So i found my vac leak, it was the oem metal t that is in the middle of the hose from the charge pipe to the wastegate. The one t that i thought would never fail since it was made out of metal blew apart.....crazy. Also found that one of the recirc valves was leaking so i swapped that out and she holds pressure now. I cleaned the turbo off and ill drive it around later to see exactly where its leaking from, Its not the feed line for sure and it really doesnt look like its coming from the return. It looks like its coming from the bottom of the compressor housing where its mated to the chra. Guess we will find out soon enough!

So while my truck is my next project (which shouldnt take more than a day or two), i need to figure out what turbos id like to go with. I have been tossing around the idea of running the jwt sport 500's and was really wondering what you guys would recommend. I like the price of the sport 500's but i think id get bored with them pretty quick. Anyone here running the disco taters and could give some recommendations?
Good news finding the leak, these cars can be a real PITA hunting down leaks such as you have and it's always good to have a path to search out.
As for snails, well as you mentioned I was also thinking sport 500's but when the time came, I was able to land a pair of JWT 530BB's with DP's that are just really nice. They claim a little more torque than many similarly-sized turbos and that is true, also they spool up really fast without a ton of mods- I have upgraded smics (Z1) and 800cc injectors/tune, turbo oiling kit, plus had my exhaust ports cleaned/enlarged slightly and use the DP's, but rest is stock exhaust to the back with larger mufflers and exits...point is it's not overly expensive to set up and the results were VERY good.
