D15Z1 1.5 VTEC-E ... going to be whipping this for a daily drive until feb 2008 then im swapping in a GSR but for now i was wonder what I could use to gain some power out of this ... never messed with a D series was wondering if a 1.6 VTEC cam could possibly go on this motor and gain more hp? or anything from the 1.6 VTEC. What bolt ons would be worth putting on this motor? ISO some more hp but not to much considering im swapping a gsr.
