The 4G63 has come in a variaty of cars but in the Evo it is in a unique design then others and hence the Evo 4G63 engines are very expensive. In the UAE the price starts from AED12,000= 200,000 Pak Rps that is just the engine only and if you want the tranny with the Transfer case you are looking at a Cool 400,000 Pak rps. And expect to pay more for anything extra you want from the Evo, like ecu, or harness.
I do have one extra but not for sale 
BTW, why unique coz it has the tranny on the left hand side rather then the right side as it comes in all the other cars. You Cna get a 4G63 from a Eclipse for about 40,000 rps if you are lucky.
But, why do you want an Evo engine for?
