found the problem, need a solution Options

[TSiwrx]

the white smoke was what i though originally. my turbo is bad. it smokes terribly all the time now. here are my possible solutions:
1.) drive it w/ the bad turbo till it finally dies completely and literally smoke everyone around me on the road.
2.) get my turbo rebuilt and spent another who knows how much on that.
3.) marcus at slo pny said it would be cheaper to get a 16g. my question on this is how much is a good used/ new 16g and what will i have to accomodate the bigger turbo. i already have a 255 fuel pump, but what about a new intercooler and pipes? injectors? fuel management?
4.) i have a place that i can get a garrett T3 ball bearing turbo new for around $250. how much different is this turbo as opposed to the 14b? what would i have to do to accomodate this one?
5.) i have sitting here a mitsubishi 12a turbocharger that is rebuilt and is originally from a starion. i understand that IF this would fit, it would be a loss in power, but could get me through till i have enough money to afford something else. does anyone know if the 12a will fit or not?

any and all advice is appreciated. thanks a lot.

it sounds as though the 16g is the best bet. if anyone knows where i can get one that would be great. what should i talk to awdnot2 about? the guy at high-rev motorsports said he will sell me a new big 16g for like $700. i certainly cannot afford that. is there a place i can get one cheap? otherwise i might just get a used 14b and get it rebuilt.
