So your injecting water before the impellers? I know TRD is injecting before the impellers but I thought Eaton didn't recommend it do to the impellers pitting or someting along those lines...

I actually thought so at first too and disagreed with Gadget that the motors did in fact have a harmonic balancer. With a bit more research (an a quick call to an engineer friend of mine who works at toyota) I found out that the harmnic balancer on the front is actually just a pulley with a rubber ring to dampen the shock on the ascessories. Both the 3.0 and the 3.4 are in fact both internally balanced motors.....this is why the engines are so bullet-proof and they run for 200-300k before a rebuild.

Just wanted to clear up any confusion for people who find this post.
