questions about Honda B series, K series, etc.

That’s sounds about right for the swap, but you’ll most likely need to add in $1000 for hondata K-pro (to allow for tuning the k24/Type S combo and eliminating immobilizer) and $500 for mounts (unless custom fabbing your own). Also a spare set of axles would be a good idea to keep around as I haven’t checked the combinations that work in say a K swapped EK but I’m pretty sure PepBoys doesn’t stock them for those times when one happens to go and you need one like yesterday.
