i agree with phjat7.
its like us spending rm15k to convert a NA to turbo engine, complete with suspension and other bits included. laser cut, painted etc. for the same price in m'sia, i don't think you'll be able to get a kit of that sort. which i'im sure the co would have done their R&D bit to ensure reliability and what not. good thing in the states, the co can be sued until their underwear if the customer is not happy or their product is fukekd.
but in m'sia, if the engine goes boom after 30 minutes from the workshop, majority of time the mech takes no responsibility. which woudl u prefer?
