I'm under the impression that a 83 nissan 4x4 rear end will fit my 280zxt .Also that my car has 3.54 rear end in it .The truck is suppose to have a 3.90 rear end in it .Right? Will this give my automatic car better take off? Will the axles from my car bolt up.

thank jason(280zxt)

I ,M PROBABLY NOT QUALIFIED TO ANSWER THIS BECAUSE I'VE NEVER HAD A TURBO.BUT SOME GUYS AT THE THE DRAG STRIP RUNNIN TURBOS TOLD ME THAT THEIR CARS RAN BETTER WITH NUMERICALLY LOWER RATIOS.THEY SAID IF YOU WERE GEARED TO LOW THE CAR REVVED TO QUICKLY AND DIDNT GIVE THE TURBO TIME TO LOAD UP AND BUILD BOOST.I DON'T KNOW I THEY ARE RIGHT BUT I DO KNOW YOU WOULDNT LIKE THE HIGHER REVS ON INTERSTATE, SINCE I THINK TURBO AUTO DOESNT HAVE OVERDRIVE.

I was under the impression that a nissan 4x4 pickup had a solid axle rear end instead on independent suspension like Z's I just used a 3.9 out of an 82 280zx direct bolt up.

Jason,
You want to find a 81-83 ZX non-turbo, manual tranny, due to differences in axles as already posted. These cars have the 3.90.

You need to read the LSD Diff article in the Winter 1996 Z Car Magazine. It says that the 83 4x4 is an R-180 with 3.9 gears and will fit Z's. But if you currently have an R-200 you will need to get some parts for the conversion including the moustache bar and possibly the half-shafts and driveshaft from a Z with an R-180.
