MazdaComp sells a Torsen unit, but I'm not sure on price. I know it's a bit salty, though. Your better bet would be to find someone parting out a GSL from the same year as your car and buy the rear end. That way you don't have to worry about changing driveshafts or brakelines...

A Gleason TorSen unit isn't a Limited SLip - it's a 'no-slip'. It mechanically sends the torque to the wheel with the most traction, whereas a limited slip allows some slippage before essentially connecting the two axles into a solid one and sending equal toque to both wheels irrespective of traction.

TorSens can be expensive, but it's definately a case of 'you get what you pay for'

Viscous coupling, I believe - using fluid to allow a certain slip before lockup

You will definatly pay for a Torsen rear end but it is the way to go if you are looking for performance. If you are drag racing(dumping the clutch) you will destroy this unit! If you are autocrossing, roadracing, or looking for nice cornering go with the Torsen.....Mazdaspeed Developement, Guru, or a Miata Torsen unit. If you are drag racing stick with the viscous type.....just build up the stock unit with some oversized discs. in it.............my $.02.

Check out the the guys at Guru Motorsport $795 plus about $40 for the fedex to the US.

www.gururmotorsports.com
Actually I think Gforce in the states and mazdatrix is starting to sell them, but you can still buy them direct.

The product offering is heaps stronger and better set-up than a normal "torsen", i.e. when you lift a wheel Torsens tend not to bite, the TBD from Guru does.

This is along similar lines, how else can the GSL rear end be upgraded? Bigger axles? if so where can you get them? What else can be done to improve it?

Shame on you manntis! Viscous couplings are generally used in AWD cars, acting as a center differential to help prevent the front differential from being locked to the rear differential when driving. They're NOT used in the GSL rear. The GSL differential is a clutched limited slip differential, no more, no less.

I stand corrected.

Mazdaspeed also makes an LSD for the first gen and it seems to still be available believe it or not. I wish this picture was bigger but you can still see clearly "SA22C" as when of the applications:



Unfortunatly I can't tell if it's 1, 1.5, or 2 way....
