I am closing in on the end of this build.
The latest problem is understanding the oil feeds on the T3 turbo.
Mine is a sierra cosworth 205 block with 4x4 head in a 2wd with a 2wd exhaust manifold.
I thought i had the oil feed pipes .
The one on the outside furthest away from the block i have the pipe were does this lead to?
The one on the inner of the turbo nearest the block.
The pipes didn't fit so i bought a group a oil feed attachment .
This question is what is the pipe that attaches to it and were does it go?

is this the correct pipe to buy

If i can have these questions answered i will be a little nearer.

 

I think you're a little confused.

There is an oil feed pipe, that goes into the top of the turbo, and an oil return from the bottom of the turbo that goes into the sump. The 2 ebay links are both for the oil feed to the turbo. The link for the hose is a 2wd specification oil feed, which fits onto the adaptor near the starter motor along with the oil pressure switch (like this : http://cgi.ebay.co.uk/Ford-Cosworth-Engine-Escort-RS-Turbo-Oil-Feed-Adaptor-/310305509372?pt=UK_CarsParts_Vehicles_CarParts_SM& hash=item483fa64ffc). The 4x4 specification turbo oil feed instead comes from the side of the cylinder head.

You can either :
1. buy a standard 4x4 oil feed hose, and not fit the adaptor into the block above the starter motor as used on 2wd vehicles, and screw the oil pressure switch straight into the block, or
2. blank off the turbo oil feed in the side of the 4x4 cylinder head, and use a standard 2wd spec oil feed hose (as per your ebay link) and use the standard 2wd adaptor in the side of the block above the starter motor (into which the oil pressure switch will screw).

Whichever option you choose, the "GrpA turbo oil feed" from the ebay link is no good to you - it won't fit with standard hoses. If you want to use it, you'll have to make up your own hoses. What you will need to allow you to use standard hoses is one of these in the top of your turbo, if you haven't already got one :

The metal pipes that fit onto the sides of the turbo (using banjo bolts) are for water cooling. The one closest the the head is the feed, which comes from the thermostat housing, The one furthest from the head is the return, which goes back to the header tank.

 

The pipes i was looking at are the ones with two bolt holes at the side.
he ones that were shown ,though i believe you are single screw in affairs.
I have the water banjoes.
Its the two connections with two bolt holes at either side i am interested in at the moment.

 

The standard turbo oil feed at the top does not use the 2 threaded holes as standard - the fitting in my eBay link above is what goes in the top.

The standard oil return in the bottom of the turbo does bolt on, using the 2 M8 tapped holes. It's a metal pipe with a flange to bolt to the turbo, onto which goes a rubber hose to the sump.

 

Yep ive seen the light.
I just seen a close up of the top oil feed.
The holes in the flanges are not used.

 

Is the 2wd or 4x4 turbo oil feed the better method.
If there is a better oil feed i will use that.
If not i will flip a coin.

 

I'd personally go for the 2wd oil feed, my reasons being, the oil will be cooler, without having picked up heat on it's way up through top the head.
My other reason is there is less opportunity to pick up any debris floating around the lube system, as it doesn't come into contact with as much of it.

Thankyou.
all makes sence and will keep the mechanics at bay for another five minutes untill they find there next problem.

 

An awsome site for al things car hydraulic is BGC Motorsport, I was there yesterday having a pipe made while I waited, Brian the owner even made some suggestions that saved me around Ł30 needing to be spent with him, so honest as the day is long, he doesn't push sales, he's on the net, I seriously don't know what connector etc he hasn't got, does mail order as well.
Mods, please note I am in no way connected to BGC, and this was the first time I'd met the owner, just trying to be helpful, as I got the serious run around from every one over pipes lately, but straightforward at BGC.

Thankyou i will use hime once i have the car running.
I have the parts i need for the turbo now but will will keep a note of his business name for any future occurances.
