Hello, I have a 94 3vze motor out of a 94 4runner that I'm rebuilding and am planning to put it in my 91 4runner after I pull its 3vze out. Is there anything I should know when doing this? I plan on putting the 91's motor in the 94 later on..I am assuming this will all work..is there anything I should be on the lookout for or have to modifiy?? I seen somthing extra attached on the 94's fuel rail..thanks
