I have a rb25 turbo on my r32 and make 180-190rwkw depending on the day. I also have hks super dragger zorst, dump, chip remap, pod, fmic, blitz sbc iD. I run 14psi.
It is a bit laggier than the stocker obviously and the power delivery is different, its more progressive than all at once like the stocker. Pulls much harder up top than the stocker did.
