Yesterday i picked up a "JDM s14 vlsd" today i posted to try and find some info and i see pictures of a j30 diff they look exactly the same. Now either i got ripped or there's something fishy.

Here are some pictures if anyone is able to identify it, looks exactly like a j30 to me only thing is that i haven't seen the rear cover to a j30 so that is what is leaving me confused

it looks like the 14 rear cover but it says 93 so it might be j30

Got any pics of the internals? I have a j30 in mine and I probably have pics of it somewhere for comparison.

Not really i am not trying to take it apart, do the diff covers look the same as the j30. Even if it was a j30 i would not want it, because the reason i got it was because the gear ratio is the same

Anyone know?

That is an early J30, the 5bolt output shafts and finned cover give it away. Later J30s look just like the S14 diff, 6bolt with a flat cover.

My question is, how did you get ripped off? It's the same exact unit as an S14 VLSD, which is the same in Japan or the US. In fact, the larger cover has both increased cooling and oil capacity, both of which you wouldn't get from any S14 diff. Only the later J30t models have a different gear ratio, that's a 4.08:1 just like your OE diff and any S14 diff would be. Plus you get the benefit of buying a diff that's been gently driven in an automatic luxury car it's whole life instead of beaten to death from sliding into guardrails and ditches from a JDM car. Aside from needing 5bolt axles I don't see any problem here, other than the seller not being honest.

very well said, and if you want to keep the same axles as you have currently you can obtain the output shafts with the same flange thats needed for the stock s chassis axles, or you can just get 2 brand new j30 axles from the parts store and give them your s chassis axles as a core, pay cash and they will never know the difference when you bring your axles in. Most of the parts stores will give you a lifetime warrenty on them anyways.

Just do make sure to change the fluid in that thing before using it.
