Is a 3.92 lsd diff out of a xr4x4 a complete waste of time in a megablade, should i just hang on till i can find a 3.38?

I believe, the xr4x4 diff is 3.64. I use this with my zx9r and its fine. Its geared to do about 115 mph but that'll obviously be different with a blade engine.

XR 4x4 2.0L DOHC. Is a 3.9
XR 4x4 2.8 or 2.9 is a 3.6
I've got a 3.6 LSD and am open to serious offers

Yeah it was the v6 so it was the 3.6. I got it as my current is a non lsd and developing a fair bit of backlash, It was a bargain(ish) so i snapped it up. Should be fine i reckon, might loose a few mph top end over my 3.38 but better in the bends with it being a lsd. Anyone else running a 3.6 with a blade engine?

Yep I was till very recent
Unless your on 13's it may be a bit low , otherwise I think its the one to have . As said tops at 115, but crisp through the range

2.0l 4x4 is a 3.62

I ran a 3.62 on 185/60/13 tyres on my blade engine, it topped out at max revs on the flat with a good engine.

I doubt you will go any faster with a taller diff with this combo, just reduce the noise a bit

Fine for short circuits like Brands Indy, Lydden etc.
