Damn nice work. Subscribing to see the rest of the work.

I think more realistically I am expecting around 350 torque and 300 rwhp. But anyway...

That's reasonable. Must be running fairly low boost.
The manifold confuses me though. Where the hell are you putting it?

I expect to run around 12 psi to start, so yeah, fairly low. The manifold is attached to the right side of the engine and the turbo mounts under it.
Did some preliminary mock up to get an idea of how the turbo is going to hang under the manifold... everything looks good to clear the motor mount and I am now about 90% sure I can make the helix fit.
Replaced valve cover gasket, front main seal, and cam seals. Also replaced JDM water pump and housing with a USDM pump and housing.
Had to fix the dents in the oil pan, man was this thing dropped pretty hard.

...and she's in the operating room. WARNING: Shameless shop plug below! 
Getting a visual comparison of the helix placement on MY engine...
Final engine prep is tomorrow, then the truck comes apart Friday morning.

What's the point of the helix? It looks pretty awesome but I'm not sure I understand why it's needed.

Because I'm tired of doing things because they are needed. I want to do something because I want to. The whole project is two vehicles "spliced" together. It's a theme thing I guess. It's art. The helix's point? To look cool. Hopefully it does in fact turn out that way. If not, I won't use it. I already have two other simpler and more standard alternative designs on the drawing board in case I don't like it.

On a side note, I did a state inspection on a 2010 GTR yesterday. Mother of God that car is fast...

What is the point on the helix? Why is it needed for the motor?
Not trying to be rude, just don't understand it. I like the uniqueness of the motor in the jeep though.

@peej... ummm... direct your eyes to my last post 8" above this one sir, and you shall find your answer.
So today was technically day one in the shop I guess... nothing more than prepping the powerplant and transmission to go in the Jeep. Had to add a threaded hole in the tranny where the toyo version was missing a bolt hole, repaired a mounting tab for the alternator to the block, and am still working on getting all the fittings in place for connecting oil, coolant, fuel, and air flow throughout the motor. All I have left is the fuel fittings and deleting a few more vac/boost lines and capping some extra coolant piping/hoses. Transmission is now mounted to the block, but I still need to install the TC to flywheel bolts. Already took several layers of skin off and shed a little blood, so we're of to a good yet typical start. Set it on the floor for the night, and will be back in there between 6 and 7 in the morning. Here. We. Go.
My motor has balls.

Is the 2J's front sump oil pan going to be an issue with your 4x4 front axle?

Yeah I dunno yet. Possible. I can put on a rear sump like the Supras have if needed... not that I have that option IMMEDIATELY available to me though...
So the 4.0, AW4, and 231 are out. I'll be figuring out the 2J mounting situation in the am. The mounts on the engine are pretty close front to back on the passenger side, and about 4" different on the drivers side. Yuck. Vertically they are WAY different, since the 2J is normally mounted to a cross member with independent suspension up front. MORE YUCK. I may have to make 4 mounts... the two that bolt to the engine and the two that bolt to the chassis...with the actual rubber mounts in between. FML. It will be totally worth it though, I know it. I expect that will take all day tomorrow, if not the rest of the weekend, especially since I may jig the final mounting bracket solutions so they can be recreated. I'd like to be able to redo this entire build on another Jeep in relatively short order. Boost Logic Jeep you say? Supra of the desert you say? Maybe...
Everyone seems to think a v8 is the only way to get the torque Jeepers want, but I am expecting to reach full boost by 2500 rpm... and have it taper off quickly... so I should see higher torque numbers and lower actual "horsepower" since this setup won't be capable of flowing enough at the upper rpm range. It's whatever though, I'm not too worried about the upper range of the power band...CAUSE IT'S A JEEP. Also, since the boost will come on relatively gradually AND the power is going through an auto, I expect the d35 to hold up ok. I'm not running larger diameter tires. I'm looking into a d44 or Ford rear just in case I decide for some silly reason to bolt on a BL manifold with a garret billet 71mm turbo or something retarded like that... cause that's an option...hehehe. So yeah, I'm done talking about it for today. Here are the pics. GIVE ME GAPE, LOL!

Day 3.... holy crap. Some things are working out better than expected, like the engine/trans fitment in the bay/tunnel... but other things are not going as well like the front sump wanting to sit all over the panhard bar and steering arm. I'm searching for a rear sump oil pan. Passenger side mount complete, and the driver's side is done on the chassis side...still have to build the motor mount. Tomorrow I plan on finishing the mounting, then reinstalling the xfer case and trans shift linkage along with the drive shafts. Then I clean up and park it and work on it as I can from there on out.
I did not jig either mount. Passenger side is exactly stock on the chassis side... driver's side is moved back around 6" or so. 2J oil filter and A/C compressor sit right where the XJ motor mount bracket and mount are.

Also, because of the mount situation I don't think there is any way the helix is gonna work in the manifold. I'm gonna have to do the norm...find the best place for the turbo to be and build the manifold to it, however I can get it there. 
Whatever.
Whatever.
Keep it up! So it looks like you are using stock replacement MMs? Those unsupported triangles are notorious for cracking under torque(which then stresses the headers--why you see so many cracked header threads) and your turbo will have 2x+ the torque, so look into Brown Dog or MOREs.

yup my 4.0 snapped the motor mount bracket bolts, had to drill them out, i upgraded to a brown dog bracket and haven't had a problem.

So I spent all day building 1 mount bracket pretty much. I don't like it, and really I want to do the mounts again later. Trouble is I'm old enough to know that I'm probably lying to myself. But it's a bunch of whatever cause there's A MUTHA_FU@KIN' 2J IN MY JEEP!
