Best IRS for a 92?

Hey guys I've got a couple questions bout this. Which IRS has the same bolt pattern as a toyota? Which one would be the best as far as set up and stuff? I'm wanting to build a new rear clip for my truck and put an IRS in it so I was wanting to know what to look for so I can call around.

i have an 88 mazda rx7 on my toyota. its the same bolt pattern.

Yeah the 88ish Rx-7 IRS is good for toyotas cuz its the same pattern, and it fits without having to narrow it.

Is the turbo one better?

Or whats the difference?

i think the turbo is 5 lug and the non turbo is 4lug. i think its something like that.... it could be the other way around.

Turbo is 5 lug

gen 2 series 4/5 whatever u call them i believe they come in an LSD and non LSD center could be wrong tho.
