Keep up the good work! This cold weather sure is nasty... can't wait to see it done!

 

um its actually bad to run a syty without a front drive shaft. you should be ok with the axle disconnect and the driveshaft in though.

 

Nice build...
Transfer case is a little to low, but if you protect it, it sould not be a problem.

240sx with LS1 awd...

Actually with the front axle disconected you will smoke the T case in a matter of minutes. You have to have the awd working all the time or it will grenade itself. Change to an astro van one piece left axle and eliminate the switch. or change to a auto 4wd T case that you can lock or unlock at will. Even then it will be harsh locked up. No give in the clutch pack. G

 

Actually, it's the right (passenger's side) axle shaft that is the single piece / 2piece assembly. And the Bravada single piece shaft is probably easier to find, they're pretty plentiful (any year Bravada has that shaft).

Do yourself a favor and just don't run this in 2wd. The viscous coupling in the BW 4472 doesn't appreciate it. Yes, you can get away with this for some amount of time, but its a matter of time before you completely cook the VC and it remains locked all the time. When that happens, the vehicle will no longer be AWD, it'll be 4wd high (no longer any differential action front to rear) and it'll try to hop tires around corners. Check on SyTy.net if you don't believe me. BTW, a replacement VC is in the neighborhood of $500 to $600, so it's not the most expensive oops, but not cheap either.

The "On-Demand" transfer cases (like the NV136 or 246) could be made to work (with a bunch of effort), but I know you've got a bunch of money invested in the existing setup, which will work just fine for a really long time if you don't try to run in 2wd.

Also, be warned that if you run it in 2wd (either with no front propshaft or the axle disconnect) use the parking brake or wheel chocks. Without resistance on both shafts of the Tcase (front and rear outputs), the VC will allow the vehicle to slowly move. Some Sy / Ty / Bravada / Astro owners have been very suprised when they removed the front shaft, parked somewhere, and the vehicle wasn't were they left it when they returned. Typically doesn't move fast enough to do damage, but you never know. One of the SyTy guy's recently related that he parked in the driveway with no front shaft. And figured out he had a problem from all the honking horns from the road out front. His truck was in the middle of the street, just sitting there. Didn't hit anything, but certainly could have done something stupid.

Otherwise, keep wrenchin' away on the project. And stay warm!

wow not only your putting ls motor but your converting it AWD..you r just plain sick...very creative.... how about subbie ls?

 

lol! I,m dumb and dislexic. I meant the passengers side obviously the left doesn't split.

 

Wow, very ambitious project. Love it!

 

jesus, Thats a bad *** project. any updates?

 

WOW!!! props on this build. i like strange builds like this. that car is gunna be a monster.

 

i would loose the bm ratchet shifter in a heartbeat and install a compushift tranny controller and a twist mashine steeringwheel paddleshifter.. have one in my Bu and its awesome... that way you can have a toggle to change between full auto, and full manual driving....

Project looks good so far.

looked through this a little bit, and from what i saw you didnt have front wheel clutches, as an awd would have. maybe i missed it, or just cant read right.

but thats one of the major differences from awd and 4wd, and if you dont and it is 4wd. then its going to suck.

another thing is, that the weight transfer in this beast is crazy amount of up front death.



its and awesome looking project cant wait to see it done.

 

wtf is a front wheel clutch? The difference between a 4wd and awd is pretty much all in the t-case. what is up front death?

 

Awesome, subscribing

 

you know, if you don't clutch your front death then bad things happen to your awd4wd splitter ring dig?
