I have a 96 formula with 130k miles. I just recently added Long Tubes a 3" Ypipe, Magnaflow 3" exhaust, new plugs, tr55's and a 160 thermo. In the Spring I am wanting to add a Procharger or a Vortech 6-10psi or so. What all would I need? 36# injectors? FMU? bigger fuel pump? a boost-a-pump? I plan on new valve springs 1.6 rockers and pushrods just because it probably needs freshened. So I am gonna save for a Procharger I just need to know if I am running 8 psi would I need to upgrade fuel components? and if so to what?

 

you're gunna kill your pistons at 8psi and 130K miles. might want to add forged dished pistons to your list and maybe better rods. bigger injectors and fuel pump. do a search in forced induction forum and you'll get tons of info.

 

Pretty much as been stated. To be on the safe side, you should change out the rods and pistons and reduce the compression ratio before going SC. You may be OK at 4-6 LBS but to do it right, I'd build it correctly .
