whats needed for a blow through system

You need a carb prepped to work with boost instead of vacuum, you need a fuel pump capable of enough pressure to keep up with the boost and a boost sensitive fuel pressure regulator, and you need an ignition that can be dialed in to progressively pull timing as the boost comes in.

Simple, huh? LOL

and uh yeah...the turbo, wastegate and blow-off vavle....

Not true. I have my ignition set up normally but set the base at where I want it to be with boost.

Base of 20 degrees and the vac advance hooked up for a total of around 33 degrees while cruising. When boost comes on it retards back to the base of 20. Simple but effective.
