don't turn up the boost until you get a large Front Mount Intercooler. Its just not good to pump more hot air into the motor than what stock boost (~7lbs) will be. Make sure you run it rich if you start cranking up the boost too. Do this with an SAFC, a wideband O2 sensor and most importantly a Dyno where someone knows how to set all that up properly! Don't go over 13-14psi boost on a T25 or T28 (dual BB or not). Thats about all that turbo can handle and still be reliable. Pay close attention to the gasket between the turbo and the exhaust manifold. If that motor sat for any length of time that will go very soon after you start cranking up boost. Use locking exhaust manifold nuts when you replace the gasket. I could go on forever...
