get a 4x4 cooler,an escos cooler or a used 500 cooler off ebay cheaply mate,stg 3 is a cracking conversion! then 3 bar,injectors and a chip,total fitting time,2 hours tops for someone with 2 left hands! unless you get a escos cooler that is cos youll have to get happy with an angle grinder to fit it in the factory place,but still easy enough
