How much would shipping from new zealand be?
an rb30, complete below the head gasket can be picked up for $63 nz, about $40us. plus an hour to remove it from the car.
There is also a pretty big supply of them.
If enough people were interested, and sorted out the best way to ship, i could lay my hands on enough motors for around 200-250nzd, drained, cleaned, and wrapped in rags and plastic
