Which one is better and why are there so many?
I note that with my 92 na6 long nose crank, it's an 'open' diff but if there's going to be extra grunt added, what's the deal with the other available diffs?
i remember viscous LSD of my good ol and ancient '90 Pulsar Q LOL
can someone explain please....

1) standard 6" 4.3:1 open diff
2) OEM viscous 6" diff - these are known to wear out though, so are probably ineffective at this age
3) Aftermarket centres for the 6" diff (KAAZ, CIG locker, spool, etc)
The 6" ring and pinion are quite weak and can break even with OEM power levels.
4) 7" 4.1:1 diff from a NA8 - this upgrade involves retrofitting the tailshaft and driveshafts also.
5) OEM TorSen version of the above. Type I and Type II Torsens are available from different years. This is probably the best option for a road car.
6) similar centres as per 3, but with more options (eg Guru, RX-7 clutch pack). Also more gear ratio options. (3.6, 3.9, 4.1, 4.3, 4.44, 4.57, 5.?). Best choice for racing.
The 7" R&P is much stronger.

Thanks, great breakdown...
So, an OEM TorSen is the way to go? what're the differences in the type 1 and 2?
