sr20det swap into 97 sentra xe

so anyway, this is my current dillema. I'm saving up to purchase an sr20det for my sentra (seems like the thing to do). But it seems all the kits are made for the 200sx or the 240sx. Any ideas on how to bypass this problem other than going all out and just purchasing one of these cars? I was considering maybe going to junkyards and looking for the 200sx specific parts i need and getting preformance parts for the car when possible instead of ordering stock. Any advice would be wonderful.
