So okay. I made a post a while back trying to figure out why the motor by roomate bought from Hmotorsonline was not living up to its potential. Well he bought the supposed JDM SiR II engine with 168 hp. Well we took it to a mechanic and this is what we were told. The guy first told us it was a sensor for throttle control not giving the proper voltage causing a lack of hp allowance. We were like cool, order the sensor and go to town. well... When the guy was calling honda looking for the sensor. He was reading off the engines numbers and this is what he was told.. The block is a 1.9L engine from a 91 Civic. the Ecu is from a 1.9L Acura that he wasn't sure of the model at that time. And it was non-vtec. The valve cover is the JDM valve cover and B16 is etched into the block. Who is full of shit?
