97 tacoma race truck build

Hey everyone! I am new to this forum and am hoping to get some good info from all you taco enthusiasts out there. I am planning a race truck build for my 97 tacoma rwd. I will be putting a 2jz twin turbo in it with the 6spd tranny, lowering it with a race suspension set up, widening the fenders for wider wheels, caging it with bucket seats and 5 point harnesses, and also some frame modifications for rigidity.

Im really excited about this build and looking forward to starting it but i am still in the research and development stages.

A couple of my questions are what is available for a 4 link coilover rear suspension conversion and what rear end would be best to use (as far as fitment and performance)?

I have found a couple suspension packages but none of them were a race set up. I also was thinking possibly about a nissan r200 rear diff out of a 300zx.

Any thoughts, suggestions, or helpful tips would be greatly appreciated. Thanks!
