front sump
front oilpump pickup
original 'front' mount engine mounts off the 5m in the car
ecu and loom
7m fuel pump resitor and relay (5m uses the afm to do this)
it all bolts in with zero required modification
and theres only 2 (maybe 3?) small loom plugs which need to be mated to the body loom.
7mge has a cpacity increase under 15% over the 2.8L 5m, but power is over the 15% increase required by the rta for engineering purposes. its also JUST over a 15% increase over the 5mge (what a pain) - but if you convince the lowly rta types that our cars came fitted with a 6m, say, in japan (200hp) you MIGHT get awat with not engineering it...
i, rather biased-ly, think the 7mge is a great motor, and think that the swap is well worth it if you like the thoughts of playing with a hi-per na powerplant...
