yeah you have to modify the rear subframe to fit the z diff, but why? there are other cars with diffs that bolt right into a 240 without modification and you get the correct final drive too. but if you do modify to fit you can use the factory z axels because they are the correct length and spline count.fireslave wrote:Ok, so no-one i know of has used the 350z diff for this swap... i happen to have one and was wondering if it would be possible to put it in...
the subframe would have to be modified, but thats not a huge deal... the huge deal is the axles. the short axle from the 350z is about the right length to be used as the long axle for my s13, but i still need a shorter axle...
the shorter axle has to be about 1 3/8ths inches shorter than the 350z's short axle, or about 2 3/4ths inches shorter than the 350zs long axle...
anyone know if there are any nissan axles out there that i could use for this application?
otherwise im gonna have to use a different diff, or spend bills on a custom axle...
I also heard that the g35 has a skinnier track than the 350z.... does this mean it has shorter halfshafts? and by how much?
use aftermarket links and lower control arm to widen the stance so you don't have to modify the half shafts.fireslave wrote:my axles seem to be about 1 3/8th inches too long per side...(i have an s13)

OK GANG, are you ready for this?! I took a few measurements at work today.
**if you are doing the 350Z swap into your S13, and you dont want to mess with the shifter and driveshaft problem....just use a 6-speed trans and drive shaft from the 05 and newer X-Terra. Why, cause it will all fit perfectly. Yeap, all the measurements show this to be the exact lengths you need, all the way down to where the shifter pops up through the car! Good stuff huh?
The only fab needed at that point will be the flange from the X-Terra diff will be needed or reflange the driveshaft from the X-Terra with the 240 flange. Thats it.
Man, its wicked how this stuff works.
X-Terra Drive Shaft --- one piece alluminum.
Later all!

SpecDRacing wrote:Good news for the budget swaps out there. I recently purchased a set of extremely inexpensive headers from Rade Design Imports (http://www.racedesignimports.com) for my Sentra VQ35DE swap. Now, they aren't stillen or JWT quality, but will work great for what I am trying to accomplish. I'm betting they will have some available for the rear wheel drive VQ35DE soon. Check them out. The owner has been great in helping me and actually responds to emails (unlike most Ebay sellers). Sorry to throw this plug in here, but considering the price and good customer service, I feel they need to be mentioned.
