I agree, but the $600 you mention would be $600 US, which is a bit more here [about $800] None the less, it's still the best overall compromise you can use.

The problem with welded lockers is the total lack of lateral [sideways] traction when you give it a bootfull in a bend in the wet & spin up both wheels. Thats when the rear swaps ends with the front,... & if you collide with another car on the street because of that, the cops will give you grief & the insurance company will try to wipe you like a dirty ars*hole.
Thats when you discover just how expensive a welded locker can be.

oh that's why, it's a bit too good ;)

but perfect for drifting ;0

I initially ran a welded diff in my S13 for drifting and it does the job but it's still not as good as the proper 2-way LSD I fitted later. The LSD gave more control through transitions and made the car more predictable. It was easier on the driveshafts too!

I ran a locked diff in my 510. It's great for drag racing but that's about all. It actually drives pretty well on the street but you have to treat it with respect in the wet. I don't think I'd ever recommend it. When my SR goes in I'm fitting an LSD with it. Car's with IRS like the 510 can get away with an open diff up to reasonable power levels I find but live axle cars are just plain annoying, spinning the inside wheel out of corners. To a degree running lots of roll resistance up front with a soft rear setup helps a bit but I think for anything with a bit of go an LSD is essential.

The only car I've had with a locker is my AMC Javelin. It's really very agricultural

was the blubird trx diff an LSD? that was my first car and I had an lsd in that but dont know if it was std if it is an lsd it would be a great cheap conversion and would come with the bonus of rear disks

There is no mention of an LSD in my 910 Bluebird parts book, so it was not even offered as an option.
As far as I can tell, none of these Bluebirds ever left the showroom floor in a retail sale with an LSD. [unless specially ordered & custom fitted by the dealer, assuming that they would know how to get one.]

I don't think that the H165 diff was ever available with an LSD as a standard or optional offering in Australia.

I have a mini spool in my R31 diff. Permantly locked. I have no dramas with it. Don't have to worry about a LSD wearing either.

go the lsd..

worth every penny

If you want to keep it a Nissan product, look into a late model Pathfinder LSD. They seem to be common and inexpensive (at least here in the States).

You'll probably have to use the entire rear axle, and it will probably be overkill, which is always a good thing for dragracing.

another option - if you can find one is the Borg warner 88

yes there IS a BW88 diff! it was developed for R/T E55 Valiant chargers...

how strong is an escort rs2000 diff they would be a pretty close fit for a 1200
