The mods don't add that much value unfortunately. You can take the KBB value and maybe add 10-20% of the mod value. Mods actually take away from KBB value but most people will expect to pay a little extra for it. Usually, you can get more money by removing the mods(if they are easy enough) and selling it all separately. I'll use my old 93 Indy Pace Car as an example. I couldn't sell it for $11,000 with the supercharger on it. I removed the supercharger and sold it for $1500 and then sold the car for $10,500. The buyer knew it had been supercharged and he test drove it and thought it was still one of the best cars he had seen.
