B16a 90 civicHB swap
I swapped a B16a in my civic hatch, ever since around 4000 at regular acceleration it starts vibrating. It happens during free revving to. I had the OE flywheel lightened its about 10lbs. I dont know if they balanced it right or even if that is the problem.Running out of ideas of what is wrong. Anyone had the same problem or know what could be wrong .Any suggestions would be great.

Re: B16a 90 civicHB swap (Count Blah)
this happens at idle? your flywheel might have been balanced incorrectly..
just to be sure, what mounts are you using?
and did you torque them IN ORDER?

It has still got a ton of power, still pulls fine.The vibrations are not as bad when you accelerate hard.
