The manifolds, turbo, inj etc will all fit no problem. Straight swap, I have them on a silvertop in a mk3 fiesta.
I am sure you will need to fit a 2 part sump from the blacktop to use the standard FRS downpipe but you may need to confirm that.
The intercooler/charge cooler setup may fit depends on what car it is going into?probably better to upgrade to a proper air to air intercooler and custom pipes etc.
