Id go with te B18B as mentioned the torque is there. stock for stock id say youd be hanging with b16s. Plus if you do decide to go vtec later on you can always slap*well more to it than that but you know what i mean* on a b16s head on there, change to a b16s transmission. your set basically. if you plan on doing turbo later on keep the ls tranny longer gears means you stay boostin longer.
