He's spent close to 4k on parts but IMO it was worth it to be running 13's reliably @ 0psi
K20 swaps on the other hand are just too expensive right now since the price of the motor is still looming around $6k. You can make 220+ whp with K-Pro and tuning, but that will run you another $2K.
I guess it all depends on how 'm4d tYt3 jDm' you want to be
