Looks like you already decided on the Q45 rear but I wanted to throw in my 2 cents worth. I totally agree with the others here. I had the stock 4.08 rear in mine and it pretty much made the T56 useless in 1st unless you wanted to do an insane burn out. With the 3.54 Q rearend it is much more friendly to drive. Plus as you probably know you get the 30 spline axles and bigger hubs plus VLSD. My motor make 530hp and gets abused pretty heavily and so far its hanging in there.

most 4x4 actually have a frame that you can weld or bolt something to and might absorb some impacts, there's only sheet metal in front of the si14, I just wished the oil pan was a little higher that way i could lower the car with no worries, there's plenty of spacing between oil pan and ground so it's no issue going over speed bumps, i not too much worried about any rocks hitting it just bottoming out

I sent you a link with the full Nissan service manual. Should help you figure it all out. I totally removed my under hood fuse / relay center and installed my own in the passenger side air bag location. It cleans up the engine bay and I removed a ton of extra and unnecessary wiring. I then built my own front end harness for the ligths, horn, etc. and a second one just for the engine / trans.

I know that if you send the inside and outside harness of the 240sx and the ls1 harness, sikky can make it work for a price and i think hinson can too.
There is just so many extra wires that are not needed with the stock ls1 harness, the painless harness to me just make the install so much cleaner and easier.

IMO they handle great after the swap. There really isn't that big of a weight difference between the Iron block 4 cylinder and the Aluminum LS1.
Oh and another bonus to the 3.54 Q45 rear end is if you happen to daily drive this thing, 75 mph on the highway is around 1900 rpms.
