Im not an expert welder. So I would need someone to do the work. not to mention the time consuming part of mocking it up to work. I would end up using schedule 40 pipe bends and about a 3/8 to 1/2 inch mount flange at the head. Thats what the book suggest using. So its more of a time consuming process and finding a welder that can work the type of material and garrentee ASE certified welds to handle the temps and no cracking. But before I start doing a manifold, I need to buy the turbo first. I haven't even done that. Other things are taking priority on my jeep.(Lockers, gears, front dana 60 build up and mount, building a strocker).
Now I have thought about buying the turbo, making the manifold, then just make an adapter to bolt to the turbo manifold and act like a regular exhaust till the time comes to do the turbo set up. Basically, I would be using a turbo manifold in replace of the stock manifold for probably a couple of years. So when the time comes to start the project, the hardest (Mechanical) thing is done. Theory is you can use a turbo manifold as a regular exhaust manifold using a bolt up adapter in place of a turbo. Im going to try to see about cost of making one using the materials vs. cost of buying one off of the market.

Thanks for the compliments on my setup, my project is finally out and running! I am working the final kinks out of my system, and busted the rear yoke on my driveshaft on it's first outing in the dirt. It seems that manually selectable hubs need to be manually selected in order to have power to all four wheels... doh!
You are building to overcome the same issue I have, namely hiway power with big tires. Although with your cool Dana 60 axles, you are going to have more losses than I... Thanks for the tip on the book. Like you, other things have a higher priority for me right now.
One tip as I have thought about this - don't buy the Pacesetter header if you want to add the turbo later. The header works great (I am happy with the price and the performance) but it is a long tube header. The headers that Hedman and others are making are 1/3 the length of the Pacesetter header I got. Price was the main reason for opting for the Pacesetter. If I ever do add a turbo, I will probably have to get a different header because my downtubes don't fully converge until about 2' in front of the catalytic converter.
Thanks for the other tips, I am going to have to print this entire thread for future reference...

Why bother with a turbo manifold just mount the turbo before the throttle body and pipe to the mani. Or am I gonna blow my manifold apart with a 10-15 psi pull...?

You can do a remote turbo set up, but you will lose some effeciency going into the engine. About 1-1.5 psi plus another 1 psi running an intercooler. You do have a great argument on running a remote system on these motors, Just where are you going to mount the system. Remember, turbos create high temps, so don't mount it next to your fuel lines. Insulate it from the intake manifold, and since you want to run higher then 10 psi; you better make sure you have a strong bottom end and High performance valve seats or your motor will start leaking compressed air every where.

oh no I wont run more then 7-8 psi with a remote mount setup once I hard mount it tho I want to run higher psi but I will have a built Stroker engine by then. As for fuel lines no biggy there as Im rerouting all my lines. Im not to worried about the remote mounts effeciency as it wont be permanent. and if I really wanna get creative Ill make the turbo its own oil cooling system with a catcher and pump and what not. I wont run an intercooler on the remote mount setup ill just use a chemical cooler...(alky injection) which should help with detonation as well.

If you want more info on this thread, go to pirate4x4. click on bullitans, then on Jeep hardcore. You will see a thread on 400 HP turbo 4.0 something along that. It has alot more info. IF any one is interested

Drove my jeep on the hwy and was severly upset with the performance. Thats it!! Im puttin a cheap rebielt turbo on my jeep. Going to buy the pacesetter header, modify it, mount the turbo on the passenger side, run it straight into the TB, no intercooler now, try to source some higher rate fuel injectors for cheep, install a waste gate, turn the boost to about 4 psi, swap out the MAP sensor for a 2 bar unit, Udjustable fuel pressure regulator, 2 1/2 inch exhaust all the way back, and call it a day. Oil lines will be easy. drop the oil pan and mod it for a oil drain back.
This will be fun

Bought me a T3/T4 A/R .60 turbo and intercooler for $200.
Was wondering if someone can tell me what is the ideal trim specs I should be running in my stock Jeep.
I will be running with a Fuel/ Timing controller from Splitsecond if it matters. Also bigger injctors and fuel pump.
I would like to max the boost for this engine. I will up the boost later when I rebuilt the engine with bigger bore and forged pistons.
Thanks

Well my turbo project is in motion. Here is the link: http://www.pirate4x4.com/forum/showthread.php?t=658004
make sure you follow the additional link on my first post at the bottom. I go into detail of the math involved for this system.
the thread is a detailed step by step how to pretty much as well as included speedbumps I ran into.
Its awn like donky kong

ITS ALIVE!!!!
It works. running 5 pounds of boost till I can tune it in. when its in tune, I will turn it up to 7-8. small gremlins, but parts are on order to solve em.
It pulls like a SBC and the torque increase is awsome!!
And all fabbin, designing, and engineering was done by me with some help of the PBB.
