I wonder if its possable to do a head swap from the 04 lancer with the MIVEC onto the 01-03 lancers. Which problems would i have or can i just get the MIVEC without doing a head swap. For those that dont know what MIVEC is, Its exactly like V-Tec(HONDA).

 

do you have one to do that with or are you just curious?

 

well if it aint such a head ache i would like to do it.

 

yah i wanna know if its possible let me know if u do it hehe

 

You'll also need the ECU from a MIVEC powered car since the non-MIVEC ECUs obviously won't know what's going on with the two cams.

 

You can't. They are two completely different engines. The '04 MIVEC from the Ralliart is a 4G69 engine, essentially a bored out, naturally aspirated version of the Evo's engine. The non-Ralliart Lancers all use 4G94 engines. The 9-series is a completely different engine from the 6-series.

And the Ralliart engine a single-cam engine... MIVEC doesn't necessarily mean it has two cams, just two cam profiles. The Evo's engine is DOHC, but the Ralliart is still only SOHC.

how about old eclipse engine? or newest eclipse gs rs?

 

The old Eclipses used the same engine types as the current Evo and Ralliart. The new ones, I have no idea, but I'm guessing you're still gonna be out of luck. There have been a few threads about getting a better head for our Lancers, and I think in Thailand they made a few 4G93 DOHC engines, but they are so hard to come by, especially just to get the head and ECU, that it's unrealistic to get one here. And still, that's not MIVEC, just DOHC.

Sorry, that's what I meant, two profiles for the cam to follow, not two cams.

 

To further expand, I doubt either stock ECU would run the car reliably. The variations in displacement and therefore likely also fuel mapping would probably cause serious issues. IMO, if you have your heart set on a MIVEC engine, take the whole thing. And if you're so interested in that you'd probably be better trading in your non-MIVEC for a Ralliart. Just my $0.02.
