Speeding up engine builds

Does anyone have any tips for speeding up engine builds?

You can try this : How to improve compile times for a C++ project? - UE4 AnswerHub

That helps speed up game builds, but not engine builds, like a tiny one line change in a string in UnrealEngine.cpp

Actually, making those changes to Engine.build.cs helps, just the first compile after the change will take ~45 minutes.
