Any car can get crankwalk but 2G I hear got a 50% chance or something like that. Even if you get it you can just drop a 1G motor in your 2G which is what a lot of my friends have done around here. Cost less to buy a drop in a 1G 4G63 in a 2G then it does to build a 420A. I think stock boost is 12psi but I might be wrong. Got friends running 16-17psi on stock turbo but once you get to that point its time to upgrade to a 16G or bigger w/ fuel mods. Also, some people on here have been running a stock bottom end for a long time, like Corbin who just hit three years but others like myself have had bad luck and drove maybe 3K miles. Its all in tuning, how hard you push your car, compression before you go turbo and some luck to.
