Probably not, unless you already have bigger injectors and a GSK also. If you have a 180hp setup I'm assuming you have an auto. If you haven't replaced it or done some work on it you are may develop transmission problems as the stock transmission isn't known for taking much HP upgrades from stock (actually a lot of folks have had problems without any power upgrades). You may want to consider getting a set of gauges pretty quick (transmission temp, boost, EGT) if you don't have them already. From what I've read, you should be good until about 300-350hp. Basically, watch your EGTs and if they are getting to 1300 easily or rising quick then you might need to consider a trubo/housing upgrade. Also, might want to set your timing to 15 or 15. 5 degrees.

you probably have a 12cm housing(not sure on egr engine) if your just gonna run a 10 plate id leave your exhaust housing alone. If you do deside to go bigger id go with a 14cm.
