Landtank, In meantime can you maybe make the aftermarket exhaust manifold for the non turbo one? I mean better flow compare to the OEM one.

Okay. Your top detail was showing one continuous flange, so I thought maybe you were still trying to incorporate some sort of expansion joint in the pipes. That would be tiddies and beer, but it seems impossible to get a working slip joint that wouldn't leak.

Downey already has them.
Not the down pipe, it just the exhaust manifold.Which, If I buy from Downey I still have to go to local muffler shop to make me new down pipe.

That was a quick drawing to illustrate the design and not a detailed one for manufacturing.
A slip joint is difficult to work into a design like this. If it were cast then it would be a different story. You could source some sealing rings from Toyota as they use them on older motors such as the 2F.
I did spend quite a bit of time on this. I did heat tests on the parts, checked out stress relieving the final product, calculated expansion from heat and shrinkage from welding. Hopefully I'll get some fun from it for a while.

I've tossed around a few ideas but it comes down to getting a commitment from a group of people.
I had thought about doing a group build project. So as I build up my truck others could benefit by getting the in on the items that need to be specially made for our application.
This would be the manifold, down pipe, intake plumbing...ect. This way they could source the common off the shelf items at a later time or look around for bargains and assemble the rest as cheap as possible.
The manifold has a T4 turbo flange and while I bought a 1300.00 turbo there are a slew of budget ones to be had that could save quite a bit.
I'm always open for ideas but realistically getting enough people for a single run of these to get the price down seems unlikely.
Rick, two questions for ya'..
On extreme 4x4 the other day the dude was welding up some exhaust headers. He was talking about using a specific (copper or zinc or something) welding wire material that has a lower melt point as to not affect the metal he was welding to. Make sense? Have any idea what type of wire he is talking about?
Also, what about using the stock manifold as it is and modifying it to accept the turbo? Kinda like jgwinc did on his build? https://forum.ih8mud.com/80-series-tech/190765-newbie-pix.html

I have no idea about anything welding related. I'm having a professional do the work and he's confident that the joints will stand up to whatever the engine throws at it.
While jgwin's design got a turbo on the truck it just isn't anything I'm interested in. Too many compromises, the first being the loss of the factory air filter.

Looking forward to see this build finished. I have cash in hand, would love to get my hands on a manifold, dp, and intake piping!
Hey great threat and amazing engineering and enginuity. Have you seen this one? Probably and it doesn't have provisions for a blow off valve like yours but it is cast iron with an expansion sleeve. Without showing a price im not sure if they are in production yet or if they will even make it into production. Just a heads up.

I like that manifold.
My bet is that the price and shipping would kill the deal.

Spicer'92, the main problem with that manifold is that it's an internal waste gate type. While this is what AVO and Safari use it requires a custom casting to get the down pipe on the turbo in the space it occupies.
I looked into using an internal unit and it's just not practical.

What are the other compromises that i made?
Over the years i have built many log style manifolds and to date i have always had problems with them cracking some last a littile longer if you take extra care(back purgeing and or relief cutting the head flange ) the problem, in my opinion is we just couldn't get a filler rod that could handel the diffrence in the expansion rate between the cast weld L and the weld filler.
My welded job got me 15k miles.
If anyone can make this one off manifold work its Rick
However that y adapter using the oe manifold is trick and if the Y cracks its not nearly as big a deal to replace as an entire manifold. I like it. The Y must flow better than any log and I bet EGT's would reflect that.
And although I feel good having the oe filter on my truck again in place of the K&N I must say the oe airbox gets hotter than hell so close and so large next to the manifold. All the shielding in the world will not negate its massive heat sink affect.
Rick likes to be told it wont work. I think it motivates him

Ebay sells adapters that bolt to the maifold allowing one to run an external wastegate

If the adapter bolts between the manifold and the turbo then you'll have clearance issues with the PS motor mount.
I'm not at all telling him it won't work ,I think everyone should do what they want no matter what someone else says I just wanted to know what i left out of my build other than the stock air bucket.
As for my opinion on the manifold it's just my experience with this style of S40 weld L construction.

it's not your specific turbo build but the truck as a whole
omit factory air cleaner
omit snorkel
omit second battery tray
omit York OBA
and with the turbo underneath I think managing engine bay temps is a little easier.
I didn't think you were telling me I was wrong, in fact your one of the few, maybe the only one, that offered some insight into why you don't favor this type of build. If/when it fails maybe you could give me some insight as to why.
My earlier post was as I was going out the door to catch a 5:00 am flight and now that my connecting is delayed I have some time to respond better.
