The thing is for most people here, the stock internals with factory cams will do everything they will every need it to do. Theres really not a huge amount of work needed for a 2JZGTE to be ready to get a 240z into the 9's power wise. In that case, they are very affordable.
Beyond the longblock, you will need the following:
Exhaust manifold
Turbo sized for the power you want to make
3"+ Downpipe and exhaust
oil feed and return lines
air filter
boost tubes, clamps, and couplers
intercooler
properly sized fuel pump, injectors, and lines, regulator, and rail.
Its really all of the sub systems that cost the most money, not the motor itself.
