personally.
leave the truck where its at and just save for after things after college. Took me working many a side job, selling things off i didnt need, and eating top ramen to just get a built trans when i was in college. as soon as i graduated, i bought a twin turbo kit cause i was in the "gotta have more power" stages like you. motor lasted 2.5 months and bent the rods. it put a hurting on both my Gf and i at the time (now my wife) as we lived in an apartment, had debt and we were wanting a house bad. it took me over a year to save and doing the motor assembly to get my motor back built and i was still able to land a house in the middle of all that. i lucked out with the job i got and things went well but ask yourself this:
if something happens to that truck right after you buy these goodies, can you afford to fix it? if not, how you going to get around? can you wait and save enough to fix it back up again? basically, how much of a life line is your truck to you right now. you got a heck of a quick truck as it is now. the more power you make, the more other things become an issue like tcase, driveshafts, axle wrap, ect. not to say you cant get by without something coming up but the chances of them being an issues with the mileage you have becomes much higher
