Q45 diff w/s14 sub

hey guys,

Just looking to find out if what I'm about to purchase is what I need. Pretty sure I got it nailed down but doesn't hurt to check. So I'm steadily getting ready for my S14 sub frame swap and I'm picking up the last piece of the puzzle. Already have S14 sub, stance multilink everything, solid sub bushings, solid diff bushings, z32 rear hubs and brakes. I'm about ready to make my purchase for a Q45 diff I found for a decent price. Its from a 99 so it'll have the 3.69 rear end as opposed to the earlier 3.54 if I've done my research correctly. I also sourced down axles from a Q45 and a Z32TT to complete this. I guess my only question is will I be fine with the 3.69 rear or should I try to find the 3.54 rear? I'm already 11g deep into the engine which should be 500-550 hp (check my build thread). I'm probably going to pull the trigger on purchasing this diff tonight unless someone tells me otherwise.

Thanks
