million

ive been lookin at f2d f2b h2d h2b for a while now and what im thinking of doing is going f2d i already have a d series in my car with 100k miles, which is actually runnin no problems the only reason i wanna do f2d is because it seems like ive been waiting so long to get a better engine in my car and im runnin out of patience to save more money. if i were to go f2b i would prolly have to save a good 2000 more for lsd tranny adapter kit mounts ect... but yea juss looking for opinions


is it a bad idea to use my 100k mile d tranny?

will it be well worth it to save up for f2b?
