B16a or crower 403's

if I put a doch jdm b16a engine and tranny in my 93 ls will it be faster then if I just put crower 403’s and valvetrain in my b18a? My budget is kinda limited. My b18a has 125k miles on it and i can get the valvetrain and 403’s now but i’d need to save a while to get the b16a. Is it worth it for the b16a?
