Does anyone know of a good 998 engine rebuild/service manual besides the general service manual? Or is the general service manual sufficient? I have some off-season high performance mods I'm going to do (e.g., new rods, pistons, cams, etc.), and if there are good 998 engine rebuild/service manuals, books, or videos, I want to review them. Not my first engine build, but would be my first 998 engine build. Thanks.
