RB20DET swap with 280zx 3.9 diff?


Recommended Posts

Potentially looking to swap in an rb20det and reading up on some forums.  I come across a lot of posts not mentioning rear diffs when swapping them in.  Will I be ok with my 3.9 r200 from an 82zx?  Should I LSD swap it?  Also, will the stock 1978 280z driveshaft be ok to keep?  From what I've read, it looks like it'll be fine if I use stock RB mounts with the 280z tranny mount.

The only thing i can really answer for you is the Diff question. That Diff will be plenty strong but you will be doing 1 wheel burnouts until you put some sort of LSD in it. I run Quaife LSD and love it. There are other makes out there that people like too.

Good luck with the swap!!
