Bhai go for the swap, no worries. Yahan pe mark II mein 2JZ GTE lag jata hai aur aam corolla mein 4AGE to ismein kia problem hai. I would, however suggest you to go for either 1.6 engine of se saloon or 1.8 of altis. Thus you would enjoy it to the most. Ask karakoram, he has mates in shobha who can do it for you very easily and consult him about the same. If you decide to sell it, I assure you that you wouldn't get the price you are expecting even in dera ismail khan region where diesel cars are still an asset.
