I would stay away from the 3.0 V6, things a dog, I have one in my 4runner If you want to do the Toyota V6 use the 3.4 out of the Tacomas. Just my opinion...
Id turbo charge the 22re or if you really want a Toyota v6 then get the 3.4 out if a Tacoma!! Hell you can always be like those crazy Australian guys & go with a Lexus or Supra motor swap!
