which would be faster inside of a crx. Just wondering if i was to run the b18b on obd-0 using the obd-0 ecu and injectors and ecu......would it run any slower?? well thanks

 

since the LS its already a B series, if u put a VTEC head later in the future u get a nice engine
if not then go SOHC VTEC....
ita all about budget basically

 

On the note of what would be faster the b18b would be the faster of the 2 motors in stock form in the car. Go for the b series swap man if money isnt a prob. However the d series does seem to be a better motor to run boost on. If your future plans involve a turbo go d series if they want natural aspiration go b series all the way.

 

there is no replacement for displacement

 

No, but money isn't very plentiful to everyone these days.
