Finnaly Full Booost!!!!
well after about 4 months of endless leak testing and sealing, and more leaking testing, i have FINNALY got full boost. Turns out it was the wastegate not functioning properly and leaking boost that was the big issue. After reading through Homemadeturbo.com i found an interesting idea that i followed up on. It involved removing the wastegate and using a carberator spring from the wastegate arm and attaching to to the block or where ever gave decent tension. I installed the spring last night, sealed up the BOV a litte bit, and waited for my drive to work today to see how it would work. Well turns out it worked like a charm
The best part is the spring opens at EXACTLY 10 psi, which is right where i wanted to be. Full boost feels amazing, and i cant wait to go get tuned now. Air fuel actually looks pretty good, but my timing is still really conservative. Ill be hoping to get to a dyno in the next few weeks and find out my numbers and get her running perfect

WOO-HOO!!! Finally. Glad you got it sorted out, man!
Before you throw out the idea of using a wastegate actuator, remember that the spring gives slightly at lower boost pressures. You should try to get a replacement wastegate actuator that will keep the wastegate completely closed until your desired boost pressure is achieved. Your spool time will be a tad quicker like that. Test the wastegate actuator with a bicycle pump and see if it works before you throw it out.
Just cause of the honky that I am, here's the Mitsubishi part numbers for a new 14b wastegate actuator. You can order them from Rockville Mitsubishi cheaper than anyone else around, and you can find their info on-line at www.mitsupartsdirect.com. Sean, Will, and Mike are awesome, they've come through for me a million times getting weird or hard to get parts.

Oh well. The info is there for anyone else that needs it. External gates are much more manageable, and you'll be way happier with a different manifold. The biggest problem with used turbos is that people usually remove them for a reason. I bet you've learned more about forced induction while troubleshooting this than you really wanted to.
Care to come down to Richmond Dragway next spring? Friday Night Street Shootout usually yields lots of passes for $15. I might have my Colt finished by then if I'm lucky.
