d16y8 head swap.
 

Hey guys.

Im now considering maybe doing a y8 head swap for my 93" 1.6 vtec. Just a few minor questions and concerns. Im looking in to getting a Skunk2 intake manifold, do I get the one for 92-95 civics, or 96-2000? Also, I have a Holley 68mm TB at home its for 92-95 civic, would it work with either of the skunk manifolds for 92-95 and 96-2000 civic? Should I upgrade to a stage 1 cam at the same time? Do I need any thing else other than the head?
Thanks guys!

Why do you want the Y8 head if you already have vtec?

RE: d16y8 head swap.
 

itll bump compression about half a point. i think the manifold will work on either one, if theres different p#s for them, get the 96+. yeah, the TB should work fine. and yeah, go for the cam while your at it. the higher comp will love the bigger cam.

ah. gotcha.

Ok, say with the y8 head, and a stage 1 cam, how much HP and torque can I expect to gain? If all this was done on a stock 1.6 vtec.

i'd say conservatively, 20hp, but it depends on how aggressive the cam you go with is. and torque should be close to that, probably a little less, but still VERY noticeable.

haha. i guess no wonder ppl consider the D16 series to be the "mini-me" of the B16 series. 20 hp is quite impressive.

Yeah, a lot of people are just... stupid. If you don't have a B16A, no one expects you to turn any impressive numbers. But it ain't hard to show 'em with a D16...
