Default Turbo BOV question and Water Line for Turbo

1990 240 pursuing plus t

1. If a turbo has had the internal bov removed then would that mean I need to install a bov externally?

Also the wastegate doesn’t come with the turbo. This is okay because I have to reclock the turbo anyway with a bracket fab’d for the wastegate to fit properly. I can buy one for it.

2. For the turbo lines I have it decently understood. I understand the oil feed and return.
The coolant/water line for the 16t I can’t find much info on. What is the setup??

Thanks

2. You'll need 2 of these three hoses. One is the radiator hose that tees into the turbo water line and the other goes from the expansion tank to the radiator and tees into the turbo.

Ok thanks sounds good.

And can anyone help with number 1??

If the internal
Bov on the 16t is removed, what will I need to do? Add a bov on the IC line?

Thanks

Yes, if the internal bypass valve in the 16T, then it would be wise to run an external bypass valve in its place. Probably easier to fit a new internal than external. I run 17 psi from my 16T all day and it runs the stock CBV.

The owner states he welded over the internal bov. Now I’m thinking I won’t be able to add an internal. I may just have to forget this turbo.

Thoughts?

Also where does the line from the bov on turbo run to?

Thanks

If the wastegate has been welded shut you'll have to run an external wastegate. So you can reclock however you want and not have to worry about a bracket for the internal gate arm.

Wastegate and bov are two different things. Wastegate holes are good and ready for wastegate bolt on.

BOV is welded over, bolt holes and all. So I would have to install and external bov because even with cbv it still wouldn’t run correct, right?

Thanks

You'll need a BOV that recircs

It will run fine without a CBV or BOV, but the turbo will flutter and "kill the turbo prematurely". I would get a newer unmolested turbo personally but you can run yours with an in-line blow off valve.

Check out a Bosch recirculating bypass valve like 0 280 142 110. They work well and are relatively cheap.

My experience is that the LH 2.4 would stall with a BOV to atmosphere.

It can learn around it, or you can move the AMM post turbo.

Post turbo is just silly and at the time it was my DD so I wasn’t going wait for it to “learn around it”. Far easier just to grab a Bosch recirc from a turbo Audi and plumb it in correctly.

I agree, I too went back with the CBV.

Duder or whoever, how would I incorporate this Bosch valve into my set up with turbo situation?

Thanks

Here's how I did mine, Holset hx30 and used the stock airbox.

Damn yea I see I’m going to have to fab some openings coming off the AMM plumbing and IC plumbing to set up this valve. Where does the small vacuum line go to?

Intake manifold.
There was a couple of years of 740s that had Garrett turbos. You can get those components. Or just get a new compressor housing.

Ok guys so I got ahold of a 13t turbo for 60$. It has the wastegate and internal BOV.

With that being said, where do the lines need to run from each?

Also, will I have to reclock this for the 240 and 90+??

Thanks

What do you mean? Headlines or vacuum lines? Bypass valve needs a line running to intake manifold. Wastegate actuator needs a smaller short line running from compressor housing.

And yes, it needs to be re clocked if it’s not in the same orientation as the stock one.

What nipple on intake for BOV?

Wastegate to where on compressor housing?

I’m also having trouble finding the water hard lines that connect to turbo. I know about the hose set up kit but I’m talking about the actual hard line feed and return.

Thanks

Doesn’t matter which nipple the CBV goes to on the intake manifold as long as it fits tightly and is post throttle body.

The wastegate line should go from wastegate to nipple on the compressor housing. Let me find a pic..

And I could definitely be wrong but I think the hard lines are the same for coolant on the 13t and 13c..but you’ll have to check.

I went with all custom feed and return so I can’t helo much there, though I would think that they are the same as long as the CHRA is in the same orientation as a stock 13c. I’m also almost positive that the thread pitches are all the same. But again, someone else needs to clarify.

Edit: post number 12 in this thread, you can see the small black line on the compressor housing going to the wastegate actuator
