hi mate i have a evo 5 which i have owned for 15 months now which was pretty much standard when i bought it, since then i had full 3" exhaust, apexi induction kit, evo 8 ecu, walbro fuel pump, Apexi AVC-R boost controller, paddle clutch now running 1.5 bar and it's never missed a beat and was used as a every day car untill recently.

awsome car easy to tune but they do eat the petrol but when you look that they run 560cc injectors standard your not surprised,

Evo 4's suffer from crankwalk witch was cured from the 5's onwards also they smaller injectors and ECU cannot be mapped as well so most change for evo 5, 6 ecu with bigger injectors so if i was you i would get the best evo 5 or 6 you can

here's mine
