Diff

hi
I have looked around and couldnt find how power a TT diff can handle without beefing it up?
What have people done successfully?

 

Plenty, even the NA diff can take more punishment than 90% of people here can supply.

 

Just did some googling and couldn't find a single reference to a broken R230, if you're looking for a challenge you could see if you can be the first!

Getting a locker for one wont be as easy though and the visous lsd is really intended to help you out keeping it under control in the wet not do fat skids.

Edit: You can get lockers for the pathfinder R230, no idea how easy they fit in the Z or whether they will suit your needs.

 

More likely.....

.....to shear a drive axle than break the diff, although there have been occasional reports of the viscous centre failing during general usage/abuse.

There are four options:

1. Leave the diff stock.

2. Change to Leader Gears & lower the ratio to 4.1 (faster acceleration - less top speed).

3. Replace the viscous centre with a Quaife unit (geared centre, no parts to wear out such as clutch packs & warranty applies in racing applications).

4. Change to Leader Gears & a Quaife unit (the ultimate R230 diff).

 

ok. so they are as strong as hell but no good for skids. not what i wanteded to hear.

 

I have an R200 in my NA Z34 with 49/12 (4.08:1) gears and a KAAZ clutch-pack centre set stiff and with TCS and VDC off power sliding is simple.

I also have an R200 with 43/11 gears (3.9:1) with a Quaife and it is a whole lot softer in operation, but still able to provoke power slides in 1st and 2nd at will.

I also have the original OEM diff with viscous centre and it is not worth the money to take it to the tip. Acts like an open diff.

These diffs are pretty tough but if you are going for monster torque (500+ lbs/ft) then an R230 is the way to go - they are the equivalent of a Ford 9".

The drive shafts are the weakest link IMO

 

Weld it up. Plenty sick skids yo

 

Also Cusco. I think there are a couple more options as well.

 

Mechanical two ways are definitely better than the viscous but are they comparable to a locker for burnouts? It hasn't been mentioned in this thread but I'm assuming from his last that Aussie is looking for a diff for a burnout demo car.

 

If just for burnouts weld one up. Pretty cheap to pick one up to modify. Takes maybe an hour to swap them over when you want to do burnouts and then back again when you want it back to normal for street.
