Well I found this....... d16z6 vtec head with a chipped ecu,crower cam, crower retainers, crower springs, stock valves, new valve guides, ported and polished. He want's 550 for the head and ecu and 450 without ecu. I think that would be a good deal and add some hp. I think I want to save up and get it. I have a d15b7 in my car with a 4-2-1 header,a full 2.5" stainless steel exhuast with no cats just resinator and "fart" can with out the silencer,and a cold air intake with k&n air filter. Exhaust alone really helped this car. What kind of gain should I exspect from this head swap?(probably going to buy a better intake manifold also)30hp? more? What can I really do to a n/a engine after that to gain hp. Have exhaust,cold air,paln on a better intake manifold,and it comes chipped,so.......what next fuel sytem,ignition,what else could there be?? I heard you can take dsm injectors and put them in my honda.
