is the 1hz engine, gearbox and injector pump for land cruiser 75 series and land cruiser 79 the same or it has a diffrence. for a 79 series 1hz engine do i need gear box and injrctor pump for 79 series only or i can use for 75 series 1hz aswell?
 
The gearbox is different but interchangeable.
The fuel pump is much the same BUT the timing gear has an extra tooth , or maybe one less tooth I forget, so if you swap pumps you need to change the gear on the pump.
So your old pump would need to have the 79 series gear fitted to it. That's what a fuel injection specialist told me.
