Dear Sirs,
Thanks for your answer.
Please note that both available engines is type 1MZE-FE, equal the damaged engine, but both has VVT-i, i.E. With continuously Variable -Valve Timing with intelligence.
The damaged engine does not have this VVT-i device.
I suppose that the electronic command of the car (computer) and its electrical installation are difference and the new motor could not function after installation. What about the different transmission speeds - five instead of four (existing) too?
By the way, could you inform me how can I confirm if the engine of a car has this system VVT-i, by checking the engine installation in the car?

Sorry I thought you had stated your faulty engine was WITH VVTi. Just noticed it states WITHOUT. You are quite correct the computer settings will be different. You could change the computers and associated wiring?. If you are not swapping the transmission it does not matter
