before anybody flames you, I will help answer your question. You will need to modify or get a new oil drain flange to work with the set up or your steering rack will rub the rubber hose creating a leak. I made my own custom IC piping so I used a S13 outlet elbow (connecting to IC piping) and then I used an S14 intake pipe and made a custom 2.5" intake pipe to run between the S14 pipe and the MAF. Ideally you should also replace your hard prebent oil/water lines with braided oil/water lines as that will make it MUCH less of a head ache you will also need a .035 oil restrictor to keep your oil seals in good shape. It sounds like a lot of work for such small gains, but really its not tough, but if you have to buy the oil drain, lines, etc. and can't custom fab your own stuff, it might be a bit spendy.
