05 Lancer ES engine swap

I'm Looking to change my stock SOHC engine to a DOHC Engine. What Engine shoud I Use that would fit in my car?

4G63 is the only one I can think of, will cost around $5000 though.

what the engine or the whole conversion???? is it true that they are hard to find??? my cousin wants a 4g63 too

you can find 4g63's on e-bay. pretty much all over the net. take a couple hours and look for the best price though. good luck
