Default How Much Boost Can I handle???

If I were to turbo my GT...How much boost can I expect a kit to offer when mated to a bone stock engine (i.e. no internal mods...just typical bolt-ons)

Another angle to this question is....what would happen if I ran too much boost on a stock engine...what can I do to prevent THAT problem from happening?

Just curious...& CRAZY at the same time!!!

Soooo many questions.... so little searches....

You can safely run 5psi on stock internals, assuming everything is in working order and the gods favor you. You probably can push it to 7psi, but then things start breaking..... Like the tranny, pistons, and so on....

As for your other question, after searching, I see that many, many people have blown either #4 piston or the #3 piston, or blown the tranny.

S E A R C H...... There is a theme here.... There is even a sticky in this forum about what happens when things go horribly wrong.
