You will spend more swapping in the sr20 than you will boosting the ka. Now if you say that you can swap the sr20 in yourself and save on labor. Then the same person can boost the ka cheaper than swapping in an sr20. Now if your looking for 350hp or less then there is no need to build the ka just get a good tune. But if your gonna go for more than 350 then you should build the motor. But most people that I've seen with sr20 swaps have stock motors. And they didn't do the work themselves so they's spent way more swapping in a sr20 to get the same power that boosting the ka would have got them.
