Port & Polish D16y8
I had mine ported when I swaped a D16Y8 head onto my D16Y7. Not sure what gains came from porting alone, but before VTEC was hooked up it had a little more top end pull. I won't have it dyno'd until the turbo if finished in the next week or so though..
You will always see an increase in horsepower with a proper port & polish.....it is more benifical to the turbos of course but it helps in every situation.
A stock n/a d16 would probably see and increase of about 10 hp.
