hey guys i had installed a redtop SR20det engline in my AE and the damn thing broke 2 rear diffs already! one was a welded diff (not so important) the other was a 10 bolt LSD diff (a few blades from the pinion went missing :/).
Now i'm thinking about installing a silvia LSD (S13 preferably coz it's 4 bolts and cheaper) now has any1 done this before? i've been looking all over the internet for a writeup on this but i cant find anything usefull! plz help me out here guys. tell me what is the basic process and the necessary parts and whether the Silvia suspension will be straight bolt-on or does it need some custom fabrication to make it fit?? I NEED HELP

Lots of fabrication required
You have to cut out the the rear frame of the GTS and weld or bolt in the Nissan subframe

Best I can find to help you.
Did you look into a MA46/47 rear end? That might be an easier, stronger option for you...
