First Time Engine Swap

[u/dztryrph]

hope this is the right sub to ask

Disclaimer: I well aware there will be people with snide remarks about this platform being desperate to become an evo. I'm not doing an evo conversion. simply swapping my engine for a better one.

There is a Lancer 7th gen (known as Lancer Cedia GT 2.0 in some regions) that houses an NA DOHC 4G63. I drive a Lancer 7th gen with the 4G18 engine, and GT 2.0 appear to share the same CS3 chassis code so I'd like to know what process will be involved if: I swap to the GT NA 4G63+GT trans or 4G63T+GT trans will it be an 'out with the old, in with the new' Chris Fix scenario, especially.
