the 89 maxima i have sitting in my yard rotting away has a crapped out vg30 in it, would it be possible to drop in a vg30dett directly in or would it take modification...im figuring its at least gonna be the same bottom end so the tranny should bolt right up correct? or am i jumping to conclusions? also there is the issue of the motor mounts and what the difference is between the 2 setups. has anyone done this or tried it? if so did it or will it work? thanks for the help.
