which would be better? sr20 or ka24

yes and let me enplane why, you will need forged pistons $900 stage 2 cams $800 port and polished head $500 connecting rods$400 turbo kit 3000-4500 depending on brand koyo rad $400 dual fan $400 ecu e manage plus tuning and all the labor adds up to well over $8000 so to be safe one should have 10000 to do a ka turbo set up the right way
