Outer Limits 4x4 Board

I'm 18 and recently got my license and am driving a 1993 Nissan Terrano 2.7 Ltr Turbo Diesel Automatic!

This car has to be the biggest head screw ever as most of its engine parts are all Pathfinder parts and Navara Body or the other way around.

I wanted to know how much the Torsion bar on the car can be lifted without problems persisting in future?

Regards

Matt

My 2c:
2" is fine. Anything more will give you a crap drive as there is no negative suspension travel left and the CV boots will split all the time because of the steep angle.
Cheers

Thanks for that.
