As title states. Do they swap without mods?

It's the same valve if you can alter the connector.

they swap..( plug change ) ..s5 turbo unit has a larger air feed pipe and can flow more
\
if using an s4 NA unit it is a little offset in the other direction but also bolts on
also NA unit lacks the internal user adjust screw for idle speed .. ie you have to set idle speed with the throttle stop and then recalibrate the TPS
