HEy everyone I have been debating on upgrading my radiator on my after my forced induction install but everything i read it that every radiator has to be modified in order to fit on the g35 coupes.....or the ones that are close fitting the piping has to be modified....With that being said what type of oil cooler should i go with? I am also considering an oil catch can..

One last question is what should our oil pressure be sitting at around idle? Just curious because my oil pressure gauge fluctuates up and down....if anyone could help me out with these questions that would be great!
