Well first off right now I have a 305 TPI in my IROC-Z. I am converting it to a 350 TPI with this engine:

After that thing is added I want to go with twin turbos:

With these twin turbos am I going to have toe custom fabricate and Exhaust? Would this be all right for this engine? What PSI should I run? What kind of horsepower should I be expecting?

I will be doing all the work from my garage and I know a lot about cars like how they run, how they work and other stuff I am just not a pro on the details.

Another option:
Build my own engine? Go from the crank case up? Therefor I can go all forged internals. But if I went this route I would want to put the TT on my 305 until I finish building the engine. I am still in high school so I have a low income.
