420a

I wouldnt run over 8psi with the stock internals. I'd run 6 on a day to day basis myself.

Do you get any signs of boost creep? If not, 8 psi is good. Don't go any higher than 10 psi on stock internals! If you do creep, how high? Otherwise, 8 psi. JL's recommendation is a good one too.

w/ a 20g turbo i wouldn't go any higher than 8lbs... thats a good sized turbo to be pushing 10lbs. a good rule of thumb for the 420as is not to go over 10psi but on a turbo as large as the 20g 8 sounds good. i'm curious about something though... you said you have what size injectors? 270cc's i don't believe is correct... and if so i don't think that would push 8lbs to be honest lol once you get a bottom end rebuild you will be good up to about 20lbs of boost before you need head work.

also should i be using a bigger inj. than 270cc???????????

absolutly!....I wouldn't think you would be able to run 8lbs of boost with 270cc. What exactly are you running right now?
