ok i got a jdm d15b 3 stage vtec motor its installed and running beautifully. its wired for both solenoids to hit at 5k incase anyone is wondering with a p70 ecu i believe (have to double check) it is a p2j head for sure though (y8) and was going to get the ecu chipped to get a little more power and eliminate the knock sensor cel but my main question is, is there a cam i could put in to make some more power before i chip it? also looking for complete valve train upgrade. wanna build the head for future boost. any info appreciated been searching online and cant seem to find any 3stage builds on what im looking for.


Honestly, if boost is in your future, focus on the bottom end instead. The top end won't be the breaking point most likely.
