All the parts are identical. Most recommend that you either use all of one set of or all of the other. I’ve personally pieced a couple clutches together that worked great. But there are a few rules. One, always resurface the flywheel and clean it with rubbing alcohol before installation. Use some sort of thread lock on the flywheel bolts. Always get a brand new throw out bearing. As for the disc, inspect both, use the one with the most material (obviously) and inspect the springs for damage or anything weird, but don’t use cleaners on the disc at all. Wipe it down with multiple rages if you have to, but NO solvents of any kind. As for the pressure plate make sure its dust free then wipe down its surface with rubbing alcohol. Give it about a hundred miles before you start dropping the clutch and you should be fine.

As for the intake and TB everyone needs to know the ECU your going to run. There are a few ways to do this but its a question of the parts you have because i assume that money (like most people i know) is an issue.
