I was wondeing, I am building the bottom end with BC rods, JE pistons, and stock stroke Eagle crank. My question is, how much boost can I put on an unsleeved b20 block? The head is also built. I am only planning on running 10 to 15 pounds of boost. Should the block be ok with that amount of boost?

 

Read the forced Induction FAQ's. Dont set a psi limit on a build, set a horsepower goal. Psi is irrelevant in most cases. Different turbos put out different power at different pressure levels. Theres a huge boosted B20 thread in this section, use the SEARCH button, theres alot of info on B20's in that thread. (thumbup)
