Lets take honda parts and slap them in our mitsus. They're both cars, it should work, right?

mivec only changes cam timing like an adjustable cam gear that moves all the time when driving when the ecu tells it to(half of honda's i-vtec, this was added to the original vtec when they went from b to k series engines), vtec actually locked rocker arms together at a certain rpm to switch to a totally different cam lobe(more aggressive) so you can obtain good power down low and switch to an almost race profile over 5,000 rpms. this is why b-series vtec cams cost considerably more than other types of cars, they have an extra lobe for each cylinder.

EDIT: After digging through the manual, I see the RA does control intake valve timing to a certain degree. Hope the formatting works...
Code:
Valve timing Intake valve Opens (BTDC) 10° <Low speed cam A> 12° <Low speed cam B> 24° <High speed cam> Closes (ABDC) 42° <Low speed cam A> 44° <Low speed cam B> 68° <High speed cam> Exhaust valve Opens (BBDC) 58° Closes (ATDC) 18°

so it controls intake and exhaust, and the different profiles in the cam modify timing? I think that is what this is saying. And I am not sure that it controls ignition timing. I think the degree measurements are the amount of lift the valves are getting. hence "valve timing" I am probably wrong on this part though, I am just putting something out there.

Nope, it doesn't control exhaust valves at all. The ECU controls ignition timing, this is only valve timing. The degrees listed are opening and closing of the valves. Yes, the lift changes, too. I should see if I can find the specs on valve lift.

Just to clear things up the only thing better that the US Lancer Ralliart have against the Evo (any evos) are your imaginations. Keep on dreaming guys.
