oh i see ..but still i think im going to do just for the fact of knowing theres more in there and, knowing that the head is brand new so i can trowin arp head studs while im in there and a better hg. by yeah just my .02 cents

 

It's pretty much a waste of time and money with a boosted setup with the goal you set. At most you can clean up the port castings a little bit, but I wouldn't go crazy. If you've never done any headwork at all, I would highly suggest NOT touching it at all...it's very easy to lose power instead of gain it by going buck-wild on the ports. It takes alot of practice, and unless you have knowledge of where to modify to make power and access to a flow bench to verify as you go, then just leave it alone. Besides, you're going to have to build your motor anyway to hit your goal, what's the 1-2psi extra at most you'd have to run to make the same gain gonna hurt?

 

DON'T listen to slo! Just port the ******! Bigger the better! More air = more power! One time I ported the head so nice...that all my exhast ports became one big one! I lost a bit of hp in lower rpms but my top end was OMFG!

 

Lolz...that's all I gotta say

 

Yes i hope he is joking

 

The 400 whp+ d16's Im a little um about honestly on stock top end parts. Dyno's are well not really the truth in the total sense of it all



I mean 400 whp on a stock bore b16a at 20 psi isnt that easy so how is it that a d is going to do it.


also 400 whp=10's in anything besides an integra not high 11's that seem to be the route odf these monster D's



What does that tell me there really not making that kind of power



Finally 300 whp is more than enough for 99.99999 percent of people and if you dont think it is then you havent been in a crx with that kind of power




My view is atleast upgrade the cam and run a manifold and big bore tb if your going for big #'s with the D. Hell a buddy of mine was running 12's on a small ihi probe turbo on the d15 in a fully body no cutting civic



irony it had a crower cam and some of my port work


Simple is a good flowing top end will make more power and you wont be at omg boost levels and killin turbos every couple months




Im going to bed

 

Impossible.
