Hey everyone, working on finishing a swap on a early model 240sx, 5.3 with a 76mm turbo, and a 4L80e. I have the ability to grab up a couple different rear ends, 3.35, 3.53, 3.69, and a 4.08 haven't selected a converter yet, just researching my options first. We're pushing for 600 out of the 5.3 and tire size on a daily basis with be 235/45/17 lol. Any help or opinions would be greatly appreciated.

Thank you
