ok here's the deal. I have a dc bottom end with a built y8 head on it. All new seals and gaskets, aftermarket intake manifold and the normal bolt ons. Idles great, revs up smooth and noncheck engine lights. But when I go to drive it the car has a wicked lag. First lil but second has no power. Any thoughts?

 

DC as in Integra?

B series bottom end, and D series top end? That's probably your problem.

 

My bad I ment ZC sohc. Sorry using my phone to post
