Not really more aggressive but I'm sure if you get some basic mods exhaust, intake ect it would sound better and you'll feel it a little more.. I noticed the difference in mine... What motor you running??

d16y8 3r racing exhaust aem cold air intake, and a ls tranny. and would purchasing a vtec controller for $120 and tunning the vtec be worth it? considering it being a sohc?
 

crash!

I knew what head he had I dident know what other mods sorry... Then the z6 head or doing head work would be your best bet..
I have a z6 head deffently fun =)

DO NOT PUT A Z6 HEAD ON IT, IT WILL ONLY LOWER THE COMPRESSION

youre a noob which is fine, do bolt ons and maybe a chip from xenocron or phearable, then read and learn for about a year

compression doesn't mean higher hp. in this case the Y8 head is actually designed more for saving gas that the Z6 head. its all in the runners and the combustion chamber shape. The Z6 will out flow the Y8 head.

d series is hard to build up unless you dump alot of money into it, like a turbo build or something. also the d series vtec is alot more subtle than the dohc engines. like stated before, just do some bolt-ons, read and learn alot until you know how to build it right, no sense wasting money on mods that you don't really understand.

youre half right

http://www.d-series.org/forums/naturally-aspirated/135800-z6-vs-y8-cam-head-question.html

so according to that thread there is no real difference in power between the too. Some say the z6 flows better up top and the y8 has better midrange. Since d series dont rev like b series I would think you would want to stick with the y8 on a mostly stock situation since you arent revving a stock y8 or z6 to 8500rpm

so swapping heads just to have a TINY shift in the powerband seems like a waste of time/money to me and can be better spent elsewhere, like taco bell
