for the 4g64 block to evo head, you can use the factory evo timing belt, but its really tight. then degree the cams to the crank with the adjustable gears (appx.-4*/-4*).
the water pump is the biggest issue imo.
most companies provide an "adapter plate" (errr plasma cut sheetmetal) that doesnt work very well. basically the block water passage on the 4g64 is larger than the evo h2o pump housing. so, i fastened the pump housing down on my welding bench and welded more aluminum in this area of the pump housing to create a larger "flange" and cover the exposed water passage. then using a silicone injected paper gasket material, made a custom gasket.
works like a charm.
i can tell you from experience that the "adapters" don't work very well. i can change the water pump on our car in about 45 min now lol

edit: as far as the 00-03 eclipse, i think the issue is the actual block casting(engine mount, ac mount, ps mounts) being different, not sure though.
i do know that the Lancer rally art model 2.4L mivec sohc block works perfect.
