Hey guys,
I hope this isn't coming off as a shameless plug (because it essentially is), but I've been a member of the NICO forums for a long while (7+ years), so I feel like I've paid my dues enough to plug my articles (if any moderator disagrees, feel free to delete this post). I'll be posting on here periodically with links to articles I have written on turbocharging in general (I myself have a smog-legal KA-T with 343 rwhp, so for those of you who don't know me, I've been there and done that!).
I think the articles are really informative and are a great place to start if you're new to turbocharging, and now when anyone searches on the KA-T forum about choosing a manifold or wastegate, this post will come up with informative links that will hopefully answer questions that would otherwise become new posts.
Anyway, here are the links. And again, if you disagree with anything or think something's just plain wrong (I'm writing my articles based on knowledge I've picked up along the way, so some of the stuff might be wrong or contentious, and of course I make plenty of mistakes).
