I moved your thread to the Eclipse forum since your question is very vehicle-specific and didn't really belong in the Engineering & Technical forum. You should get better responses here.

O-ring installs a SS o-ring on the deck surface of the block to seal high pressures. If the engine is known for head gaskets blowing then o-ringing it will help. Many times "o-ring gaskets" are available for popular engines.

I remember getting v-8 and v-12 done for $125-$250 , I would think that maybe $20-40 per hole might be a fair price today.

Why do you ask?

Im going to assume we are talking about a 4g63 7bolt motor. You dont need to oring the motor. Before you start talking about running 30+psi what kind of mods are you working with right now. You cant just crank up the boost and expect to make power. Boost pressure is really irrelevant, you should set a power goal to reach and then adjust boost accordingly. Say if you want 400whp then you size your turbo accordingly. Then turn up the boost till you reach that goal.
