Estimated prices?

I have a 2007 toyota tacoma pre-runner crew cab, I am willing to put the money and time to convert it to a 4wd however Can someone tell me exactly everything I need to purchase to convert itand and estimated price if you could I'd appreciate it

 

cheaper to just buy a 4x4

 

X2 , lots of threads on this and ultimately this is the conclusion in all of them.

 

I just have alot of value in my taco and i cant get rid of it its like my child

 

What you mean value? Like mods? If so then take it off and make it stock again if you have those stock items. Trade it in for a new 4x4

You value your taco like your own child..... Changing it from 4x2 to 4x4 is like changing your daughter to a boy x.x Both are expensive and better choice is to get a new one. 50/50 on the boy tho XD
