My 7AFE turboed, suggestions on what i should do Options

[ArizonaRed]

I just recently added a turbo kit into my 7AFE. Added a T25 turbo, downpipe, manifold, map box, oil regulator, blow off valve, intake. The downpipe had to be welded and my alternator and fuse box had to be moved. I have an oil leak that I cant tell where its coming from, maybe the oil return line. There is no power increase, the engine idles up and down on its own while in park and neutral. I drive the car at least 300 miles every weekend and usually lose about a quart of oil. When i accelerate it will sometimes push forward and sometimes resist and not boost. I think my car has less power with the mods on it than it did before. I thought my breaks were going out but it turned out to be that oil was all over them from the leak. Anybody got suggestions on this frankenstein car? The people down here in Georgia dont know anything about my car. The Toyota dealership mechanics and custom shops cant help. I have no smoke coming from the engine. The engine has 109000 on it. im using automatic trans. If anybody is in GA, theyre welcome to look at it. It was dynoed and results were bare bones.
