Simple bolt straight on mate as I done this on my mates 5. Think you might need to use the IX turbo water pipes.
You can use your existing downpipe just swap the turbo exhaust elbow onto it from your standard turbo and bobs your uncle
Best to just sit both turbos side by side on a bench and you can see what needs swapping.
You still using the standard rubber air intake pipe ? If so there is a reducer inside the end that fits on the turbo which you need to remove as the inlet on IX turbo is slightly bigger
