Any collet made for .21+ engines will work fine for you. The springs depends on your driving stlye.

Actually, I ran into a problem with collets before. I have a hyper 7 pbs and when I replaced the engine with an SH, the collet that came with the SH was too thick that it made my flywheel to be too far away from the engine. I had to use my original collet instead of the SH supplied collet for things to work
