everything but the motor itself and even at that you'll have to drill and tap the front of the block for oil return off the turbo.
you will need wireing harness intake headers all accesories heater core throttle cable radiator etc...etc...

only real way to convert it to 86-87 setup is find a doner car with everything on it.
