Is it wise/recommended to up the compression up the pistons if one is going F/I in the future? What if boost levels are not going to to exceed 7 or 8 psi?

So, keeping the stock pistons would be alright. Thats good to hear because I could use the money for other engine upgrades, like Pauter rods. These (Pauter rods) are good to upgrade to because it helps strengthen the engine internals, correct? Is a EBC or MBC needed if boost levels WON'T exceed 8 psi? How about bigger injectors or fuel pump?

First off, what kind of engine do you have in your car? If it's a 1st gen BP DOHC, then don't worry that much about the internals. They are very strong and you'd need to upgrade the rods, pistons, etc. only if you plan on passing the 400hp mark. With 8psi of boost, you'll be just fine.-------------------------
