Making an XJ into a rally car?

Teal,

I :worship: to your superior knowledge of performance tuning, but...

The NP242 uses planetary gears!
No viscuous couplings, no clutches.

I guess the article i read was mistake, i just looked some more, it is a planatary for full and part time, and an open diff for full time, i dont know for sure how its locked for part time or low, maybe that is the clutch they were refering to

At least the three I have rebuilt haven't had Viscuous couplings or clutches

planetary all the way.

That being said. I have rebuilt three. They are not the worlds strongest.

ive rebuilt a few myself....none of which failed due to abuse, they just plain wore out.
 
Ive herd and seen that if your going to have issues w/your sway-bar then you can put steering stablizers in place of your swaybar end links.

It seems to be becoming more common. I've seen three different setups all involving short stabilizer 'shocks' used in place of the swaybar links. In all three cases though, it was to allow movement of the swaybar in fast-paced offroad usage. In a road-based cherokee, especially for racing, I would imagine the stock-style setup with a stronger anti-sway bar would be preferable to the shock setup...
 
If you are going to add a turbo, you are already changing your class. I would at least swap out the front for an Independent setup. This will also save you some weight. Could probably just use some Liberty parts and box the control arms for stength.
 
I'll sell you my 91 240sx. That would be an alsome rally car fun fast and rwd get a good tire, shocks, set up and cage it on the road you go. I would do a car if I was in your shoe's and mostly because of the low COG. But it would look cool as hell to see some one rally in a xj. You would be the only one I know of using an xj so the cool factor is there. and just to let you no I was in to the rice seen "imports" not to long ago I'm not saying I no it all but I do no what I'm talking about when it comes to that. when I wanted to get an good 4x4, I started looking at jeep I was sold and just like there is this alsome club "naxja" to help you with your jeep there is also countless clubs to help you with 240sx, and you can find out alot about 240s and just about any other car out there. but what do I know im just a newbee....


ps. your not totally wacked. just creative.

I think anyone that uses this set-up doesn't know enough about vehicle dynamics to be touching anything. Sway-bars are used to tune the roll moments front and rear to help or reduce the over/understeer effect. They also help body roll, but they add spring rate to the system. A shock doesn't have any spring rate.

I agree with everything there. How does that disprove what I have seen?
