[CHA5ER]

Hey guys,

I have B04D diff in my jzx, and I find on the internet that it is torsen?!

But my car rejects to spin two wheels if I do clutch kick/ donut etc

How can I find out?

THanks

Pull the back cover off and have a look or research Torsen and follow instructions on how to jack car up and spin wheel to test.
From memory I think you need to hold tension in driveshaft as well otherwise will just spin opposite way like an open diff

Inspect or alternatively drop a wheel in gravel/grass/mud keep the other on the tarmac. Give it the beans. If the scenery doesn't change, somethings not right. Torsen only bias torque, they don't fully shift 100% of it from one wheel to the other. There's no initial bias as there's no preload. You sure its a Torsen, sounds like my MA70 clutch type..
