Q45 diff upgrade

[tiale11]

Hi all. I am new to this forum but have been around Z32 stuff for sometime now.
I have an idea regarding nissan/infinity differentials that i am trying to see if its feasible but cannot find enough information online to sway me in a direction for my Z32 TT.

To summarize...
1)I have A LOT of power and will brake my current r200 5 bolt axles if i try to put it down. so i want 6 bolt flanges/axles
2) My car Z32TT will be used mostly for road racing with a Kaaz 1.5
3) i am not going with Z32 TT subframe with the r230 diff and 6 bolt axles because the only gear that's available for it is 3.69 and that way too low for (yes i have driven on it before as i had a 300zx with it).
4) i am not going with a 350Z case because it has different mounting locations
5) i WANT to go with a pre-96 Q45 with the 6 bolts but i cannot find any aftermarket lsd like kaaz for it. so i thought maybe putting in a kaaz made for a 350z would fit in a q45 case nicely as the seem to be very similar. <--- NEED input on this please
6) i would really like to go with a 3.9 gear ratio in the rear (both 350Z and J30 offer that)...

So, how do you guys put aftermarket LSD in your cars while maintaining the 6 bolt flanges?
thanks,
-Alex

Thanks a lot for the links Lino. One of the things i learned is that the R32 GTR CLSD can be transferred over to the g50 Q45 with little fuss. with that in mind, instead of sourcing a R32 diff, i can just get an aftermaket LSD for the R32 and just get a g50 Q45 diff to fit it in no? i guess it will end up looking like something like this

i am unsure about the use of spacers yet but ill look into that when i get the chance.
