Boost pressure

How much boost does it take until you need to worry about installing studs and blowing headgaskets? I would like to upgrade my turbo but I don't want to open a new can of worms.

I get nervous over 40psi with advanced timing, but that's a conservative approach. It depends on the truck, but I'd say don't go over 45psi.

One of the main killers of a HG is drive presser your HX-35 has a lot of driver presser. I would get a boost elbow if your comp did not come with one and set to gate at 40psi to be safe.
