Bro, I have been able to find the manual for the 1KzTe engine.. but not the complete repair manual for the Prado. I am looking still. Will update you by eve.
UPDATE: Ok, i have got the repair manuals, more focused on electricals but including mechanicals of the 1KZ-TE and and one about the body of 90 series Prado as well. Along with the TLC 1998-2007 Manuals. Data around 100Mb. If you need, let me know how to transfer.
