2 liter 16 valve DOHC turbocharged 4-cyl engine built by mitsubishisee also: quickly; eclipse; vr-4 The worlds greatest & most quickly modyfiable engine. A robust but terrible motor "built" by Mitsubishi. To finish the fued involving the 3sgte plus the 4g63, The 3sgte performed come ahead of the 4g63, which mitsubishi replicated in energy but not dependability. 3rd gen 3sgte developed 255hp on 7psi while the 4g63 creates 300hp on 18psi. A tremendously unreliable motor that most likely strike before you pay that EVO down.
