so let me know what axles to run with my new 300zx diff!!!!


thanks guys.

300zx axels?
Not sure if they will fit..

But if they do,
there are plenty of high hp z's using stock axels.

[BadazzSr20]

i dont think they fit from what i read

[blessedhellrider]

z axles are too long.

not happening way to pricey im sure theres something i can use out there from a junk car? how is the r33 and the j30 how much can they hold upto?

[wangan_cruiser]

300zx na will fit. Just make sure they are both driver sides because passenger side is longer. Same goes with j30. I think oem axles will hold that much power

so ur thinking that the stock s14 axles will hold up on 650 to 700 lanuches at the track?

also i didnt no that i would need driver sides axles for both left and right on my car? i didnt hear about this till right now how for sure are u on these stayments?

the last guy i seen with s14 axles snaped them and he changed them at the track did a pass again and snaped it again. so i dont think stock axles will hold.

being that i cant get a straight answer from any forum i post on ill have to go with a common sense answer and shot for the r33s being that there coming off a skyline and we all know most skylines are 1000+ wheel.
unless i can get some straight proven answers from someone then i dont no what to go with.

if anyone has any info on some axles they ran or a friend that they seen run and not break please share.

thanks

I know this is incorrect on an S13, atleast. One side is "longer" than the other, it required the proper side to be installed for it to work.
Reference: Installed a 5 bolt 2way into my old vert and went to a junkyard and pulled 5 bolt shafts. When one side wouldnt fit, laid them next to eachother and saw the size difference. Used the other axle and it fit with no problem.

None of the factory axles are going to hold up to the power you're putting down. The first time you wheel hop they are going to twist off. Sorry to burst your bubble, but you need to upgrade from the factory glass CV joints. There are only a few options and they all require spending money, get use to it.

i find this really hard to belive when i see my friends useing a r33 stock axles with 490whp and had it for 5years no problems so far.i have been looking for some r33s but there hard to come by. im thinking to run with j30s for now till i can find something

anyone know what i can use beside the 2 i said that u can get for the junk yard not spend 1000 on it?

[jr_ss]

Q45 will hold more power than the J30/NA Z32/S-chassis axles. Regardless, they all have weak ass CVs and that's what snaps...

[slow92]

The Q45 diff with drivers side q45 axle and 300zx TT drivers side axle is going to be your best bet. They seem to be the strongest oem axles. This is the route I am going for my monster.

yeah i was going to do this too the problem is that you cant find this set up anywhere. so thats my im just doing this 300zx na diff with some axles till i can souce out the Q45 set up.

also with the Q45 set up i dont like that its 3.54 final gear so thats another reason why i havent made a big deal about getting them. i know theres a 3.69 final gear Q45 but again to find them is the problem. even if u find the diff the 300TT axles is a pain to find too were the 300zx diff na is the same final gear 4.01 as the stock open diff for the s14s.

then after you put your big drags on the car that 4.01 not drops to about a 3.90 and your in the same rang as a j30. also withs alot of that needs to be done to make the Q5 to work where the 300zx will just be a drop in so theres alot of ways you can go with this diffs

but back to the matter at hand im still in need of a axles that will hold some launches at 650 to 700whp? it can be done you see it all day long on youtube.

[slow92]

I understand your problem. I got lucky and my local pick and pull had a q45. I still need to get the z32 axle which it looks like I will have to buy a brand new one. I am not very excited about the gearing as well, but at the same time I don't want to spend over a 1k for some axles. Plus there is as a write up on here or Nico where a guy went through a couple of sets of mazworx's heavy duty axles and then went with the q45 setup and hasn't had any issues launching. You should check out the drag thread in the chat section. Santos makes almost 600whp and he is using a r32 diff but I don't know what axles he is using.

Good luck, wish I could be of more help.

[jr_ss]

Yeah, you see it on YouTube, but you don't know what axles get are running based in a launch or a run. Like I said, wheel hop is the enemy to stock axles. They are stout, but don't expect them to hold up long term. I have a set of the DSS axles for my car sitting on a shelf for that exact reason.

Your worried to much about the wheel hop if ur car doesn't spin u don't have wheel hop. For you to have wheel hop u need to break the tires loose. Launch the car right " witch means no spinning off the line" and u don't have to worrie about hoping.

Also there's more things i can do for wheel hop if u can't get your car to hook. sticky tires, lowering the car/altering suspension parts/bushings there's away around it I know IRS sucks and there really no way in the world to stop the wheel hop but what I just told u is a good start.

[jr_ss]

So what your saying is you don't do a burn out to heat your tires?

well this is a thread about axles not wheel hoping but ill answer this question and i would like to get back on topic cause i really need to know about my axles.

so yeah i burn out with street tires i do dry hoping for that no wheel hop at all.

for drags i use the water box i never wheel hopped on a burn out in my life not even with my front wheel drive car..

[slow92]

I am telling you, check out the drag zilvians thread in the chat area. This topic is being discussed right now and people are discussing there diff and axle setups.

[RTB.1054]

Don't thing any stock axles are going hold 650 -700whp but I used 300zx NA diff with 300zx NA axles and they fit just install both axles in first from the center of the car without disconnecting any arms then bolt axles to diff and raise it into place use a jack. The 300zx tt axles don't fit because they are to thick and don't fit into hubs unless you use 300zx tt knuckles/upright but not 100% sure .

As always, wheel hop will need to be limited. It's the destroyer of all things rear-end related. Seems to be more prone to happening with radials than full slicks.
I had a R32 Diff welded 4:36 gears with junkyard j30 5bolt axles.
I know of a LSx s13 that was ru ning low 6s in the 1/8th with a q45/Z32 set up spraying too made over 700

I'll have to check that out but in the mean time j30s is where it's at cause again them z32 axles and q45 axles isn't easy to come by. I guess I can start with j30s then I would like to try the r33 axles cause vying its a all wheel drive axle that has to be strong.

[slow92]

Ya that sounds like your best option right now. You can always change things later.
