S13, Q45 axle upgrade help please!!

[cubantunr]

Ok to start off ive searched and read quiet a bit but still some unanswered questions..
i know i need the 90-96 q45 and 300zx tt driver side axles but here is were i got questions..
1. can i use my original pumkin diff from my s13 hatch?? i dont like the idea of vsld. and mines already welded
2. do i need to modify/cut the axles in anyway if so how?
3. i already have 5 lug conversion hubs for the rear will the axles fit right in??

i guess im trying to keep as much of my drivetrain as possible while still being able to maintain 500-600hp
any help would be appreciated thanks.

first off, you will have to use the vlsd from the q45 because the output shafts are a larger spline as well as the guts and is required to use the larger axles.
Second YOU DO NOT NEED TO CUT OR MODIFY AXLES OR OUTPUT SHAFTS ..... EVEN WITH A HYBRID SETUP!.
Third, the axles will not fit in your 5 lug hubs, you will HAVE to use the q45 or z32tt 5 lug hubs.... That's the only way.

Thanks! And do I need the q45 knuckles or does it all bolt up to s13 knuckles

The hubs bolt up to the s13 knuckles no problem but if you get the knuckles keep them in case you ever decide to use an upright strut.
