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.

I've got a ported Big16G w/a larger (34mm) wastegate flapper I could let go for around $500. It's got about 4000 miles on it. I'll include the ported O2 housing, too. PM me if you're interested

hey tsi,
thats not a bad deal, I'd offer to give you my old 14b at a good price but it is still on the car, unless you want to wait untill I get a chance to unbolt it. is the turbo all you need???
