i am now building a custom turbo for my 1998 civic that already have a gsr engine in it. The turbo is a garrett hybrid T3/t4 with a large intercooler and 2.5 inch piping i already order Je pistons and eagle rod and i was wondering what else do i need as internal to push 18-20 psi daily safely.

thanks and sorry for my bad writing im french
