Welcome to the forum. I did a little research for you and you will need a zr200 oil pan. But to find one of these pans are next to impossible. I have been building custom pans for the rb swaps see my link http://forums.hybridz.org/index.php?/topic/89219-i-picked-up-a-new-sheetmetal-brake-and-other-toys-for-building-these-oil-pans/
