after talking to my buddies dad who knows a considerable amount more than me on diesels i mentioned i wanted stage 3 injectors. I told him if i got them i would need an intercooler for my obs. he brought up an argument that the intercooler just basically lowers the egts and if i was gonna put the cooler in for that reason why not skip all the custom fab in putting in the intercooler in and just get a water/methonal injection setup. could this be a suitable substitution for the intercooler?
