It'll be a killer street/drag setup for certain.
Road racing, not so much. You might want to revisit your front diff choices as the GM front diffs are far from performance oriented in that realm. Further, with a 4L80 and transfercase and turbo, your gonna be putting on a bit of poundage and theres going to be some heat concerns with the tight fits.
What about a modified oilpan with a driveshaft through pan and set the engine far back into more of a front-mid-engine setup?
There might be some options with retrofitting a porsche front axle out of a C4S, it's been a while since I've seen one; but I *think* they are rather small.
It's very challenging to have a front and low V# longitudinally mounted for 4wd use. I always imagined it as being a front mid-engine with the the trans output being a little behind the center line. Transfer case with small diameter driveshaft then running hugged next to the block on the passenger side. Granted, AC might go bye bye. Basically very similar to the new gtr, but it's still a bit too high mounted.

all the pass through axle systems I have seen do not get the axle any higher than I have it now.
My engine is no higher in the engine bay than the other 240 to lsx swappers.
my engine is further back than most 240 to lsx swappers.
Most of the added weight is in the middle of the car and low down.
the 4l80 will have a 5 clutch torque converter that will be locked 2-4th gears for road racing. this will keep the converter from super heating the fluid which will have a large dedicated and ducted cooler and a fan if needed.
the car will run a small diameter drive shaft. tucked next to the block but on the drivers side.
c4s would be too hard to make work. its not the configuration i need.
I was originally going to use bmw 330ix stuff but its too week. this diff is larger than most car front diffs but smaller than most truck stuff. so it will hold up to any thing I throw at it. It also came in many ratios and is cheap.
and again Im starting at about 2650lbs. even with awd it will weigh less than any thing that came from the factory with an lsx.

OKcrusing I did some asking around, and evo sti and gtr guys swear by torsen lsd's in the front. 
GM 7.2 only has a locker available. (obviously that won't work) I did a bit of research and the front differential for an explorer has a torsen unit available. I guess I'm going to switch. Dana 35 is 7.56 ring gear so its a bit larger but it has a low pinion vs. the high of the gm 7.2 and it comes in 3.55 gear ratio. I wont need to run staggered tires. the axles on the wheel end fit into the hubs I already have. I'll get some pics up once it is in.

quick update: front suspension is in, front axle has switched to tbss set up that is also in the transfercase is in, looking to get the front drive shaft in today. I still need to make across member with a transmission mount, but the motor mounts are so strong that they will support the 4l80 and a t-case hanging of the back. While I'm in the garage I'm going to snap some pictures
I made three different sets of motor and from axle mounts before deciding that this is the best route. the engine had to move up relative to the chassis and now sits at a 7 degree slant which I'm not found of but i think it will be fine.

Wow cool project. Should be a rocket. I have a somewhat off topic question. About the alternator mounting. Is that all stock ls stuff except for the brackets to hold the alternator. Also what belt are you using. The setup looks great. Would probably get alot of guys out the cross member bind.

Ill go snap pics right now I have been slacking and bench racing. some things have changed. New engine in the machine shop now getting forged bottom end and going twins now, bigger brakes too. give me few minutes to show the current progress.

current parts:
-oil pan- trail blazer ss
-front differential- gmc envoy with axle disconnect (thats right I can drive this thing in 2wd still
, and yes the transfer case will tolerate that. typhoon guys pull the front drive shaft all the time no problem.) 3.42 gears 305/30/18 tires
-cv axles- driver 98+ s10 passenger 98+ s10 zr2
-steering knuckles- chevy cobalt
-hub assemblies- 86ish cutlass sierra with hd suspension
-ball joints 05 cobalt
-lower control arm- custom fabricated by me/ tein lateral links
-engine mounts/ lower control arm pick up- fabricated by me
- steering rack is not on yet and actually i have to look in what I'm going to use. I have bought at least 6 racks that wont work. The one I have now seems as if it will work with modification, I know for sure power steering ain't going to happen, no room. the steering shaft will actually pass in between the axle input and the engine block apox 2 inches of clearance after cutting an ear off.
-engine is mahle/eagle forged 347 still in the machine shop/ ported heads big bump stick/ twin tc76 ect. looking for 1000 awhp
-transmission is a 4l80 with a trans go hd-3 stick conversion
-torque converter will be a precision 5 clutch (so it can operate locked for road course driving, and keep the heat in check. poor mans sequential
)
- transfer case is syclone/typhoon/bravada with a George Blake/Prime gears custom input shaft/adapter to fit 4l80
-front drive shaft- astro van
- rear drive shaft- custom made gm 32 spline to Nissan 4 bolt flange
- rear differential- Infinity Q45 92-96 3.55 gears 335/30/18 tires
-rear cv axles left 300zxtt left 92-96 q45 used on the right
- rear hub assemblies 300zx tt
brakes front 14 inch with brembo f40 4 piston calipers, rear 13 inch with brenbo lotus 4 piston calipers 2piece baer rotors front and rear
-wheels axis 18x10.5 front and widened 18x12 rear
-shifter- b&m pro ratchet (moves like a sequential)

Now that is definitely an "out there" concept. A great concept, mind you, but out there.
I applaud the effort, and look forward to seeing when it is complete.

I'm looking at how low you're transfer case is hanging, Are you using the syty 4l80 adapter plate and the syty transfer case adapter? You need that to clock the transfer case in the correct position.

all parts are clocked as they would be on typhoon conversion.
I got a deal on a ls1 so I decided to build that up forged internals oringed heads etc, going twins instead of the tc76. I live in Minnesota the high today was -6 so progress has been slow. but still plan to have it on the road come spring.

Should be fine then.
That's while I'm in here bug, I've had mine finished at least 3 times.had the engine in and out at least 10 times!! LOL, I thought about twins but all my gas and oil plumbing is on the driver side, no room for a downpipe.Cool project, stay motivated!!
