ur gonna get ppl on here that say there junk. My experience with the obx LSD has been great. Set-up is LS/vtec turbo 619hp and 427 lb/tq. Never one problem with the tranny or LSd. Tranny is b16. I think u would like it.

People have had mixed reviews about them, some good, some bad. Its your tranny. Seems to be most people only have problems when trying to remove the axles. H-T sponcers sell the real version for 835 so why spend half and take a risk of damaging your tranny?

OBX has proven to be a great buy. They did have there issues early on but most or all are taken care of.

Plus, diff's like Quaife or OBX (torsen type) are almost fully incased and don't tend to spray metal bits all through your tranny. So in most cases a broken diff doesn't hurt your tranny.

Just ordered my OBX lsd, we'll see how it holds up. I ran some good times open diff but looking to make alot more power this year. The LSD is different for a gsr/itr and ls/b16.

I haven't heard good things with the Phantom Grip unit but the OBX we've used on a LS trans and it works fine.

I have never seen a diff. in times with a LSD.. B16-LS-Type-R all use the same diff. and the GSR is a diff unit. I have a Qauife in my car now and I wouldnt go half assed on a LSD.

Just be sure to take the OBX aprt and check it. I've found metal bits inside and
loose bolts holding it together.

Also just grind a 45 degree angle on the snap rings that hold the axle in place. This way they will come out agein. If you don't good luck..

Thats what I plan on doing, tearing it all down, cleaning it all, and putting it back together with proper torque specs. The new OBX diffs already fixed the problem with the stuck axles.

It really kinda easy, Phanton Grip is well, junk, OBX is a knock off of a good diff.

Torsen and Quaife are not the same. Quaife is a helical gear. One difference will be 2.5:1 bias v. 4.5:1 bias. The Quaife almost guarantees traction during split traction events due to the amount of gears that are required to rotate in so many different axis. A torsen will wear in such that on a split, you can still do a 1-legger.

Quaife has a lifetime warranty even when raced so if you break it they fix it period (except in a talon cause our 3rd gear is known to explode ruining the diff lol) and you go back racing for nuthin. OBX may hold up but it's not warrantied lifetime and it's also not a Torque Biasing differential. Torsen tries to lock up, Quaife put the power to the wheel with grip being able to send almost 100% of the power to the outside wheel where torsen can't achieve anywhere near that.

Really their beauty is in road course and on the street not in drag. They will achieve a full lock up, my GTi always smoked both wheels even with the tires turned hard to one side.

In the end you get what you pay for. Dont cheap out on Tires, Brakes, Clutches or your Tranny. Everything else can be done cheapy and pretty well not matter.

Remember the rule...

GOOD FAST CHEAP, you can pick only two.
fast and cheap isn't good
good and cheap isn't fast
good and fast isn't cheap
