I remember from the 986 days that only the 3.4L engine would be a direct swap with no problem to fit. The 3.6L or above requires some modification, the extent of which is not clear to me.

Anyway, just thought I'd let you know. Don't know if this carries over to the 987 or not. But I understand that once you swap motors, it doesn't make sense to do it for only 15hp, so you have to go all the way.
