Which G series LSD?

[TTV8RA23]

Hey guys the time has come or getting very close anyway for me to sort out a diff head for the RA23. Its running Hilux G series 8" Diff head. I compared a hilux head to my mates diff head out of his MX83 which he had swapped JZX internals into and i reckon with a bit of clever machining ill be able to bolt it in.
My next question is, which is the better LSD to use? Its gonna be a 90% street driven car but i do not want it to single spin EVER!! Need something nice and strong too thats gonna live up to the power and preferably nice and smooth. The two options i have been looking at so far are a second hand JZX90 head, and a brand new Detroit truetrac. Im quite confident the JZ diff would be up to the task but is this gonna give me the zero slip under power that i want? Also is the truetrac as good a diff and is it likely to handlethe power? The only ones i have seen are for Hilux setups and hilux are not the most powerful of beasts so was just wondering about that.
Also are there any other types of LSD that can be fitted to a g series diff that like Kazz etc that others could suggest?? I was just gonna run a spool but i think that will be silly on a predominantly street car!
Cheers any opinions appreciated.

I have one of these:

Performance Products | Detroit Truetrac Differentials

I am really happy with it and how it works. But I am not putting much power through it though.

I would ideally like to get one of these too but i am not sure how it would go handling the torque. Im not saying i think they are weak i just havent heard any reports of toughness.

Have a look around a few of the 4x4 forums. There are quite a few people around with bogan V8's, V6's (including blown), and toyota turboed 6 powered hilux's that run the detroit true track LSD's instead of full lockers. If they can withstand the shock loading from going from loose mud to rock to mud repetively, they can't be too bad.

That said, there isn't that much wrong with the standard hilux (similar to the cressida / supra etc) LSD. . . . Once they are spring'd and shim'd they are tight, reliable and quite easy to live with. The biggest draw back is the fact that they need to be adjusted periodically to maintain their performance.
In my hilux, I had (both) the springs replaced with new toyota ones, and shimmed it up tight a few years ago, and its still going strong. I've never played with the one in my MA71 though, and it still spins both.
There was a thread on here not long ago and someone was making up stiffer springs for the G series in a cressida, maybe search for it?

Anything more than about 250hp smokes the clutches and shims in hilux diffs real quick from the rebuilds i have seen done. I thought clutch pack is no good with lots of torque and grip? Mechanical gear type torsen/trutrac is what i need i think. I have done a bit of research on the trutrac and it sounds like the 9 inch ones are well made and handle big power in big heavy yank tank things running 9 second quarters on transbraked Auto. So surely the 8 inch version for G series should handle what load ill be putting through it with the little celica.
Anyone know if they always twin spin under power? Even throwing hard one way and unloading inside tyre a fair bit? This is something i cant find.

i have a jzx100 with 311kw, and 700nm torque using one of these diffs, definately up to anythin i can throw at it
its a very tight diff tho and can be annoyin at low speeds always carrying the inside wheel
