You probably wont hit 250-300 on a d series with a jrsc. Most of the d's are compatible with each other. Good luck with the build though.
Well i was looking at Bisimoto cams, and noticed there were 2 to choose from: the y8 and the z6. Would either fit the jdm d16a? i also noticed non-vtec had the d16a6 and i wasnt sure if that may be a sub-series of this motor or not considering it has vtec.
