The obd II systems run around 50psi vs the earlier return systems that run around 42psi. At the end of the day, it's nothing major, but still a tweak that needs to be done.
I really do not know the compatibility between 1mz and 3vz stuff. I've not looked.  |
Great! thanks for the info. I will go back to my ebay items and double check that this is a 3vz rail. I just thought they were all the same but i am almost sure its a 3vz rail. I will also check old threads to see if anyone else knows about this 3vz rail. Thanks for the info. I will edit my listing to warn everyone else that this may not work.
