R200V Z32 Non Turbo swap

[1993_570ZX]

Hey guys, im swapping an LT1 into a 1993 Z32 2+2. From my research about the car, It has a R200V with a 4.09 gear, 5 bolt flanges.

 

I dont care for the 4.09 ratio and would like to bring it lower. would like to be able to drive on the highway

I know I can take the entire setup from a Twin Turbo, and swap to a R230, but still have a 3.70 gear. (Better but still high for my taste)

 

I looked around and seems that Q45s have a short R200V as well. Here's my questions about the Q45 rear ends and what would work.

 

What ratio was in these? Ive found that the 89-96 is a 3.545 ratio 6 bolt flange.

also found that the 97-01 were a 3.69 ratio and 5 bolt flange.

 

what ratio was in the newer ones? (trying to clear up some possible misinformation, found it both ways in posts)(hoping its 3.54 and 5 bolt to direct swap)

 

to be able to straight swap this into my Z32 NA, can i just use a 5 bolt rear and just swap pumpkin, using my shafts?

if the newer q45 rear has a 3.69 ratio, and i still want the 3.54, can i use the 6 bolt rear end and swap my axles to TT axles(6 bolt)
