what frank has pointed out is true, can not be to naive on conversion. Cause basically the halfcut is already a second hand item, you wouldn't know whether the previous owner take care of the engine or not.
moreover, internal part is unseen. like my case, engine can start, cantik cantik. But hell, after the conversion, so many problems until i can spend on another halfcut.
moral of the story, do a survey, check if the mech is realiable on TURBO ENGINE, do HOMEWORK on engine that u wish to install at least. Don't rush it cause some lobang good and cheap might come by.
lastly, prepare some spare cash at least i think on ur case 3K for some replacement parts, maybe some minor upgrades.
