CV & Halfshaft Axle Upgrades

[AceInHole]

For some reason I can't buy a new RH axle, and my axles are pretty shot. Because of this, I'd like to upgrade. Ideally, I'd like to run 300zx TT wheel bearings and hubs, along with 300zx TT axles. Do these have the same bolt pattern on the diff side as the NA axles (I've got the NA z32 stubs already)?

Also, I've seen some ads claim the S13 and S14 passenger side axle to be the same. Can anyone confirm this?

The z32 TT uses a different flange for the axle, doesn't it? And the splines into the hub are bigger (and won't work).

The flange side is what I'm concerned with. Like I said, I already have 300zx NA flanges for the diff. I can use z32TT outer hubs for the larger splines. It'd give me a larger bearing, which I'm hoping will translate into more durability.

Looks like the J30 axles are pretty close to the S14. I might pick up a pair of those for now since my current CVs are pretty shot.

i have two Q45 rear hubs, that bolt right on and the splines are 2mm bigger than 300zx, 240sx splines. just saying

Yeah, I think the Q45 is the same size as the Z32 TT bearing/spline on the wheel side of things. But it's longer I think...?

I'm almost positive the inner flange to the differential is the same bolt patter from NA to TT. I have a stash of parts at a buddy's house, I can take some measurements if needed.

Not to be anal about this but neither the S-chassis or Z32's, etc use CV joints to my knowledge. I believe they all use 3 roller tripod joints on both ends of the 1/2 axles. A real 5-ball CV joint would be an upgrade but a larger tripod joint would help as well. Has anyone pulled the boots on the Z32 or J series 1/2 axles to compare?

It would be great if you could confirm the bolt patterns being compatible between the TT and NA axles. I'm a confirmation away from buying parts

^ bingo theres the info.

Basically

Q45/Z32TT hubs, Q45 LH axle as rh 240sx axle, Z32TT LH axle as 240sx LH axle.

Q45 diff assembly ( *should*) be able to swap on J30 or whichever other R&P to get the gear ratio back where you want it.

Maybe look into doing a full ford 8.8 swap if u wanna be baller? I about did this....

I've heard the Ford diffs are heavy, even the aluminum case Cobra ones. The R200 is honestly so overbuilt for the power levels anybody is running on this forum that I don't think I'd bother.

If you've got 5 bolt output shafts, J30 axles are quite a bit stronger than S13 stuff at a small weight penalty.

Could the same be said about the 6-bolt J30 axles?

orly? What about an LS2 swap pushing at about 500hp and 450-470ish ft/lbs? R200 isn't that strong iirc? I think it's claimed the R230 can handle that kinda power, no?

Yes, I just threw in a set not to long ago.

There are plenty of KA-Ts pushing more power than that with short gears and slicks.

You won't break an R200 from rolling on the power - the axles will give out before that. Slicks put a huge strain on it, but it's generally the stoutest part of the drivetrain.

All the 600-700 rwhp S chassis run R200s. Plus if you munch one (doubt it), they're dirt cheap.
