[QUOTE="evo5755, post: 3486673, member: 1644"] Thanks for the information explained for everyone knowledge. :biggrin: So you mentioned that with time, problem will occur to the spring and diaphragm of the actuator. the internal wastegate is made of spring inside and it controls the flap to release the exhaust gas on the turbo hotside. Whereas for external wastegate, it comprises of spring and diaphragm too, but with exhaust gas flowing through the external wastegate itself. So i think it will be very hot. If time goes by, if the problem occurs to the spring, does the external wastegate wear out way much faster than actuator because external wastegate has so much heat in it? Does this mean actuator is LESS reliable than external wastegate? Just to share on this point on why people opt to change external wastegate. Of course the biggest reason is sound and look for most people. :biggrin: But how about the actual functionality vs the orignial actuator? Bump: i am using turbosmart now. I know what is the advantage. It looks more cool, smaller, and lighter. :rofl: [/QUOTE]
