Kraken G25-550 turbo questions
 

Hello everyone, I recently got my kraken turbo kit in and I had a few questions about stuff on the turbo. It's a .72ar t25 IWG turbo, so the IWG stuff is mainly what I wanted to ask some questions about.

Here's my questions:

1. What size hose should I need to fit onto the wasgate nipple?
2. Where can I buy a 90° fitting for my wastegate boost source? Im not quite sure what id look up to find it
3. How do I set IWG preload, and how should I know if it's too much or too little?

I'll provide some pictures of the turbo below

The little hex head near the compressor is where my wastegate boost source would go, but im not sure what size thread it is, im assuming a 1/8\" NPT.

Same question about the nipple size on the wastegate, jm assuming 1/8\".

You run a vacuum line from the coldside IC pipe to the wastegate. You leave the port on the turbo closed.
