So I just finished my motor setup (rods, pistons, 264 cams, springs, ras, gt2871r .64, 740cc, enthalpy tune, greddy im, etc...) and I am tired of the boost creep. After doing some research it looks as though external is the way to fix my issues. So basically I need to weld on a flange (planned on welding to stock manifold, but where exactly?), get a wastegate (planning on tial 38mm), weld the flap shut in the turbo (more details anyone?) and then I'm good to go. I also have a quwsetion about the springs in the wastegate. I plan on running 19-20 psi. If I use say a 15psi spring and set my EBC to 20 will I get creep issues again? Will I basically be limited to the boost the springs are set at? To recap, here's my questions...

-Good wastegates for my setup?
-Where to weld flange on stock manifold?
-How to weld flapper shut on turbo?
-Springs, EBC's, boost...huh?

Thanks.
