How do you know what waste gate to get? I am a turbo newb. I have no idea what determines what waste gate should be used.
I am still in the turbo selection process and don't have anything concrete yet on what I will get, but it will be "around" the size of an 88mm turbo pushing upwards of around 24#'s of boost at its max. Looking for 1,000 at the tire.
I have heard lots of guys say that they have had issues with upping the boost, or having the boost bleed off. I am guessing this is due to improper springs in their wastegate. But again, I am a newb, and want to learn so that once I have the right wastegate picked out, I won't have to deal with these issues later.
I don't know if it matters, but I plan on running an eBoost2 controller.
A little on a second topic: How do you know what BOV to run? I was going to run a Tial 50mm BOV, but someone said that may not be enough for what I am going to be running? Any advice here also?

How would I know if the Tial wasn't enough? Its very loud, so I know it moves a TON of air. Is there some way of calculating what I need? I just don't want to run into issues during my build.
Anyone else have any info?

Placement is more important the smaller you go. The higher the boost you run, a smaller the wastegate can be used, the lower boost you run on a big turbo, the bigger wastegate you're gonna need to keep the boost creep down. I'd spring for two 44mm, but I bet you could get away with well placed 38mm gates.
