I've posted my spreadsheet on what it costs part by part before, when it comes down to it $10-15k on a swap is pretty much whatever in the context of what it costs to run 20-30 track days a year between entry, consumables, breakage/damage, etc if you're competitive. These things are capable of running deep into the pack and anything much faster is going to be a lot more expensive to build / run.

I sold my car for asking price ($32k), I know what I paid for it originally ($25k), I know more or less what I spent after doing the fudge math of selling/buying parts (~$2k out of pocket for my swap since my car came with a good motor, Harrop SC, bunch of mods that got removed for the swap, etc), etc. Really not that bad in the grand scheme of things.
