The parts you're thinking of can be found on APY/APX/AMK/BAM engines. there may be others but those are the ones that spring to mind quickly.
You'll have to extend the throttle body wiring to meet, and sort out re-plumbing your servo hard line as well.
The ko4 charge pipe also won't mate up to the ko3 properly, as the ko4 sits much further towards the passengers side. Not sure how to overcome this as I've not done one before.
All the above is assuming you have an AUM/AUQ as well, as it won't work for an AGU.
For the hasstle, I'd just have a pipe going over the engine bay.
