What are your goals?

Unless you are pretty much fully built N/A, you won't benefit much at all from a stroker kit. It will give a little bit of torque down low but the increased stroke/rod ratio will limit revability.

If you are looking at increasing displacement, Snoopy hit the nail on the head. If you are looking for some extra power, consider a vtec head swap or some valvetrain work with high compression pistons.
