2.2 or 2.5

I need to replace the motor in my 86 2.2 turbo lancer Pacfica(looks like a white Shelby).I thinking about a 2.5 swap.I'm going to pick up either a 2.2 or I want to go 2.5.What year motor do I use?Any reasons I should NOT use a 2.5?I already have a 2 piece intake from a VNT and an intercooler from the aftermarket.My current 2.2 in the car developed a bottom end noise today,so it's time to pull it one way or another.Any helps appreciated.Thanks Steve
