well, for me as a carbie user,i think if its properly tuned, can whack turbo cars too ;) just like our very own unker fred ;) he also got DCOE's marr...can eat turbo wan lehh :P ahahaha, JK JK, well, about consumption, its all in the tuning ;) properly tune it and it will be running for a very very long time, no need alwiz tune wan, unless your hand itchy wanna try something else lorr, then mar alwiz play tune tune tune ;) my opinion lar tho, cause i think if the engine never give you problem no poiunt to transplant new one also, cause later you transplant new one, then maybe the new engine got problem also, need to overhaul and all, so its like, no mattter what, if engine still can jalan, use until cannot jalan lorr....butthen dun purposely go rosak the engine larr so that you got excuse to transplant it :P akkaakak
