(1) JDM version of the b20a ( i hear they make 10 extra horses
(2) You get rid of the old school b20 and get yourself the b20z and then throw a vtec head on it
(3) keep the b20a5, do up the internals and get yourself a turbo
Thats my opinion.. if i didnt waste my money on my hatch i would of built up my b20 and turboed it, but it all depends on what u wanna do and how much money u wanna spend. Other than that good luck
i dont think newer b series from civic and integra will bolt up to the 3rd gen prelude mounts without some creativity
your best bet is accept the car for what it is, a high 16 second car in the 1/4 but its really light and is fun to drive. nitrous is a possibility but itll only get u to mid to low 15's IMO it aint worth it
