in US u can watever things u want in supermarket. and the price also cheaper.
take for example the fuel injector cleaner stuff and tufoil. it is sold less than USD10. but in msia it is sold at RM60 for tufoil, fuel injector cleaner ranging from RM10-60.
in US they have all the machines to do every specific job. at here, i think we are superman larr. use 1 machine to do all jobs, can or not also hantam sahaja. somemore they using the old junk made in china manual machine to do the job. so how precise can the machine do the job? hehe.......... u know i know larr.......... u ask the boss to upgrade their machine to a better computerised and more precise machine they ask u goto hell cozs the cost of the machine is going to be maybe RM1M or more. but in US the machine is damm cheap. that is why people at there afford to build custom piston,custom crankshaft, custom camshaft, everything custom. at here usually we will goto chop shop to find the most appropriate things then send for grinding; then u see the use the old machine to grind it and the accuracy of the grinding is not 100% guarantee one. the machine operator is only know how to switch on and off the machine and set how many mm to grind it.
my friend wanted to DIY his car into NGV. so he bought all the things from india. then there is a block that he need to modify to fit into his engine. he send to the machine shop ask them to drill 2 hole through the block. the block is aluminium and its not so thick larr. about 1-2cm thick. so the shop did the job for RM50. when he take the block to his surprise! shit! they did drill the hole for him but the block wall is crack from the hole. and the shop boss say ur aluminium is damm soft and my drill bit is so hard. u see bro. stupid excuse! there are specific ways to handle specific task.
u see this discovery channel at astro. at US in a secondary school a group of students and a teacher manage to modify a car to run on ethanol and that car can do 0-100km/h is 6sec if not mistaken. and these students also make the ethanol fuel from corn!
in our country, i dont think there is a professor had done this or not. i admit that the secondary school lab is far more sophiscated and equip with many things compare to our U lab here.
