sr20det or ka24de?

I want a turbo, what is the best way to go? Turbocharging my ka24 or to swap for a sr20. The way i see it if i hook up the ka it's a bigger engine by .4 liters since its bigger will it be more powerfull than the sr20. Plus its less of a problem than to go and rip out the engine put an older engine and pray to god that the engine doesnt fuck up. What are some of you alls opinion?
