Hey I am in the process of finding myself a b18b non vtech motor for a n/a build I will be starting soon. Pretty new to the Honda game and would like to know if I'm building a built b18b if I will need a new ecu and harness? If so which ecu and harness works best with this motor?

 

YoU will never go wrong with hondata or AEM.

 

not to be a dick and ive done it before myself, but just keep in mind you can do a standard build like p30 or itr pistons, some 404's etc and wind up with like 180/140 if you are lucky. its a lot of motor building for marginal results. that block (ls) with a stock vtec head with anything but b16 cams will produce the same if not better results and you will get better mpg. ok, not starting a vtec vs nonvtec debate just food for though.

hondata is fine, neptune will work too. no need for aem imo. dont forget to get better gearing, either a straight gsr trans or a s4c with gsr 5th for the highway.
