well its an easy swap cos they use the same ecu plug
you will have to have an 8inj sub loom wired in and 10 position boost switch for the air injectors.
after that it up to you what spec engine you use?
if you use a wrc inlet manifold they cost about £400+£450 for my ecu(+postage)
then you have the option of running over 500bhp!!

engine spec:low comp pistons,ported head,high spec cams,hybred turbo 8 dark green injectors,10 position boost control switch,air injectors,large intercooler.
my engine was same sort off spec as this and i had 520bhp!.
