my friend has a OZ Edition Lancer with a 2 liter. It's a 2003 and he wants to know what engine it is and what its potential is. He would really like to start a turbo set up so we are trying to get info on whether any EVO kit would work. Any help would be awesome please...

I believe those came with the 4g69 engine.

If it is a Ralliart edition it came with the 2.4 liter 4g69 if it is the OZ edition with the 2.0 liter its a 4g94 or the 4g93 same block and as far as mods are concerned there are many mods out there for this car i myself have an 05 ES lancer which the only thing different is body and suspension and bolt pattern roadracemotorsports.com is great place to start starting with intake and exhaust good place to start

They also offer a nice turbo kit for the 2.0:D
