Or hit up ebay seller duax_machine as he usually has one or one on the way. He's out of texas iirc. I picked up one from him a couple years ago, and he's still an active ebayer.

This is what I did when I bought my S15 Helical, I think I paid just over $500 and it was at my door step in 5 working days from Japan. Just put it on your tab at Harry's

therein lies the problem. you have to trust that they got the correct ouput shafts with the diff when it was pulled from the car. most of these importers dont know shit about what theyre importing and dont actually pull the parts themselves. if the output shafts dont work, then youre stuck with a diff that is useless until you can source the proper S15 output shafts, and if you havent noticed, those arent exactly the easiest of things to come by.

the OBX unit works with open diff shafts which makes life for damn near all of us S13 owners a lot easier!

e1_griego · 02-27-2014, 02:55 PM

I've never gotten one with the wrong output shafts. And duax_machine knows exactly what's up regarding the s15 diffs.

If you're using paypal and ebay, you shouldn't have an issue.

Drivetrain parts from OBX just doesn't sit well with me. If you want to do that, do it, but it's within spitting distance in price for OEM stuff.

The Dude · 02-27-2014, 03:51 PM

I rolled the dice and bought one of these probably about 2 years ago. Took the shitty washers out and replaced them with non-broken ones, did a little deburring, and also some thread chasing was necessary. So far so good. However, I paid quite a bit less than what I'm seeing them going for now. I would buy S15 helical unless you can get a good deal on an OBX unit and you aren't scared to rebuild it and make your own shims.

You can't put 29 spline shafts in the helical anyway, and there's nothing to strip. Some people choose to buy the 13mm shank nismo ring gear bolts but you can just reuse the oem 12mm ring gear bolts and it's fine. I've done three different diffs with the stock ring gear bolts and never had a problem.

I am also resusing the oem 12mm ring gear bolts. Went in just fine. that was almost a year 30k+ miles ago, not a single issue.

***dorkidori_s13*** · 02-27-2014, 06:58 PM

i reused my OEM ring gear bolts when i put my ATS 2 Way in my first 240. ran around on them for almost 100k miles with zero problems. just gotta make sure you re-coat them bad boys with loctite!

The fact this site exists should say to everyone nix the obx and get an S15 HLSD if you want a torsen diff.

Have you drifted on it?

I really can't find solid non-fanboy reports of how it does drifting. I'm a 2 events a year kinda guy, not a pro am wannabe.

My welded is driving me nuts with the tire eating and highway death wobbles.

I'm also not keen on dropping $1,400 for a clutch type.

You ought to hit up Mike at THmotorsports for an ATS clutch type. He hooked me up with a brand new one shipped straight from Japan next day air for a price that you wouldn't pass up. Comes with new seals and bearings/ races too. ATS is the shit.

e1_griego · 07-23-2015, 12:10 AM

Giken is the answer.

Corbic, arne't you posting in the DIW thread all the time yet you're rocking a welded diff?

Tsk tsk.

I have a Carbonetic Carbon in an s14 pumpkin that I'm willing to part with.

it ran with me thru probably a good 20-30 events in its life time while i had it. locked up just as tight when i sold it with my last 240 (#4) in 2009 as the day i put it in my first 240 in 2004.

as far as drifting goes on a helical diff, mine worked just dandy on saturday when i took the girl im seeing out drifting for the first time. it didnt push quite as hard as a clutch style diff, but it did just fine! i wouldnt trade it for the world

theyre not quite as bad as they seem. took some friends of mine here in town about 2 1/2 years to nuke the one in their track only 10 second EG civic hatch.

though i would highly recommend quaife over OBX any day. the quaife torsen diff is damn near the same thing as the S15 helical, but it works with OE 6 bolt open diff shafts as well as OE 5 bolt shafts too.

Balls of Steel bro.

It's actually not as bad as people make it out to be. Not much different then a locked spool. The only issues is tire wear and instability over 65mph on anything on than than marble streets.

DIW would be rocking the open or trying to JB Weld the open ^_~

e1_griego · 07-23-2015, 09:59 AM

I've driven 2 welded diffs in my 10 years and some change of screwing with 240s and I hated both. A lot.

I pray at the altar of OSG.
