zthis Posted November 5, 2004 Share Posted November 5, 2004 Is it possible swap a gear set (3.90) from a ZX into a 1975 R200. Other than changing tire height are there any other cheap ways to increase the gear ratio from 3.54 to 3.9 or higher ? Quote Link to comment Share on other sites More sharing options...
Mike C Posted November 11, 2004 Share Posted November 11, 2004 Why swap gears when you can swap the whole center? Gears can be done, but ideally you should have a pinion depth checker to make sure everything is spot on. Quote Link to comment Share on other sites More sharing options...

Mike C Posted November 13, 2004 Share Posted November 13, 2004 Sure. Same way that the 1st GEN 300ZX LSD center can be swapped. The only thing that might need to be changed is the pinion yoke. I currently have an 85 300ZX 3.54 geared 12mm R200 in my car. I had to change the square yoke to the round one for crossmember clearance. Other than that, everything else is the same. If you get it from a CV equipped car, you will need the stub axles from the 1st gen R200. Quote Link to comment Share on other sites More sharing options...
