference IMO.

Pressure at the head is minimal. Remember, the stock distribution block is simply that, no valves or springs too regulate pressure.
I use to use the turbo feed as my oil pressure sender point and it only saw about 5psi at idle and 1 bar at high load. Whereas the oil filter housing saw 15psi at idle and 85 psi at high load.
Mind you this was with a ported housing and no balance shafts. Still a good comparison between the two points

High pressure and high volume without a large enough drain will cause a pressure build up inside a journal bearing turbo which will force oil past the seals killing it.
Td05 turbos fed from the head actually have a restrictor built into the feed line.
If you feed from the oil filter housing I'd make a larger drain for it.

How much time do you spend in a parking lot with your performance car? If you do a lot of parking lot driving, and hang out in parking lots, chances are you are a ricer, go home and read import tuner. If you’re complaining about noise you should not be modifying your car. You should also consider no longer being a man, please hand in your genitals at the door.

i hate not getting notified on replies!
anyway. the stock drain is pretty big? sure it would flow that much oil even under pressure to pressurize the turbo itself?
i just figured cooler cleaner oil cant be bad, and keeps a bit more up the top end also.
thanks for your thoughts guys.

People often need to run a restrictor when feeding from the OFH. Ball bearing turbos run a smaller restrictor than journal bearing due to requiring less oil, some have it built in so check that.
Garrett and pte journal bearing turbos are known to often blow seals when running too much oil pressure and/or too small drain. And fry if there not enough oil. Holsets need large drains as well.
So it needs to be checked at idle and full load when experimenting with different size restrictors.

Bumping this topic as I'm in the same kind situation.
Ive just installed a TD05 onto the Galant, and stupidly decided to use the banjo's and oil feed line that came with the kit which feeds from the head, i now have a small leak from the oil feed at the base of the turbo.
I was going to use the old feed off the old turbo (Precession) which is a braided line -4 from the OFH, what size restrictor is recomended if at all to prevent blowing the seals? or is there to many variables of pressure depending on balanced shaft installed/removed, mods ect ect.
From what im reading the guys in the states recommended to take the feed from the head if its a journal bearing and from the OFH for Ball bearings with appropriate restrictor.
Id like to take it from the housing as I have the line ready to go, if not Ill make up a new line and take it from the head to be on the safe side.
Cheers,
