I have a apexi intake pipe, 2G o2 housing, hahn race craft FMIC and pipeing, 2G manny, rsr downpipe and catback, 680s, dsmlink etc...
I'm thinking about upgradeing to the nice Mitsu 20G. What all am I gonna need for the swap? Can I change out the head studs with out riping the head apart? I would want to run higher then 20psi with a 20G.
