am saving money for engine transplant now. :Dwell... although u mentioned that you dont wanna change convert engine, but i really advise u do so cos tiara engine is from citroen, and no more spare parts from proton anymore, my dad's frend used to own one, whenever he needs replacement part, he will then slashed by the chop shop... by a doing an engine transplant, u can have more power, cheaper maintainence, better fc... y not?
