Yeah kind of agree with LS2 hatch, if your going to the lengths of fitting an LS.
Id say no to banjo in any form with that motor.

+2c from me too, $1000 won't quite buy you a converted 9" but it's better to put it toward something stronger rather than tear it up the first time you "do a Grant" and side-step the clutch @ 5000 RPM!

 

If money's tight you can always buy the converted 9" housing and axles but just throw an el'cheapo one-wheeler centre from a wrecking yard in for now, then play with gearing and 'limiting the slip' later when all the other bills are out of the way? So long as the axle spline count is correct of course.

 

As much as I hate to recommend a ford product, the 9" is basically "industry standard" these days, you could convert something like a Chevy 12-bolt but they're a lot harder to find parts for second-hand. Strange Engineering also do a banjo-style carrier for a 12-bolt centre but it fits into a 9" housing anyway so I don't really see the point?

 

The only saving grace is... you can actually build a complete 9" diff these days without actually using any ford parts, so is it technically still a ford diff? (That's my argument anyway and I'm sticking by it)

Haha, agreed. People have been using Ford 9" parts in Holdens now for such a long time, that it's actually become a tradition in itself. If you're not in on it, you're missing out. Not to mention the sheer common sense of it too, superior upgrade and universal readily available parts.

B/w commo diff if want to keep the weight down & rear disc conversion.Crewman diff if want something even stronger if anti-ford & something little bit lighter.

 

Had b/w in lc gtr no issues abusing that although got 9" in tubbed commodore....although heavy feels practically unbreakable

9 inch is a big centre to fit into an LJ, i would kind of side with a borg warner with a kaaz LSD.
If you think you will want more power later, be honest with yourself, then go 9 inch.
They are 9inch by name only now, nothing ford about them, such a large aftermarket industry supplying them.

Spend the money once. I have nine inch setups in both my LJ coupes. Trouble free to date. Plenty of space to fit one in.
Piss easy to change the centre yourself if you want to try a different ratio.
