VL Turbo Water and Oil line connection

[VL_Turbo]

Could someone please help me with what goes where. 

Attached are pics.
Which are:
- Coolant feed
- coolant return
- oil feed 
- oil return 

Can only see 3 lines from the stock turbo. Where does the water return connect on the turbo please. This is from a RB30 VL.

Thanks heaps

I'm not sure about flow direction, I think what you have marked as water feed is water return. Water feed likely comes off a second prong at the side of the thermostat housing  (the other goes to heater core).

Yellow is the oil return. Oil supply will be on the opposite side (the top, which is underneath the turbo in the photo.

The other two are water in and out, and it probably doesn't really matter which is which on the turbo itself (seeing as they are arranged horizontally) but obviously one will line up with the block fitting via its hard line and the other will go to the supply, likely via some extra (longer, possibly missing) lines, as stated by @Duncan above.

 Could someone please confirm with me with pics? Would be greatly appreciated👍🙏

I don't know. As I said, it realistically doesn't matter anyway. And I also said that the hard pipes you have will somewhat dictate where they go and what they connect to.

Reasonably sure its the port on wastegate side thats the coolant out.

Also doesn't really matter. It just flows across the core.  Ideally the out port is a bit higher than the in port to get some thermo syphon action when engine shut off, but wouldn't lose sleep over it

Donut doesn't matter if I put the coolant feed into the top or bottom connection into the block?

[Ben C34]

Have you got your head around the oil feed and return yet?

What do you mean top or bottom connection on block?

You have posted a picture that clearly labels the ports on that side. There is one for coolant and it's the supply. What bottom connection are you talking about?

[Ben C34]

This was extremely easy to find

Where the water feed is there is another bolt below that, can water feed connect to either? I'm unsure of water return, would that connect to heater hose? If yes does anyone have a pic? Cheers

[Ben C34]

Im sure thats the same water gallery with both plugs.

You can't have the feed and return at the same place, there would be no flow.

There is a reason why the factory have the return go elsewhere.

Does someone have a pic if the coolant heater hose pls? Need to t piece for turbo return. Thanks 

[VL_Turbo]

Could someone please confirm this is where  it-piece for coolant return? Also, if you could confirm the size would be great🙏

Hi all, in the process of putting the afm in the intercooler piping 2.5 inch, could someone please let me know how they have connected the afm in the piping? Did you use some kind of an adaptor? If yes, what is it called and where can I get it from ? TIA.

red Vl is a sample of how I would like to setup my AFM. Thanks

Don't put the Z32 in the cooler pipe. (Is that a Z32? It doesn't look like a VL AFM, but my memory for them is not great). You have to cut the plastic housing up and find a way to glue/hose clamp it onto the pipe. There are no useful "adapter" for something that has a hose barb at one end and a 4 bolt flange at the other.

You could make a matching 4 bolt flange that has a hose barb on it and insert the whole AFM into the boost pipe using 2x silicone joiners, but then you would have 4 more hose clamps heady to pop off. And the hose barb on the AFM is not intended to clamp a hose against boost - it's designed to live on the suction side of the turbo.

The correct course of action is to buy a blade style AFM (ie VQ or VR) and an alloy mounting boss (available off the shelf almost everywhere) that can be welded direct onto an alloy cooler pipe.

Don't argue. There are a bunch of real shit ways to do this, and a good way.
