the d15z1 is an alright motor.. im using it with boost.. but im also using a y8 head so i have the regular vtec.. but i wouldnt put a regular vtec head like the z6 or the y8 on the z1 block.. it drops the compression way too low for any streetable na power its about 8.04:1 with a y8 head and 7.8:1 with a z6 head...
what intake manifold are you using right now and what ecu?? i tried using a p28 on my friends vx once.. and it ran like crap.. when i was still na on the complete vx motor i was using a p28 that was chipped with vtec engagement at 4k and i was using the ex trans intake header exhaust.. it ran a 9.93 in the eigth mile.. wich isnt that fast. but thats still mid 15's!!!!
talk to bense or transzex on here.. i think they know where to get the vx cam reground to have some nice lobes.. but either way you WILL NEED A TUNE for that motor to run any better then it does now..
anyways.. gl with your setup and being different:alky:
