i want to do manual conversion on 5VZ-FE 2 wheel drive

what parts do i need? which box? also do i need cert afterwards?

also is there a way to do 4wd conversion from 2wd?

i can tell you an auto to manual will not require cert as the parts are from the same family of vehicles.

how ever, 2wd to 4wd would be easier by buying a 4wd chassis and putting your 2wd cab on it.
