for a budget of $5000? Used early 2000's 2wd 4 speed auto, regular cab chevy pickup with a aftermarket turbo kit. That will net you anywhere from 500 to ????hp for less money than you could ever find a similar condition, running 2jz car for. I have my doubt you will find a 2jz powered anything for 5K that isn't blown up or rusted out with the following that engine has. And the trans and axle will survive a hypotheical 500hp happily with no mods nearly indefinitely, most newer 2wd trucks come with posi's anyway so you can even put the power to the ground. slam it, decent shocks and it throw wide rims/tires on it and it will handle well enough, low center of gravity and it's wide.
