I recently installed the aristo 2jz engine into my 93 Supra. I installed an 96 us harness with ECU. I Still have the factory Aristo o2 sensor 3-wire. Do I need to buy an Us 2jz o2 sensor? or can I use the aristo one?

So you spend the money to do the swap but dont want to buy a new o2 sensor? Chances are the aristo one is messed up.

Not what I'm asking, money is not the issue. I just need to know- what the differences are between the two!

use the aristo 02 sensor!! if it is bad then buy another make sure it's not a four wire sensor if you buy new one , won't work trust me!!!!!!!!!!!
