Hi all,
I've seen lots of people talking about wastegate actuator which can be an important issue to a turbocharger. So far, I know one thing is A Big Turbo + Small Engine with Big power need Bigger Actuator...
So my question is If I bought a turbo without actuator and I need to get one from somewhere apparently, so how to properly choose a wastegate actuator for a turbocharger? For example, GT28RS, GT3071X, TN450 and TN500? What actuator should I use for those turbos, especially for TN series turbos because they sometimes are not including actuator when you buy a TN series turbo?

Cheers
