After alot of research n ideas of diff choices i have decided to go for a borg warner diff for my lc as the standard banjo aint goin to last long.i want to get a 4 pinion 28 spline lsd which came in vl turbos and sum v8s, what i want to know is wot else these came in i understand that r31, and some falcons and i think centuras had 78 series bw are they 25 or 28 spline. If so are they interchangable as in can i get a pintara centre 4.11 or skyline 3.9 and put it in a vl diff etc. i was intially goin to get a minispool but i have decided to get a detroit style locker as this is a street car and i dont want it too be locked all the time, i found that 4wd systems sell the LOKKA diff locker which is similar to detroit locker for the BW, people on the vl forum have also mentioned the lockright by richmond gears but i cant find any listings for the BW on ther site, or any aust suppliers. Also do detroit lockers make a locker for the 28 spline BW, the only listing i found was for a non irs 3.08 bw diff which wud b out of a vn i think.any help or ideas would be appreciated thanx.

my honest opinion is that the B/W is an ecconomic, light weight, 4 pinion,LSD - disk brake equipt alternative to a 9".
if you going to spend deviating from this route the go the 9".

Better save up if you're interested in a Detroit Locker for a B-W... i have a modified VL Turbo setup in my LX hatch and was quoted around $1500 for the Detroit centre alone! LSD's are a much cheaper, and legal approach...

the LOKKA from the 4wd shop is only $599 and is the same thing as a detroit locker, and i thought it is only spools that are illegal cause they are locked all the time

sorry im not familliar with these diffs. do they lock left or right or both, same as detroit.the LOKKA from the 4wd shop is only $599 and is the same thing as a detroit locker, and i thought it is only spools that are illegal cause they are locked all the time
it is illegal to run a diff with both rear wheels locked, not sure if one left of one right counts. still be pretty dangerous on the street eh?

The BW seems to have the name given to it unfairly. Maybe it is because the companies that do diff conversion charge the same amount and very one knows the 9" diffs are strong... well i personally would nto run a 9" as they are actually weak. there is alot of work to make them strong as they have inherant flaws, infact there are alot of people out there runnign s 9" diff which actually have 8 3/4" gears in them so not really a true 9" anyway.my honest opinion is that the B/W is an ecconomic, light weight, 4 pinion,LSD - disk brake equipt alternative to a 9".
if you going to spend deviating from this route the go the 9".
The unfortunate thing with modifying things is that yes it is labour intensive and as such if you need to do the same mods to get teh length right then the cost are going to come out similar. I can tell you know that I am in the process of shortening a BW for my Eh and so far it has cost me approx $50 plus a little for teh diff to start with. I plan to have this in the car and runnign for under $500. Not the $1500 I was quoted. Shop around and see what can be picked up. LSd are easy to come by. My advise would be to get an open centre first and buiold it that way when a lsd centre comes along it is a drop in replacment. 4 pinion lsds came in all VN onwards v8s. Ie what I mean by thsi is if the car was a v8 and a lsd it was the 4 pinion. So happy hunting...
Cheers

all vn iupwards diffs are 4 pin and the same diff.there is no difference from a v6-v8 diff.not all v8 diffs are lsd either. if anyone one wants an lsd centre i have one here that can be swapped for alcholic beverages

with the lokka diff it is not locked 24/7, so if you do a sharp turn the left wheel will not chirp like a minispool would, but as soon as you plant ur foot and the wheel is goin to break traction it locks and spins at the same speed as the right wheel. With this fitted i heard you need to change your driving style, and it can be a bit unpredictable cause it can jus lock up. This product is australian designed intially for 4wheel drives but they recently released ones for the 9 " and BW, 4wd systems sell them.

i am assuning that any of these lockers can be put into any diff ie. open or lsd. If this is the case could i buy a standard vl open wheel diff 25 spline have all the work down to it and fit the 28 spline locker and custom made 28 spline axles would that work cause then it will b easy to get a diff or do i have to have a 28 spline diff from the begginig for this to work.

Easier way would be the 28 spline to begin with. You are not worthwhile starting with a LSD and going to a locker as you would need to find an open centre...
Cheers
PS: If you get a VL diff and cut it down you will probably find that there will be no spline left on the axles anyway so starting with a 25 spline axle and resplining it to a 28 will not be an issue.

i thing you are better off starting off with the lokka and finding a diff to suite it.
the operation from your description sounds more the same as a LSD than a detroit
