I have a JDM H22 swapped into a 95 accord and recently I have been having an intense vibration while accelerating beyond 50 or so. It does not feel like a tire balance issue because the vibration is not noticable at cruising speed but the moment I flutter the accelerator the is a very noteworthy vibration. I have been under the car and nothing seems loose or damaged. I am out of ideas guys. Could it be an axle issue or is there something else is should consider before pulling an axle for no reason.

Any help or suggestions would be appreciated.

Jack the car up and check ALL Ball-Joints and Wheel Bearings. Axle is not likely the issue. Since the vibration is present under load, check you motor mounts too. Not real sure what the deal is but it wouldn't hurt to check all those things.
