need to know!!!!

I am currently planning on either putting a celica gts engine or a 3sgte into my MR-S, the swap on the celica engine would be about $5000, but i was woundering what would the price on a 3sgte swap including labor, would be. It is possible, apex did it. 500 hp would be amazing in the
mr-s. If 200 hp to the wheels gives the mr-s power enough to bust out with 12.6 1/4 time slips what would 500 hp do?
Can any of u tech heads even guestimate how much it would cost?
