132 size motors will fit if you bend the soldering tabs carefully.
The worker half dart kit is quite nice since its compatible with both half and full length darts.
Daybreaks / Kepler’s are a great option for flywheels (don’t get the worker ones imo, I’ve had some bad experiences with unbalanced wheels from them)
If you have a 2s or 3s lipo laying around those are probably the best battery for a higher powered blaster (please do read up on lipo safety)
Lastly find a friend or someone near you that can 3d print parts or get yourself into 3d printing if you’re really into the hobby, many sites overcharge for 3d printed components imo.
Just some add-ons to this in no particular order:
