i think its about 8-10 psi safely. 12 is when you'll start running into problems.

its really depends on all the mods you have. First your gonna need fuel to do the turbo i believe. Then i think its like 5 or 6psi non-intercooled. Then like they said 10psi on the stock internals. Build up the internals and pretty much the engine could handle almost as much as you can throw at it.

The 420a cant hold a headgasket past 30psi for some reason. Shawn from CI was running 32psi and was blowing one every other week. The only thing to do after that is o-ring the block/head.

if you run anything over stock you should think about head gasket blowing you cant stop it but you can help by installing head studs instead of factory head bolts (they are bad about strectching) and they make head gaskets for higher pressure installations
