Check out the link above to my Complete Reference. There is a post today, I linked where Magnuson basically says it wasn’t necessary. The OP accidentally stripped off part of the coating and Magnuson explained the purpose of the coating. So probably no. My intent for this build is to keep boost on the conservative side.
I like the B16! I’ve toyed with the idea of engine swapping it. Maybe one day. For now supercharging is where my interest lies. But as with most mods- it’s lead to many sub projects like replacing the alternator, AC Compressor, doing a timing belt replacement, completely overhauling my AC system lol. Eventually I will get the JRSC done but since I’ve gotten everything a part now, it’s the best time to replace old parts right?
