Questions Installing Q45 Diff - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Gjohnson7 · 06-07-2009, 12:42 PM

Ok, I have S14 with an open Diff and I am in the process of swapping in a Q45 Diff. I've already pulled it out and swapped the covers. I have the driverside Q45 half shaft, but I am running into problems sourcing the 90 - 96 300zx TT driverside halfshaft. I've checked at the local parts stores and Autozone which usually has them says their vendor is out of stock and they have no idea if they will ever be restocked.

I might have found them at another local parts shop, but I have to know if there is a difference between the Auto and Manual half shafts on the 300zx TT. I wouldn't imagine there is, but then again the must be a reason for them asking. Any ideas, or other suggestions.

Thanks, but I'm not really sure how that helps. It's basiclly the same info I already had about my swap.

'90-94 Q45 Need different axles AND hubs - You'll need: (per Steve of S&M Racing)
'90-94 Q45 (or Z32 turbo) rear hubs (5-lug)
2 new axles: One from a turbo Z32, one from a Q45
PASS. side of your S13/S14 uses a DRIVERS side Q45 axle
DRIVERS side of your S13/S14 uses a DRIVERS side Z32 TT axle
Input/pinion flange is LARGER - Need a different driveshaft or flange.

My problem is finding the Z32 TT axle. Called Nissan today and they don't have it either. I might have found 1 on Car-parts.com. If I don't have any other options.

what's the reason for using a Q45 diff?

reelyfast · 06-08-2009, 07:38 PM

then just go get a 95 or 96 J30 diff.... it bolts right up and will be easier for you in the end. might even cost you less money than what you're trying to do right now.

Gjohnson7 · 06-08-2009, 08:03 PM

Well, I think I found 1 on Car-parts.com in TN that I will be picking up.
Thanks anyways.

I thought about the J30, but I want the lower gearing of the Q45 and I allready have the Diff, Uprights, 5 lug hubs and the Q45 axel. Just needing the 300zx TT.
