About the engine
After making some research I found that the engine in the European Yaris RS is 1.8-liter
(2ZR-FE) dual VVT-i



and the engine in the Toyota Corolla 2008 1.8-liter (2ZR-FAE) dual VVT-i




So I thinkthey are similar little bit just I didn't understand what is the difference between the corolla (2ZR-FAE) and yaris (2ZR-FE) both of them are Toyota ZR engine,, they are from the same ZR engine family.

I found this from wikipedia under (http://en.wikipedia.org/wiki/Toyota_ZR_engine).

this is the only difference I found about the engine

about the gearbox
My yaris has 4 speed automatic gearbox I think it is the U340E usually they use this kind of transmission in Yaris since 2006

about the manual gearbox the Yaris 1.3L has the C551A 5-Speed Manual Transmission and some has C54A 5-Speed Manual Transmission but the first one is more popular.
For more info about Toyota transmissions this is the List of Toyota transmissions http://en.wikipedia.org/wiki/List_of..._transmissions


About the Engine Control Unit -ECU
If I use the Corolla (2ZR-FAE) engine of course I will use Corolla ECU usually it comes with engine or you can ask supplier for it

In the end If I want to use the Corolla (2ZR-FAE) engine for my Yaris I have to use Corolla gearbox and Corolla ECU this is what I end up with why I want to use Corolla (2ZR-FAE) engine because in my region we don't have Yaris with 1.8L only we have 1.3 and 1.5, and I found the similar engine for the yaris 1.8 is Corolla (2ZR-FAE) engine it is the same just little different it will not make that big problem.

The only big problem am worried about and am sure about it, is the axles I think it will make me big headache, if someome can help me tell me

The FAE has some upgrades to produce slightly better fuel economy. 10.5:1 compression versus 10.1:1 for the FE and the FAE has the valvematic system along with the dual VVTI.
