x2 B20s are notorious for weak cylinder walls. i say B20 vtec but if our rev happy its not gonna last long since that motor is built to rev aound 7000 rpm.^ and we'll see how long that last. Sorry, but if I'm spending over 3k on a motor, I'd rather not play russian roulette.
Why is this even debated? The B20 is known for its weak cylinder walls. Let's just add more compression to a stock weak block. Hey, why not throw a 3k turbo kit on it and turn up the PSI cuz that would be cool. Have fun with that blown motor.
