i have an automatic 93dx with a d15b7 and i was wondering if a VTEC d-series head would fit my engine. i think the D16z6 is VTEC but im not sure. could i swap my head for a d16z6 head anyhow? i heard this is possible and if so, then i want one from a car with a manual tranny, because the cams are better right? i kno ill prolly just need to switch harnesses, wire for VTEC, and get a new chip (i kinda want a p28 or somethin anyhow). well help me out with whatever u can. thanks!
