On race gas, it'll have no problem making over 600. This is assuming that's the GT40 with the 56trim 61mm compressor wheel and a GT40 exhaust wheel?
Either way, good luck with your project.
p.s.: My car was a daily driven street car

BTW, I never suggested your previous car was not a street car...
I I have specific goals for my car, this project has been well thought out, well planned, and pre-designed...My number 1 goal is not top HP at the upper limits, but quickness of the car on the lower end... 
It is indeed a Garrett GT40 throughout, with the exception of the Precision outer turbine housing, I think you can see that in the above pics...

Level 2 and 3 will cost significantly more money than Level 1, and it will include details such as changing out stock internals to forged ones, changes to exhaust design, engine management, and such.

Oh yeah, I have to install the Premier/MB Quart/JL/Alpine V12 Stereo system-Still in the box waiting installation 
....Then, I will be done...At least for a little while...Untill I need more BOOST

14.7psi should double the original horsepower... so that would be 250, but on stock compression... lowering it means... yep, 15-16 psi would be right around the 500 mark at the crank

Yes i am also very interested in this shift kit as well, I actually went to a shop today and they said they would fully build my engine (rods, pistons, etc.) and twin turbo my sc for about $12,000. They will do just the twin turbo system for $7,000. I was thinkin of using twin GT25s.
